How To Size A Solar System

In the solar sector, the term “solar size of the system” refers to defining the capacity of a solar panel system to generate electricity. It is typically expressed in the form of Kilowatts (kW) 1 kW equals 1,000 watts. The majority of home solar panel systems range from 4 kW to sixteen kW in size.

Solar system dimensions are the primary thing to consider when you are researching or purchasing solar panels to install on your house. It’s because it’s the dimension of your solar panel and not the solar panel’s effectiveness or the brand of equipment that determines the amount of solar power to be produced on your roof.

A solar panel system of 10 kW will generate 10,000 watts of power in Standard Test Conditions*. In real-world situations such as a 10 kW solar panel will generate less power because all of the elements will not be as perfect as they would be in a test laboratory. The total amount of electricity produced from a 10 kW unit in a roof is somewhere between 1,440 to 1,800-kilowatt hours of electricity each month.

What Are Standard Test Conditions (STC)?

These are the requirements required by solar panel manufacturers to work at their capacity also known as the capacity on the label. The solar cells should be able to produce precisely 1,000 watts of light per square meter that shines on them, and they must operate at steady temperatures of at least 77°F (25C). Each solar panel is assigned a performance rating (‘size’) under STC laboratory testing.

How to calculate your home’s energy consumption

It is possible to add up all the wattage and calculate how many hours each appliance is being used per day. However, this is cumbersome and inaccurate.

Some appliances, like refrigerators, can be hard to estimate. They have compressor motors and variable instantaneous power.

The easiest way to get it is to use the utility bill from last year, which usually shows the entire year’s energy consumption ( kWh).

Divide this number by 12 to get your monthly consumption or by 365 to get your average daily consumption.

The average US amount is 30kW per Day. However, yours will vary depending on where you live.

What number of batteries are required to power a house?

Solar System

Battery storage

Battery storage can have a significant impact on the size of a solar power plant. The following factors will determine how much solar system size it will have an impact on:

Backup power needed

Are you looking for emergency lighting that lasts for a few hours? Do you need enough solar-plus storage to power your entire house for 24 to 48 hour if the grid goes down?

While the former option won’t have an impact on system size, the second will. You need to ensure that your system is large enough to meet your daily energy needs and fully charge your batteries even on days when there’s very little solar production. A cloudy day in winter.

If your home consumes 30kWh per 24 hours, you can quickly calculate how many batteries you will need.

There are 2 types of batteries for home use

  • LiFeP04
  • lead acid

I prefer , but since lead-acid is still the most popular, I’ll use them as an example.

Deep-cycle batteries can be charged up to 80%, but it is best to discharge 50% to extend battery life.

This means we need to double how much energy is required from the batteries. It is okay to have a depth of discharge of 80% from time-to-time.

This is how the calculation looks:

Energy for 24 hours = 30kWh

30kWh in battery amp-hours (Ah) = 2500Ah (12V batteries)

Total battery capacity needed for 24 hours = 2500Ah x 2 = 5000Ah

25 batteries rated at 200Ah will be required to power this home for 24 hours.

Ways to Calculate the Size of a Solar System


PVWatts, is a free online tool created by the National Renewable Energy Laboratory of (NREL), a national laboratory of the Department of Energy. PVWatts uses historical weather and solar irradiance records to analyze photovoltaic (PV), buildings all over the globe.

Solar System

PVWatts gives you a precise breakdown of the system’s output, down to the hour, based on your location.

It is a powerful tool and can be used by solar companies to create advanced solar analyses and estimates, as well as a consumer-facing tools calculator.

PVWatts’ biggest flaw is that it doesn’t calculate solar system size for you – you’ll have to use the tool to do it yourself. It requires a little reverse engineering to do this. You will need to divide your annual energy consumption by the solar energy that 1 kW of panels can produce.

PVWatts – Pros & Cons

  • Millions of data points power the government system
  • Free to use
  • Works globally
  • The trust of the solar industry
  • It is difficult to use for the average consumer
  • Reverse engineering is required to calculate the system size
  • Price information is not available from the system
  • Lacks financial analysis

Global Solar Atlas

The Global Solar Atlas provides a summary of solar power potential and solar resources globally. It is provided by the World Bank Group as a free service to …

Let’s take this resource as an example:

Let’s assume that the house is located in Nevada USA. The average daily electricity consumption is 35kWh.

The irradiation at this site Global Solar Atlas is 6.773Wh/m2/day.

Solar System
  • Geographic Location: Nevada, USA
  • Average daily energy consumption: 35kWh/day
  • Irradiation (peak-sun-hours) for Burns, Oregon is 6.773kWh/m2 per day

PV System Losses

A working home solar system can cause losses. 23% can be lost, and this must be taken out of the solar array power rating.

Solar System

With 23% losses in mind, the energy needs are:

35kWh/day x 1.44 = 50.4kWh/day load.

Now to take into account the efficiency of the inverter, which is about 96%.

The power to be supplied to the inverter = 50.4/0.96 = 52.5kWh/day.

The average daily irradiation is 6.773kWh/m2 (also known as peak-sun-hours)

52.5kWh/day of power can be produced by:

  • 52.5/6.773kWh/m2= 7.75kW or 8kW of solar panels working at 100% capacity rating.
  • To find the number of solar panels needed, divide the wattage needed by wattage of each solar panel (say, 300 watts):
  • Number of panels needed = 8kW/300 watts per panel = 26 solar panels.

Solar company

Solar System

To make the most precise projections of solar panel production, solar companies may combine tools such as PVWatts and an in-person assessment. Reputable solar companies will gladly calculate the best solar system for your energy requirements and offer a free quote.

Solar company – Pros & Cons

  • Most accurate calculations
  • Can adjust calculations based on your requirements
  • Knowledge of local rules and regulations
  • Includes financial modeling for system size
  • Can provide you a quote for a solar installation
  • Require at least one year of electricity bills 
  • Many people prefer to get an estimate before talking to a solar company

How many solar panels are needed to produce 5000 watts of power?

It may seem obvious to you, but it is not as easy as it seems. If we were to use 300-watt solar panels then, in theory, would divide the power needed by 300, which would give 16.6 or 17 panels, if you round up.

Unfortunately, it’s not like that in the real world

Although solar panels are rated at 300 Watts, this is not the maximum you can expect from them. Instead, the Standard Test Conditions (STC) specify a level of 1000 W per square meter.

Except for the difference in irradiance all solar systems experience losses of around 23%. To account for this loss, you will need to multiply your solar panel-rated powers. This is equivalent to multiplying total power by 1.44.

  • 5000 watts x 1.44 = 7000 watts
  • Number of solar panels required = 23 panels each rating at 300 watts

Roof characteristics

The orientation (‘azimuth’) and pitch (‘tilt’) of your roof will determine the orientation and angle of your solar panels. Both factors, especially direction, can have a considerable impact on solar energy production. 

A solar array facing east or west will produce approximately 15% less output than one facing south. If you can only install on an east or west-facing roof, you’ll have to increase the size of the solar system to account for that. 

the Solar Charge Controller

Solar System

Any solar power system that has backup batteries should have the Solar Charge Controller to ensure that the batteries are not charging too much and also to stop the batteries from returning their charge back to solar panels during periods of low sunlight (i.e. the nighttime).

Because a solar controller performs its job in conjunction with the array of solar panels and storage battery, it follows that the selection and size are determined by the components.

Current and voltage are the two variables used to determine the size of solar charge controllers. The solar controller should be able to handle the highest power output from solar panels and delivering the right DC charge current and voltage to batteries.

For systems operating continuously, that is the standard industry 1.2 (20 percent extra) de-rating rate is set to protect the controller from being damaged by excessive solar panel power or current.


12-volt solar panels with a capacity of 100 W with the following electrical characteristics:

  • Pm = 100Wp,
  • Vmp = 17.5 Vdc,
  • Imp = 5.7A,
  • Voc = 21.0V,
  • Isc = 6.2A.

The solar panels described above have a short-circuit current (Isc) of 6.20A. The solar charge controller rating for four solar panels rated at 6.20A

4 x 6.20 x 1.2 = 29.76A, or 30 amps.

A solar charge controller like the one pictured above should be rated at 30 amps at 12 volts or more.

Key Takeaways

  • When sizing solar panels, consider how much electricity your home uses.
  • To find the PV system that is most in need of replacement, use the utility bills monthly average.
  • A 5000 kW system suffices for an average American home.
  • A solar energy system’s installed cost can nearly double if a battery bank or other storage device is required
  • To save money on solar costs, you can use your old electric bill to identify ways that electricity consumption can be reduced.
  • How much electricity is used by the air conditioner? To spread the load, it’s a smart idea to install soft-starts ( National Renewable Energy Laboratory).
  • The next step is to determine how many hours of sunshine per day. How much solar energy can you generate for each square foot with solar panels mounted at the average radiation level in your location?
  • The peak sunlight hours are very important in calculating solar size. Sunny days can come and go so the average solar hour across the seasons is the figure you should use
  • How large is your roof in square feet This factor, along with the amount of sunlight, determines the size and output of your photovoltaic system.
  • The peak hours and solar system size give you a rough estimate of how much solar power will you have


How Long Will It Take To Get Solar Panels To Earn Enough Money To Pay For Their Own?

between 5 and 15 years old

Solar panels will pay for themselves over time in the form of saving your money from electric bills as well as, in certain cases making you money through continuous incentives. The payback period for solar panels is between 5 to fifteen year within the United States, depending on the location you reside in.

What Are The Main Factors That Determine The Ideal Size Of Your Solar System For You?

  • Usage
  • Available sunlight
  • Weather and solar insolation
  • The characteristics of the roof
  • System losses
  • Storage for batteries

Can You Walk On Solar Panels

Can You Walk On Solar Panels

Making the switch to a greener energy source, such as solar panels is always a wise choice. It provides additional support to your roof, reduces the carbon footprint of your home, and cut down on your energy costs. While it can provide many benefits but the upkeep of these panels can be difficult. It is also necessary to take care to clean them frequently to stop dust from building up and affecting the effective storage of your panels.

One tip that you’ll find frequently on maintaining your panels in top working condition is not to walk across solar panels. Experts suggest that you should not take this step. Our article will help clarify this confusion and clarify the reasons for the reason why experts aren’t getting in the way of this producer of solar energy.

What is the maximum weight solar Panels Take on?

In the beginning, it’s crucial to realize that there are a variety of varieties that solar panels come in but not all of them are equally robust as the other one. For example, thin-film flexible solar panels are not as durable and robust as standard crystal silicon panels.

The glass on the top of PV modules is designed to shield it. It’s made with specific specifications to resist damage. It can withstand a few tonnes of snow blows from hail or dust particles as well as endure the force of hurricanes.

The majority of solar panels can withstand a maximal weight ratio of 75 pounds for each square inch (psi). Since the typical PV panel measures 65 x 39 inches (2,535 square. in) The PV module is able to be able to withstand around 190lbs that’s a bit below the average weight of an individual and therefore possible to walk over it without causing damage. If you weigh more than 200 pounds should not stand on the solar module since there is a greater chance of breaking the glass.

How Can Solar Panels Get Damaged by Walking on Top of Them?

Solar Panels

There are many ways to harm a panel or decrease the power output. This, when considering the solar panel’s cost isn’t worthwhile. This article explains the various harm you can do to PV modules by walking over them.

Exceptions For Marine Solar Panels

There are marine panels specifically designed to be walkable and designed to endure the harsh marine conditions, however they don’t work well for commercial or residential roofing surfaces.

Smudging the Glass

In certain instances there is a reduction in power output from a PV system walking across a module may result in the scratched glass. Based on how deep and deep the scratch it will result in reduced output of your solar panel. In order to fix the issue, it is necessary to contact an expert to fix the damage and replace the entire glass of the panel.

Scratch the Glass

In certain instances, there is a reduction in power output from a PV system walking over a module could be a sign of scratched glass. Depending on the depth and severe the scratch it will result in an increase in the output of your solar panel. To remedy this issue you must contact an expert technician to fix the damage and replace the entire glass of the panel.

The breaking of a Solar Cell

If the weight you place on the top of your PV module is excessive it could damage or damage a solar cell. The majority of the time, in 60% of instances that a solar panel is damaged, there’s an immediate reduction in the power output of the PV module’s performance, leading to a reduction in voltage or a reduction in power overall. When the panel is not wired with microinverters or optimizers, there could be a continuous reduction in the energy output of the system. Your insurance provider may pay for this loss in the event of a lucky strike If otherwise, you’ll need to take the necessary steps to repair or replace your panel.

Breaking the Busbars between Solar Cells

While a damaged solar cell can affect the efficiency of the system should you cause damage to the busbars that connect the solar cells that are between them in a PV module, the system will be severely affected. This could be a huge issue in the case of a grid-connected solar array because you’ll be many hours without electricity until you resolve the problem.

Busbars that connect solar cells ensure the flow of electricity from one solar cell to the next and also from each panel. The majority of modules come with multiple conductors to guarantee the proper circulation of electricity, without overheating the module.

If you break one tire that connects the solar cells there’s a chance of the solar module will begin to overheat due to this. You must disconnect the panel or the entire string and then replace it to resolve this. If you damage several busbars, your entire PV string could be disconnected because of the interruption of flow that is creating an open circuit in the PV system.

Do you have to be careful walking in the Solar Panels?

Solar Panels

If you’ve put solar panels on your rooftop, you might think about walking over them to repair them in the event that they fail. You might also decide to walk on them simply because you feel proud owning one and taking a step to protect the environment.

Whatever the reason what are the rules to walk on solar panels?

Do you risk getting burned if you walk across solar panels. In addition are they likely to be damaged if you put too high stress on them.

For the answer to your second query No, you will not be electrocuted. They are safe to stroll on. But, it’s advised against walking on the sun-drenched panels because of a number of reasons. The first reason is that solar panels can be expensive. If you walk across the frames of solar panels or on cells, they could be scratched or damaged. If a cell becomes damaged and damaged, the potential for the power it produces to decrease grows.

Furthermore, in the event of diverse weather conditions and natural disasters even a tiny crevice could grow in size because the continual thermal contraction or expansion will cause the surrounding material to break. In the end, when you consider how much they cost and how difficult they can be to set up or maintain, it’s too risky of damaging one.

Can Solar Panels Break?

Solar Panels

The answer is straightforward. Yes. They could break and there are a variety of components that can make your fully efficient and energy-efficient machine fail or even be broken. For instance, if you walk across solar panels. This is explained clearly in the earlier section. For more details dependent on the type of materials that you use in your panel, and the weight you carry, it can actually damage the solar cells, causing them to become less efficient.

It’s even more dangerous If you’re wearing any type of footwear onto the panels. The dirt on your soles (like rocks or shards) could cause scrapes or scratches on the panel’s surface that can cause the panel to deactivate cells.

Another cause is natural calamities. Hail, in particular, can result in microcracks forming within your panels. These cracks are not visible to the eye but could cause serious harm to your panels when they are accumulated. The snow can also alter the thermal conditions of cells, which can cause their degeneration in terms of performance. Extreme temperature fluctuations can cause damage to or even break the panels.

Additionally lightning and storms are not a choice. Sure, the performance of solar panels declines over the course of time. In light of the above factors, do you risk more when walking across solar panel cells, instead of maintaining them for at minimum 25 years? Most likely not.

Can a broken Solar Panel Work? and How do I fix a damaged Panel?

So, what do you do in the event that you break the solar panel while running over it? Did you ruin your investment? The answer is dependent on the amount of damage that incident has caused. In most cases, the homeowner’s insurance will pay for the damages. If just one cell has been damaged or damaged, you might have to replace just the damaged cell, which is not likely to cost you an excessive amount.

If you’re an authority with panels or are able to complete the repairs by yourself, you can follow the old-fashioned method of cleansing the surfaces using denatured alcohol before applying UV-resistant two-part epoxy to close the cracks and also waterproof the panels. This process, however, requires extreme diligence.

Solar panels don’t completely stop working since you scratched on them having walked on there. There could be a reduction in the output of power, however around 10% to 20%. If you’re looking to determine how damaged they are then you can take an assessment of the voltage that is across the tabs on the cells. If they’re not severely damaged it’s possible to get between 85% and 100 % of the rating voltage.

If the damaged or cracked cell didn’t cover the entire surface the waterproofing process can be the solution. The most serious scenario is when the entire panel has a replacement. Microcracks usually are covered under the warranty. Therefore, you could check them out with an expert to ensure a more efficient repair.

Do I need to walk onto the Solar Panels in order to Decontaminate Them?

If you’re seeking to conduct a clean-up of your solar panels and seek advice on how to do it, this section is ideal for you. Here are some helpful tips for performing cleaning and maintenance on your PV system, without risking the PV modules or employing an expert service.

The first step is to purchase the correct solar panel cleaning equipment. Here’s a list of what you’ll require:

  • Lint-free cloth.
  • Soft pad, with an extended pole.
  • Non-abrasive cleaner
  • A low-pressure hose with a water supply

After you have taken your tools ready for cleaning your solar panels, how do you proceed should you do? Use these tips to cleanse your PV modules:

  1. Make sure to clean your panels in the afternoons or evenings when they’ve cooled.
  2. Apply water to the panels, allowing them to scrub off the loose particles.
  3. Spray non-abrasive cleaner then use the soft pad and an extension pole to wash the glass.
  4. To make borders, apply the lint-free cotton cloth as they’re very delicate.
  5. Then utilize the sprayer to water the panels, and then scrub off the debris.
  6. Examine for cracks.


Although solar panels are able to withstand the weight of a large amount and it is possible to take a walk over them, it’s not advised. Numerous factors could result in damage to panels in the PV system, and the risk isn’t worth the risk. While you are able to cleanse your solar panels on your own, however, we only recommend walking around the PV system or to hire certified technicians to do the repairs and maintenance needed on the roof, to avoid damage to it.


Can You Sit On Solar Panels?

A solar panel could have the same weight as in the event that you stand on them, which is why it’s not recommended that you stand on a solar panel.

Do I Need To Walk On The Solar Panels To Clean Them?

While it’s definitely feasible to walk on the solar panel, this isn’t advised. Solar panels are made from extremely thin and fragile glass. The impact and force of a step can easily break the glass or even pop it from its frame.

Can You Be Electrocuted By Walking On Solar Panels Or Solar Cells?

No, you won’t get electrocuted. Consider a solar panel similar to another device.

Do Solar Panels Need To Be Serviced?

The only routine maintenance required for solar panels is cleaning them and annually examining them. As long as your panels function well, they don’t require regular maintenance all throughout all year.

Will Walking On A Solar Panel Void Their Warranty?

Walking on solar panels could invalidate your warranty in the event that damages occur. In addition, hiring non-licensed technicians to clean or work on them could invalidate the legitimacy of your warranty claims.

How Do Wind Turbines Work

How Do Wind Turbines Work

How do wind turbines work? Wind turbines appear like propellers from an aircraft spinning around but doing nothing. They serve a crucial function, but. Wind energy is stored and their huge rotors absorb some of that energy and instantly convert it to electric power. Have you ever taken the time to think about what the wind turbines do? Let’s look at it from a different angle!

What Is Wind Energy?

Wind turbines are based by following a basic principle and instead of using electricity to create the wind like a fan, wind turbines make use of wind to create electricity. The wind turns the blades of a propeller around a rotor that rotates a generator, which produces electricity.

Wind is a type of solar renewable energy resulting from the combination of three simultaneous events:

  • The sun has a way of unevenly warming the atmosphere.
  • Surface irregularities on the earth
  • The earth’s rotation.

The patterns of wind flow and speed differ widely throughout in the United States and are modified by the presence of bodies of water, vegetation and variations in the terrain. Humans make use of this wind flow, also known as motion energy for a variety of uses including sailing, flying kites and even for generating electricity.

The wind’s power for many thousands of years. Wind has moved boats across the Nile River, pumped water and milled grains, helped with the production of food and so on. Today the renewable energy and power of the natural air flow known as wind are harnessed at a massive scale to generate electricity. A modern, offshore wind farm produces eight megawatts (MW) of power sufficient to provide power to nearly six houses in a single year. Onshore wind farms produce hundreds of megawatts. This makes wind power one of the most efficient, cost-effective, and easily accessible sources of renewable energy on earth.

Wind energy is one of the largest-scale, lowest-cost green energy option, and is the most significant renewable source for renewable power in the U.S. today. There are more than 60,000 wind turbines that have a total capacities of 105.583 megawatts (MW). This would provide power to greater than 32 million households!

Cumulative Capacity of Wind Power Plants
Source: GlobalData

Apart from being a crucial component of our energy supply. Wind energy solutions aid commercial businesses in meeting the renewable energy goals and requirements to provide reliable, sustainable energy.

Wind turbines converts the energy of wind into electricity by using the aerodynamic force generated by the rotor blades. They function like an aircraft wing or helicopter rotor blade. When the wind moves across the blade, air pressure on the one part of it diminishes. The difference in pressure between both sides causes both drag and lift. The force of lift is more powerful than drag and that makes the rotor spin. The rotor is connected to the generator in either direct (if it’s an direct drive wind turbine) or via an axis and a set of gears (a gearbox) which speed up the rotation. This allows for a more compact generator. The transfer of force from aerodynamics to the an engine’s rotation creates electricity.

Types of Wind Turbines

Big and small wind turbines are divided into two categories determined by the orientation of the rotor. Horizontal-axis as well as vertical-axis turbines.

Horizontal-axis turbines


Are the most popular type of wind turbines in use today. This kind of wind turbine is the first thing that comes to mind when you think of wind power, and has blades that resemble the propeller of an aircraft. They typically have three blades. The higher the turbine’s height and longer the blade, the higher the amount of electricity produced.

Vertical-axis turbines


Appear similar to an eggbeater rather than an propeller of an aircraft. The turbine’s blades are connected at the top and the bottom of vertical rotors. Because they don’t work the same way as those with horizontal axes they aren’t as common in the present.

Offshore wind farms are huge bodies of water such as lakes and oceans. They are funded by the U.S. Department of Energy is currently financing projects to enable offshore wind development within U.S. waters.

What are the most important components of wind turbines?

  • Turbines

While we often talk about “wind turbines” they are just one component of the machines.

  • Gearbox

In the case of most (but but not always) turbines, a second important element is a gearbox. The gears transform the slow motion of the blades’ spinning to a faster speed, turning the drive shaft fast enough to supply electricity to the generator.

  • Generators

Generators are an important component of all wind turbines. You could think of it something akin to an enormous, enlarged variant of the motor that is on the bicycle. If you are riding on a bicycle, the motor connected to the back wheel turns around, generating enough energy that a lamp will light up.

The same process occurs in the wind turbine, but that the “dynamo” generators are powered by the turbine’s rotor’s blades instead of a bicycle’s wheel. The “lamp” will be the source of light at the end of a road, miles away from where someone lives. In actuality wind turbines employ various types of generators that don’t look similar to dynamos in any way.

How do wind turbines work?

Wind turbines work

  • Wind direction

The wind (moving air that is containing the energy of kinetic energy) can be seen blowing towards the turbine’s blades on the rotor.

  • Blades

The rotors rotate and capture some of the energy of the wind and then turning the drive shaft centrally that is supporting them. While the edges of the blades are very swift however, their main axle (drive shaft) the rotors are attached to turns rather slow.

  • Rotor

In the majority of contemporary turbines, blades of the rotor can rotate on the hub towards the front, so that they are in contact with the wind on the ideal angles (or “pitch”) to maximize taking advantage of energy. This is referred to as”pitch control.

On large wind turbine, tiny electrical motors or hydraulic rams move the blades in a circular motion under strict electronic control. On smaller turbines pitch control is typically entirely mechanical. However, many turbines come with fixed rotors, and have no pitch control.

  • Gear Box

Within the nacelle (the principal structure of the wind turbine, which is on the top of the tower in front of the blades) The gearbox transforms the slow-speed rotation that occurs on the shaft for drive (perhaps sixteen revolutions in a minute, or rpm) to high-speed (perhaps 1600 rpm) rotation that is fast enough to ensure that the generator is driven efficiently.

  • Generator

Its generator is located directly behind the gearbox the kinetic energy generated by the spinning drive shaft and transforms it into electricity. Operating at its maximum capacity typically, a 2MW wind turbine generator can produce 2 million watts at around 700 volts.

  • Anemometer

Anemometers (automatic speed measurement gadgets) along with wind vanes that are located on the underside of the nacelle offer measurement of the speed of the wind and direction.

  • Yaw motor

With this method, complete top of the engine (the nacelle and rotors) can be rotated using an yaw motor that is mounted between the nacelle and tower, so that it is facing directly towards the wind, and thus capturing the highest amounts of energy.

  • Brakes

If the wind is too strong or turbulent brakes are put in place in order to prevent the rotors spinning (for reason of safety). The brakes can also be applied in the course of regular maintenance.


The electricity generated by the generator is carried through a cable which runs into the interior of the tower of turbine.

An up-grade transformer converts electricity to approximately 50 times the voltage, allowing it to be effectively transmitted to the grid (or to nearby structures as well as communities). If electricity is flowing into the grid, it’s transformed to a much greater power level (130,000 volts or higher) via a nearby substation which is used to power many turbines.

Homeowners enjoy clean and green energy. The turbine has not produced any greenhouse gas emissions or polluting while it was operating.

Wind continues to blow over it, however at a lower energy and speed (for reasons to be explained below) and more turbulent (since that turbine is disrupting the flow).

How do turbines maximize energy harvesting?

If you’ve ever stood under an enormous wind turbine, you’ll be aware that they’re enormous and are positioned on towers that are incredibly tall. The bigger the rotor’s blades, the greater energy they will extract by the breeze. The massive blades (typically 70m or the equivalent of 230 feet in diameter which is around 30 times the size of an Eagle) increase the force of wind as an axle axle and wheel so a mild breeze can cause the blades to turn.

Yet, wind turbines are idle for about 14 % of the time and the majority of the time they do not produce the most power. This isn’t a disadvantage however, but rather an inherent characteristic of their design that permits them to operate effectively in the ever-changing wind. Consider it as this.

Cars don’t move at high speed constantly The engines and gearboxes power the wheels as fast or slow as is needed to keep up with the speed of traffic. Wind turbines are like this as cars: they’re engineered to function effectively at different speeds. Alternatively, a wind farm or a single wind turbine can generate electricity that is used privately by an individual or small set of homes or businesses.

A typical wind turbine nacelle measures 85m (280 feet) above the ground. That’s about 50 tall adults sitting on the shoulders of one another! There’s a valid reason for this. If you’ve ever been on a hill that’s highest point in the entire area and you’ve noticed that wind speeds up when it’s free of trees, buildings and hills, as well as other obstacles at ground level.

Therefore, if you place the blades of a turbine’s rotor high on the horizon, they will capture much more energy from the wind than they do lower down. (If you place the rotor of a wind turbine two times as high the turbine will typically produce approximately a third of the power.) This is the reason why wind turbines are made for.

Energy harvesting
How do turbines maximize energy harvesting

Because the blades on wind turbines are turning and generating energy, they contain kinetic energy that is what they “steal” away from wind. This is a fundamental rule of the science of physics (known in the field of conservation of energy) that you cannot create energy from nothing. Therefore, the wind has to slow down a bit when it is passing by the turbine. It’s not a major issue since there’s always additional wind chasing after! This can be a problem when you plan to construct an wind farm. Unless you’re in an extremely high-wind area, you’ll need ensure that each turbine is at a reasonable distance from the other ones close to it so that it doesn’t get directly affected by the wind.

How much electricity does the Turbine Produce?

It depends. The size of the turbine as well as the speed at which the wind moves through the rotor blades decide how much electricity generated.

In the past decade the wind turbines have gotten higher, which allows for larger blades as well as the capability to make use of more wind energy sources at higher levels.

To put things into perspective For a better understanding: A wind generator with approximately 1 megawatt of power could provide clean energy to around 300 homes per year. Wind turbines on onshore wind farms usually produce between 1 and 5 megawatts. The speed of wind must be nine miles an hour or greater for the majority of utility-sized wind turbines to generate electric power.

Every type of wind turbine has the capacity to produce maximum power with a variety of wind speeds, usually between 30 and 50 miles an hour. But, if the wind is blowing slower it will decrease production in a rapid manner instead of stopping completely. As an example the wind energy produced is reduced by an amount of eight when the wind speed drops by half.

But what happens if there’s no wind?

Many people are concerned that, because winds are extremely variable it could cause us to go without power and end up in the midst of a “blackout” (a massive power cut) when we depend on it too heavily.

The real-world reality of wind is different. “Variable” is not a synonym for unstable or unreliable. In any location the power source is a complicated grid (network) comprised of complexly linked power generation units (ranging from massive power plants to tiny turbines for wind).

Utility companies are adept at balancing power generated from numerous locations with a variety of different methods to meet demand (the total power consumption) in a manner that fluctuates in time from one hour and from day to day. The power generated by any turbine is subject to fluctuation when the wind increases and falls, however the power generated by a multitude of turbines spread across the entire country, is more consistent and predictable.

In a place like the UK there is almost always windy in one area. According to Graham Sinden of Oxford University’s Environmental Change Institute has shown that the effects of low wind speeds are felt by over half of the nation but only 10% of the time.

For 60% times, 20% of UK is affected by low winds; and for only an hour per period of time is 90% of the UK being affected by low winds (Sinden 2007 figure 7.). Also having a lot of wind turbines scattered throughout locations ensures a constant supply of wind power practically all the time.

Should You Consider Wind Energy Solutions?

Wind power generation remains among the smallest carbon footprints of any energy source. It plays an essential role in the future of our nation’s energy supply, supporting our world’s energy transition and the increasing demand for sustainable energy resources.

Wind is also one of the best methods for corporations, universities, cities, utilities and other organizations to quickly shift to emissions-free energy at scale. One virtual power purchase agreement (VPPA) can secure tens to hundreds of megawatts of net zero electricity for 10 to 25 years. Most agreements also tick the box for additionality, meaning net-new clean energy sourcing displacing potentially older, higher-emitting energy sources.

Which is the best location for a wind energy project?

Here are six key considerations when considering wind energy projects.

  • Wind availability and preferred locations
  • Wind energy technologies office
  • Environmental impact
  • Renewable energy generation requires community input and local needs
  • Favorable policies at both the federal and state levels
  • Land availability
  • Connectivity to the power grid

Permits must be obtained before any wind power installation can be started, just like commercial solar PV projects. This crucial step will determine whether the project is financially feasible and has a low-risk profile. The goal is to have commercial-scale wind farms supplying electrons to the grid for many decades. It is important to ensure that the builder and project are financially sound. This will ensure that they succeed for many generations.

In summary

  • Very low carbon dioxide emissions (effectively, zero once constructed).
  • There is no water or air pollution.
  • Drilling and mining have no environmental impact.
  • No fuel to pay for–ever!
  • Wind is completely sustainable–unlike fossil energy, it will never run out.
  • Turbines can be used anywhere there is wind, unlike fossil fuel deposits which are only found in certain areas.
  • Wind energy operating costs can be predicted years ahead of fossil-fueled power.
  • Wind energy prices and political volatility in oil and gas supplies from other nations can be avoided.
  • As fossil fuel prices rise, wind technology matures, the prices of wind energy will be more competitive.
  • Construction, operation, or manufacture of turbines are all new jobs
  • High upfront cost (just like large fossil-fueled or nuclear-powered plants).
  • Wind energy requires economic subsidies to be viable. However, other forms of power are also subsidised economically because they don’t have to pay the environmental and social costs.
  • The additional cost and complexity involved in balancing variable winds power with other forms is not included.
  • Although the upgrade of the transmission and power lines may incur additional costs, the system is often in the best interests.
  • Variable output is a problem, but it can be reduced by wind farms being located in different regions and (in Europe) using interconnectors to connect neighboring countries.
  • Large land takes–though at most 95 percent of wind farms land can still be used as farming land, and offshore turbines are possible to be built at sea.
  • The only way to supply 100% of a country’s electricity all year is with fossil fuels, nuclear and hydroelectric power.
  • People who work in drilling and mining are losing their jobs.

Wind vs Solar


How Does A Wind Turbine Works Short Answer?

Turbines capture the wind energy using their propeller-like blades. They act like an airplane wings. As the wind blows, a low-pressure pocket forms on one side. This pulls the blade towards it, making the rotor turn

What Are A Wind Farms?

A wind farm, or wind park, is a group or combination of wind turbines located in the same place that produces electrical energy.

Why Are Wind Turbines Usually White Or Pale Grey?

Wind turbines are usually white or very pale gray. This is to keep them as unobtrusive visually as possible. It is being discussed whether they should be painted in other colors, especially green, to better blend with their surroundings.

How Strong Does The Wind Need To Be For A Wind Turbines Work?

Turbines can only be powered when the wind speed between 8 to 55 miles per hour (mph), 2. The wind turbine blades will resume normal operation once the anemometer has measured speeds below or equal to the turbine’s cutout speed.

Where Are Wind Farms Located?

Wind farms are often located at the top of a mountain or in an otherwise windy area to benefit from natural winds

Are Wind Farms Bad For Birds?

Wind energy is good for birds, but wind power plants can cause harm to birds by direct collisions with turbines or other structures (including power lines).

Who Does Wind Turbine Maintenance?

A technician who works with wind turbines is also called a windtech. They install, maintain, repair, inspect, maintain, operate, and test them. They can diagnose and repair any problem that might cause the turbine’s unexpected shutdown. A windtech’s average annual salary is $54,160

How Does Leasing Solar Panels Work

Leases on solar have helped make solar affordable to homeowners who may not be able to put solar panels to their rooftops. Before, solar panels were expensive enough that it was virtually impossible for homeowners to pay for the installation.

That’s where solar leases changed the solar business. Through the option of a lease, homeowners no longer need to be concerned about the initial cost of solar energy and could enjoy all the benefits of it with monthly lease payments.

However solar panels are today 70% cheaper as it used to be a decade ago, which means other financing options for solar which can offer greater solar savings than leases more practical. Also even though there aren’t any upfront costs for a solar lease does not mean that it’s the most efficient option to go solar..

In this article we’ll discuss all you must learn about solar leases to help you decide whether this option of financing is the best choice for you.

What is the solar lease?

The leasing of solar panels is sort like leasing a car. The monthly installment to a solar installer however, you don’t have ownership of your solar panel. In exchange, you will receive all the solar energy panels generate, which helps cut the cost of electricity.

In essence, you’re swapping the electric bill you pay to your utility provider for the cost of an lease company that is solar.

Typically, a solar contractor works with a leasing company to provide the solar lease. The installer is accountable in the design, installation and maintaining their solar arrays.

Does a solar lease differ from an solar PPA?

olar lease differ from an solar PPA
Solar PPA vs Lease

The solar lease and the solar power purchase agreement, generally referred to as solar power purchase agreements are very similar to options for financing solar.

For both solar leases as well as PPAs Solar developers install solar panels on your roof which is not yours to own. Instead you pay each month for the solar energy the panels generate.

In the case of a solar lease you pay the same amount regardless of the amount of solar energy is generated by the system. When you sign an solar PPA your contract will specify a price for every kilowatt-hour (kWh) from solar energy produced. The solar PPA rate will be less than the rates you pay for utility services.

If you have the solar PPA, the monthly amount will be based on the amount of electricity that solar panels generate. If you lease solar, your lease payment will be identical regardless of solar output.

How does a solar lease work?

When the solar energy system is in place it is possible to utilize all the solar energy generated by the panels. Instead of relying on energy from your utility your home will be powered by the energy solar panels generate.

Since you’re making use of solar energy rather than using electric power directly from the grid, you’ll find your electricity cost will be lower. If your solar panels produce enough energy enough to cover your energy use via net meters it is possible to totally eliminate the electric bill (besides the fixed costs that solar panels can’t offset).

However, you’ll need to make your solar lease. The lease payment will be less than the cost of your utility bill prior to installing solar. If your electricity bills are $150 per month and your lease is $100, you’ll save $50 per month by signing the lease for solar.

Remember, however that solar panels could not always produce enough power to pay for the entire electricity bill. There might not have been many days of sunshine in one month, or you used more electricity than you normally do. In these cases you may have to draw more power out of the grid, to satisfy your power requirements. In the end, you’ll be faced with an electric charge as well as the payment for a solar lease.

What are the conditions of the solar lease?

Each lease agreement with solar differs, but the terms of the contract tend to be the same.

The length of leases for solar typically range between 20 and 25, which are approximately the time span for solar panels. The solar company will typically provide a solar monitoring app on your phone or online so that you can monitor the way that the solar panel is working. Find out more about different solar monitoring software here.

The company that developed the system will also be monitoring your system to ensure it’s working as it should. If there’s any problem in your solar panel’s performance the solar company will be accountable for any repairs, without cost to you.

Solar lease contracts include an escalator for price to reflect the rising electric bill, which means that your lease payments will increase every year. The escalator is usually between 1and 5 percent.

If you’re planning on moving, many solar companies will permit you to transfer your lease over to new homeowner or to end the lease and take away the panels. After the expiration of your contract, you’ll be able to or renew it or remove the panels, or buy the panels for fair value, or at a price clearly stated on the lease.

Pros and Cons of Solar Panel Leasing

Pros and Cons of Solar Panel Leasing

There are many pros and negatives associated with solar panel leasing. In this article we will provide the top aspects, and allow you to compare them and assess the benefits of leasing solar panels could provide you with.

  • Zero upfront costs
  • Lower energy costs
  • Not responsible for system maintenance/monitoring
  • A monthly lease payment that is predictable
  • Not eligible for the federal tax credit, or for certain state and local incentives
  • Savings on long-term costs are lower when contrasted to buying the system
  • Price escalator
  • There is no added value to the property.
  • Home selling is difficult


Benefits of solar leases

Zero upfront costs

The greatest benefit of leasing solar panels is the fact that you do not need to fret about the expensive cost of an initial solar panel system to enjoy the advantages from solar power. Many solar leases are no-down and therefore you don’t need to be concerned about an enormous amount of money.

Lower energy costs

Solar leases can give you electric bill savings since the payment for leases are (initially) intended to be lower than your electric bill would be.

Not responsible for system maintenance/monitoring

If you sign an agreement with a solar company the lease does not entail responsibility for the care and maintenance of your system. Although this might sound appealing initially, it’s not as any benefit. They are extremely low maintenance and require a wash out with the hose 4 times a year .

The more serious problems, like defective wiring or problems with inverters will likely be covered under the warranty of the installer or manufacturer damage that result from storms might be protected by homeowners insurance.

You would get these safeguards when you make a routine purchase of solar panels in any case.

A monthly lease payment that is predictable

You’ll always know what the lease payment is going to be due to the fact that it is written in your lease contract. This will make it easier for you to calculate the monthly costs.


Advantages and disadvantages of a solar lease

Tax credits are not available or other solar incentives

When you sign a lease for solar it is not possible to take advantage of any solar tax credit since you’re not the owner of solar panel. Thus you will not be eligible for the 26 percent federal solar tax credits is given to the solar company – not you. State credit will also be paid to the solar company.

Furthermore you’ll not be able to benefit from other solar rebates and incentives such as SRECs which could be a source of a lot of extra cash into your pockets.

Lower long-term savings 

The main drawback to leasing solar panels is that your savings over the long term are significantly lower you compare it to purchasing solar panels. When you purchase a solar panel instead, you will have the possibility of eliminating the entire electric bill, and don’t need to worry about other monthly bills.

Even if you get an installment loan to purchase solar panels, in the end you’ll be able to pay back the loans and then the solar panels will become yours. That means they’ll provide electricity absolutely free! Solar energy that you generate can lower your electric bills and you’ll no longer be required to pay lease fees or lease fees – just free energy.

When you lease, you’re bound to making payments for period of 20-25 years. Through that period the amount you pay for lease payments could be greater than what the system would be worth to begin with! The electricity that the panels produce will never be cost-free.

Price escalator

Solar leases will have price escalators in order to reflect the rise in prices for electricity. There is however no way to know how much electricity will rise until the time it occurs.

The majority of solar leases include an escalator ranging between 1 and 5 percent per year. If your solar lease costs 100 dollars in the first year it will rise by 1percent in Year 2. However, if the electricity bill doesn’t increase this much during a particular year, you may be paying more for your solar lease than you would have spent on the electricity you get through your electricity provider.

No added property value

If you buy solar panels and panels, they enhance its value. house. When you lease them solar panel, they don’t add any value as you’re not the homeowner.

It can be difficult to sell your home

In addition to leasing solar systems that do not add value to your home They can make it more difficult to sell your house.

A small percentage of potential buyers won’t wish to sign the lease contract contingent around your consumption of energy. In addition, many prospective home buyers might get confused with the idea the solar lease instantly turning them off the thought of purchasing your house.


Is there a better solar financing option than a solar lease?

Solar panels are less expensive than they’ve ever been but this doesn’t mean that it’s not costly. The typical solar panel within the U.S. will cost somewhere between $14,000 to $16,000 after the federal tax credit for solar is used. It’s not pocket money.

While solar remains expensive but the lower price allows you to take loans to pay for expenses. The idea of taking out a loan have the potential to work for solar because the price was too expensive, so it wasn’t financially feasible to finance it with loans. This is the time when solar leasing started to gain traction.

The cost of solar power systems is not so high that homeowners are able to borrow money to finance the installation. The solar loans similar to credit for equity in homes, let the installation of solar panels without needing hundreds or thousands of dollars at one time. Instead, you pay monthly payments to the loan is fully paid. After you’ve paid off the loan amount, your panels become totally yours and will provide electricity to your home for free.

Additionally the fact that when you get the loan for solar, you become the sole owner of the system. This means that you are able to profit from all the tax incentives as well as other solar rebates that you cannot be eligible for through leasing a solar system.

The majority of solar loans have no down payment, and also come with reasonable rates of interest.


Do you want to get the solar lease?

While “free solar panels” (otherwise called solar lease) seem like a fantastic deal, there are a few situations where it is the most effective option to go solar. The only situation where it makes sense to lease solar panels is when you aren’t eligible for federal tax credits or don’t meet the requirements for the solar loan.

The most effective way to finance solar when you’re not able to pay to make a purchase cash-on-cash is through the solar loan. It offers all the advantages from installing solar, including electricity bill savings, and also powering homes with energy from renewable sources as well as not having to think about all the initial expenses.

Before you decide to sign a solar lease it is recommended to obtain solar quotes from several nearby solar contractors. They can assist you in getting the most affordable price for your solar system , and will give you an idea of whether the solar lease might be able to work for your home.



  • Solar leases are a financing option for homeowners who doesn’t have the solar panels installed on their property, but makes a monthly payment to a solar business as a payment for energy that solar panels generate.
  • The homeowner is able to utilize all the power that the solar panels generate, which lowers their energy bill by the agreement known as net metering.
  • The monthly lease payment is usually less than the amount the homeowner’s electricity bill was before installing solar panels.
  • Although solar leases permit you to eliminate the upfront cost of installing solar panels but you will pay a lower savings than if bought these solar panels.
  • Most of the time the only reason it is logical to take a solar lease rather than buying solar panels is when you’re not eligible for federal tax credits.



Do I Have The Ability To Upgrade My Roof With A Solar Panel Leasing?

The majority of solar leases include conditions that pertain to the issue of repairing and remodeling jobs done on the roof of the house in particular when they are near the solar system. When you’re planning to undertake one of these things it is necessary to contact the solar lease provider to obtain permission to work within the system and determine the requirements for the task. They could even assign an administrator to inspect the system.

What Happens At The End Of The Lease The Lease Term?

The solar panel lease contract leasing is between 20 and 25 years that is about exactly the same as the lifetime of solar panels. Once the lease has expired you have the option to sign a new solar panel leasing agreement or purchase a PV array, or simply remove the solar panels, and then consume energy from the grid.

What Happens If The Owner For The Solar Leasing Dies?

In the event that the homeowner, or anyone else who was the person who signed the contract for solar lease passes away the lease contract will automatically be transferred to the those who inherit the house. In the event that you are inheriting a house and want to opt-out on the leasing agreement, you need contact the leaser in order to inquire about the cancellation clauses for the lease as well as the agreement that comes with the lease.

Disadvantages Of Solar Energy

With the cost of electricity increasing by 3% to 5 per year, you might be thinking about alternatives to energy sources, like solar. However, before you decide to put up a solar system at your home, a few important disadvantages of solar energy must be considered.

Solar power has the most expensive initial cost of the other sources of renewable power, it is easy to believe it to be excellent. However, in reality, solar panel panels are not efficient.

If you’re in a desirable area, you’ll be able to achieve an average of 22% conversion that is based on the highest as well as most costly technology.

Additionally, there is the risk that solar panels could be damaged through storms. In addition to the expense of replacing solar panels, damaged ones must be handled and removed correctly due to the harmful chemicals used.

This article will highlight the primary negatives of the solar energy industry, which should be considered before deciding which option is better to invest in solar.

What are the solar energy disadvantages (And for the Environment)?

Solar Energy

Although there are numerous benefits to solar energy, however, there are also some drawbacks since the technology is evolving. It’s currently very cost-effective to put up solar panels as well as related products.

Solar panels need plenty of space. solar energy is influenced by environmental conditions (e.g. the sun, the weather, and the climate).

  • Location and Sunlight Availability
  • Solar Panels take up huge amounts of space
  • The Sun doesn’t always appear
  • Solar Energy is Inefficient
  • There is a missed pollutant and Environmental Impact
  • High-priced Energy Storage
  • The High Cost of Initial Purchase
  • Solar Panels could cause damage to your roof

Location and Sunlight Availability

Latitude is among the primary factors in determining the effectiveness of solar energy. Different locations receive the same quantity of sunshine, and the effectiveness of solar energy dipping significantly the further away from the Equator.

The residents of countries such as Canada as well as Russia are at a disadvantage about solar radiation. But, in places such as Hawaii where they experience an average of 277 days a year of clouds and rain and their position towards the equator doesn’t matter since they do not have enough sunlight that isn’t clouded to reach the earth.

The solar efficiency can also be determined by season. In summer, you can generate more power than you’ll need since the earth’s tilt is such that it’s closer to your place. When it’s winter, the tilt of the Earth makes your place further away from the sun, that you aren’t able to produce enough power to meet your needs.

As with everything else stored in sunlight, solar panels can be damaged by ultra-violet radiation. Things like hail, wind snow, dirt, and temperature variations are major dangers to solar panels.

Installation Area

For those who are looking to set up solar panels the space for installation isn’t likely to be much of an issue, particularly when the majority of the time they are placed in the roofing. But, large businesses that plan to generate large amounts of power will require a large installation area to supply power regularly.

The biggest solar array can be found in Spain and covers around 173 acres. It provides electricity for nearly 12,000 homes. This is 173 acres of land that can’t be used for any other purpose other than for animals that graze there.


One of the disadvantages of solar energy is that it depends on sunlight the renewable energy source. Electricity cannot be produced at night, which requires you to either store the excess energy generated in the daytime or connect to an alternative source of power, such as the local grid. This means you’ll be required to pay more on top of the cost of solar panels.

Storms and clouds can also not excess energy output that you can create because they block light rays that could have been absorbed from the solar panels.


Based on researchers from the Qualitative Reasoning Group with Northwestern University the majority of solar panels installed in homes convert just 14% of their power source into electricity. Even the best-performing solar panels transform 22 percent of the solar energy into electricity.

By the Second law of thermodynamics, solar cells are not able to attain 100% efficiency. The theoretical maximum efficiency is 85 percent, which is using mirrors and motors to track the sun.

In a solar system that doesn’t track the sun’s position, the theoretical maximum efficiency is just 55 percent. This is also true for systems that follow the sun during cloudy days.

Pollution & Environmental Impact

The environmental effects of solar power include water and land use as well as the destruction of habitats, pollution, and the use of extremely dangerous materials in the production process.

Looking back at the location of the installation, the solar fields’ land use could be enormous and, unlike wind power-sharing land for agriculture, purposes are not an alternative. Solar power can also impact the use of land when it comes to mining and the production of the materials required to make photovoltaics.

One of the components found in solar panels is lead and cadmium which are extremely poisonous metals. There are several other toxic and hazardous materials used in the production of solar panels including gallium arsenide, copper-indium-gallium-diselenide, hydrochloric acid, sulfuric acid, nitric acid, and hydrogen fluoride, 1,1,1-trichloroethane, and acetone.

Within the United States, manufacturers are obliged to ensure that high-value substances are recycled instead of getting rid of them. In other countries like China, Malaysia, the Philippines, and Taiwan where more than half of the photovoltaics produced are made the harmful materials are being disposed of recklessly in fields, which pollutes the water, air, and soil.

Expensive Energy Storage

Energy Storage
Energy Storage

A majority of people consider the storage of large quantities of electrical power as the most significant obstacle to producing solar power on an industrial scale. The battery storage systems that are available for storing solar energy systems in the form of electrical energy are extremely expensive.

Tesla is the company that designed its Powerwall battery to save solar energy to be used later. But, with a 14kWh battery costing approximately $7,100 after installation and maintenance, these batteries are expensive.

If you were to have a day’s worth of backup power for a home with four bedrooms that would require three Tesla batteries, which would cost the staggering sum of $18,300.

The High Initial Cost

The high upfront cost is among the major disadvantages of solar panel systems. As of January 20, 2022, the cost of solar power in the US is around $3.00 for each watt. A 6 kW solar panel would cost approximately $18,000, on average, even before the federal tax credit is used.

The price of a solar array is dependent on the state you live in, and also on the incentives, you are eligible for.

There are fortunately loans for solar options to choose from. In many cases, you could qualify for a no-down solar loan that permits you to reduce your electric bills and reap the benefits of having the solar panel system.

Solar Panels could damage your roof

We all wish to use less electricity, even when we’re not making use of it. Solar panels are a great option to generate electricity, but they could cause damage to your roof.

Incorrect installation of solar panels can result in holes appearing on the roof, which could cause water leakage and severe damage to both the exterior as well as the interior of your house.

To prevent this from happening, make sure that you do your research thoroughly on the companies that install solar panels and make sure that they have a good reputation.

Solar Energy
Solar Panels could damage your roof

Solar panels require support to ensure they are securely installed, because of how heavy they are. If your roof isn’t robust or has weak points they may cause the roof to split or “flatten” in time because of the weight.

It is recommended that a thorough evaluation is carried out on the structural integrity of your roof, to verify that the roof can stand the load that the panel can support.

When the panel is set at an angle steeper than the rest of the roof that could make them sway in time, destroying the roof. When the roof panels sit high or too low on the roof, problems could develop in the Attic or hinder gutters from functioning correctly.

The potential for these issues could invalidate any warranty on your roof currently in force. It is crucial to speak with the solar company or roofing company to ensure that the installation of solar panels would not disrupt the coverage.

Although solar energy is regarded as renewable and inexhaustible, However, the method that we currently make use of it has numerous disadvantages, from being expensive to inefficient. But solar technology is at the beginning of its development, and many good ideas are already starting to emerge.

For instance, research into energy storage issues has led to two different ways that could be utilized to store electricity in the future.

In search of inspiration from existing solar energy technology scientists are creating flow batteries using small organic molecules that aid in helping the rhubarb plants store energy known as quinones, instead of the highly toxic and costly metal vanadium particles.

Researchers believe this technology will bring the current cost down from $0.02 per kilowatt-hour to $0.0025 per Kilowatt-hour.

The second technique, which is very clever, utilizes the solar panels produce methanol from carbon dioxide, instead of electricity. The idea is to use the methanol to generate fuel, then transform it into carbon dioxide, which would then be recovered and stored.

The aim is to cut down greenhouse gas emissions through recycling instead of letting them escape into the atmosphere. While the power that solar panels generate is emission-free,  it is important to note that there is some pollution associated with the manufacturing of solar panel system.

One thing is certain but. Energy from solar (for things that aren’t simple outdoor solar lighting is still much to be done before it is cost-effective efficient, reliable, and sustainable.

Tesla’s brand name recognition is also a big help. People know Tesla so they just go straight to it. Their order process is completely online and they only offer 4 standard system sizes, which eliminates many of the overhead costs associated with other solar companies.

Tesla is a large company so they are able to afford to undercharge panels and still make a little profit at the end of the deal.

Tesla’s solar financing

Although Tesla solar panels may seem more affordable than its competitors, not everyone has thousands of dollars to spend in cash. Tesla gives homeowners the option to directly take out a loan through Tesla.

Tesla solar loan

Tesla’s solar loan works like any other regular solar loan. You can take out a loan from Tesla and pay monthly repayments to them for a specific term. You are the owner of Tesla’s loan and receive the solar tax credit as well as other solar incentives like SRECs.

Below is a table that shows the monthly estimated payments for Tesla’s various solar system sizes.

Tesla solar panel systems: Features

In the past, Tesla used Hanwha Q CELLS’ Peak Duo Black solar cells, specifically the Q.Peak Duo Blk–G6+ modules to power their solar panel installations. Tesla announced in 2021 that they would be switching to their own solar panels.

There are two types of Tesla solar panels available: the H Series or the S Series. Let’s look at the performance of these panels.

Tesla and their loyal fans love to claim that Tesla’s panels have a higher power rating than any other residential solar panels available. The truth is that Tesla’s panels are not as impressive as they are commercially sized. The S Series panels actually have a larger footprint than most commercial solar panels.

The panels of Tesla have more surface, which means that more solar cells can fit into the frame. This increases the power rating. This is not due to Tesla using some kind of breakthrough technology. You could use the same solar cells in standard residential sizes to get the same output as other panels on the market.

We are not denying that the Tesla panels have great technical specifications. They are compatible with popular Tier1 solar brands and have a temperature coefficient that is close to the real world.


Three warranties come with a Tesla solar panel system:

  • A product warranty
  • A performance guarantee
  • A 10-year comprehensive warranty


Warranty on product

The product warranty on Tesla panels guarantees that the panels will not be damaged in any way for 25 years. This product warranty is far superior to the industry standard of 12 year.

Performance warranty

Solar panels that are older don’t produce the same amount of electricity as they were when they were new. The performance warranties describe how solar panels will age.

The warranty from Tesla states that the panels will run at minimum 98% of their original rated power after a year of usage. The panels’ power capacity will not decrease by more than 0.54 percent over the remaining 24 year warranty period.

This is in line with industry standards. Most panels have an annual decay rate of 0.50%. Tesla’s is slightly higher than this, which isn’t necessarily a bad thing. The lower the degradation rate, the better. Tesla panels may degrade slightly faster than other solar panels, but it shouldn’t be considered a decision-making issue when you are considering Tesla solar panels.

Be aware that Tesla offers a variety of warranty terms. This is the official warranty document that Tesla provides on their website. However, they do not provide a separate set of performance warranties on the H Series panel data sheet. They also have a statement which includes another performance warranty.

10-year comprehensive warranty

The comprehensive warranty covers all aspects of your Tesla solar system. This includes any Powerwalls that you install, the Tesla solar Inverter, roof mounting, leaks, and any other devices. A comprehensive warranty is nice because you will only need to deal with one company in the event of an issue with your equipment.

For example, a regular solar panel system would have an inverter from a different company. You’d need to keep track and be aware of several different warranties. A comprehensive warranty from one company like Tesla can save you headaches down the road.

Although the details of Tesla’s comprehensive warranty don’t appear on the website they are in the purchase agreement that you sign when you order the panels.

What panels will Tesla install on your rooftop?

They don’t provide any information on the specifics of their panels, so it’s not clear what size or series Tesla will install on your roof. Based on here it appears that the standard Tesla panel is 400 watts. Despite this, there are many places on their website that are out-of-date. You won’t be able to tell until you order.

How do Tesla solar panels function?

The three main components of the Tesla solar energy system are:

  • Solar panels
  • Tesla’s latest solar inverter
  • Tesla Gateway Monitoring System

The solar panels convert sunlight into electricity. The electricity is then converted to AC electricity by the Tesla solar inverter. You save money by using the electricity generated by your solar panels.

Solar panels produce the most electricity during the middle of the afternoon, when the sun is at its highest. If you have one, any energy your solar panels produce will be sent to your Tesla Powerwall.

Depending on the system configuration, you may take electricity from either your grid or your battery at night if your home’s energy consumption is greater than your panels are producing. You can monitor the progress of your solar power system with the Tesla app.

Are you looking to install a Tesla Powerwall using Tesla solar panels?

Tesla has been unsure for the past year whether they need a Tesla Powerwall to power their solar panel installations. Tesla no longer requires a Powerwall to use their Tesla solar panels as of October 2021.

You can add $11,000 to your Tesla solar panel installation costs if you wish to add energy storage.

What’s the difference between Tesla’s solar panel roof and Tesla’s solar panels?

Tesla solar panels are similar to the ones you see on rooftops. These panels are placed on top of your roof and produce electricity for your home. Tesla’s Solar Shingles look just like traditional roofing materials.

Tesla solar shingles need a new roof to be installed. The solar roof tiles will not stand out from your other shingles. Tesla makes their solar shingles at their Buffalo, New York gigafactory, rather than using traditional rooftop solar panels. Learn more about Tesla’s solar roof and conventional solar panels .

Tesla’s customer service is lacking

You will probably get the best price for solar with Tesla. However, the price of solar does not include the cost of a long-term relationship with your solar installer. This seems to be the area where Tesla saves money.

Tesla is known for their poor customer service. Judging by the customer reviews on the web. They are a huge company so they won’t be able to provide the kind of personalized service you require when you go solar.

Customers of Tesla have complained that it is difficult to contact them if their system has a problem. It can also take longer to get someone to inspect the issue. This could lead to you losing a significant amount of money.

Your solar panels won’t produce enough energy to power your home. This will result in a lower electric bill. You will lose more money the longer it takes to repair your system.

Are Tesla solar panels really worth it?

At first glance, a Tesla solar panel installation seems like a no-brainer. The ordering process is simple and the panels are of high quality at an extremely low price. We can only say that it is possible to get solar panels at a fraction of the price if it sounds too good to be true.

Communication between you and your solar company are key to success in solar. They will be your main contact for at least 25 years. Tesla’s track record suggests that they may not be the right ones to trust if things go wrong. The potential headaches that could result from a solar installation will not be worth the cost savings.

Before you make the decision to go solar with Tesla, we recommend that you get quotes from several local installers. Although the prices of local installers will be more expensive than Tesla’s, they offer a better value for long-term relationships.

Tesla Powerwall Alternatives

In 2020, solar energy was the cheapest source of electricity in several countries. As a result, there is a rise in the number of people installing solar panels. Self-consumption is increasing and consumers are becoming energy producers. Tesla Powerwall is one of the most adored solar batteries available on the market.

This year, Tesla opened the door for self-consumption of energy by introducing the Powerwall an energy storage device for homes that was the initial home (ESS). Plug-and-play technology that store excess solar energy generated from solar panel system in rechargeable lithium battery that can be utilized at any time within your home.

However, Tesla isn’t the only one offering ESS. So, we’ve picked the top Tesla Powerwall alternatives for 2022 considering both their cost as well as the technology they offer.

What Is A Tesla Powerwall?

Powerwall is the commercial name used by Tesla for their domestic energy storage solution – also called an AC battery. It is a wall-mounted box that incorporates:

  • A rechargeable lithium-ion battery system
  • An AC inverter

The Powerwall can store AC electricity from a solar inverter and deliver AC electricity (110V/220V, 60Hz) back to your household electrical system or to the electricity grid.

Is It Worth Buying A Powerwall In 2022?

We are convinced is Powerwall is an excellent option to add to your home’s electric system. We can see three distinct advantages of this storage system:

Is It Worth Buying A Powerwall
  • A reliable source of backup power that acts as a backup power source in the event of a power outage (13.5kWh)
  • Allows self-consumption of solar energy for full or partial off-grid homes.
  • Controlling energy consumption on a time-based basis (self-consumption during peak times of electricity).

In the case of storage for energy when it comes to energy storage, you should consider the levelized cost of Storage (LCOS) as the most precise cost estimate for your system. It is based on the total amount of charge/discharge cycles during its life. This figure in dollars per kWh is used to assess the absolute costs of various storage systems for energy.

The Tesla Powerwall 2 was released in 2016 the initial cost is broken down into the following categories:

  • 6500 dollars (unit cost)
  • 3,500 USD (installation cost)

A total of 10,000 USD in upfront costs. With the 37.8 MWh guaranteed total time, the LCOS of the Powerwall 2 is 0.26 USD/kWh.

It’s still more expensive over the median US electricity price of 0.13 USD/kWh. However, it’s less than the cost of electric power from Hawaii (0.33 USD/kWh).

How can you compare your batteries at home

When looking at the various options for batteries for your home There are several key data things to be aware of: size, warranty conditions, and cost. Although these aren’t the only variables to take into consideration when choosing a solar battery system, they’re an excellent starting point and will aid you in understanding the benefits and costs that come with each choice.


When we discuss the size of solar batteries we’re talking about two parameters: usable capacity and power. Its power (measured in kilowatts or kW) is the amount of power that can be produced in a single moment and the usable capacity (measured in kilowatt-hours which are also known as kWh) is the measure of the total amount of energy stored in the battery fully charged.

It is possible to think of these crucial size measurements as the flow of water through the pipe. Usable energy capacity refers to the amount of water that is available to move through the pipe. power refers to the size that the pipe. Larger pipes permit more water to flow through at a time and drain the total amount of water stored.

A battery that has large power will be able to supply greater power in a single time but it also spins through its energy capacity quicker as well.

(To increase the complicated of the equation) there are usually two power indicators on the specifications sheets of battery manufacturers which are: startup and continuous which is also known as instantaneous power.

We’ve put together a useful article that compares both and, for now, it’s sufficient to know that continuous power refers to how your battery’s capacity can be measured continuously over hours and startup power refers to the power surge the battery can provide for a short period or even a couple of seconds to start large appliances such as an HVAC or a sump pump.)

The battery’s power will determine what appliances you can use it with simultaneously and the usable capacity is the amount of time these appliances can remain running using the batteries.

Batteries with a greater power rating can run larger appliances that consume energy or many appliances simultaneously in comparison to batteries that have larger usable capacity can conserve more energy, and can keep appliances running for longer durations of time without the need to recharge.


Batteries generally have a capacity guarantee which ensures that a specific proportion of the battery’s original capacity will last for an agreed-upon duration (often 10 years.) Additionally, certain batteries come with two types of warranties one being the throughput warranty (usually measured in megawatt-hours, (also known as MWh)) as well as the guarantee for cycles (measured by the full charge/discharge cycles).

Throughput warranties set the amount of energy you can use for your battery in the warranty time frame while remaining within the range of the guaranteed capacity of the energy warranty. Cycle warranties are a different way to determine the duration of a warranty – they provide the frequency at which you can charge and discharge your battery before when the warranty capacity expires.


Cost is another aspect to take into consideration when looking at the options for your home battery. Similar to comparing the prices of solar panels, there is an underlying difference in the price of the device itself and the price of a complete installation.

In addition, solar battery installation costs are contingent on the features of the property you live in – for instance the electrical panel configuration and the wiring you have in place could mean an increase or decrease in work for the installation team. Therefore, the exact “price” for installing a solar battery will differ for each.


Final Thoughts

Tesla was the first to introduce the domestic market for Energy Storage Solutions (ESS) through the Powerwall. Since then, many companies that offer similar products have come up.

We’re in a transitional period about the production of energy – transitioning from fossil-fuels production to renewable sources.

Furthermore, we are shifting from a centralized approach to making energy.

Through the combination solar panels together with ESS systems, anybody can become an electricity producer that can be self-consumed or inserted into the electric grid.

ESS Systems are getting more affordable due to the decrease in the price of LFP batteries. Furthermore to that, as the industry develops hydrogen technology energy efficiency and reliability will grow which will make them important for every household in the next few years.

How Long Does A Solar Panel Installation Take?

One of the primary homeowner’s questions when contemplating installing solar home panels , is “how long will the installation take?”. It’s true that the actual installation process can be as quick than six hours. However, going solar is comprised of more than simply having contractors set up in your roofing. There are additional things to consider in determining the best time and date to finish your solar installation.

We’ll guide you through the process of installing solar and help you determine the length of time it could take to complete the installation for your home.

The solar installation timeline at a glance

  • The entire solar installation process can take from two to six months for completion.
  • Typically, contractors can install a solar system for homes in just 6 hours.
  • The longest portion of the installation procedure is waiting for approval of the permit and is likely to take nearly two months to finish.
  • Once the system is in place after installation, you must wait one to six weeks for your municipality and utility to examine and accept the installation.
  • In the meantime, waiting in the meantime for installation completed is worth the wait since the system will reward you with hundreds of dollars of electrical cost savings over the next 25 years.


Solar panel installation process timeline

Installation is only one part of the puzzle to changing to solar. Eight crucial steps can ensure that the whole process can take anywhere between 2 to 6 months in the average.

Selecting an installer for solar

Time: One day up to two weeks

Picking a solar company is the most important aspect of your solar journey. The company you choose will determine not just the cost of the installation, but the quality of the installation and the timeline too!

It is important to ensure that you’re choosing the most trustworthy company that has been in operation for at least five years, has at least a NABCEP accredited installer and is a reputable one with positive feedback from clients. The process can take less than an hour however, it’s crucial to make the effort to look up several installers that which you are comfortable with, but obtain and review the quotes they offer. It is not advisable to skimp when it comes to selecting the best company.

At least three estimates will increase the likelihood of getting the best quality installation and the best price. The easiest method to locate reliable solar firms in your local area is using our cutting-edge solar calculator that lets you view your solar savings potential and will help you start gathering estimates.

Site evaluation

Time 1 week

Once you have chosen the solar provider and they’ll have to conduct an inspection of your property to determine if the roof you have is appropriate for solar installation. A representative from the installation company will visit your home and inspect the area to assess the state and shade, dimensions, and orientation that your roofing is facing. They’ll also ensure that your roof is able to handle the load of solar panels. They’ll also examine the electrical panel to determine what needs to be done. improvements.

The site evaluation is less than a day, one or two hours maximum however, we provide an estimated timeframe of one week in order to take time for scheduling.

System design

Time 2-to-3 weeks

If you’ve determined whether your roofing is suitable to be solar-powered An engineer will then begin the design of the solar system. Your usage of electricity, roofing characteristics as well as local building code regulations and utility requirements are all considered when making the design.

The process of design could take between about two and three weeks, on average, however it could be longer if the roof is more complicated. However, the initial planning phase for complex systems will likely not be more than four weeks finish.

Requesting building and solar permits

Time 2-7 weeks

Installing solar panels is a building project which is why you should get all the required permits before you begin installing. Unfortunately, the process of obtaining permits will likely to be the longest component of solar installation. The specific permits required vary between towns. Certain towns have solar-specific permits, while other towns have different electrical and building permits that have to be acquired.

Based on the type of permits required and the permit procedures implemented in your locality It can take up to two weeks for approval, or nearly two months. We all know that waiting for this long to get permits is irritating. However, the good thing is that your solar installer is the one responsible for all the paperwork , so you don’t need to fret about it.

Making arrangements for equipment, and scheduling the installation

Time 1 – 4 weeks

Once your permits have been granted, your company is able to begin to make preparations to put in your system. Certain installers have the necessary equipment they need to get going with your project as soon as possible. There is no need to wait for the equipment to be shipped, but you may need wait until they find time for the installation. This is the reason we offer this stage one week at a minimum.

If your installer isn’t carrying items on hand and it can take several weeks for all the items they require to be delivered, particularly in light of the ongoing issues in the solar sector’s supply chain problems.

Attention buyers of batteries: You may have to wait longer when you pair an array of solar panels to batteries stored in solar panels. Batteries are extremely sought-after and it's not easy to locate one on time. Certain installers might have them on hand but don't be too surprised by the fact that the battery will add significantly to the wait time.


Time From 6-hours to three days

As we mentioned earlier, installing solar panels will be the fastest phase of the procedure. For the majority of homes, it will take about six hours to complete!

Similar to the structure of the solar system. The more complicated it is, the longer time it’ll require to complete. In the vast majority, your solar installation shouldn’t take more than three days unless unexpected problems occur during the installation. However, the most likely scenarios are few and far and few.

City inspection

Time Between 1 and 2 weeks

The installation might be completed however this doesn’t mean you’re ready to produce electricity right now. It’s important to get a few confirmations before you’re operational.

In the beginning, an inspector from the local area will be on site to verify that the system is installed correctly and meets the proper building regulations. This is a security step, so that any problems are identified prior to the system goes into operation.

Similar to the site inspection it will be a couple of hours at most and it may take up to a week to make the appointment.

Interconnection with utilities and the permission to operate

Time between 2-6 weeks

Also, you’ll need wait for approval to use the utility company before you begin to use those solar panels. It shouldn’t come as a unexpected that waiting on approval from the utility may take a long time.

Typically the utility will go to your property, put in an electric meters that are able to properly communicate the solar energy produced and perform a brief check. After this is completed your interconnection contract will receive the seal of approval, and you’re now able to start powering your home using solar power!

Final Thoughts


Installing solar panels is worth the long wait

We know that the six-month period is long. However, as the saying says, good things will happen to those who sit. Even if it takes several months to get the installation finished and completed, it takes only 9 years (or maybe less!) for solar panels to be able to pay for them. In the end, you’ll have 15 years of totally free electric power. Additionally, it’s beneficial for the environment – who would not want to be a part of this?

If you’re contemplating whether you’d like to put the time, money and effort in the solar industry then you can use our solar panel calculator for free to determine the amount of solar panels that you’ll require and what incentives are offered and how much you could save, and what the payback time will be.


Still, how long does it really take to switch to solar power?

If you take into consideration everything you must do in order to put solar panels on your roof, it is possible to take anywhere from two months or more than six months. Remember that this timeline is only an estimateand could differ greatly based on the specifics of your situation. The solar company you choose to work with will be able to provide you with the information of what the normal timeline is for your region.

Tesla Powerwall: Is It The Most Efficient Solar Battery?

Solar storage was initially a topic about the future distant however, Elon Musk’s Tesla Powerwall battery system changed the conversation to one about the present. There have been a number of variations that have been made of Tesla Powerwall, including its current version, which is called the “Powerwall+”.

The Powerwall is, without doubt, an excellent home energy storage system. It is packed with amazing features , and is available at a fair cost. However, is it the most efficient solar battery for your home to use with solar panels? The answer could be surprising to you.

Important lessons to learn from the Tesla Powerwall

  • The Tesla Powerwall costs $11,000 with installation included when purchased through Tesla.
  • Tesla Powerwalls aren’t offered for sale on an individual basis through Tesla however, the standalone Powerwall can be purchased through an installer who is Tesla-certified.
  • The Tesla Powerwall comes with the capacity to store 13.5 milliwatts. It also has a constant output of 9.6 kW and three modes of operation including Solar Self-Consumption and Backup Only along with Time-Based Mode.
  • The Powerwall is a fantastic battery However, there are many other options available to offer superior value and service, such as LG Chem Prime. LG Chem Prime.

How much will this Tesla Powerwall cost in 2022?

In February 2022. The total expense of installing a Tesla Powerwall+ battery system is $11,000..

Despite Tesla boasting they would ensure that Tesla Powerwall costs would fall by half within about three years’ time, the reality is that we’ve observed the cost of the Powerwall rise three times, before finally reaching the current cost.

In addition, Tesla no longer sells their Powerwalls by themselves, meaning the amount you’ll need to pay will include the cost of a Powerwall as well as the cost of the new solar panel If you’d like to purchase to purchase your Powerwall straight from Tesla. It is possible to purchase the Powerwall by itself from local businesses, however the disadvantage is that purchasing the Powerwall from an outside source other than Tesla isn’t a guarantee to receive the $11,000 cost.

Tesla might also require upgrading your electric panel prior to when you install the Powerwall and this could increase the cost by $2,500 on the cost of your installation (a expense that Tesla doesn’t even mention in their initial cost estimates).

Is Tesla Powerwall Tesla Powerwall qualify for any rebates or incentives?

Yes it is true that the Tesla Powerwall does qualify for the incentives for battery storage that are available within the U.S.

The most significant reward comes from an incentive called the Federal solar tax credit which can reduce the price of the Powerwall setup by about 26% provided it’s connected to solar panels.

In addition to the tax credits offered by federal law, certain states and utilities provide additional incentives and rebates. In certain instances, these rebates, including the California incentives for SGIP as well as Green Mountain Power’s Bring Your Own Device Program in Vermont will cover nearly 90 percent of the cost of installing the Powerwall.

The key characteristics of the Tesla Powerwall

The Tesla Powerwall comes with some impressive specifications, and one of the more amazing innovative monitoring and management capabilities in the solar battery industry.

Lifespan and Warranty

The powerwall’s life span is fairly normal for lithium ion batteries. They will be operating with 70% initial capacity within 10 years. The operating mode you select will determine the length of time your Powerwall battery lasts.

The details of how you use your battery affects the battery’s life are detailed by the Tesla’s warranties.


The capacity of a battery tells you the amount of electricity it is able to store. The greater capacity, the more the battery will power your home. With the capacity to store 13.5 Kilowatt-hours (kWh) of power the Powerwall is able to store enough power to provide about half of the typical American household’s regular energy consumption.

A single charge of the Powerwall is likely to power all the necessities within your home, such as your fridge and WiFi, a few outlets, and even a couple of lights for around 24 hours.

Continuous power rating

The introduction of Powerwall+ brought one major modification: a greater power rating. The power rating continuously of a battery will tell you what number of appliances it is able to run.

Powerwall batteries hooked up to the grid provide 7.6 kW of power even when there is sun and 5.6 5 kW without sun. This means that one Powerwall can power electric outlets, lights, and 120-volt appliances, like the fridge in your home. If you’re looking to power large appliances, like cooling systems, such as air conditioners, you’ll require additional Powerwalls.

The unique thing with the Powerwall is the fact that it can release more power when it’s off grid, with a range of 7 kW to 9.6 kW, dependent on the weather conditions. Also in the event that the Powerwall isn’t linked to the grid for instance during power outages it is able to power a number of appliances within your home.

Peak power rating

Apart from being rated for continuous power capacity, batteries have the capacity to deliver peak power that is the highest quantity of power a battery can produce within a relatively short amount of duration (usually around 10-seconds). The peak power rating evaluates the battery’s capability to withstand short power surges, such as when appliances require more power to power up.

There isn’t any peak power rating available for the Powerwall when linked to grid. However, when operating without grid connection, the power peak can range from 10 kW up to an impressive 22 kW if there is sun.

The numbers are significantly more than the industry standard for peak power rating which is typically approximately 7 kW of output. But, you’ll get to the full potential of your solar system if you possess a minimum of a 12 kW solar array in order to have enough power to get to the output.

Operating modes

The Powerwall also comes with three modes of operation that are standard for the Powerwall:

  • Solar Self-Consumption
  • Time-Based Control
  • Backup Power

These modes let you select when and how you discharge and store energy into your battery. In the Solar Self-Consumption mode, you can provide your home with solar energy, even when it doesn’t shine by storing solar energy to use in the future.

In Backup Power mode, you can decide to let your Powerwall only serve as an emergency backup battery in the event of a blackout.

Time-Based Control is useful when your utility is using time-of-use (TOU) rates, which means that your utility charges different electricity rates based on the time of the day. If your Powerwall is operating in the Time-Based Control mode it will charge the battery whenever electricity is the most affordable and discharge the battery when electricity costs are at their highest and will allow you to reduce the cost of your utility bills.


Tesla Powerwall Tesla Powerwall is an AC-coupled battery, which means that the battery has its own built-in storage unit (which is essentially an inverter integrated into the battery). The primary benefit that AC-coupled batteries have is the fact that they’re simple to connect to solar panels already in use. Additionally, in the event that something is wrong with your solar inverter battery will function as normal in the opposite direction.

But AC-coupled battery systems are less efficient than DC-batteries. Also, the addition of hardware means that there are more components which could fail.

Find out more about the distinctions among AC battery and DC-coupled ones in our comparison guide.

How long will it take to purchase an Tesla Powerwall?

Tesla Powerwalls come with an significant waiting time due to the fact that the demands for solar cells is large as more and more homeowners seek access to secure backup power. Tesla’s production capacity simply cannot keep up with. It was discovered the fact that Tesla has an influx of 80,000 Powerwall orders which have yet to be completed.

You can buy Powerwalls Powerwall through Tesla directly through an investment in a solar roofing system for solar panels. You can also purchase a Powerwall through an Tesla Partner Installer. Customers who purchase the Powerwall units directly through Tesla will have shorter waiting times generally several months. Customers who purchase an Powerwall via Tesla installers have had to wait for nearly a year before getting their batteries installed. It seems like Tesla has placed a priority on fulfilling the direct orders first and abandoning their installers to empty.

So, if you’re searching for a new battery to be added to your installed solar system, and you do not want to wait for an entire year to have an solar battery You’ll need an alternative to a Powerwall replacement.

Do you require solar panels to operate a Powerwall?

Tesla Powerwalls are able to be operated without solar panels and simply draw electricity from the grid, which can serve as backup power in case of grid failure. The problem is that Tesla does not sell Powerwalls on their own, so for you to purchase an Powerwall straight from Tesla you will need to purchase an Tesla solar panels as well as a the solar roofing system.

If you’re looking to purchase a Powerwall without paying to install a total solar power system it isn’t possible to purchase it directly through Tesla. Instead, you’ll need purchase the Powerwall to sell it on your own through an authorized Tesla Powerwall installer.

As we’ve said before that using an Tesla partner usually means more wait times, and it’s not easy to locate an installation that will set up a battery it’s own without solar since it’s not as lucrative to the contractor. It’s possible to do it but it’s difficult to find one and you’ll need to be prepared for a long waiting time.

In order to obtain an Powerwall directly from Tesla quickly it is necessary to purchase an electric system on Tesla’s website. Tesla web site.

Does this Tesla Powerwall worth it?

Our opinion is that the Powerwall is an excellent battery. It comes with advanced features and impressive technical specifications for reasonable prices.

What is it? Is the Powerwall worth the price? In truth, no at all. The battery we have put on top of our checklist is called the LG Chem Prime due to its power-capacity in terms of operating modes, as well as its low price.

Unfortunately the decision of Tesla to sell Powerwalls with the latest solar panels makes it more difficult for home owners to obtain one. This is an enormous disappointment for a number of reasons.

First, those who have solar panels but want to add a battery not get an Powerwall directly from Tesla however, they will have to find an authorized installer willing to offer the Powerwall to homeowners. In addition, they could need to endure long wait times.

In addition with regards to solar panels, Tesla is notorious for being known for poor after-sales support. Therefore, for homeowners who are interested in to purchase a Tesla Powerwall and want to install it, they are at the risk of having to deal the poor customer service Tesla is well-known for. This isn’t just a problem when you’re having the system set up, it’s something you’ll need to confront throughout the lifetime of your solar panels for a total of 25 years!

In addition the fact that Tesla fulfilling their own orders prior to taking on projects which their installers have entered into contracts, it’s hard to tell which one you’ll get. Powerwall from a different company than Tesla. Tesla has changed contracts signed previously for their solar roofs however there’s no chance of it happening when it comes to their Powerwalls.

Final Thoughts


With that said, if you do not already have solar, you must be willing to take the risk of receiving poor customer service for the next 25 years you’ve got Tesla panels up on the roof of your home, or you are happy with the possibility of months or even years of waiting periods to get an electric battery or replaced, then the Tesla Powerwall is the right choice to you.

If this doesn’t suffice, you can call your local solar installation company and ask them what solar batteries they would recommend and if they’ve got Powerwalls that they can install. The easiest method to find installers who can help you connect a solar system with storage for the most affordable price within your region is to use our solar calculator on the right.

President Biden Adopts Executive Actions To Increase Solar Energy What Does This Impact Homeowners?

Takes executive action in order to increase solar
President Biden Adopts Executive Actions

President Biden Adopts Executive Actions To Increase Solar Energy What Does This Impact Homeowners?

The 6th of June 2022, president Joe Biden announced two executive initiatives to increase both the U.S. solar manufacturing and installation industries. The first was an emergency Declaration of Emergency to address the shortage of solar panels within the United States, which has slowed the progress of many gigawatts (GW) of energy-efficient solar power projects. Another was the invoke under the Defense Production Act to increase the production of solar panels in the United States and other renewable energy technologies.

The Biden Administration is hoping that the two measures will boost U.S. solar manufacturing capacity by 20% over the current level and lead to as much as 100 GW more solar energy generation over 10 years, more than in the event that executive measures were not implemented.

Let’s examine the motives for the President’s actions as well as the long-term and immediate consequences they’ll bring, and the potential impact on the solar market for residential homes.

Key takeaways

  • Vice President Joe Biden took action in June 2022 to boost the number of solar panels across the nation by putting off tariffs on solar panels from other countries which could threaten the U.S. the solar industry.
  • Also, the administration announced President will make use of the Defense Production Act to encourage investment in manufacturing of solar panels in the coming two years.
  • These two steps will boost capacity of solar capacity that will be built by 2022 and set the U.S. on the path towards a stronger manufacturing of solar panels in the coming years.
  • In Biden’s proposal Biden’s plan, Biden’s plan is that the Federal government will be able to purchase up to 10-gigawatts worth of solar power over in the coming 10 years providing producers in the United States more assurance that they can market their products.
  • The Biden Administration’s policies will ensure that the residential solar industry running by allowing U.S.-based producers to continue to import key components for solar panels and also to expand their capacity to manufacture the materials themselves inside the U.S.
  • The prices for solar panels for homes aren’t likely to alter much in the next couple of years because of the shortages in supply and the eventual transition into U.S.-based manufacturing.


What specific steps did the President decide to take and for what reason?

In the issuance of an urgent declaration with an emergency declaration, President Biden ordered his Secretary of Commerce to allow for a period of 24 days “the importation, without the collection of duty and estimated duty… of specific solar modules and solar cells” that originate from the 4 Southeast Asian countries: Cambodia, Malaysia, Thailand, and Vietnam. This was due to the request from U.S. solar module maker Auxin Solar, which asked the Commerce Department to investigate whether solar technology from these countries was being offered by Chinese firms in an effort to get around the existing trade barriers against dumping.

In the event of fears that tariffs could result due to the investigation, many solar companies in the countries that were targeted stopped shipping their products in America. U.S. in the spring of 2022. This had a significant impact on the estimates of solar installations. If tariffs had been put in place this would have led to an increase of 50% on solar power installations throughout the remainder throughout the entire year. With no tariffs for the duration of 24 months, firms will be able to restart their production lines, however it will take some time until the solar industry can catch up, and some projects may remain delayed.

In conjunction in the wake of the Emergency Declaration, Biden announced he will make use of the Defense Production Act (DPA) to help spur the growth of U.S.-based manufacturing of clean energy. This will ensure there is a guarantee that the United States has enough manufacturing capacity to meet the needs of the solar installation business when the time limit of 24 months on the new tariffs comes over.

The decision to make use of the DPA signifies it is expected that federal officials will sign specific multi-part agreements with manufacturers of solar equipment. These contracts, known as “Master Supply Agreements” that will guarantee producers that government agencies will purchase a specific amount of solar panels and insist that the panels be manufactured using a specific proportion of U.S.-sourced products and labor.

In addition to solar-powered equipment In addition to solar equipment, Biden administration has also enacted solar equipment. Biden administration is also called for the DPA to encourage the domestic production of energy-saving and clean technology like the insulation of heat pumps and heating systems, and equipment for the production of green fuel cells and grid infrastructure. In total, Biden’s initiatives are intended to speed up the transition of the nation towards clean energy. But can they?

What effect can these actions have?

The immediate impact of Biden’s executive decisions is the resumption of a number of large-scale solar projects which were put off as they were under investigation Commerce Department investigation loomed. A reputable expert estimates that the investigation was stalled the development of 6 Gw of solar power projects and Biden’s Emergency Declaration would lead to between 2 and 3 the GW of those projects getting their projects back on track.

In 2023, manufacturing facilities of the four countries of the target will be restored fully operational as well as the solar utility pipeline reinstated. Stateside manufacturing will also rise due to the DPA order that promises companies that with federal support to purchase their products when certain conditions are satisfied.

For clarity, the Biden directive does not end the Commerce Department’s investigationbut it has delayed its probable outcomes to 24 years. If the investigation concludes that Chinese firms are evading taxes and chooses to impose additional tariffs on imports coming from the four countries mentioned the tariffs will go into effect by the middle of 2024. U.S. solar manufacturing capacity will need to be in better condition by then.

Prior to Biden’s recent order, industry analysts from Wood Mackenzie predicted an estimate that U.S. would see demand for about 30 gigawatts of solar by 2023, and greater than 50 GW annually until 2030. The majority of solar panels employed in domestic installations originate from outside the United States. Should the Commerce department decides to impose major new tariffs on solar panels imported from abroad producers will probably decide to build new plants within the U.S.

Historical and estimated solar installationsv

In the last quarter of the year 2020 U.S. solar manufacturers produced (and sold) 7.5 GW of solar panels annually. In order to cover the gap in the demand for domestic solar panels in there is a need for U.S. would need to witness at minimum 15GW new production capacity coming into operation by 2024. That’s exactly what Biden’s estimate.

In addition to the demand already in place In addition to the demand already in place, the Biden administration has stated that it expects that the U.S. government will buy at least 10 GW of American made solar panels in the coming 10 years and wants local and state governments to get involved, and estimates that there could be 100 GW demand from government for solar panels in the coming decade.

With the possibility of taxes on imported solar modules and cells as well as the rising demand for domestically-produced solar modules will be enough to attract lots of new investment within U.S.-based production facilities. In the longer term this could result in less expensive prices and more options. But does this mean lower costs to the typical American consumer?

What do these mean for homeowners?

It’s probably not that as much, at the very least for the beginning. The majority of U.S. home solar installations are already using US-made panels made by Qcells, Silfab, Jinko, and other. The manufacturers make modules across the country, and they buy their the solar panels as well as the cells that are used in these modules from the four countries that are part of investigation by the Commerce Department investigation.

The one-year pause on the tariffs is going to mean U.S.-based producers can continue to source materials for solar panels in the way they have always done and can sell their products at roughly the same cost prior to the investigation. However, due to the risk of tariffs looming in the next the next 24 months, these producers will need to adjust to fabricating themselves silicon wafers and solar cells or buying the parts through U.S. manufacturers.

This means that manufacturers in the U.S. will have to hold or raise their prices over the next years as cell and wafer production in the United States grows. In the long run switching to domestic production of components needed for solar panels will provide a variety of advantages for America. U.S. in terms of employment, energy security and corporate earnings, however, cost savings for consumers are not expected.

In addition, considering there is a chance that the Federal solar tax credit is scheduled to be phased down in the coming year and then disappear in 2023. this is the perfect time to get solar panel systems. If you’re thinking of installing solar panels in the future after 2023, and you want they to be affordable, then call your representatives and request for their support of their support for the Build back better agenda that includes provisions to offer new solar financing and also make the tax credit completely refundable.
