Tesla Solar Panels: Are They Worth The Investment? (Review)

You’ve probably heard of Tesla if you’ve ever considered installing solar panels. Their website suggests that going solar with Tesla would be the best way to get a high-tech home and lower your electric bill. But, it might not actually be true.

What’s it like to make the switch from solar with Elon Musk? Are Tesla’s low prices too good to be true

This article will cover everything you need to know to buy Tesla’s solar panels. We’ll discuss the approved financing options and whether buying them is the right choice for you.

Tesla solar panels at a glance:

  • Tesla solar panels are about $2.21/watt before the federal tax credit.
  • Tesla has its own solar panels, ranging in size from 395 W up to 430W.
  • Although Tesla’s performance warranty may be a little lower than industry standards, their product warranty is superior to many other solar panel brands.
  • Although Tesla offers solar at a very affordable price, they are not great at customer service. This is especially important for solar panels that will last 25 years.


How much do Tesla solar panels cost?

Tesla solar panels cost about $2.21 per Watt, including the federal tax credit. The price of Tesla solar panels can vary depending upon where you live. It can range from $2.00 per Watt to $2.51 Per Watt. Tesla’s prices are lower than the average national solar cost of $2.60 per Watt to $3.00 per Watt.

Tesla makes it easy to buy solar panels by offering standard sizes of solar systems: small, medium and large. Below is a table listing the sizes of these systems and their prices:

You can order Tesla solar panels by going to their website. Simply enter your address and Tesla will recommend the size system that is most suitable for you, based on your energy consumption. If you are not satisfied with their recommendations, you can choose from one of their other sizes.

How can Tesla’s solar panels be so cheap?

Tesla’s ease of ordering is one reason they are so affordable. 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.

How the Powerwall Works

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.

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 (an 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 affect the battery’s life are detailed by 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 a 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 a Tesla Partner Installer. Customers who purchase the Powerwall units directly through Tesla will have shorter waiting times generally several months. Customers who purchase a 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
U.S. solar PV installations and forecast, 2010–2030. E = estimated. (Wood Mackenzie) Canary Media/Wood Mackenzie

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.

Does It Make Sense To Have 500-watt Solar Panels In 2022?

Solar Panels
Does It Make Sense To Have 500-watt Solar Panels

Does It Make Sense To Have 500-watt Solar Panels In 2022?

The solar technology is becoming stronger. Seven of the top solar panel manufacturers are now producing 500-watt solar panels.
500 Watts is an extremely impressive output for one solar panel. The standard output of residential solar panels for 2022 is between 350 between 400 and 350 W.

We are aware that 500 W solar panels are massive. Are they more efficient?

In this post, we’ll explain all you should learn about solar panels that produce 500 W as well as if they’re worth it in your own home.

What is a solar panel with 500 watts?

The wattage of a solar panel with 500 watts is calculated under optimal sun and temperatures. A 500W solar panel can produce 2 kilowatts (kWh) of power per day in a place with the normal quantity of sunshine.

As for efficiency, the majority the panels with 500 W that we evaluated have an efficiency of 21% or more.. It is recommended to have twelve 500 W solar panels in order to create a typical home system, which has 6 Kilowatts (kW) from solar power.

For comparison, constructing the equivalent system of 6 kW with the standard modules of 375 W would require 16 panels. To figure out the number of solar panels that you’d require for your home make use of this solar panel calculator here.

Technology that powers 500-watt solar panels.

A variety of ingenuous solar technology is used to attain the solar panel’s rating that is 500W. Two technologies are typically used to create these panels.

Half-cut solar cells

The 500 W solar panels we tested are built using half-cut solar cell technology..

Half-cut solar panels have the same dimensions to conventional solar cells, but provide more power. In halving conventional solar cells it also cuts down its current. This decreases resistance loss, making half-cut solar cells marginally more efficient.

This technology is the most efficient method to generate solar energy from the same area. There shouldn’t be much of a price difference between the two cell types.

Bifacial modules

For most solar panels of 500 watts in order to reach their wattage ratings, they build the panels bifacial. Bifacial solar panel are double-sided, which means they are able to capture sunlight and convert the energy into electricity from both sides.

Bifacial panels can only be used for utility-scale or ground-mount solar installations. The reason for this is that the back side needs to be exposed to light. This is the same reason why Bifacial panels are not suitable in roof installations, as they’d require to be placed directly on the roofing.

What is the size of the solar panel that is 500 watts? (size and number of cells)

Solar panels with 500 watts are usually comprised of half-cut Monocrystalline cell.

The average size of a 500 W panel measures 27.53 sq. feet (7.40 feet and 3.72 feet). This means that panels made of 500 W are massive, and therefore more suitable for commercial use.

For a better view take a look at the dimensions and number of cells in commercial and residential solar panels. Two modules are made by the solar company LONGi for an example.

  • Solar panels for residential use  – are solar panels made of 60 solar cells or its latest equivalent 120 cells cut in half. They typically measure at approximately 5.76 feet by 3.41 feet. Example: LONGi Hi-MO 4m
  • Solar panels for commercial use  – are larger solar panels traditionally constructed with 72 cells but are now produced with 144 cut cells. They have a bigger area, which is around 7.40 feet by 3.72 feet. Example: LONGi Hi-MO 5m

What is 500-watt solar panels are used to do?

500-watt solar panels were designed to power larger solar installations. They are used in a variety of configurations like:

  • Utility-scale solar farms
  • Commercial jobs
  • Systemes for Ground Mount

Are solar panels of 500 watts are worth the cost to your house?

500-watt solar panels have a place, but definitely not on the roof of your house. They’re just not feasible to put up or maintain, and they’re not cost-effective.

Physical size

The huge area of 500W solar panels make it difficult to squeeze them into the corners and crevices of a roof for residential use. It’s generally possible to create an solar power system that can provide more power using smaller solar panels that are more convenient to set up and spread out.

In addition, the massive physical dimension with 500 W panel make them hard to transport, which makes installation tasks more difficult.

Cost and performance

Regarding performance in terms of performance, solar panels with 500 W aren’t guaranteed to provide any advantages.

500W solar panels are usually not any superior (or less) than the standard residential panels with respect to efficiency rating and temperature coefficiency or other specs. They are rated higher in watts simply because they are larger. If you’re not careful You can get the same amount of power from a 6-kW system made of 12 500W solar panels, or the 6 kW system built of 16 375 W solar panels.

Also, it’s not the wattage of each panel that are important, but the power of the entire system. In actual fact the 6-kW system with panels that produce 375 W will cost you less but will provide the same solar power on your roof.

Summary: Not worth it

500W solar panels are typically used for large-scale installations in which the size of the panel isn’t an issue. However, they’re not the best choice for solar panels placed on the rooftop of your house.

Sodium Ion Battery

Is Sodium Ion Battery Storage The Next Big Thing In Solar?

Batteries are becoming the main component of residential solar installations. They are essential if you are looking to store energy for utilize in the event that the sun doesn’t shine or in the event of power failures. If you’re on an off-grid setup the battery will be the lifeline to your home.

The moment is when lithium Ion (Li-ion) has become the best choice for solar batteries since this type of battery is highly reliable and is available in top battery storage solutions such as those like the Tesla PowerwallGenerac PWRcell LG Chem.

However, because of shortages in supply chain logistics and cost increases for lithium, many companies are turning to more advanced battery technologies to store solar energy. One of these batteries is sodium Ion. As opposed to lithium-ion this kind of battery makes use of the most inexpensive and abundant material sodium.

Are sodium Ion (Na-ion) batteries able to take over lithium Ion batteries in the new energy storage market? Is sodium ion an option that is long-term and sustainable for solar energy systems? Let’s learn.

What is a sodium ion battery?

A sodium ion battery utilizes sodium as a charge carrier. They have an inner design of sodium Ion batteries is similar with a lithium-ion battery that’s why they’re often compared against one another. They can be recharged as lithium-ion, lead acid as well as absorption glass mat (AGM) batteries.

The development of sodium-ion batteries goes from the 1980’s and is now picking up because of the challenges associated with the expansion of lithium-ion batteries such as rising costs for materials and the requirement to acquire massive quantities of lithium to ensure batteries and supply.

There is a lot of research on the optimization of Na-ion batteries, with a focus in relation to the use of Prussian blue as cathode material. The Na-ion battery is designed to be able of taking various designs, from cylindrical ones and rectangular bags. The various shapes make them ideal for commercialization, which allows this type of battery to be utilized to store energy as well as electric vehicles and portable devices.

Battery based on sodium ion in comparison to. lithium-ion battery technology

lithium-ion battery technology

Let’s look at sodium-ion batteries to two kinds of lithium Ion batteries such as nickel manganese and cobalt (NMC) and lithium iron phosphate (LFP).

These lithium-ion batteries are among the most popular kinds of solar energy devices that are used for residential photovoltaic (PV) systems.

Table 1. Sodium ion vs. NMC vs. LFP batteries

CostCheapestCheaperMost expensive
Energy densityLowestHighestModerate
SafetySafestLeast safeSafer than NMC
Round-trip efficiency92%90-95%92-98%
Sodium ion vs. NMC vs. LFP batteries

Efficiency and energy density

They possess the lowest density of energy of all the batteries, which implies that they consume larger space than lithium Ion batteries. NMC batteries have the most energy density.

A 10 Kilowatt-hour (kWh) lithium Ion battery takes less space in the home than a sodium ion battery with the same capacity could however, they both have a similar capacity. This can be a problem when you are limited in space in your home however, as Na-ion batteries are in the process of being developed, this might alter in the near future.

Three battery technologies provide greater than 90% round-trip efficiency. That means the battery work in reducing losses in energy, making it possible for more power generated by solar panels to be stored instead of being wasted during the process of storage.

Batteries that have high round-trip efficiency can continuously supply power to appliances and other devices for long durations. LFP batteries have slightly greater efficiency for round trips as compared to NMC or Na-ion batteries. The differences are tiny and only evident when solar panels are large-scale.


The solid-state sodium Ion battery is less dangerous than Li-ion batteries since they are not flammable and are able to operate even at temperatures that are extremely high. While stable lithium batteries are, they are vulnerable to burning when not properly charged, used, or stored.

Recently it was reported that the New York City Fire Department (FDNY) issued a statement regarding the dangers of fire from lithium-ion batteries in light of numerous incidents that involved lithium-ion batteries getting caught on fire. However, these incidents are not common and shouldn’t hinder you from buying lithium-ion batteries to use for solar energy storage at home.

However, LFP is safer than NMC since it can be able to withstand higher operating temperatures and also handle more energy. As opposed to sodium-ion batteries lithium Ion batteries have been tested extensively and are backed by a long-lasting history of solar power.


Cost is one of the major factors in the use of batteries and they can add thousands of dollars a solar installation.

Sodium-ion batteries are expected to be less expensive in comparison to lithium-ion batteries since they are made of cheaper materials. Lithium-ion batteries for storage of solar energy generally cost between $7,000 to $14,000 prior to taking into account the Federal solar tax credits depending on the size and type.

Lithium-ion batteries extensively use cobalt and lithium in the process of manufacturing. The cost of lithium is growing due to inflation and the increasing demand for electric vehicles as well as batteries for home energy storage. The rapid need for lithium has resulted in an oversupply and is likely to continue to be a problem over the next few years. The sodium ion batteries don’t make use of cobalt, lithium, or nickel.

In reality, the issues that come with the acquisition of lithium are driving the development of sodium Ion batteries. Many believe that a new kind of battery must be developed to keep up with the increasing demand to store energy.


There are sodium-ion batteries that are available for purchase, however, the majority are in prototype or demo releases. The online purchase of sodium-ion batteries can be difficult and require you to submit an official request to the company that manufactures the batteries.

In contrast, lithium-ion batteries for solar energy storage are offered by many battery makers around the world. They are the preferred battery technology for consumers as well as top-selling brands or sellers. They are available for purchase on the internet or through the neighborhood solar contractor.

Companies developing sodium-ion batteries

There are many businesses that are trying to create and market sodium Ion batteries. A lot of these companies have prototypes in place and are near getting Na-ion batteries available to consumers in the mainstream.

Sodium ion

Manufacturer produces solar panels along with LFP batteries designed for use on the go as well as home battery backup.

Based in Nevada The company recently introduced a sodium ion solar generator. The generator has a capacity of 3000 watt-hours (Wh) capacity and can be expanded to meet high capacities. The achievement that manufacturer could launch the first sodium-ion battery for solar is an impressive accomplishment. Keep an eye on the firm for the best sodium Ion batteries for solar in the near future.

Contemporary Amperex Technology (CATL)

CATL is a worldwide battery manufacturer and has greater than 30 percent of the market for lithium-ion batteries that are used in electric automobiles.

Based in China the company is currently creating its first sodium Ion battery line. It’s focusing its efforts on improving the capacity of energy in the batteries which will allow for the expansion of possibilities and applications.

CATL is a major factor in the rapidly developing sodium ion battery market because it is able to scale production quickly because of its vast capacity of operation, made up of over 33,000 employees (as of 2020)

Natron Energy

Natron Energy provides a small sodium-ion battery that is designed for specific needs, such as telecoms, data centers, and rack-mounting applications.

This battery is in compliance with Underwriters Laboratories (UL) safety standards which is among the difficulties in bringing the battery into the mainstream market. The Na-ion battery has a longer cycle time and has the capacity to deliver more energy than lead-acid batteries.

While it is available for purchase, this fast-charge battery will not be sufficient to power solar panels at home.

AMTE Power

AMTE Power manufactures and develops batteries that are suitable for industrial use. AMTE Power is planning to launch a sodium-ion battery to use to store electrochemical energy and transportation, which will be available in Q3 2022. It has partnered with Faradion which is a sodium ion battery manufacturer to enhance its manufacturing as well as sales.

The battery manufactured by the company is slim and takes the form of a rectangular pouch. It’s a low-power battery and isn’t suitable for installation in homes yet.

The sodium batteries are a promising solution which is still in development

Sodium ion
The sodium batteries

Sodium-ion batteries are the next generation of options for the widely-used solar industry for residential use.

Many consider it an option to expand energy storage because when compared with lithium-Ion technology, it utilizes many of the same materials and is sustainable. The low cost of production in sodium Ion batteries can help in the deployment of products. However, this kind of battery is still in the beginning stage of production and development.

These batteries, in the form of paper, are able to offer a number of advantages over the existing lead acid and lithium batteries, particularly in terms of the sustainability aspect. However, these traditional batteries have been tested and proven to work with a long experience and track evidence of their reliability in actual-world applications. We believe that this is the key element and is what’s missing in sodium Ion batteries.

If sodium Ion batteries are shown to be an option for traditional solar batteries, in the long run, it will be much more straightforward to suggest them for home solar panels – however, only time will prove that. What can you do to determine whether sodium-ion batteries will be suitable to be used in solar panels? It is obvious when it is the best time to buy them if:

  • Local solar installation companies start by offering or recommending them
  • It is easy to purchase items on the internet.

The sodium ion batteries, so far, appear to be on the correct path to be a viable alternative to conventional batteries in the future. however for the time being it’s fine choosing the current lithium-ion batteries to power your solar system.

Why Electric Cars Are Better Than Gas Vehicles In 2022

Electric Cars
Why Electric Cars Are Better Than Gas Vehicles

Why Electric Cars Are Better Than Gas Vehicles In 2022

With several U.S. states set to outright ban sales of gas-powered cars from 2030 to 2050 to reduce carbon emissions The transition into electric vehicle (EVs) is likely. Although many consumers anticipate owning the EV in the near future most assume that it will be several years before they opt to go electric themselves.

We believe that they may make the switch sooner than they anticipate. Electric vehicles have already been recognized as an option not only for those who love driving as well as families, commuters, and other people as well.

In reality the combination of advances in battery technology and incentives from the government mean that EVs are now available at affordable prices, as well as with significantly greater ranges than they ever have been before.

Therefore, we believe that, as of 2022, electric vehicles are currently superior to gas-powered vehicles. This is why we will explain the reasons below.

reasons electric cars are better than gas cars

Electric car range is better than you think

The good news is that electric vehicles are already beginning to compete with gas vehicles when it comes to distance.

It is the Tesla Model S currently has the longest range of all EV and has an impressive 405 miles ratings from EPA. This isn’t much lower than some of the more efficient gas vehicles in terms of fuel consumption.

The EVs that have such large ranges are mostly offered by Tesla. But , to ensure fairness, let’s take a look at smaller-ranged EVs such as those offered by the Nissan Leaf and Chevy Bolt.

There are two models: Chevy Bolt and Nissan Leaf are both much less expensive than Tesla are now able to travel over 200 miles. It may seem like a lot initially but it’s actually a good amount for the majority of people. Most Americans utilize their vehicles primarily for their daily commutes that is only 16 miles. This means that once you journey home from work there’ll be plenty to make additional journeys.

If you are in need of more power in a specific day, you are able to extend your range with a simple recharge. As electric vehicles are becoming the norm, EV charging stations are popping up all over the place. They can be found using applications like PlugShare which helps you locate charging stations in your area and also offers a trip planner.

In the end, the current EV ranges don’t have to be as restrictive as they’re claimed to be.

Electric cars are much cheaper to run

Electric vehicles are significantly less expensive than gasoline vehicles in terms of price per mile. This is due to the fact that EVs can efficiently utilize their energy inputs and electricity. Gas cars, on the other hand rely on inefficient gas combustion to generate energy.

The price difference between the two has increased recently. The price of gas has increased significantly more than electricity costs – gasoline automobiles have become more costly to operate. This has led to a rise in demand for EVs for consumers by 2022.

It’s fascinating to note how the cost savings that you get by choosing an electric vehicle can be quite different depending the location you live in. This is because of how electricity costs, which can vary significantly in different states than the relatively stable gas prices.

Table. Cost to fully charge on the Tesla Model S in different states


Electricity rate (per kWh)

405 mile charging cost













New York



South Carolina









Electric rate source: EIA

Let’s look at what it costs to fill tanks of gas in the same locations.

Table. The cost of filling the tank of a car with gas across different states


Fuel price (per gallon)

Cost to fill small 12 gallon tank

Cost to fill large 16 gallon tank

















New York




South Carolina












With gas prices hovering around an average national rate at $4.242 each gallon. Filling your tank could cost you anything from $50.90 for a car that is smaller as well upto $67.87 when you have a more powerful vehicle. The fuel efficiency average for the gas-powered vehicle is 25.4 MPG, which means it costs $2,255 for the opportunity to travel 13500 miles (the average annual mileage across America). US). The high costs of fuel can be a significant cost to families in the American family.

Based on in the above table, median cost of charging the Tesla Model S is just $10.59 which is a great incentive to EV ownership. To travel the same distance of 13,500 miles it would require 33.33 costs and cost $353 in electricity and a saving of $1,902 per year. The unparalleled fuel efficiency of electric vehicles can save owners of electric vehicles money.

Of of course, if your house is equipped with a solar panel, you are able to charge an electric vehicle at significantly less than this. Get a free estimate of the price of solar panels in your region simply by typing in your zipcode here.

There are many ways to recharge an electric car

Electric Cars
ways to recharge an electric car

Although charging your EV may not be as quick as filling your tank up at an gas station. However, there’s plenty of different ways to recharge your vehicle, which differ in price and speed. We’ll look at the most popular EV charging options below.

Charge at Level 1

It is the AC 120 V power cord included with your vehicle. This method is the most slow, offering about 3 miles of charging. We wouldn’t advise relying on charging at Level 1.

Charge at Level 2

These chargers operate from a 240 V power source similar to dryers and washers and require an electrician to set up within your home. Based on the type of the electric automobile, it usually costs anywhere from $550 to $2,000.

Based on the model of your car and the adapter that is on your charger could expect between 14 and 35 miles in an hour when charging.

Installing the Level 2 charger if you’ve bought an electric vehicle is highly advised.

Charge at Level 3

Charges at Level 3 (often described as fast charging) will provide more than 100 miles in an one hour for charging. Unfortunately, Level 3 chargers are only accessible at public charging points.

Chargers for Level 3 are considerably more expensive and cost approximately $0.28 or $0.69 for kWh. This is reasonable, because otherwise it would be uneconomical for these stations to run.

It is also not recommended to rely on chargers that are fast as they have been known to harm EV batteries with time. Fast chargers are ideal to use for road trips, not daily use.

Prices are now competitive with gas cars

The most common belief is that electric automobiles are so expensive that they’re not feasible for the American population, but this could not be more far from the fact. The cost of buying a brand new car across the United States, according to KBB, is $47,077. KBB also says that the average cost of an electric vehicle is more than $56,000..

Although EVs generally cost more than gas-powered cars and high-end EVs produced by Mercedes as well as Tesla have artificially raised the price.

Even though gas cars are generally cheaper, it’s important to keep in mind that by buying an electric vehicle you won’t have to pay for gas.

It’s also crucial to remember that electric vehicles typically entitle you to an Federal tax deduction of $7500. This greatly lowers the cost of ownership for electric vehicles.

To be eligible for the tax credit, you need to have income that is tax deductible within the United States. The tax credit is also applicable on plug-in hybrids. On the flip side, Tesla as well as the GM’s Chevrolet Bolt are no longer in the tax credit category.

Make sure you check EV incentives for your state as numerous states offer rebates and tax credits as part of the federal program.

EV performance is far superior

If you’re someone who would like to go out on the track, you’ll be pleased to learn that electric cars accelerate more quickly than gas vehicles.

This is due to the fact that internal combustion engines must begin to build up its revs before it can propel the car forward, while electric motors can start moving the wheels of the vehicle immediately when the accelerator is pressed.

To illustrate this, let’s take a an examination of the 0-60 mph times of various EVs and various gasoline-powered vehicles:

Table. Comparing the speed of electric and gas-powered automobiles


Engine type

0-60 mph time

Tesla Model 3 (Performance)

5.5 secs

2021 Chevrolet Camaro RS 3LT 1LE


5.6 secs

Nissan Leaf SL Plus


6.5 secs

Honda Civic 2021


8.2 secs

It’s evident that the Nissan Leaf SL Plus, an electric vehicle that is budget-friendly with a 0-60 mph time that is only 0.9 second slower 2021’s Camaro.

And what about the Tesla Model 3’s performance? It leaves gas-powered cars behind.

EVs have much lower maintenance costs

The cost of maintenance is 40 percent lower for electric vehicles than gasoline powered vehicles. This is due to the fact that electric vehicles contain fewer moving parts – which means they have fewer potential faults – and are not subject to routine oil change.

In the coming years, the limitations placed on gas automobiles will force automakers to not be able to upgrade their fleet of gas vehicles. Why would they want to invest in making improvements to something that they won’t be able to sell? This means that gasoline cars in the coming decades will be slowly degrading and eventually, people will have no choice but to buy electric vehicles.


Electric vehicles are superior to gasoline cars. The answer is clear electric cars are the future in the coming years. Electric vehicles are cost-effective as well as easier to maintain. the fear of losing range is going to be a thing of the past.

Do Solar Panels Work On Cloudy Days Or At Night

Do Solar Panels Work On Cloudy Days Or At Night

Solar panels permit you to utilize the sun’s clean and renewable energy. This could reduce your electricity bills and also your carbon footprint. But do solar panels work on cloudy days, or during times of less-than-optimal sunlight exposure? For those who reside outside the Sun Belt, this is an important question to be considered before deciding on installing solar panels.

This article will discuss the ways solar panels function on sunny days and whether they work in the evening, and how to ensure that you have power available even when the panels aren’t producing solar energy.

What are solar panels?

Let’s begin at the beginning. Solar panel system consist of several smaller units referred to by the name solar cell. They function by collecting sunlight from our nearby sun, or the star. They convert that sunlight to direct current (DC). 

The energy they generated is referred to as photovoltaic (PV) energy. It can be translated to “light-electricity. A single solar panel can produce electricity to power one or two smaller appliances. For a solar array that could power a house or building, you’ll need a system with a lot of solar panels joined together.

How do solar panels work?

Cloudy Days
How do solar panels work?

This is a more technical and thorough explanation of how these devices function:

The solar panels work and transform energy into power (DC) The power is then sent to the inverter of the system. After that, it’s transformed into AC (AC) electricity. Do you hear a bell from your science class? 

If it’s not, we’ll remind you. AC is the energy that the majority of households rely on. This is what you will get when the utility brings electricity to your home, allowing you to stream TV make dinner, or simply switch off the light.

All energy produced by the system you don’t utilize is sent to batteries for storage or to the electric grid power We’ll discuss this in a moment. Solar systems are most effective when the maximum amount of light hits the cells. This generate electricity and the most power. It begs the question, what happens during an overcast day?

How Solar Panels Work Cloudy Days

Cloudy Days
How Solar Panels Work Cloudy Days

Photovoltaic (PV) solar PV system make use of indirect sunlight and direct sunlight to produce electrical power. This means that they can perform well even in the absence of cloud cover. In the end, solar panels are most efficient and efficient when they absorb direct sunlight during sunny days.

Although the solar panel system continues to function even when sunlight is partially obscured through clouds power production capacity will decrease. Solar panels produce between 10 and 25% of the usual output when there are dense clouds.

In the case of clouds, it’s usually rain. Here’s an interesting fact that may surprise people: It assists in making your solar panels function more efficiently. This is because rain cleans the dust and dirt that’s accumulated on your panels so that they can better absorb sunlight.

Do Solar Panels function at night?

Solar Panels function at nighty
Do Solar Panels function at night?

Although solar panels can operate on sunny days they can’t function in the evening. The reason behind this is quite simple solar panels function by a principle in science called the photovoltaic phenomenon, which is activated by solar cells by sunlight, which generates electricity. Without sunlight, the photovoltaic effect isn’t activated and therefore no electricity can be generated.

One method of determining whether your panels are producing energy is by looking at lights in public places. In general the thumb, if street lights, as well as other light sources, have been switched off – regardless of whether it’s cloudy weather or during the evening hours, the solar panels are producing energy. If they’re glowing by the sun, it’s probably too dark for the solar system’s solar cells to be able to operate.

Will solar panels work in the shade?

Even partial shading, whether from the sun or another source, can reduce how much solar output your system generates Solar systems are engineered to stop the negative effects of shading from causing energy production to cease. How much, depends on the individual solar technology–particularly microinverters.

Cloudy Days
Will solar panels work in the shade?

In central inverters, the wires that connect to the inverter are usually connected to the panels, much like lights on the Christmas tree. However, just like the light fixtures on Christmas trees, this setup could go wrong because of a tiny issue.

If you have 24 solar panels on a roof. If shade covers only one of them for a few hours each day, the whole panel will be underperforming for the two hours. Even though other panels are producing the most power, the limitations of the shaded panel will block a significant portion of their energy from going via the inverter central.

The best solar systems come with micro inverters in each panel. Each panel is separate therefore if the sun hits one panel for a few hours, only one panel will be affected. In the end, more power is delivered to the home. 

If for example 20% or more of solar panels are covered by a tree’s branch, only 20 % of your system’s energy output is reduced for a short time, but nothing more. Installers who are qualified can design your system to ensure shading issues won’t become an issue. It’s the reason it’s essential to partner with a professional solar panel installer who is certified.

Make sure your solar provider employs accredited and/or locally-based solar contractors. Every state has specific rules, guidelines, and incentives. These are in addition to geography and climate factors. 

Locally owned businesses that have expertise on the local climate and the installation rules and regulations are the best sources of information about how solar energy system can work on your home.

Does the heat or cold affect solar panels?

Solar panels don’t require hot temperatures to generate electricity. Solar panels work best when they are in sunny areas and cold. If panels reach temperatures of the temperature of 77°F, they are likely to function less efficiently. 

However, that doesn’t mean they can’t perform well in hot areas like Phoenix (which is ranked No. six on our list of the cities that have the most solar energy savings). It is true that electricity costs, not weather, play a larger part in the way solar panels can save homeowners money.

Do solar panels also lose efficiency when it rains?

Do solar panels also lose efficiency when it rains?

Like normal cloud cover, ultraviolet rays penetrate through rain, too. But, since sunlight is not as abundant as well, the amount of electricity produced. The amount of energy generated depends on the amount of cloud cover, therefore the system’s output will be uneven and will generally decrease during the dark days.

While energy production drops with the increase in cloud cover increase, solar panels are still producing more energy than you’d think. Rain also helps to wash off dirt and dust, keeping your panels in good condition and functioning efficiently depending on the season.

Does fog affect solar panel efficiency?

Cloudy Days
Does fog affect solar panel efficiency?

As with cloud cover and fog, and other low-light conditions impact solar normal power output, however solar panels still manage to absorb a portion of the sun’s energy. It’s believed that the majority of solar panels are operating at around 50 percent of their usual effectiveness in foggy conditions, which is vastly better than extremely thick cloud covers or cloud cover.

Furthermore, fog is typically burned off throughout the day (typically early in the day) which means that in mid-afternoon, when the sun is back the solar panel’s efficiency will increase to normal levels.

It’s not hurt to remember that Germany, a world leader of renewable power which has an average of more than 200 partly cloudy or cloudy day per year, accounts for around 25% of the solar power generation and saw the highest growth rate in less than the last half-decade. It’s a strong indication that solar power is about reducing cost of energy and also helping the environment rather than the sunshine.

Storing Solar Energy for use on cloudy days as well as at Night

Storing Solar Energy for use on cloudy days as well as at Night

In times of high sunlight, solar panels could produce more energy than you need. This excess power could be used to supply additional energy during the day or in the evening.

How do you save this energy for future usage? There are several possibilities to think about:

The ability to save excess energy in the photovoltaic battery

If you install a solar panel to your solar residential installation, any extra power can be used in times of low sun exposure, which includes the evening hours, and in extremely clouds.

Batteries can let you operate a solar power system for the entire day however there are a few disadvantages to solar battery storage that you should keep in mind:

  • This is another item you must install.
  • This adds to the overall price of your solar system.
  • Batteries take up some space.
  • You’ll likely require several batteries if you need power for more than a couple of hours. For instance, Tesla solar installations require two Powerwall batteries when your system is more than 13 Kilowatts.

You can utilize a program for net metering

Cloudy Days
You can utilize a program for net metering

Net Metering software allows you to transfer any excess power that your system generates to the electric grid of your local electric utility which will then be credited by the utility provider. These credits can be used to cover any electrical charges that you pay for on days with overcast skies or at night when you are unable to charge your home using solar energy on its own.

Net metering could be an efficient option for cost and could drastically reduce your electricity costs however, there are some disadvantages to be aware of, including:

  • It is possible to not always be able to make a profit.
  • In certain situations, there is a chance that you have a debt to your utility company.
  • Net Metering programs aren’t available in all regions and by all utilities.


A cloudy day, cloudy area, or rainy weather should not hinder anyone’s thoughts of switching to solar power for energy efficiency and sustainability.



Key takeaways: when will solar perform the best?

Solar systems perform best during the times when the sun shines. Because the angle and strength of the sun change through the seasons and days as well as the intensity of the sun’s radiation, which impacts the amount of energy the solar system can produce.

Which Solar Panels Work Best In Cloudy Conditions?

Monocrystalline solar panels are the most efficient solar panels to use on cloudy days. They are more efficient than other solar panels. efficiency and are more efficient than other types of panels in conditions with low light like rainy days. The Monocrystalline panel is also among the more expensive kind of panels.

What Does 'Behind The Meter' (BTM) Mean?

“BTM” is a term used to describe “behind the meters” (BTM) can be utilized in talking about batteries and storage for the energy that supplies power to your building or home without the need for a power grid. By using BTM, a BTM solar energy storage, if your electric provider experiences blackouts, you don’t lose power and will continue to utilize power at home.
