Things to Consider While Buying the Best Portable Solar Panels
What Type of Portable Solar Panels Do You Need?
My vision for portable solar panels may not be the same as yours, or to put it in more precise terms my requirement for solar power that is portable could be different from yours currently.
The most efficient solar panels for portable use for RVs may not be the ideal portable solar panels to use while camping or even for parties.
This is why this review contains three kinds of solar panels for portable use:
- Foldable solar panels — like the Bluetti PV200 and SolarSaga 100W
- Rigid frame compacts — like the SunGold Power 200W and Renogy 100W
- Ultralight foldable solar panels — like the Nekteck 28W and Goal Zero Nomad 28W and BigBlue USB 28W
Portable solar panels that fold and are that range from 100-200 Watts are the ideal all-purpose solar panels. They can be used to provide power to your RV, outdoors cabin or boat yet are small and light enough to be packed with your camping equipment. Compact solar panels typically come with holes that are pre-drilled. This makes them simple to mount on all types of rooftops and mounts.
They are built with stronger (but they are also heavier) frames. They make a great option for those who aren't looking to mess with their panels too much after they've install them.
The ultralight solar panels are simple to carry in a backpack or put in your trunk, even when you own an automobile like a Chevrolet Spark. The solar panels that fold up are made to be carried wherever you go, making them perfect for picnics, beach parties and hikes.
They have plenty of eyelets, so you can simply attach them onto your backpack or tent and also provide directly USB charging for your devices.
What's Under the Hub?
Of course, the size and wattage aren't the only factors to be looking for.
While all solar panels for portable use examined here contain single-crystalline solar cells that provide the best efficiency but the market is overflowing with cheaper but less efficient
- Solar panels made of polycrystalline — You will be able to recognize them due to having more lines of crisscrossing as many silicon crystals are combined together into one unit.
- Solar panels made of thin film The majority of the time they don't even contain visible solar cells but an array of thin layers of photovoltaic film that is applied to glass or plastic.
The thin-film panels for solar are most flexible of the three and you could even think they're the most suitable choice for solar kits that can be carried around.
Maybe they were in the past when they were at the top of technology. According to current standards thin-film panels exhibit a remarkably low efficiency, ranging from 7 and 10 percent. Then compare it with the solar panels that are portable in this list that all have efficiency that are 20% or more.
If you're interested in my suggestions opt for monocrystalline solar panels. They may cost more in the beginning, but they be more durable than polycrystalline or thin-film solar panels.
The polycrystalline solar panel last roughly the same as monocrystalline panels of 25-30 years, but their effectiveness declines with time.
Portable Solar Panel Use Cases
How you envision yourself using your solar panels for portable use will assist you in making the right decision.
If you're an avid RVer like I am, the good reason is that plenty of great alternatives for portable power are readily available today. A good solar panel kit will fulfill all your RV's needs for power, including appliances in the kitchen and TV.
Are you looking to charge your phone or camera while on the road?
Look for soft-lined solar panels that you can put to the roof of your tent for maximum exposure.
In the case of boats, you can choose either foldable or a rigid frame. The most important thing is to pick a boat with an IP67-rated protection that is able to take a few splashes or even an occasional dip.
How much Wattage Do You Need to Choose?
The wattage of your solar panel is directly related to the method you're planning to utilize your solar panels for portable use.
Let's be clear right from the beginning If you're looking to power your electrical appliances as well as lighting within your RV or in an off-grid cabin, avoid the cheapest solar panels that are portable and instead look at the 100 and 200W models..
How much combined wattage do require?
Every electronic device has a specific power consumption that you can locate on the lower label.
For instance, if are looking to power a 500 watt refrigerator, you'll need three 200W panels.
The sun's output isn't always flawless. Also, there's shading dust, temperature, and shading that can affect the performance of the solar panels. This is the reason why you should choose more watts than what you really need.
There is a way to do it I recommend that you power your appliances with an energy controller or a power station. We'll talk more about that later.

How Many Panels Do You Need? *Hint: One Might NOT be Enough!
I am often asked about whether having just one solar panel with a large capacity power generator is sufficient.
In the end, a 1000 and 2000-watt sun power source with an enormous battery will manage the majority all of the appliances you own. However, it is important to remember the solar generator must be charged.
How many hours of sunshine per day could you receive?
Combine a 100W solar panel with a solar generator that's 1000Wh and it will take about 10 hours to charge and that's under ideal conditions. It's not possible to have the time.
Imagine the possibility of having three or more appliances connected simultaneously.
Ideally, your panel's total power should be enough to charge your solar panel from 0-100 within two hours.
So, will it be turn out to be 5x100W panels or 3x200W? It's your choice.
How to Setup Your Solar Panel for the First Time?
Because the solar panels are portable the procedure for installation differ when the installation of an array of solar panels to cover your entire house.
3 Steps to Setup Your Solar Panel
Check that your solar panel has the solar charge cable. The cable connects many panels to the solar generator or battery.
Find the ideal spot to put the panels on the roof of your RV or tent or even on the ground. The panel should have a consistent amount of sunshine all daytime. Utilize the panel's own kickstand, or tie it up using paracord.
Attach the solar panel with your generator. The generators come with inverters, fuses, batteries and control panels So you will always be aware of how much energy is being utilized and the amount it's charging for solar.
Thieves, Stay Away From My Portable Solar Panels!
Solar panels for portable use have many benefits, but there are they also have disadvantages. If you are able put them up and take them down with ease and quickly, then anyone else can too!
To stop this from happening to avoid this, you can shield your solar panels by securing them in various ways.
You can purchase an alarm system for your solar panels which detects movements that are irregular like when someone is trying take them off your RV's roof.
It is also possible to make removal a little less difficult by fixing them using the steel nuts and bolts, instead of paracord.
You can also put in an HD camera that has an motion sensor and a floodlight that activates only when someone enters the space where you have put the solar panel.
How to Make Your Portable Solar Panel Squeaky Clean?
Today, solar panels have a self-cleaning coating that assists in removing dirt and other debris. Remember that sap, dirt and dust build-up can reduce the performance of the solar panel you have on your hand.
But, particularly after prolonged usage, you'll need to contend with bird droppings as well as sap from trees, which call for intervention from you:
Use water that is fresh to get rid of dust particles, leaves, and other debris that didn't stick. Avoid using pressure washers since you could harm the panel. Be sure to avoid using any scrubber. Let it sit for a while.
Once you've cleaned dirt and dust, prepare the mixture using hot water with neutral soap. Apply the mixture and gently scrub using the sponge. If required, apply denatured alcohol for more permanent staining.
