Top 8 Best Flexible Solar Panels in 2018 – Reviews and Top Picks

Whether you are choosing to use solar energy out of preference or necessity, the fact remains that many solar panels just will not work for your intended purposes. They can be rigid and bulky, making it impossible to mount in smaller, irregular shaped areas. With flexible solar panels, you have the option to tap into solar panel just about anywhere you need power, whether that is on your boat, RV or out in your off-the-grid cabin. The key is to find the best flexible solar panels for your purposes to ensure you are getting the most value for your dollar and power for your uses.

Why Choose a Flexible Solar Panel?

You may be wondering why you should choose a flexible solar panel over a traditional style. The answer is fairly simple. It comes down to your intended use. If you have somewhere you need to mount the panel that is not flat, straight or perfectly level, you may run into problems installing a traditional solar panel.

With flexible panels, you can bend and form-fit each panel accordingly. Imagine having a round travel camper, which you want to generate enough solar power to run without any other power source. Traditional panels would be difficult to install on a round roof and would likely end up falling off. Flexible solar panels are mountable on most shapes and sizes.

Along with their bending characteristics, flexible solar panels are very lightweight in comparison to classic style solar panels. Most flexible ones are constructed of plastic whereas traditional styles are made from glass, steel and metal. This allows you to apply them in most situations.

How to Choose the Best Flexible Solar Panels?

Not all flexible solar panels are created equally. With a little research and comparing, you will find the perfect one for your desired use and needs. When shopping for a solar panel, especially a flexible model, you should keep in mind some key points and features that are important to the functionality and purpose of each. These features will help you determine which one is right for you.

Size and Weight

When examining different options, you should consider the size and weight of each panel. If you are intending on using your flexible panels in a smaller spot, you will want to choose a product that is on the smaller side and is very lightweight. However, if your desired purpose is on a larger scale, size may not be such an important factor. However, smaller and lighter make it much easier to transport and mount.

Wattage

Of course, you should consider how many watts the solar panel will output, since obtaining power is the sole reason you are buying a solar panel in the first place. Lower watts mean less energy output and could also mean you will need to connect multiple panels to get the desired power level.

Flexibility

It goes without saying that if you are in the market for a flexible solar panel, you expect it to be just that—flexible. However, in terms of just how flexible the panel is, you could examine how far the panel can bend without worry of breaking. This is usually measured in degrees. This feature would be important for anyone planning to mount their panel on an irregularly shaped object/vehicle.

Durability

Since you will be using the panels outdoors, you want them to be tough and stand up to different weather conditions. This is especially true if you live in a climate with extreme weather changes. The panel should be water-resistant and not get bogged down by dust or sand.

Cell Efficiency

What is meant by cell efficiency is how quickly the cells in the solar panel will turn the sunlight into usable energy. The average range is between 11 to 21%. The higher the percentage, the faster you will have access to that sunlight power! Have a look at the panel you are considering to find its rated efficiency.

Ease of Installation

This is a key point to make, since it is often overlooked in the buying process. If you are not familiar with mounting solar panels or are not handy, you will want to find a flexible solar panel that will not take much of your time to mount. Some panels will be much easier to install than others, so read carefully how you must install or mount them before you purchase.

Additional Accessories

When choosing your flexible solar panels, you should consider what additional accessories you may require, and which ones are included with the panels. If the cord on the panel is rather short, you will probably need an extension. Check to see if the panel you are considering includes an assembly tool. If not, you will need one for installing it.

How To Install Flexible Solar Panels?

Once you have made your decision in which flexible solar panel is the best one for you, you may start to have questions such as how to set up your new flexible solar panels. In most cases, installation is fairly simple depending where they are to be mounted.
If your new panels have pre-drilled grommets, you may opt to screw down your panels for ultimate security. However, if you don’t want to drill through your boat roof/RV/Cabin etc., then you could lay a backing of plywood and screw the panel to that instead. Alternatively, you can use adhesive glue or tape which usually holds the panel securely without damaging your surfaces.
Once installed, you will want to set up the entire system, so you can start harnessing in that sunlight power.

In Conclusion…

It is not impossible to find the best flexible solar panel on the market for your exact needs and uses. With some simple research and comparison shopping you will know exactly what you are purchasing and if it will work where you need it to.
