FAQs

1. Are Flexible Solar Panels Any Good?

Flexible solar panels are ill-famed for their lower efficiency compared to regular glass panels. But they are great choices for easy mounting over uneven surfaces like a boat deck, RV roof, camping tent, and more.

Because of their low efficiency, flexible panels are not recommended for residential use. It is because they will take up more roof space to meet the ideal power requirements for a home.

2. What Are the Best Flexible Solar Panels?

When buying flexible solar panels, make sure you get the models with quality components. There are a lot of low-quality products that are made of cheap plastic and other materials, which will break up easily.

Brands like Renogy, PowerFilm, SunPower, and Topsolar have been long offering quality flexible solar panels. An ideal flexible solar panel is bendable up to 30 degrees.

3. Do Flexible Solar Panels Last?

Flexible solar panels are expected to get a lifetime of 10 to 20 years only. It is when classic rigid panels have a lifetime of over 25 years, and most of the brands offer a warranty of a minimum of 25 years.

As they are made of plastic and thin-film solar cells, flexible solar panels may get damaged in a short term. But they are quite easier for you to use in various off-grid applications.

4. Do Flexible Solar Panels Overheat?

Yes, they do. As they are made with thin-film plastic and solar cells, they may heat up faster than regular panels. Overheating is indeed one of the key reasons why flexible solar panels are less efficient. Also, when you mount them over the metal roofs of your RV or boat, they may even heat up the interiors.
