CIGS (Copper Indium Gallium Selenide) is a thin-film solar cell technology that improves the durability, light sensitivity, and lifetime of our solar panels. BougeRV 100-Watt Thin-Film solar panel has a greater absorption coefficient, and it’s considerably thinner, leading to incredible flexibility. It can work effectively on uneven surfaces such as roofs of RVs, boats, or any camping site. They can suit the surface the normal rigid solar panel can’t. And you can have peace of mind about its working efficiency. Take a 100w flexible solar panel and not be afraid of extreme weather and support your brave journey.
