PowerFilm R-21 Rollable Solar Battery Chargers

12 Volt systems can be directly powered with PowerFilm® Rollable Solar Panels. As with any solar technology, the solar panel power output must be greater than the power consumption of the 12V system.

Power Film integrated solar panels (thin film on plastic) are developed and manufactured with a proprietary roll process and they are truly rollable unlike other thin film technologies that are only somewhat flexible. PowerFilm® solar panels are all monolithically integrated which eliminates the need for damage-prone manual connections of individual solar cells. PowerFilm® is made of silicon, a natural resource in abundant supply. PowerFilm® is Cadmium Free, unlike some other solar technologies, and performs well in diverse environments, including hot sun, and does not suffer from wasted over-voltage.
