PowerFilm R15-600 9 watt 12 volt solar panel Because PowerFilm integrated solar panels (thin film on plastic) are developed and manufactured with a proprietary roll-to-roll process, by PowerFilm, they are truly rollable unlike other thin film technologies that are only somewhat flexible. PowerFilm solar panels are 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. Also PowerFilm performs well in diverse enviroments, including hot sun, and does not suffer from wasted over-voltage.
