PowerFilm 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 and performs well in diverse environments, including the hot sun, and does not suffer from wasted over-voltage. Includes RA-2 12V Female Cigarette Lighter Adapter and RA-11 15' Extension Cord with O-ring Battery Terminal Connectors. Rolled Dimensions: 4" x 14.5". Unrolled Dimensions: 14.5" x 42".
