Featuring a lightweight, weather proof and flexible solar panel that can be interchanged between bag modules, gives Solarpac users the choice of harnessing the phenomenal power of sunlight. Derived from military origins, the revolutionary CIGS technology is so robust that if a bullet were to pass through the panel, it would still work by drawing power from surrounding cells. A variety of optional accessories including additional solar panels and high capacity batteries add extra utility to the Solarpac range.
