It can be used where grid electrification is not available and also to supplement it. It generates enough power to provide adequate lighting, entertainment and also can power a fridge or a freezer (View the brochure). The initial system supplied consists of three interior lights that can be used for eight hours a night, one exterior security light, a 75W panel, a 102AH battery, stainless steel battery box all necessary cable and a solar panel roof- or floor-mount bracket.
