Worldwide Energy has developed the Solar Energy Powered Unit. This unit is able to be used in disasters or areas that are prone to outages in restoring power for a period of 10+ hrs. Other back-up systems use propane, diesel or fuel generation, which makes them costly to operate. The SEP can be powered by solar, electrical, or by a car battery at minimal cost. It is a portable unit that is used indoors. There is nothing like it in the market.
