Abstract
Abstract A system is disclosed for converting solar radiation into electricity and for storing energy generated in excess of demand. The system includes a large circular collector fabricated from modular elements. The collector is combined with a concentrator and boiler for producing steam. The steam produced is used to drive an electrical generator and a hydraulic pump. When system demand is less than the capacity of the generator, the excess energy is used to drive the pump. The pump transports water from a low level reservoir to an elevated reservoir, thereby storing potential energy. Later, when demand increases, water from the elevated reservoir is used to drive a second electrical generator. The circular collector is mounted on tracking apparatus which automatically aims the collector to focus on the sun and receive maximum solar radiation on its surface.
