NOVELTY - The system has a photovoltaic cell panel (3) collecting energy from the sun, and a five stage compressor (9) powered by the energy derived from the panel. A pressure vessel is formed inside an inner wall of high pressure storage tanks (7a-7d), and an annulus is formed between the inner wall and an outer wall of the tank. Valves (25, 27) and a two directional pump (23) control flow of water from containers (17, 19) to the annulus. An electrical generator (43) generates electricity when the compressed air is released within the vessel by a multi stage turbo expander (41).    USE - Solar energy storage and enhancement system.    ADVANTAGE - The system comprises two solar receiving panels to heat water which can be circulated and stored within an annulus surrounding the inner vessel, thus regulating the temperature of the compressed air within the tank, and hence avoiding any excess temperature drops that result from air expansion. The overall system efficiency is enhanced by the chilled air by-product of the turbo expander which is used to generate more electrical power from an associated fuel-driven generator set and by the waste heat from the compressor and from the generator set exhaust, in a cost-effective manner. The inner wall is designed to withstand a nominal amount of air pressure such as 200 pound-force per square inch and the outer wall is preferably designed to withstand over 1,300 pound-force per square inch, thus enabling the system to withstand overall internal air pressures of more than 1,300 pound-force per square inch. The system enables compressed air to be released and expanded to produce electricity and creates chilled air as a by-product to provide cooling for an ancillary device such as heating ventilating and air-conditioning (HVAC), refrigeration or desalination device, and, while utilizing heat derived from the compressor to be used in ancillary systems such as for showers, laundries, baths and absorption chiller.    DETAILED DESCRIPTION - The compressor is also powered up by a power grid, geothermal plant, nuclear plant, a wind farm or a wind turbine generator. An INDEPENDENT CLAIM is also included for a method for utilizing and storing solar energy and enhancing efficiency of a compressed air energy storage system.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a solar enhancement system including a photovoltaic panel, two solar receiving panels, storage tanks and the turbo expander set with generator.
