The invention relates to a method and apparatus for using solar energy to enhance the efficiency of a compressed air energy storage system (and visa-versa). The apparatus comprises a photovoltaic panel to drive a compressor, which provides compressed air energy into an inner vessel housed within a storage tank. Two solar receiving panels are used to heat water which can be circulated and stored within an annulus surrounding the inner vessel, wherein the heated water can help regulate the temperature of the compressed air within the tank.
