Abstract

An array of solar collectors includes dual axis reflectors for directing solar radiation to receivers at focal points of the reflectors. Solar radiation is used to heat a thermal energy storage material, which may be used to generate steam for use in power generation with the aid of a turbine. The dual axis reflectors may pivot about independent axes of rotation, thereby enabling use of the reflectors throughout the year.
