Abstract:
1. A concentrator photovoltaic solar cell array system for producing energy from the sun using a plurality of sun-tracking solar cell arrays, each array comprising: a central support having a stationary first member and second member, the first member being hollow and cylindrical and mountable on the ground, and a first, base end of the second member mounted within the cylindrical first member, the second member extending from the ground mountable first member and being capable of rotation relative to the stationary first member about its central longitudinal axis; a pair of inclined arms that extend respectively from the base end of the second member; a support frame carried by a second, opposing end of the second member and the pair of inclined arms, the support frame being rotatable with respect to the central support about an axis orthogonal to said central longitudinal axis; a generally rectangular planar solar cell array having a predetermined aspect ratio for producing in excess of 18 kW peak DC power on full illumination including a plurality of triple junction III-V semiconductor compound concentrator solar cell receivers mounted on the support frame; and an actuator for rotating the central support and the support frame so that the solar cell array is maintained substantially orthogonal to the rays from the sun as the sun traverses the sky.
