ABSTRACT:
The reflector support structure includes a plurality of substantially straight rod-like elements which are secured together at their respective ends, forming joints, in such an arrangement so as to describe a generally paraboloidal shape comprised of a plurality of open triangles. Elongated standoff elements extend outwardly from at least the joints of the reflector support structure and have secured thereto positioning elements for supporting the apexes of triangular-shaped relfecting sections. A plurality of reflecting sections are arranged to substantially mate along their respective edges, and are held in place by the supporting elements, to form a large, substantially parabolic, reflector. When the reflector and reflector support structure are used as part of a solar collection system, a tracking support structure supports the reflector support structure off the ground and in a correct orientation relative to the sun.
