ABSTRACT:
What are disclosed are method and apparatus improvements in a heliostat for reflecting solar energy onto a collector, the heliostat having a main support structure with pivoting and tilting motors and controls and mirror modules for reflecting the solar energy. The improvement is characterized by one of a combination, or curved, or lightweight mirror module in which the curved mirror focuses the energy more precisely, attenuates differential expansion due to temperature change, yet is simple and economical to build and is light enough in weight to enable building larger modules for the heliostats, as well as building larger heliostats. The specific improvement is characterized by a curved mirror formed over a plurality of templates with longitudinal support beams holding it into the predetermined curvature with transversely extending structural beams and attachment bolt for attaching it to the heliostat. Also disclosed are specific preferred methods steps and structural components.
