Abstract: A solar concentrator, which is modular, durable, lightweight, and cost-efficient is described. The solar concentrator is constructed from a plurality of interconnected reflector panels that are secured to a contoured support frame assembly by means of an adjustable fastening mechanism. The reflector panels are preferably fabricated from a low-cost composite material and have an optically flat front surface. A specularly reflective front surface is formed on the reflector panel by deposition of a plurality of thin films which are highly reflective. Individual reflector panels can be interconnected and arranged into a two-dimensional grid having a predetermined degree of curvature by means of the contoured support frame assembly. Electromagnetic radiation incident upon the reflector panel arrangement is reflected to and concentrated upon a collector plate or receiving surface or receiver where it may be converted into a usable form of energy.
