Title: Tracking Solar Energy Conersion Unit Adapted For Field Assembly

Abstract

A modular solar energy collector having elongated V-shaped side walls formed by a pair of coplanar panels for each side wall. The upper panels, occupying most of the wall area are diffusely reflective, but the lower panels are specularly reflective. A Fresnel lens, having a snap fit relation to the side walls focuses some light on the lower specularly reflective panels which direct light to the solar cells at the base of the V-shaped walls. A heat sink provides support for the two panels with two opposed, upwardly extending wings terminating in opposed linear clips located near the lengthwise seam of the coplanar panels, each clip holding two coplanar panels in parallel alignment. The clips not only provide support for the panels, but also transfer heat to the remainder of the heat sink. The clips are shaped so that edges of the panels engage each clip by a snap fit, outside of the clip in one embodiment and inside of the clip in another embodiment. End caps are also formed with structures which snap to the wall panels. Since all junctions of components snap together, the collector of the present invention is easily assembled without specialized tools. Using side wallsmore » which are only partly specularly reflective permits a large angle of acceptance, yet provides an economical wall design because the entire wall need not be specularly reflective.
