CIRCULAR ARC SOLAR CONCENTRATOR

摘要

A solar energy concentrator and collector having a concentrator made up of one or more anticlastic panels that feature a non-developable doubly curved surface. The panels are concave in the north-south direction and convex in the east-west direction. In one embodiment, the panels are formed to have parallel circular arcs in the north-south direction of increasing radius from the center of the panel to its edges and having a curved cross-section in the east-west direction. The concentrator reflects light to a narrow zone of concentration which moves within a plane in response to changes in the angle of incidence of sunlight thereon. A method for forming the specially shaped reflective fiber reinforced plastic panel is also disclosed.
