Refracting solar energy concentrator and thin flexible fresnel lens
TLDR
In this article, a thin flexible fresnel lens is used to focus incident solar radiation not normal to the lens onto a target area by refraction in a solar energy concentrator.Abstract:
A solar energy concentrator (20) including a thin flexible fresnel lens (24) for focusing incident solar radiation not normal to the lens (24) onto a target area (26) by refraction. The fresnel lens (24) is supported or suspended above the target area (26) by a frame (22) and folded along at least one line or region (28) parallel to the refractive prisms (32) of the lens (24) which are generally parallel to the axis of the target area (26) whereby the fresnel lens (24) opens toward the target area (26). Thus the fresnel lens (24) is so positioned so as to allow it to bow and flex under wind loads, gravity and other environmental factors without causing significant deterioration in the efficiency of the system.read more
