A stowable and deployable concentrator for solar cells. A substrate mounts a row of solar cells. A row of Fresnel lens elements is mounted to the substrate so as to be deflectable toward the substrate in a stowed configuration and biased away from it in the deployed configuration. The Fresnel lens is linear and flexibly mounted in a shaper which shapes it to a proper curvature in the deployed configuration. A pair of these concentrators can be hinged together to form a conveniently stowed and readily deployed combination.

Stowable and deployable solar energy concentrator with fresnel lenses

A stowable and deployable concentrator for solar cells, A flexible, springily resilient Fresnel lens is held in a frame whose relaxed condition holds the Fresnel lens as the linear fragment of a cylinder. When in this deployed shape, the Fresnel lens concentrates energy onto a strip of solar cells, The frame is springily mounted by support means, biased toward the deployed condition, and when the Fresnel lens and frame are pressed toward the cells, they tend to flatten toward a stowed condition.
