Childers, C M

The design, tooling, manufacturing, and testing of a new cast acrylic Fresnel lens array which is used as a solar concentrator are described. The array consists of twenty-five (25) single lens elements which are 6.7 inches square; the overall array size is 34.5 inches by 34.5 inches which includes a mounting border. These lens arrays will be used to focus sunlight at a net concentration ratio of 96/1 on passively cooled silicon cells in state-of-the-art concentrator modules. Tests at Swedlow and Sandia have indicated that lenses developed for this program have exceeded the lens transmission efficiency goal of 79%.
