We present a simple low concentrating solar module design capable of boosting solar cell output by 25% (standard test conditions). The design has a theoretical concentration factor of ~1 Ax and (unusually for CPV) does not require tracking, although the design benefits from tracking. Our design employs flat reflectors, depth of module, and simple geometric principles to boost output. Any solar cell technology can be used in the design. We present a simplified cost model useful for estimating the savings inherent in this design, which depends on relevant factors like the relative costs and efficiencies of the solar cells and reflectors used. We discuss test results from testing of the first generation prototype module. We also discuss design changes that were made in building a second generation prototype module, with the intention of improving the module's performance. Finally we discuss a closely related 2x concentrating module design which should boost cell output by 50% (2x design has not yet been built/tested).
