Developments in the integrated CPC
Abstract
The authors present a novel collector system using an evacuated nonimaging concentrator as a secondary for a circular primary mirror. The system was developed using a general design method that tailors the reflector shape to better match the input distribution of light reaching the secondary`s aperture. This technique, which uses a complimentary edge ray to simplify the geometrical formalism, recovers familiar designs for uniform input distributions, such as CPCs. The design and predicted performance of a novel two-state 2-d solar collector with a fixed circular primary mirror and nonimaging secondary are presented. This newly developed secondary gives a 25% improvement over conventional CPC secondaries. The technique may also be applied to stationary concentrators with variable load.
