Thedesign and construction of miniature prototype of nonimaging planar concentrator,which is capable of producing much more uniform spatial irradianceand reasonably high concentration ratio, were presented in the previouspaper. In this paper, we further explore the optical characteristicsof the new concentrator that is specially designed to beincorporated in concentrator photovoltaic systems. For this study, we havecarried out a comprehensive analysis via numerical simulation based onall the important design parameters, i.e., array of facet mirrors,f/D ratio, receiver size, and the effect of sun-tracking error,which lead to the overall optical performance of the newconcentrator.
