Solar flux distribution analysis of Non-Imaging Planar Concentrator for the application in concentrator photovoltaic system

The design and construction of Non-Imaging Planar Concentrator (NIPC), capable of producing much more uniform spatial irradiance and reasonably high concentration ratio, have been presented in our previous research paper. In this study, we would carry out a comprehensive analysis through the numerical simulation on solar flux distribution at the target by considering all the important criteria to improve the overall performance of dense-array concentrator photovoltaic system, which are the maximum solar concentration, uniform illumination area, spillage loss etc. Maximum solar concentration ratio and percentage of energy in uniform illumination area are plotted for different cases. In general, the simulated results have shown a reasonably good uniformity of solar irradiance and high concentration ratio at the receiver plane.
