Quantifying the Solar Simulator Requirements for Indoor Testing of CPV Modules

Manufactures of Concentration Photovoltaic (CPV) modules share a need for indoor testing, implying an appropriate artificial light source. This source must be highly spatially uniform and have a collimation angle similar to that of the sun. In this work, we report the results of a detailed sensitivity study of these two parameters, in order to provide a quantitative basis for setting the requirements for future simulators and in international standards.
