Impact of Non-Uniform Irradiance and Temperature Distribution on the Performance of Photovoltaic Generators

The use of photovoltaic (PV) panels has increased rapidly in the last few years and as a result become one main sources renewable energy. In this context, it is important to understand detail how PV panel reacts different environmental conditions these affect total performance. An experiment been designed investigate performance under various highly non-uniform temperature irradiance profiles, generated by artificial lighting. Measurements distribution are related measured I–V curves used input five-parameter model. results show limitations model emulate response such extreme provide useful insights about effect profile on
