Abstract—Line-focus Fresnel concentrating PV module can improve the power efficiency because of concentration ratio growing. But there is another problem which non-uniform illumination can influence electrical performance parameters, such as short-circuit current Isc, open-circuit voltage Voc, fill factor FF and power efficiency η. How to assess the electric performance of non-uniform PV module is becoming an awkward problem. The whole equivalent circuit, including the darker and brighter PV parts, was analyzed. And electric performance forecasting algorithm was designed by MATLAB software according to equivalent circuit and basic principle of solar cell. In the end, actual electric performance of Line-focus Fresnel concentrating PV module was characterized by SourceMeter○R instrument. The characterization shows that actual testing results were in accordance with forecasting algorithm.

Index Terms—Non-uniform illumination, line focus fresnel concentrating PV module, electrical performance, MATLAB algorithm.
