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.
