Low voltage photovoltaic (PV) array delivers electric power to the renewable energy systems which utilize step-up DC-DC converters. The performance of PV array is strictly dependent on environmental conditions such as solar radiation and ambient temperature. In this paper presented is MATLAB model of low voltage 3.2 kWp PV array composed of ten PV panels connected in parallel. The model itself is based on photodiode model and is supported by datasheet parameters of examined PV panels. Presented P-V curves show an influence of solar radiation and temperature on electric power produced by the array. The model simulation results were verified on computer aided laboratory test setup built upon LabVIEW environment. The test setup comprised PV array connected to 6 kW electronic DC load which was controlled by LabVIEW application. Since test conditions should be steady during test time each measurement of real PV array full P-V curve has to be done as quick as possible. This can be assured by computer aided measurement approach where time consumming tests can be easily automated and shortened. This paper presents PV array model, describes test setup and discusses laboratory test results.
