Abstract
The analysis of the performance of a photovoltaic (PV) array needs basically the reporting the real working conditions to a reference condition of irradiance and temperature. Normally it is used the Standard Test Conditions (STC). Then the corrected I-V curves can be compared and an analysis of the performances can be carried out. In this context this paper proposes an analytical model to evaluate the energy performance of a PV module. The proposed model is based on some data provided by the manufacturer of the module in STC conditions. The photovoltaic module used as test-bed in the experiments gives the possibility to have the six terminals of the three strings forming the module, that normally are connected in series. This is very useful in the case of shading or disuniform radiation. The model is validated with numerical examples, and tested using both measured and estimated data relative to each single string and their connection in series and parallel. Results show how the parameters extraction depends on the measured value of the maximum power points, if measures are not accurate the analytic model here implemented can not converge to a feasible solution.
