Validation of Photovoltaic Electrical Models against Manufacturers Data and Experimental Results

This paper presents two models that describe the electrical behavior of photovoltaic modules. One of them is an easy to compute three parameters model, with a simplified power output calculation algorithm, whereas the other is a more detailed four parameters model. Both models take as input only readily available manufacturers´ data. They are validated against the catalogue I-V temperature and irradiation curves. Furthermore, a performance comparison with experimental results is presented too. Obtained outcome allows the conclusion that both models simulation results are quite satisfactory, thus providing a way to prove the accuracy of the three parameters model.
