Effective use of photovoltaic (PV) modules requires reliable models for a number of applications, such as monitoring the performance of PV systems, estimating the produced power and plant design, etc. Development of accurate and simple models for different PV technologies remains a big challenge. In this paper, a comparative study of seven implicit and explicit models, published in the literature, is presented. The predicted current-voltage characteristics of the main commercial PV module technologies (multi-crystalline Silicon, Copper Indium Gallium Selenide, and Cadmium Telluride), have been compared both with the ones from the datasheet and with the ones obtained experimentally. Moreover, the investigated models have also been evaluated in terms of accuracy, required parameters, generalisation capability and complexity.
