Many currently used models to simulate the performance of photovoltaic cells and modules need physical parameters, e.g. series and shunt resistance, as input. However, these parameters are not readily shared by manufacturers on datasheets. Thus, models that use only electrical parameters, e.g. open-circuit voltage or short-circuit current, which are easily accessible, become more important. The model proposed in this paper uses only electrical parameters to accurately model the behavior of photovoltaic modules under changing operating conditions. We show that the approximation of the series resistance as a temperature dependent parameter greatly improves the model accuracy. The here described model will help researchers and companies to quickly and accurately model the expected output of their photovoltaic modules under real environmental conditions.
