Abstract: The aim of this work is the validation of a regression model to forecast the cell temperature of a photovoltaic module under different conditions from those for which it was fitted. In a previous article, a model which uses as inputs the air temperature, the incident irradiation and the wind speed was proposed to forecast the cell temperature. To know if this model could be universally used, the cell temperature of a module of the same technology installed in another location with different weather conditions has been computed using the coefficients estimated previously. From the obtained results, it can be concluded that the model is able to predict the operating temperature of the generator of a power plant and could be applied to this technology at any location regardless of the weather conditions.
