An analysis of a photovoltaic panel model: Comparison between measurements and analytical models

This paper focuses on an analysis of accuracy degree of a photovoltaic panel model. Therefore, a brief review of one-diode model having in view the main analytical equations of this model is presented in the paper. Based on this model and its required parameters evaluated based on the datasheet of panel, various simulation studies have been carried out in order to evaluate the influence of irradiance and temperature on the current-voltage and power-voltage characteristics curves. A comparison between values of the one-diode model and those obtained from real measurements, having in view the operational parameters of photovoltaic panel, has been also conducted in the paper.
