Abstract

In this research the results of most commonly used mathematical model for description of electrical values in PV modules are compared to measured results. This model is usable in most of advanced systems for PV system energy production utility improvement. In order for these models to be used it is necessary to provide the correct values of model parameters. In this paper the method for determining basic parameters of serial and parallel resistances, equivalent diode and current source entirely using PV module nominal data. The results of this method are compared for with specific operating point of maximum power.
