Abstract :
A new method for the estimation of the five parameters of two-diode PV model is presented in this paper. This method allows obtaining dynamic series and shunt resistances versus climatic condition changes. Compared with five parameter estimation method based on STC condition, this method shows to be more effective with the variation of the irradiance and temperature of the PV module. Simulated I-V curves are compared to experimental characteristics for a mono-crystalline PV module under different temperature and irradiance. The results reported in this paper confirm that the presented algorithm performs better than the STC one. Finally some considerations about the impact of the variations of the series resistances on the PV module performance are drawn.
