Performance analysis of a 310Wp photovoltaic module based on single and double diode model

Abstract

This paper presents a complete simulator developed in Matlab™ for a photovoltaic (PV) module. The most important contributions of the paper is the use of single and double diode model to simulate a PV module. In the paper are also implemented numerical methods to provide more characteristic parameters that are not provided by the manufacturers such as Rs, Rp, Ipv, I01 and I02. The numerical methods are suitably implemented to face the nonlinear nature of I-V and P-V curves that are characteristics to PV output. The accuracy of the simulator using single and double diode models is verified by applying the data-sheet from manufacturers. Furthermore, the double-diode model simulation results performed in Matlab™ are analyzed in comparison with the experimental data of a real 310 Wp photovoltaic module unit. The paper also highlights the effects of different shunt and series resistances and how it operates in different temperature conditions and irradiation levels.
