Abstract

• This paper investigates on a simulation model for a PV panel to allow estimate the electrical behavior of the panel with respect changes on parameters of shade and temperature. The simulation model was implemented in Mat lab and accepted the I-V characteristic outputs as variable parameters the effects of shading and temperature of solar PV module. This model is quite and especially useful to analyze the performances of the PV modules under various operating conditions. It is simulating the parameters for the nonlinear I-V equations based on only the solar panel such as open circuit voltage, short circuit current, voltage and current at maximum power point at the standard test condition which are obtained from manufacturer’s solar panel. The performance of PV panels is affected by the shading and temperature effect due to trees, passing of clouds, neighboring buildings. The aim of this research work is to use the change in electrical parameters with shading and temperature of PV solar cell and module. The simulation results show that the electrical parameter such as the open circuit voltage, short circuit, maximum power decreases as the shading and the ambient temperature increases.
