Simulation and Comparison of Modeling of Photovoltaic Modules During Different Values of Solar Irradiations Whilst Temperature of twenty five degree Celsius

Abstract

In this paper, a simulation by MATLAB code lines has been done for modeling of three types of mono-crystalline silicon photovoltaic modules by using single diode diode models. The three types of photovoltaic modules are DelSolar D6M195B2A, EPOLLY ep125M/72-195W and LDK 195 MC. The MATLAB simulation has been done by using the data provided by the commercial datasheets. In this paper, three types of photovoltaic modules have been modeled by MATLAB simulation at diverse values of solar irradiations (G) whilst temperature (T) equal to 25°C. A current-voltage (I-V) characteristics curves with regard to photovoltaic modules have been plotted by using MATLAB simulation at different values of G are 100, 400, 700 and 1000 W/m2, whilst T of twenty five degree Celsius. It has been noted from simulation results that during the changing of values of G for three photovoltaic modules leads to change the values of short circuit current (Ish) for each photovoltaic module. The simulation results of modeling of EPOLLY ep125M/72-195W photovoltaic module have been presented that the changing of values of G leads to small changing of values of Ish. Whereas, the simulation results of modeling of DelSolar D6M195B2A and LDK 195 MC photovoltaic module have been presented that the changing of values of G leads to changing of values of Ish, and that changing is bigger than case of EPOLLY ep125M/72-195W photovoltaic module. It has been concluded that EPOLLY ep125M/72-195W photovoltaic module is more suitable to be used during the regions that have frequently changing of values of G than using DelSolar D6M195B2A and LDK 195 MC photovoltaic module.
