Modeling of solar photovoltaic module and study parameter variation effect using MATLAB/Simulink

Solar Photovoltaic cell is the smallest unit of solar photovoltaic power system, it converts light energy in to electrical energy. The phenomenon of this conversion of light energy into electrical energy is termed as Photovoltaic effect. The aim of this study is to develop a model for photovoltaic module based on mathematical expression. The conventional single diode model for solar cell with series and shunt resistance is used for illustration. The effect of change in environmental condition like irradiance and temperature on output of photovoltaic module is shown, the effect of physical parameter variation such as shunt and series resistance is also consider. The characteristic of proposed model is compared with the reference photovoltaic module. The 250 watt photovoltaic module manufactured by Tata solar power is used as reference. The large solar array system can be modeled and simulate using this model. Simulation was performed at any and all step using MATLAB/ Simulink software.
