Influence of parametric variation in extraction of MPP from solar PV modules

Solar Photovoltaic (PV) generation is contributing a major role in green energy production worldwide to substitute the conventional generating sources. However, the maximum power generation of PV modules gets affected due to certain environmental conditions and internal parameters that result in the reduction of maximum power point (MPP) of the PV module. In this paper, the effect of environmental conditions and internal parasitic elements of PV modules on power generation is studied. The analysis is done in MATLAB/Simulink environment that includes the variation of irradiance, temperature, series resistance, shunt resistance, ideal factor and partial shading condition. The MPP of the system is studied under the above-mentioned conditions using a 50W PV module. From the results, it is observed that the power generation of the PV modules strongly depends on these factors.
