JEE_V9_N3_RP3 Vivekanand Rai Kishan Bhushan Sahay Journal on Electrical Engineering 2230 – 7176 9 3 12 19 Mathematical Model, Maximum Power, PV Cell, PV Module, Solar Irradiation, Shunt Resistance This paper presents an efficient mathematical and simulation model for a solar photovoltaic system. This is an analysis on the characteristics of photovoltaic (PV) Cell under various weather conditions. Considerably, the PV cells are nonlinear in nature, whose characteristics and the maximum power point varies with irradiance and temperature. It focuses on the effect of variation in series and shunt resistances. The model is proposed to study the expected environmental issues on the solar power generation. By the help of this model, a study of large PV system or solar energy system can be done easily. This model elaborates various effects of parameter variation on the P-V and I-V characteristics of the PV module. This model was developed with the help of Simulink software and can be utilised for various study and research purposes. January - March 2016 Copyright © 2016 i-manager publications.
