Design and Performance Analysis of 11.2 kW PV System under Variable Field Conditions

Photovoltaic (PV) generating systems are widely used for renewable power generation all over the world. The PV system produces the non-linear characteristics curves under the normal operating conditions. However, the PV system faces tremendous challenges while delivering maximum power in the field conditions. The challenges involve variation of solar insolation, temperature rise and variation in series and shunt resistance. During these conditions, the characteristics curve of the system changes resulting decrease in power output. In this paper, a mathematical modeling of 280W PV module is carried out in MATLAB/Simulink environment. An 11.2 kW PV system is modeled using a number of 280W PV modules. The 11.2 kW system has been tested for its behavioral study under various environmental and field conditions. The study shows that the output power of the system varies with respect to the variation of environmental and field condition.
