Some Analytical Studies on the Performance of Grid Connected Solar Photovoltaic System with Different Parameters

AbstractThis paper presents some analytical studies on the performance of grid connected solar photovoltaic system with different parameters in Rajasthan. The various factors that are considered for performance evaluation are: solar irradiation, ambience, tilt angle, orientation and shading. Rajasthan is rich in solar energy with varying ambience. Thus, due to change in climatic condition the PV system performance varies from place to place to a considerable extent. This influences the energy yield as well as economics of such system. In this paper a performance evaluation have been carried out for a 5 MWp crystalline silicon solar photovoltaic power plant in Rajasthan. As a part of the plant design, considerations have been taken in account on aesthetic, safety and cost aspects. The optimised annual energy yield of the 5 MWp is in the order of 8 GWh at a tilt angle of 22̊, average ambient temperature of 26̊Cand relative humidity (RH) of 60%. The minimum yield observed was about 7 GWhat 28̊ tilt angle, average ambient temperature of 20̊C and RH of 75%. These studies justified on the implementation of photovoltaic system in urban areas of developing countries where peak load demand is very high
