Abstract: Solar Photovoltaic system is a power system designed to supply usable solar power by means of photovoltaics. The total power generated by a photovoltaic panel depends on light intensity falling over the surface. The variation of light intensity plays a predominant role in solar power generation. The effect of light intensity on a photovoltaic power generation could be extrapolated using PSIM software. The result shows that if the light concentration on a solar cell increases the power output also increases.

Keywords: P-V cell, P-V array, Irradiation, Pyranometer, I-V and P-V characteristics.
