Tilt angle optimization for maximization of solar irradiance for a Photo- Voltaic panel for Chandil, Jharkhand

Abstract

Being positioned over subtropical belt, India has ample amount of sunlight throughout the year. Thus, energy from day light is one of the most promising sources to fill the demand-supply gap of power and this can be done effortlessly by PV technology. In this work we have tried to explore the possibilities to achieve maximum benefit of day light energy by adjusting the PV system in accordance with the sun’s position. This can be done by placing the panel over inclined axis as compared to horizontal. The most effective inclination has been computed for Chandil, located in the state of Jharkhand, on monthly basis throughout the year. The orientation was changed from 0°-90° with lap of 0.05° in order to compute maximum radiation. It has been concluded that the average annual tilt in the axis of panel should be 22.454° which increases the energy by utmost 13%.
