Optimization of tilt angle for installation of solar photovoltaic system for six sites in India

The maximum incident solar radiation is important for power generation which can be achieved by optimization of solar photovoltaic system tilt angle. In this paper optimum tilt angle is calculated for six sites in India. It was found that the optimum tilt angle is 0° in April, May, June, July and August for six different sites and it is maximum in December. The two new correlation of optimum tilt angle in terms of declination angle is developed which is important for installation of solar photovoltaic system in India.
