Estimation of optimum tilt Angle for Solar Panel

SEEE DIGIBOOK ON ENGINEERING & TECHNOLOGY, VOL. 01, FEB 2018 PP.(174-177)
Abstract– The performance of photovoltaic (PV) solar module is affected by its tilt angle. Since the sun is higher in the summer and lowers in the winter, it is possible to capture more energy during the whole year by adjusting the tilt of the panels according to the season. Solar panels should always face true south if the location is in the northern hemisphere, or true north if the location is in the southern hemisphere. India lies in northern hemisphere hence the solar panel must be mounted in the southern hemisphere and adjusting the tilt angle twice a year gives a meaningful boost in energy. The tilt angle can be determined by geographic factor method, clearness index method, declination angle method, experimental method.
Index Terms – Solar radiation, tilt angle, latitude, geographic factor, clearness index, declination angle.
