Automatic Sun Tracking for the Enhancement of Efficiency of Solar Energy System

Energy is the prime component for the development of a nation. Enormous amount of fossil fuels, viz. coal, gas, oil, etc. are extracted, converted, distributed and consumed by the society on daily basis for various activities. The limited stock of fossil fuels and its end result as global warming forced scientists to harness energy from nonconventional resources. Renewable energy, such as solar, wind, geothermal, ocean tidal waves are the best proven sources of energy. Solar energy is one of the most abundant and cheap resources among these. Solar energy is converted into electrical energy with the help of photovoltaic solar panels. Solar energy is maximized when the sunrays fall perpendicular on the panel. The rigid fixed type conventional solar panels have restriction to receive maximum sunrays because of changing angle of incidence. Automatic sun tracking system is the solution to harness maximum solar energy by facing the sun whole day.
