Calculation of Sun Position and Tracking the Path of Sun for a Particular Geographical Location

Solar energy is one of the freely available renewable sources of energy and abundant in almost every part of the world. It is the most fundamental among the alternative sources of energy. With a view to collect energy from the sun, it is necessary to predict the sun position relative to the collection device. In this paper, an attempt has been taken to track the exact location of the sun for any geographical location of the earth. MATLAB software has been used to track the sun path and corresponding information such as sunrise and sunset. Here, the location of Silchar in the state of Assam of north-eastern India has been considered Keywords— Altitude angle, azimuth angle, latitude, solar energy, solar time, standard meridian.
