Abstract : solar energy is an abundant source of energy available in almost all parts of the world. It provides both heat and light energy. Light energy is converted to electricity by photovoltaic module. The energy conversion is maximum only when the solar panel is kept perpendicular to the sun rays. For this, solar position over the sky is calculated by considering the varying altitude and azimuth angle of the sun at any time of a location and the results of these solar angles are observed from the solar tracking program developed in MATLAB (.m file) and the step angle is computed for both the axes according to which the solar panel is to be tilted automatically to track the sun and kept perpendicular to the sun rays to make the incident angle almost zero. This is used to design a solar tracking system on both the axes and thereby increasing the performance compared to a fixed tilt photovoltaic module.
