Electricity plays a key role now in our daily lives but the energy sources of electric power has been used in abundance and so researchers were compelled to find an alternate source of power leading to the discovery of solar energy. Solar energy is rapidly employed as an important means of expanding renewable energy resources. Solar energy is inexhaustible and eco-friendly and can be converted into electricity using photovoltaic panels especially in the high solar illumination areas. These panels can be used in a fixed form or used in a solar tracking system employing single axis as well as dual axis. In the fixed configuration, efficiency is lower since the panels will be tilted in a particular angle whereas in the tracking system solar panels are made to move either in single axis or dual axis. In a single axis system the panel is moved in an
east to west direction with respect to the sun and it has better efficiency than panels in fixed form . This work present sun tracking system with single axi control. Obour Institute solar system is used for the experiment verification of this research. The recorded Efficiency improvement reaches around 20% higher than fixed system.
