To sustain life in earth we need considerable amount of energy. For our body it is given by food we eat but we also need energy for machines and equipment for them to work. Since non-renewable source of energy is exhaustible in nature so nowadays we move towards renewable source of energy. One of the major sources of renewable energy is sun. Today we are using only a small amount of solar energy by using solar cells. These solar cells are placed at fixed position so amount is limited. To increase the amount of energy we receive we use solar tracker. Solar tracker is the device used to follow the sun. In this paper we deal with dual axis solar tracker with real time tracking technology. By this method we can increase the solar energy production up to 45%.
