Non renewable energy sources like fossil fuels are soon being depleted and in near future we will be faced with its extinction. Alternative energy sources which are renewable and are available in abundant quantity are required. Sun's insulation fits both the criteria. Hence there are emerging technologies focused on harvesting solar energy. Be it photovoltaic panels or concentrating panels, they aren’t most efficient if they are installed in a fixed position. Due to earth's spin we see sun in different positions throughout the day, hence light tracker is used along with mechanisms which orient a solar panel or a concentrating panel throughout the day. Designing and fabricating a Dualaxis solar tracker one needs to have a proper grasp of Basic electronics, control systems and mechanical mechanisms
