SOLAR TRAKING SYSTEM

                                    Solar energy systems have emerged as a viable source of renewable energy over the past two or three decades and sun is the great power source and a great renewable energy source. Solar power is an alternative technology that will hopefully lead us away from our petroleum dependent energy sources. Fossil fuels are a relatively short-term energy source. Studies suggest that the rate at which fossil fuels are consumed today, there are high chances that they will deplete by the end of this century. For a long time, it has been thought that atomic energy would be a solution for the growing energy problem, but in recent times solar energy has proved to be an efficient, more secure and safe way of providing energy to all type of systems. Also one third of the world population do not have access to electricity and are not connected to the national grid, one solution to this problem is renewable energy in the form of photovoltaic (PV) systems.

To make solar energy more viable, the efficiency of solar array systems must be maximized. In order to ensure maximum power output from PV cells, the sunlight’s angle of incidence needs to be constantly perpendicular to the solar panel. This requires constant tracking of the sun’s apparent daytime motion, and hence develops an automated sun tracking system which carries the solar panel and positions it in such a way that direct sunlight is always focused on the PV cells. So we get the systems more efficient and cost effective.

Solar tracking system plays a major role in overall solar energy optimization. And this system is a feasible method of maximizing the energy received from solar radiation.
