Design, Analysis and Working of a Sun Tracking Photovoltaic System

As the power requirements for microelectronics It is estimated that the global energy requirement is 15 terawatts and this value expected to increase enormously in the future with the increase in population in developing countries and with the higher standards of living that these countries strive for, and traditional methods of electricity and energy generation such as fossil fuels are merely a tiny blip compared to this number. However, solar power reaching land comes up to a staggering 20,000 terawatts. And, even if you have all kinds of practical limitations, you could probably easily get hundreds of terawatts out of solar, if you had to. For collecting solar energy, if fixed solar panels are used, we get an efficiency of only about 22% (in best cases) and this too, is limited even further as these solar panels directly face the sun for just a small period during the course of a day. To improve this number, a sun tracking solar panel has been designed. The circuit comprises of ATMega328, two servo motors and four Light dependent Resistors. A traditional fixed solar panel, which is tilted at an angle between 18 and 25 degrees, is then compared to the sun-tracking model and analysis have been conducted.
