ABSTRACT

 The demand for energy is always on the increase in every nation. Infact it's importance cannot be overemphasized because of it's useful application in the generation of electricity. Fossil fuels have played a huge part in this course but we cannot overlook it's negative impact in our environment such as pollution thereby bringing global warming and greenhouse effect. Having considered this, the solar tracking device aims to resolve this problem by harnessing and utilizing solar energy in it's cleanest possible way. This device is designed in such a way as to track the movement of the sun throughout the day to ensure that energy from the sun is fully utilized. In order to maximize the conversion from solar to electrical energy, the solar panels have to be positioned perpendicular to the sun. Thus the tracking ofthe sun’s location and positioning ofthe solar panel are important. The goal of this project is to design an automatic tracking system, which can locate position ofthe sun. The tracking system will move the solar panel so that it is positioned perpendicular to the sun for maximum energy conversion at all time. Photoresistors will be used as sensors in this system. The system will consist of light sensing system, microcontroller, gear motor system, and a solar panel. Our system will output up to 40% more energy than solar panels without tracking systems.
