Abstract:
Solar panel has been used increasingly in recent years to convert solar energy to electrical energy. The solar
panel can be used either as a stand-alone system or as a large solar system that is connected to the electricity grids.
The earth receives 84 Terawatts of power and our world consumes about 12 Terawatts of power per day. This project are
trying to consume more energy from the sun using solar panel. 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 of the sun’s
location and positioning of the solar panel are important. The goal of this project is to design an automatic
tracking system, which can locate position of the 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.
This system will output up to 40% more energy than solar panels without tracking systems.
