Research and design of control system of the solar panel tracking

This paper presents a design of the maximum solar power auto-tracking control system based on Single Chip Microcomputer (SCM) utilizing photoelectric detection tracking method which accurately tracks the orbital movement of the sun. The system comprises seven main parts these are SCM, Photoelectric-detection circuit, Global Position System (GPS) module, Voltage/current-detection circuit, Communication module, Clock circuit and Driver module. The tracking is realized with the aid of the concept known as photoelectric tracking which employs the perturbation and observation algorithm for accurately locating the position of the sun. This method ensures maximum harnessing of solar energy as well as high reliability and efficiency in solar energy conversion. The operation of the system is very accurate, reliable and has a simple structure.
