Abstract

In order to improve the utilization rate of solar energy, A STC89C52 SCM to control the core of solar panel automatic tracking system is designed in this paper. It adopts the method of photoelectric tracking and sun angle tracking. The system judges sunny or cloudy by the weather detection circuit. When it is sunny day, the system uses the photoelectric sensor to gather the light intensity deviation to control the stepper motor to realize the photoelectric tracking. When it is cloudy day, the system can calculate the local solar altitude angle and azimuth angle by collecting the information of the clock chip, and the single chip microcomputer can drive the stepper motor through the instruction to realize the sun angle tracking. The experimental results show that the solar tracking system can track the sun in different weather conditions, and the energy receiving efficiency is improved obviously.
