A Novel Method for Solar Tracking

Abstract:

A novel solar tracking method based on field programmable gate array (FPGA) is proposed to improve the photoelectric conversion rate of the solar cell unit area. In this method, the sun angle tracking is utilized to track, and tracking solar panels reach the altitude angle azimuth tracking position. Then four voltage signals of photo resistor sensors is used to compare the north-south direction and east-west direction respectively, in order to micro adjust the solar panels to getting same point voltage, enabling to achieve accurate sunlight tracking and positioning. Experimental results show that this method can accurately track the tracking the sun, and it has improving solar absorption efficiency of the solar tracking device.
