Abstract:

The paper presents a dualmode solar tracking controller based on C8051f061 for better accuracy. The system combines the visual solar movement trajectory with the high accuracy tracking of four quadrant photoelectric detector. After the solar azimuth and altitude angle are calculated, the cell panel is adjusted vertical to the sunlight by driving the step motors that controls the azimuth and altitude to achieve high tracking precision, thus a higher utilization of solar energy. The experiment results show that the solar tracking controller can achieve high tracking accuracy.
