This system offsets the E arth s rotation by them ovem en t of polar axis to ach ieve trajectory tracking of the sun. It comb ines the excellences of both clock con trol and sensor control. As the coarse tracking, clock control tracks the theoretical position of the sun to prevent the large deviation of the light. As the finetun ing, sensor control tracks the physical location of the sun. The sun autotrackerm akes solar panel always verti cal to the sun at sunny day, and it can turn off the sensor control at cloudy day. The device reduces the cost, and has great practical value.
