Raising the tracking accuracy and stability of solar tracking system. It is one of the methods to improve the efficiency of solar energy utilization and reduce the cost. Therefore,the hybrid control solar tracking system with programmable control and light control is proposed. Making the wall has a certain angle and increasing the shading pate width to improve the stability and the deviation of light sensitivity by developing the photoelectric sense. The maximum deviation of the incident light is 0.105 mm.The experimental results show that this tracking device could improve the tracking precision and realize the solar energy absorption and utilization rate and automatic tracking throughout the day by making the solar lay beam down on the receiver vertically. Also,through the error analysis method,the absolute tracking error between measured data and theoretical data is controlled within ±0.1 degrees,it is more accurate than the existing tracking control device,which verified the device meets the requirements of stability,reliability,high precision,strong anti-interference ability and so on.
