摘要：
A novel solar tracking system with high-precision for concentrating photovoltaic cells was proposed and investigated in this study. The system structure, photoelectric sensor, tracking algorithm and tracking scheme were optimized to achieve high-precision solar tracking under all-weather conditions. In the novel design, the transmission system adopted a high-precision worm gear with a transmission ratio of 100:1 and an eccentric bushing. A four-quadrant silicon photocell was used to replace the conventional photosensor. The high-precision ENEA algorithm was employed to calculate the solar position. Moreover, an error correction algorithm was established based on the robot kinematics to eliminate the systematic errors caused by the initial position, pose of the tracking system, manufacturing and assembly inaccuracy. A hybrid tracking scheme combining both active and passive tracking strategies was used. A prototype tracking system was experimentally examined and the tracking accuracy can reach 0.188°. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
