| Abstract: | In order to improve the efficiency of solar photovoltaic power generation, this paper design a high precision automatic solar tracking system. The system mainly uses the complementary combination manner of the signal acquisition with coarse and fine tune to achieve a wide range, high precision, all-weather automatic tracking of the sunlight, and the tracking accuracy has been up to 0. 1° solid angle. The experimental results show that the system is easy to operate and has high tracking accuracy;and the average output power was 30. 7% higher than that of fixed photovoltaic power generation system. |
