Go back to store the correct data when can be real when it is fine while measuring , dispel the accumulation error produced because of seasonal variation , position on can when being automatically fine day of quoting at overcast day , reach the anticipated performance index , it is high to control the precision , have extensive application potentiality. Realize following the trail of the result of the sun , achieve the goal of improving efficiency of generating electricity.This system not merely can automatically adjust the solar battery orientation according to the sunlight direction, with simple structure and low costs; it can memorize and correct automatically the coordinate position of different time in the process of tracing as well, without manual operation, especially for the cases of complicated weather and nobody guarding. Solar automatic tracking system according to the local latitude and longitude of automatic detection day and night, and the application of solar radiation and brightness of the environment compared to the automatic tracking system makes the accuracy, reliability, in the course of sunny real-time detection to keep the correct time and angle data, due to seasonal changes and eliminate the accumulated error. On cloudy days when the automatic rotation through comparison to the previous sunny location. Even if the weather changes in the complicated circumstances, the system can also work to enhance the efficiency of the utilization of solar energy. Abstract: the sun follows; the photoelectricity is measured; makes a reservation automatically; One-chip computer,designs
