A Solar Automatic Tracking System Design Based on FPGA

In order to improve the solar energy utilization, in the respect of technology, we should perfect solar tracking devices, realization of the sunlight is always vertical to the solar panels. This paper is to design a kind of solar automatic tracking system. Design adopts the traditional photoelectric tracking method, with the FPGA as the core, and by using the methods of scheduled monitoring, achieve precise control of stepping motor, thereby promoting the solar panels rotate remains vertical to the sun, which can effectively improve the efficiency of solar power systems.
