Solar energy has become an important part of mankind’s energy use and has been continuously developed. Moreover, solar energy is a kind of renewable energy and has become more and more popular, but how to improve the conversion efficiency of solar energy is the key to the rational and effective use of solar energy. In order to solve this problem, the solar photovoltaic tracking system came into being. The photovoltaic tracking system tracks the sun’s movement in real time and directs sunlight to the photovoltaic array, thereby increasing the amount of solar radiation received by the photovoltaic array and improving the overall power generation of the solar photovoltaic power generation system. the amount. Through on-site operating data statistics, the dual-axis tracking system can increase power generation by more than 35%. The dual-axis tracking system adopts active tracking. By driving two stepping motors, the photovoltaic cells can automatically track the sun in the horizontal and vertical directions at the same time, so as to ensure that the surface of the light board is always perpendicular to the sun’s rays and receive the maximum amount of solar energy. The system can rotate around one axis in the east-west direction (also known as azimuth tracking), and at the same time, adjust the tilt angle along the other axis (also known as altitude tracking), so that the photovoltaic modules are always facing the sun to improve light utilization. The mechanical structure of the reliable dual-axis tracking system can effectively improve the operating quality of the entire photovoltaic grid-connected power generation system.
