Problems solved by technology

[0002] Solar energy is a kind of renewable energy. Human beings have a long history of using solar energy, and it has been widely used up to now. The most common one is the solar photovoltaic power generation system. The solar photovoltaic panel in the solar photovoltaic power generation system is a kind of The power generation device that will generate direct current is composed of solid photovoltaic cells almost entirely made of semiconductor materials (such as silicon), which can convert the sun's radiation into electrical energy. The main factors affecting solar energy collection are the intensity of sunlight, light Irradiation angle, light receiving area, etc., then the control system must consider these factors in order to better convert solar energy into electrical energy. Obviously, the role of control is very important, and the existing control has made great technological progress in solar ray tracing. However, there are still problems such as insufficient accuracy and insufficient real-time performance, and in order to collect more solar energy, most of the time, the centralized form of solar photovoltaic panel arrays is adopted. The centralized array form can collect more energy faster, but in practice tracking When the sun is shining, the array needs to adjust the angle, and it is inevitable that the arrays will block each other during the adjustment process.
