Therefore, the solar power generation technology is comprehensively researched and developed, but due to the defects of weak solar intensity, poor continuity, instability and the like, the efficiency of power generation by using solar energy is low and the power generation is unstable. In order to solve the defects of weak strength, poor continuity and instability of the existing solar photovoltaic, the automatic tracking of the sun is realized by most of the existing solutions. The solar photovoltaic power generation panel can automatically track, the effect of the solar photovoltaic power generation panel is similar to the effect of a sunflower, and the deflection angle of the solar cell is correspondingly and automatically adjusted along with the change of the position of the sun, so that the tracking of the sun is realized. The automatic sun tracking technology can enable sunlight to vertically irradiate on the solar cell panel, and solar energy resources are better and more fully utilized. According to related researches, the flat-plate solar power generation array can improve the efficiency by 33% compared with the original fixed mode when the sun is automatically tracked.
For example, patent No. cn201610906044.x discloses a solar tracking device for photovoltaic power generation.
