[0002] Photovoltaic power generation is a new type of power generation device that uses inexhaustible solar energy to convert it into electricity for industrial and agricultural production and daily life. It can maximize energy conservation and emission reduction and is an important part of low-carbon life. At present, photovoltaic power generation uses photovoltaic panels to receive solar energy and convert it into electrical energy for external output. The larger the area, the higher the power generation efficiency, so it is inevitable to occupy a large amount of land resources. The organic combination of agricultural planting and photovoltaic power generation can not only use the vast rural planting land for photovoltaic power generation, thereby transmitting industrial and agricultural production and daily electricity, but also ensure the normal growth of crops, ecological mutual feedback, win-win benefits, and promote the development of agriculture and photovoltaic industries. The support devices for photovoltaic power generation in related technologies are mostly fixed supports, or angle-changing devices that are only set to receive solar energy. While completing photovoltaic power generation, they cannot effectively take into account the natural precipitation replenishment required for crop growth, and cannot ensure the environmental humidity required by shade-loving plants.
