Description

technical field [0001] The invention relates to a design method of an underwater submerged photovoltaic power generation system, belonging to the technical field of photovoltaic power generation. Background technique [0002] At present, a floating photovoltaic power generation system has appeared on the water surface. Because the water surface is cheaper than the land, its development momentum is rapid. However, with the vigorous development of water surface photovoltaics, it is found that there are many problems, especially in the fields of environmental protection and aquaculture. protrude. For example, the floating photovoltaic power generation system uses the buoyancy tank floating on the water surface as the buoyancy carrier, but the buoyancy tank floating on the water surface occupies a large amount of water surface, reduces the contact area between the water surface and the air, and has a negative effect on the oxygen content and temperature emission in the water.

[0002] At present, a floating photovoltaic power generation system has appeared on the water surface. Because the water surface is cheaper than the land, its development momentum is rapid.

For example, the floating photovoltaic power generation system uses the buoyancy tank floating on the water surface as the buoyancy carrier, but the buoyancy tank floating on the water surface occupies a large amount of water surface, reduces the contact area between the water surface and the air, and has a negative effect on the oxygen content and temperature emission in the water. In addition, the surface of photovoltaic modules of floating photovoltaic power plants is prone to dust accumulation, and excessive dust accumulation will affect the photoelectric conversion efficiency of photovoltaic modules
