Problems solved by technology

Advantages: By spraying water on the surface of photovoltaic modules, the surface temperature of photovoltaic modules can be effectively reduced, and the power generation efficiency and power generation capacity of photovoltaic modules can be partially improved; however, the dust and dirt on the surface of photovoltaic modules cannot be cleaned thoroughly, and the invention is in After the upper surface of the photovoltaic module is sprayed with water, dust is more likely to stick to the upper surface of the photovoltaic module. The accumulation of dust and dirt will block the sunlight, resulting in a decrease in the power generation efficiency of the photovoltaic module

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a cooling, cleaning and efficiency-enhancing system for photovoltaic modules. Background technique [0002] At present, my country's new energy and renewable energy are developing very rapidly, especially the construction of photovoltaic power plants. Although my country started late, it has developed very fast and now has the world's largest photovoltaic power station. [0003] How to effectively improve the power generation efficiency and power generation capacity of photovoltaic power plants is an important topic of current research. In order to make the photovoltaic power station reach the initial design power generation after completion, it can only rely on refined operation and maintenance management to ensure the power generation. One of the main factors affecting the efficiency of photovoltaic power plants. The maximum power temperature coefficient...
