Abstract

The invention provides a solar photovoltaic panel surface cleaning system and a cleaning method. The system is characterized in that the whole cleaning device is arranged on an unmanned aerial vehicle, an infrared camera and a visible light camera which are used for shooting are arranged on the unmanned aerial vehicle, a stain positioning system used for positioning is further arranged on the unmanned aerial vehicle, and meanwhile, a device for loading cleaning liquid and a device for loading carbon dioxide are arranged. Compared with an existing photovoltaic panel decontamination technology, the system adopts an environment-friendly stain cleaning agent, the surface of a solar photovoltaic panel is sprayed with the stain cleaning agent, meanwhile, a carbon dioxide snow decontamination technology is matched, so that residual stains are cleaned again without leaving water stains; and therefore, the problem of water shortage in regions such as deserts or gobi is solved.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic panel power generation, and relates to a method and system for cleaning the surface of a solar photovoltaic panel. Background technique [0002] With the advancement of technology in recent years, photovoltaic power generation has been widely used and developed rapidly due to its environmental protection and renewable advantages, and the cost per unit energy of existing solar power generation has dropped significantly to the level of thermal power generation. Because large-scale solar photovoltaic power stations are often distributed in sparsely populated areas such as open deserts and Gobi, solar photovoltaic panels are placed in exposed harsh environments for a long time, and their surfaces will be polluted by sandstorms, ice and snow, and bird droppings. The heat conversion rate is greatly reduced, and because the polluted part cannot work normally, the temperature is too high and bu...
