Description

Technical Field

[0002] Photovoltaic panels are devices that use the photoelectric effect to directly convert solar energy into electrical energy. Photovoltaic panels are the core component of solar power generation systems. Their main function is to convert sunlight into direct current electricity, which is then used by electrical equipment or converted into alternating current through an inverter. Cleaning the surface of photovoltaic panels is essential to maintaining their high efficiency in converting solar energy. Cleaning the surface of photovoltaic panels can help maximize their ability to absorb solar energy and improve the efficiency of solar cells. Photovoltaic panels need to be cleaned regularly, especially in dry and rainless areas or in dusty environments, where more frequent cleaning is necessary. Usually, a soft, non-abrasive cloth or sponge is used to clean them with warm water. For stubborn dirt, warm water and a small amount of neutral detergent can be used to gently wipe them. Due to the characteristics of photovoltaic panels, high-pressure water guns should be avoided or water should be sprayed directly onto the surface of photovoltaic panels to prevent damage to the sealing and electrical components of photovoltaic panel components. In the prior art, photovoltaic panel surface cleaning is mainly carried out manually, which is labor-intensive, dangerous, and inefficient. Summary of the invention
