[0002] Photovoltaic power generation, with its advantages of being green, economical, and inexhaustible, has become one of the fastest-growing forms of clean energy utilization.
[0003] As photovoltaic (PV) power generation accounts for an increasingly larger share of installed power capacity, statistics show that surface dust pollution has become a significant factor affecting the power generation of PV power plants. Dust accumulation on the surface of solar panels restricts power generation efficiency. Therefore, ensuring the cleanliness of the module surfaces and reducing dust obstruction during power plant operation and maintenance is an important method to improve the output power of PV modules. Since solar panels are mostly installed in sparsely populated mountainous or desert areas, where water and manpower are scarce, the cleaning of solar panels presents a challenge.
[0004] We plan to improve the cleaning efficiency of solar panels and thus increase the power generation efficiency of photovoltaic power generation by researching cleaning technologies for solar panels. To this end, we have designed a solar panel cleaning machine that mainly uses a combination of blowing and suction to clean solar panels, aiming to work in water-scarce areas and areas that are difficult to clean manually. This will improve power generation efficiency while reducing water consumption and labor costs. Utility Model Content
