Photovoltaic panel cleaning robot hair brushes are solar photovoltaic cleaning brushes. Solar cleaning brushes can be designed into spiral brush rollers, tufted brush rollers, disc brushes and other shapes according to the cleaning equipment. Photovoltaic solar panels mainly generate electricity by absorbing solar energy and converting them into electrical energy. Cleaning as required can ensure the cleanliness of the surface of the photovoltaic panel, which is beneficial to absorb as much sunlight as possible, thereby ensuring the power generation; if the components accumulate dust for a long time, not only will it be lost If the power generation is serious, it will also produce hot spot effect, resulting in short life and even damage to the components; therefore, it is necessary to always pay attention to the cleanliness of the components, and clean them appropriately to ensure the power generation.
