Therefore, the generating efficiency of the photovoltaic module generally declines year by year, and the generating efficiency can decline by more than 10% in two or three years, and can decline by more than 20% in 7 or 8 years. Even decline of more than 40% under extreme use conditions.
The decline of the power of the photovoltaic module arouses great attention of the industry, and a great deal of research is carried out on the cleaning process, the cleaning automation equipment and the cleaning liquid formula of the photovoltaic module, and a plurality of patents are also applied. The Beijing Shijing New energy science and technology Limited company applies for a photovoltaic power station cleaning vehicle with the publication number of CN205868905U and an adjusting arm thereof, and aims to provide a cleaning vehicle with the advantages of large adjusting range and good effect on cleaning various solar components and an adjusting arm thereof; shanghai' an Xuan automation technology limited company applies for a plane solar module cleaning device with the publication number of CN205949358U, and the plane solar module cleaning device comprises a cleaning unit, a battery unit and a guide rail; the combined fertilizer and culture win new energy science and technology company applies for a photovoltaic module cleaning solution with the publication number of CN107488521A, which comprises the following raw materials: phosphoric acid, oxalic acid, fluosilicic acid, malic acid, linear alkyl benzene sodium sulfonate and water; the cleaning solution can be obtained by uniformly mixing the raw materials at normal temperature and then stirring for 20-30 min.

The method is effective, the power generation efficiency of the photovoltaic module is also really and greatly improved, but as the time is prolonged, the light transmittance of the cover plate glass is reduced year by year and the power generation power of the photovoltaic module is reduced year by year due to the fact that the photovoltaic glass of the upper cover plate of the photovoltaic module is polluted by various kinds and the weather resistance of the photovoltaic glass is poor. 8. In 9 years, the decline is already serious, namely the decline of the power generation power reaches 20-30% and the decline of the power generation power even reaches more than 40%, regardless of the film coating component or the non-film coating component, and the power generation efficiency is greatly influenced.
The traditional cleaning method is only physical cleaning, and newly fallen dust on the surface of the cleaning component is cleaned, so the effect is limited; no way to remove bird droppings on the assembly; for cover plate glass of which the components are mildewed due to high temperature and high humidity, no method is available for removing white spots and crystal specks on the surface; in a specific environment, for example, a layer of iron oxide dirt exists on the surface of a component near a steel mill, and a layer of vulcanized rubber exists on the surface of a component near a rubber mill, so that the component is not easy to clean; frequent brushing can physically damage the membrane surface and reduce the power generation efficiency of the module.
