The main reasons for the influence are as follows:
firstly, the light transmittance is influenced by the dirt on the surface, and the radiation quantity received by the surface of the component is further influenced;
secondly, the dirty on subassembly surface can form the shadow because the distance with the battery piece is very close to at the local hot spot effect that forms of photovoltaic module, and then reduce the generating efficiency of subassembly, even burn out the subassembly, consequently regularly wash photovoltaic module very necessary, the economic benefits output that brings simultaneously also is very considerable.
At present, the traditional method for removing dust (dirt) of a large-scale solar photovoltaic power station mainly comprises the following steps:
firstly, cleaning by spraying with a water truck high-pressure water gun;
secondly, manually wiping.
The first method has the disadvantage of large water waste, and in cold regions, the cleaning is affected by seasonal temperature. The second method has the disadvantages that more manpower and material resources are required to be invested, and meanwhile, certain potential safety hazards exist in manual operation.

(2) a mechanical transmission part is arranged, so that faults are easy to occur;
(3) the surface of the photovoltaic module is easily scratched;
(4) the cleaning parts need to be cleaned or replaced regularly, so that the cost investment is increased;
2. the surface of the component is dedusted by water (rainwater) flushing and spraying, and the method has the disadvantages that the cleaning medium is limited to water (rainwater) and the operation is limited by the environmental temperature;
3. the method combines the scraping, brushing, roller and the like with a water system, and has the disadvantages of excessively complex structure, high investment and poor popularization. Among the three technologies, under suitable conditions, the cost performance of dust removal by only depending on water is highest from the viewpoint of dust removal effect and investment.
At present, on photovoltaic module washs, there is not the very high cleaning equipment of degree of automation temporarily, and domestic mainstream mode still relies on manual cleaning, and not only inefficiency, the cleaning performance is unsatisfactory, still can not realize the cyclic utilization of water resource, and the cleaning cost is higher. In recent years, in China, a great number of beneficial attempts are made on how to improve a component cleaning mode, such as a high-pressure gas dust blowing method, a nano coating dust prevention method and the like, but the new modes all have some problems in cost and effect, in addition, an important item of maintenance work of a photovoltaic component also comprises fire fighting work, at present, fire fighting equipment with high automation degree is not available, the fire fighting equipment is independent of cleaning equipment and is not integrated, and therefore equipment with moderate cost, convenience and quickness in operation and obvious effect for automatic cleaning and fire fighting of the photovoltaic component is urgently needed.
