Background
Solar photovoltaic systems, also known as photovoltaics, photovoltaic for short, refer to facilities that utilize the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electrical energy. The core of a photovoltaic installation is a solar panel. The semiconductor materials used for power generation are mainly: monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and the like. Since the application of renewable energy is actively promoted in various countries in recent years, the development of the photovoltaic industry is very rapid.
As of 2010, solar photovoltaics were put into use in hundreds of countries around the world. Although the power generation capacity of the photovoltaic power generation system still accounts for a small part of the total amount of human electricity, the photovoltaic power generation amount of the power grid is increased at a rate of 60% per year from 2004. By 2009, the total power generation capacity has reached 21GW, which is the fastest energy currently developing. It is estimated that without grid tied photovoltaic systems, the capacity is also about 3 to 4 GW.
The photovoltaic system can be installed on the ground surface in a large scale to form a photovoltaic power station, and can also be arranged on the roof or the outer wall of a building to form photovoltaic building integration.
Since the advent of solar cells, the use of materials, the continuing advances in technology, and the mature growth of the manufacturing industry have driven the price of photovoltaic systems to become cheaper. Moreover, many countries invest a lot of research and development expenses to promote the photovoltaic conversion efficiency and give financial subsidies to manufacturing enterprises. More importantly, the wide application of photovoltaic in various countries is greatly promoted by policies such as online electricity price subsidy policy and renewable energy ratio standard.
Solar panels (also called photovoltaic panels) are generally arranged in large quantities at a certain angle in flat and unobstructed areas such as plain areas of inner Mongolia areas in order to receive light for as long as possible to achieve maximum conversion efficiency. The conversion efficiency is related to illumination and the cleanliness of the photovoltaic panel, in practical application, the dirty matter on the surface of the solar photovoltaic panel can reduce the light transmittance of the surface of the solar photovoltaic panel, when the solar photovoltaic panel works normally, the dirty matter can absorb part of energy and consume the energy in the form of heat, the influence is generated on the surface of the photovoltaic panel, and the surface of the photovoltaic panel can be damaged seriously, so that a hot spot effect is generated (the hot spot effect of the photovoltaic module refers to the phenomenon that under a certain condition, a shielded solar cell module in a series branch serves as a load, the energy generated by other illuminated solar cell modules is consumed, and the shielded solar cell module can generate heat at the moment, the damage caused by the hot spot effect of the photovoltaic module is great, the shielded photovoltaic module can consume part of or all of the energy generated by the illuminated photovoltaic module, and the output power is reduced, severe will permanently damage the solar cell module or even burn out the module).
In addition, as the grassland weather (inner Mongolia region) is changed frequently, rain in a clear day is mostly rain after sand dust, so that the surface of the photovoltaic panel is dirty after the weather of sand dust, rain and snow, the surface of the photovoltaic panel cannot grab rain, the weather is clear after rain, the generated energy is sufficient in sunlight, the generated energy of the photovoltaic equipment is influenced considerably, and the economic loss is huge. Secondly, for the wind and light power station with the best of the Huanengming, a large amount of manpower and material resources are consumed for cleaning the photovoltaic panel every year, and the money can reach hundreds of thousands to hundreds of thousands of RMB.
