In 2018, the national renewable energy power generation amount reaches 1.87 trillion kilowatt hours, the proportion of the renewable energy power generation amount to the total power generation amount is 26.7%, wherein the photovoltaic power generation amount reaches 1775 trillion kilowatt hours and is increased by 50% on a same basis.
in photovoltaic power generation, dust pollution due to lack of active and effective cleaning greatly reduces the power generation capacity of the power station, which is expected to be at least 25% or more per year, and thus brings huge direct economic losses. Firstly, the dust shields the light reaching the photovoltaic module; secondly, because some dust with strong acid-base property erodes the surface of the solar photovoltaic panel, the light transmittance of the panel glass is reduced; thirdly, the dust can affect the heat dissipation of the surface of the photovoltaic module, which leads to the reduction of the photoelectric conversion efficiency.
It is understood that most solar power plants in China are more or less plagued by this "dust" problem. Data show that the generated energy of the photovoltaic industry in 2018 exceeds 1775 hundred million kilowatt hours, and the data also mean that the conservative estimation of the loss of the generated energy caused by dust in the solar power generation industry in 2018 is as high as 444 million kilowatt hours, and the lost electricity charge is more than 430 million yuan.
