Research on cleaning scheme of photovoltaic power plant based on pollutant composition analysis

Abstract

Solar photovoltaic (PV) modules, as an important component of the photovoltaic conversion process within a PV system, are closely related to the efficiency and service life of the PV system’s overall work performance. Dust in the atmosphere is affected by rainfall, electrostatic forces, van der Waals forces and gravity, and will gather together and settle on the surface of the PV module to form dust accumulation, which reduces the amount of radiation and light energy absorption. Therefore, it is really necessary to carry out the research on the pollutant composition and treatment measures program of the surface pollution index of PV modules.
