Study on the Influence of Ash Accumulation on Radiation Quantity of Photovoltaic Modules.

As an important component of the photoelectric conversion process in the photovoltaic system, the working efficiency and service life of solar photovoltaic modules are closely related to the overall working performance of the photovoltaic system. Particle settlement problems caused by air pollution and abnormal weather in Northwest China increase the amount of ash on the surface area of photovoltaic modules, reducing the amount of radiation and light energy absorption. Therefore, it is necessary to carry out photovoltaic module ash accumulation experiments and radiation intensity characteristic research.
