Abstract
The article provides the main reason for the pollution of solar modules and, consequently, a decrease in the efficiency of their work, in particular, dust pollution.Article describes the characteristics of dust, namely, its electrical properties depending on the source of origin, that is, the electric charge and electrical conductivity, which affect the adhesion of dust particles to the module surface, examples of the place of origin of various types of dust, their sizes, and other main parameters are given. It also describes the areas on the planet most polluted with aerosol dust particles. Dust deposition on the module significantly reduces the generation of electrical energy, which affects its current-voltage characteristic. The electrical properties of dust have been proposed to be used in the development of special devices for cleaning settled dust or preventing dust.
