Development of Effective Device for Protection of Solar Modules from Contamination

Abstract

This paper considers the problem of the contamination of the solar modules´ surface in the industrial megalopolis. It shows the methods of manual and automated cleaning and the characteristics of contaminant´s composition. A new device construction for protecting modules from finely divided dust, based on electron-ion technology principles is proposed. It is established that the catch level of dust particles is determined by the Deutsch formula and depends on the electric field voltage, created by the high potential of the precipitation plates. The calculation of catching dust particles efficiency depending on the air flow speed is done. A pulse source scheme of a high-voltage is developed.
