Anti-Soiling Coating Technologies for PV Panels Under Dust Storm Conditions
Abstract: Background: Deployment of photovoltaics (PV) in arid and semi-arid areas where there is ample sunlight has been increasing quickly because of their high solar irradiation. The rising number of dust storms, as well as depositing particulate matter into the air, has caused a significant decrease in energy production due to reduced transmittance of light through the surface of the PV panel from the dust on the panel’s surface. This has …
