Abstract
Abstract The efficiency of solar photovoltaic system is affected by many factors, among which the influence of dust deposition on photovoltaic panels is a prominent problem. In the desert which has sufficient radiation, the problem of dust deposition is quite serious. In some developed cities, photovoltaic devices are affected by dust or aerosol deposition. This short paper, thus, briefly summarizes studies of dust deposition on PV panels of urban and desert areas in recent years, and analyses the influence of dust deposition on the panel, particle characteristics and dust deposition process based on these studies. In general, there are three fields that suggests more research: (1) study on characteristics of sand or dust combined with local environmental characteristics; (2) modeling and simulation of particle dynamics around photovoltaic array; (3) comprehensive laboratory designed experiments to understand the specific influencing factors.
