Abstract: This paper summarized the impact of photovoltaic (PV) power output by dust accumulation, dust cumulated on PV modules caused a significant decrease of power output, and analyzed the effects of dust capacity, the amount of rainfall, rainfall intensity and rain frequency, wind velocity and wind direction, humidity, vegetation, air pollution, the material of PV module surface and the inclination, azimuth angle of PV modules on dust accumulation. Finally, some suggestions were presented:(1) to study how various factors affect the dust accumulation on photovoltaic module from the microscopic point of view; (2) to study the relationship between environmental air quality, climate characteristics and dust accumulation on PV modules; (3) to establish long-term and remote monitoring system of power output and dust accumulation; (4) to assess the impact of dust accumulation on PV power output, and design dust cleaning system.

Key words: dust accumulation, photovoltaic module, power output, mechanism, impact
