【 摘 要 】

The atmosphere is contaminated with certain minute particles of size 500μm. The deposition of these dust particles over the panel surfaces is referred as Soiling of Photovoltaic (PV) panels. The particulate matters originating from agricultural activity as well as construction works. air pollution. pollen. bird droppings and growth of lichens are the main sources of soiling on the PV panels. It is influenced by location-based meteorological conditions like rainfall. wind speed. and humidity. tilt angle. the sources of soiling. and the texture of cover glasses. The soiling is one among the major losses in the PV performance. Owing to this reason. the PV panels should be cleaned at regular intervals. There are manual and self-cleaning methods. The cleaning by manpower is most common. The self-cleaning comprises of active as well as passive cleaning techniques. This paper reviews about different methodologies used to study the soiling of PV modules and the different factors affecting soiling.
