This research aims to explore the effects of dust accumulation on the energy output and operating temperature of polycrystalline silicon PV panels situated in two different climatic regions of Pakistan, i.e., Islamabad and Bahawalpur. In both the regions, one PV module is kept in ambient environment for six weeks to allow dust to deposit over .
While dry dust has a limited impact on the productivity of PV, dust accumulation on these panels followed by light rain or high humidity produces a sticky layer on the surface, especially those with small tilt angles. The same situation is repeated with dusty rain, which forms a layer on the surface of the PV requires expensive cleaning.
Dust accumulation on the PV panels is an area of growing concern for the reliability of solar panels; dust mitigation of solar photovoltaics is a main aspect of maintenance required for enhanced and longer yield performance of PV panels. Wind sweeps dust and dirt onto the solar panel surface, causing the dust to cover the entire panel, which .
A small amount of rain, instead of cleaning the panel surface, increased the dust deposition and quite often contributed to the formation of insoluble chemical compositions (salts) on the surface of the panels as well as permanent partial “cementing” of dust deposited there.

6 FAQs about [Dust accumulates on photovoltaic panels after rain]
What factors affect dust accumulation on PV panels?
A surface which can get effected by the heat can get sticky while promoting adhesive residues, dust, and soiling. Similarly, the tilt angle plays a major role since an inclined surface attracts less gravity and hence less dust accumulation as compared to a flat or horizontal surface. Fig. 7. Factors involved in dust accumulation on PV panels. 2.2.
