This study mainly focuses on understanding the properties of dust particle deposition (Cement, Brick powder, White cement, Fly ash, and Coal) on a solar photovoltaic (PV) panel under.
Testing several dust types on the edge of the PV panel disclosed that dust, like “ash” and “soil”, causes a temperature rise of the panel compared to other dust types. They also experimentally measured losses from 10%–16% in power when dust accumulates on the bottom edging of the solar panel.
Research on the effects of deposits of red soil, sand, ash, and calcium carbonate highlighted that the deposits of finer particles such as ash caused a greater reduction in the performance of the photovoltaic panel, about 25% of the PV voltage reduction, compared to the coarse ones .
The results of the study showed that the accumulation of ash causes the highest decrease in electricity generated from PV as the effort of the PV containing ash decreased by 25% compared to a clean PV.
The effects of snowfall, ash accumulation density and PV module angle on the output power and power attenuation rate of PV modules were investigated. The experimental results show that snowfall had both positive and negative effects on PV modules. The output power of the PV module decreases as the ash density increases.

Figure. 4 % η reduction response of different dust particles on PV panel in th is study. and respectively. Both the power loss and efficiency are calculated based on the difference in values
Does dust accumulation affect the efficiency of mono-crystalline photovoltaic panels?
It was illustrated that the efficiency of mono-crystalline Photovoltaic panels decreases by approximately 10% following 100 days of dust accumulation of the PV module surface (Fathi et al., 2017a).
Does dust soiling reduce power from PV modules?
The accumulation of dust on any given photovoltaic (PV) module surface depends on the type of dust, environment, surroundings, weather, module properties, and its installation design. In this research, equations were developed for the preliminary evaluation and comparison of the reduction in power from PV modules because of dust soiling.
