The accumulation of dust and aggregation on the surfaces of the PV panels cause a haze of solar irradiation and acts as a shadow; leading to increase the temperature of the PV. The temperature, in turn, reduces the efficiency and performance of PV ( Kazem et al., 2017 ).
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 .
The work in Kazem et al. (2020) discusses the impact of dust accumulation on PV panels followed by analyzing different cleaning methods for PV panels. The cleaning methods discussed include the following: (1) forced air flow of air conditioning system, (2) natural cleaning using rain and wind, (3) water cleaning, (4) manual cleaning, (5 .
Such a testing protocol would assist in the development of the Photovoltaic Soiling Index (PVSI), which is a suggested “dust coefficient” for PV devices used to correlate between the accumulation of dust on the surface of PV panels and their electrical performance in specific locations and within specific time periods.

6 FAQs about [What are the hazards of mud accumulation on photovoltaic panels]
Does dust pollution affect the performance of PV panels?
Characteristics of dust particles and depositions have a significant impact on the performance of PV panels. In this regard, Kazem et al. have provided a comprehensive review of the dust characteristics of six dust pollutants and cleaning methodologies impact on the technical and economic aspects of cleaning (Kalogirou 2013 ).
Does dust accumulation affect PV module efficiency?
The effect of dust accumulation on PV modules has been studied very briefly by them. Efficiency of solar panels is also reduced by dust deposition. Salari et al. reported similar results and according to them, as dust density increases from 0 g/m 2 to 8 g/m 2, efficiency of PV module decreases by 26.36% .
Why is dust accumulating on PV systems a problem?
Dust accumulation on PV systems presents a notable challenge for the solar industry. Dust can reduce the PV efficiency, leading to decreased electricity generation and an overall decrease in performance. Fortunately, there are a number of materials that can be used to prevent dust from accumulating on PV modules.
What is the average dust accumulation on PV modules?
Moreover, the study revealed that the monthly average dust accumulation on the modules was 0.2 g/m 2, and the average performance loss per 1 g/m 2 of dust accumulation was estimated to be 0.4%. These findings could be valuable for guiding future research and facilitating the development of effective dust cleaning methods for PV modules.
Does dust affect PV panel power output in desert areas?
There is a high dust accumulation on PV panel surfaces in desert areas , . Abbas et al. reported that a dust storm can reduce PV module power output by 20%, and long-term exposure can reduce it by 50%. Analyzing the impact of dust in this climate is challenging compared to others .
Does long-term dust accumulation affect the performance of photovoltaic modules?
This paper reviewed the impact of long-term dust accumulation on the performance of photovoltaic modules. It was found that dust accumulation can significantly reduce the efficiency and lifetime of photovoltaic modules, leading to decreased electricity generation and an overall decrease in performance.
