The dust is the prime ingredient whose accumulation on the surface of PV impacts negatively over its efficiency at a greater rate. 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 .
As the dust settles on the PV module surface, it reduces the transmittance of solar radiation through the glass, resulting in higher absorption of solar energy by the dusty module. This increased absorption leads to an elevation in the PV surface temperature, impacting the overall performance and efficiency of the PV module.
The data in Table 3 for rice husk indicate that a uniform layer of 5 g dust accumulation on solar PV module can reduce its power up to 20%, and at a dust accumulation of 50 g on PV module, the power is reduced approximately 70%.
Ambient temperature has a higher negative impact on the thin film panels’ (TFP) efficiency compared to crystalline panels (CRP) (Touati, Al-Hitmi, and Bouchech 2012). Al Siyabi et al. suggested that the efficiency of crystalline cells reduces by 0.248% for each one degree Celsius increase (Al Siyabi et al. 2019).

6 FAQs about [Dust accumulation reduces the efficiency of photovoltaic panels]
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% .
How much dust accumulated on solar PV module reduce power?
Perusing the data from Table 4, it is concluded that an accumulation of uniform dust layer of 5 gm on solar PV module can reduce its power up to 13%, and when 50 g of the dust is accumulated on PV module uniformly, the power is found to be reduced approximately 50%.
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.
Does a small layer of dust affect solar PV system efficiency?
Due to accumulation of dust particles on the surface of solar PV systems, and output power is reduced to a large extent. It is concluded that a small layer of dust itself reduces PV system efficiency to a large extent. The minimum power value of 3.88 W is obtained during the accumulation of rice husk on the solar PV module.
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.
Does dust accumulation affect PV voltage?
The analysis revealed a significant impact on PV current due to the reduced incident light intensity reaching the PV cell. However, the effect on PV voltage was relatively minor, as dust accumulation mainly influenced the optical properties of the light-absorbing layer.
