As dust accumulates on the solar PV panel surface, it forms a thin layer that has a negatively effect on the overall energy obtained from the solar PV module (Jaradat et al., 2015; Jiang et al., 2011; Klugmann-Radziemska, 2015).
The reduction in solar efficiency due to dust on PV panel is approximately 40%. In this context, various PV system cleaning methods are adopted currently (Kumar and Chaurasia 2014). The analysis under this category of the environmental effects is the most frequent and problematic one as compared to others.
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.
Abstract—Accumulation of dust from the outdoor environment on the panels of solar photovoltaic (PV) system is natural. There were studies that showed that the accumulated dust can reduce the performance of solar panels, but the results were not clearly quantified.
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%.
Soiling or growing dust on photovoltaic (PV) devices has been at the forefront of serious issues related to the feasibility of solar electricity generation technologies (Alami et al., 2022).

In 2016, 93% of the global PV cell manufacturing capacity utilized crystalline silicon (cSi) technology, representing a commanding lead over rival forms of PV technology, such as cadmium telluride (CdTe), amorphous silicon (aSi), and copper indium gallium selenide (CIGS). .
