However, dust agglomeration on the surface of photovoltaic panels causes damage and impedes their ability to efficiently turn sunlight into electricity. Because condensation is a driving force in dust aggregation, Hu et
In spite of high solar radiation being an advantage for the performance of solar photovoltaic (PV) panels, the caused high surface temperature of the panel surface reduces their efficiency, as

The elevated temperature and dust accumulation over the photovoltaic (PV) surface are the main causes of power loss in hot and desert climates. Traditionally, PV cleaning and cooling are addressed separately, and
The AWGPV panel, short for Atmospheric Water Generation on PV panel, is specifically designed to facilitate water condensation and is intended for nighttime operation. The process of
PV panels hydrophobic coatings help repel water formed on the surfaces to roll off and carry away the accumulated dust particles. This technology is considered efficient and cost-effective compared to other cleaning methods [ 16 ].
The variable dust accumulation at any point on the PV surface results in a different distribution of sunlight entering the PV array, increasing the possibility of a hot spot that damages the PV panels 8. Higher dust density reduces PV short-circuit current, open-circuit voltage, and output power.
Therefore, a prepared PDMS/SiO2 nanocoating was used to reduce the accumulated dust on the PV panels' surface. However, the effectiveness of these coatings is greatly influenced by geographical and climatic factors. Three identical PV modules were installed to run comparable experimental tests simultaneously.
Radiation loss due to dust accumulation reduces PV output power. The variable dust accumulation at any point on the PV surface results in a different distribution of sunlight entering the PV array, increasing the possibility of a hot spot that damages the PV panels 8.
While on the other hand, coating of a PV panel decreases the required cleaning frequency of PV panels and increases the efficiency of the system. PV module that was continuously cleaned for over a month experienced a 9.22% power gain compared to the unclean PV module.
However, dust accumulation on solar PV surfaces, referred to as soiling, has become a major issue for solar energy generation, due to the induced power losses [ 2 ]. In 2018, solar power production was reduced by 3–4%, which in turn caused 3–5 billion euros of revenue losses.
