This review examines the impact of dust on PV performance and evaluates cleaning approaches, including electrostatic removal, super hydrophobic and super hydrophilic coatings, surface acoustic wave (SAW) technology, robotic systems, and manual methods.

Researchers from the University of Jordan have proposed the use of electrostatic cleaning as an effective way to remove dust from solar panels. Electrostatic cleaning involves the spraying of electrostatically charged mist with low-frequency high voltage onto surfaces and objects.

To prevent shading during the cleaning process, it is best to carry out dust removal work in the morning or evening when the light is weaker. Winter snowfall can cover PV modules, blocking sunlight and severely affecting their power generation efficiency.
