Scientists from the University of Science and Technology of China have conducted a review of research on the dust-scaling process on PV panels and various water-based cleaning methods.

They were able to establish a relationship between different types of dust scales and water-cleaning parameters. Overall, the team has looked through 250 articles published throughout the world up to 2024.

“Pressurized water cleaning improves power generation efficiency by an average of 10.4%,” the academics said. “Weekly water cleaning of PV panels can effectively eliminate dust contamination. The minimum water consumption for aqueous cleaning is 0.31 L/m2, the maximum is 4.95 L/m2, and the average water consumption is 2.1 L/m2.”…
