Cleaning without water

Key Points

The aim is to develop a sustainable cleaning method for solar panels that operates without water or harmful chemicals.
Developed an electrostatic cleaning technique for solar panels.
Tested the method in desert environments with high sand accumulation.
Analyzed the effect on photovoltaic (PV) efficiency and cost savings.
The method successfully removes sand and restores PV efficiency.
Significant reduction in power loss was observed after cleaning.
Cost savings were noted, particularly for manual cleaning processes.

Abstract

This work develops a sustainable electrostatic cleaning method for solar panels in desert regions, enabling removal of sand without water or harsh chemicals. Analyses show this method effectively restores PV efficiency, reduces power loss, and offers cost savings, especially in manual use, making it an eco-friendly alternative for large-scale solarenergy production.
