cleaning system

An international research team has developed a cleaning system for solar panels that combines a vibrating device with the use of hydrophilic curved rungs. The technique is claimed to be able to remove the surface contaminants through the internal flow of vibrating water droplets applied with a pipette onto the module surface and transported, under vibration, to the contaminated parts.

Indian startup Solavio Labs has designed a modular, autonomous bot to clean solar panels. The system is purportedly compatible with most structures, mounting areas, and climate conditions.

Researchers in Egypt have tested a new solar module cleaning technique for solar arrays in arid regions. They claim that the combination of nano-coatings with vibration mechanisms on the backs of modules can reduce manual cleaning requirements.

French researchers have developed a machine-learning model to clean low-power PV projects and standalone solar arrays in rural areas isolated from the grid.
