Dust removal for solar panels via electrostatic cleaning

A Jordanian research team has designed a cleaning technique for solar modules that uses static electricity to remove dust from panel surfaces. The system features an electrostatic ionizer that reduces attraction between dust particles and their accumulation on modules, improving their energy yield.

Color-sensing tech to remove dirt from solar panels

South African researchers have developed a new cleaning system for solar panels that uses a color-sensing light-to-frequency converter to detect dirt. It can reportedly remove around 95% of the dust from a PV panel in less than a minute, at a lower cost than other systems.

‘Footstep tech’ for solar module cleaning

Scientists in South Korea have used a triboelectric generator and an electrodynamic dust shield to develop a panel-cleaning system that can be activated by footsteps. They said the system can remove more than 70% of accumulated dust with the pressure of just 12 footsteps.

Handheld tool to clean rooftop solar panels

Mumbai-based Cleo Tech has developed a battery-powered, handheld tool for scratch-free, dry cleaning of solar panels. The tool’s cleaning brush clings end-to-end on the aluminum frames of the panels, avoiding direct contact of the moving parts with the cells, other than the soft nylon bristles.

MIT scientists develop PV cleaning system based on electrostatic repulsion

Scientists from the Massachusetts Institute of Technology have developed a system that can be operated at a voltage of around 12V, with a 95% recovery rate for lost power after cleaning. The waterless system can be operated automatically via an electric motor.
