Can a waterless cleaning method remove dust from solar panels?

Dust that accumulates on solar panels is a major problem, but washing the panels uses huge amounts of water. MIT engineers have now developed a waterless cleaning method to remove dust on solar installations in water-limited regions, improving overall efficiency. Image courtesy of the researchers.

Can electrostatic cleaning remove dust from solar panels?

Dust removal for solar panels via electrostatic cleaning – pv magazine International A Jordanian research team has designed a cleaning technique for solar modules that uses static electricity to remove dust from panel surfaces.

How do you clean dust off solar panels?

One of the most common ways to clean dust off solar panels is to spray them with water. But that’s a huge waste of water, especially in desert settings, where there are a lot of solar farms. The MIT scientists note in their new study, which is published in Science Advances:

How to remove dust from PV panels?

Sometimes, special cleaning agents are mixed with high-pressure water to enhance dust removal efficiency , , . Additionally, the presence of water helps cool the PV panels , . However, this method is not suitable for semi-arid and arid regions facing severe water scarcity .

Can static electricity remove dust from solar panels?

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.

Can a lab-scale solar module cleaning system remove dust from solar panels?

In March, scientists from the Massachusetts Institute of Technologyhave developed a lab-scale solar module cleaning system prototypethat uses electrostatic repulsion to cause dust particles to detach and virtually leap off the surface of panels.
