What is the best way to clean photovoltaic panels without water

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 a waterless system clean solar panels?

But waterless cleaning methods are less effective and labor-intensive and tend to scratch the panels, which also reduces their efficiency. Now, MIT researchers have devised a waterless, no-contact system to automatically clean solar panels or the mirrors of solar thermal plants.

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:

Can you use deionized water to clean solar panels?

Solar maintenance companies like US-based Bland Company and Premier Solar Cleaning have found that using deionized water with a rolling or vehicle-mounted brush allows them to clean panels without using soap, which leaves a residue that not only shades panels but attracts dirt.

How do you clean solar panels?

Cleaning solar panels isn't a one-size-fits-all task. Different methods suit different needs, each with its own set of pros and cons. The soft brush and mild, eco-friendly soap method. Note: If you use this method, be sure to use a long-handled roof brush so you can clean your panels from the safety of the ground.
