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.

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:

Do solar PV panels need to be cleaned?

That said, most solar pv panels in the UK will not need any heavy-duty cleaning because regular rain will wash most dirt and grime off the surface, dispelling one of the myths about solar being its difficulty to clean.

How to clean solar panels effectively?

Now that you have everything you need, let's dive into the step-by-step guide for cleaning solar panels effectively. Timing is crucial when cleaning solar panels to ensure optimal results and safety. It's best to clean them early in the morning or late afternoon when the sun's rays are less intense, and the panels are cooler to the touch.

Can you use vinegar to clean solar panels?

Vinegar is a great cleaning agent for solar panels because it contains acetic acid, which is very capable of breaking down tough stains, dirt and grease. It is also readily available and any vinegar will do although the best type to use is white cleaning vinegar.

Can a cleaning brush be used on solar panels?

It can be used on both solar thermal panels as well as solar PV and is a non-caustic formula. This cleaning brush is specially designed to clean solar panels with a 7.5metre telescopic rod and rotating circular brushes with a direct water feed.
