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:

Can electrical dynamics remove dust from PV?

The results of the study showed that by increasing the electrical voltage, the amount of dust removed increased. Ref. (M., 2011) studied the effect of the use of the electrical dynamics system to remove dust from PV was investigated with the study of the effect of the mass of dust accumulated on the surface.

Can static electricity keep dust off solar panels?

According to the researchers, static electricity can keep dust off solar panels, and is a much more sustainable solution. And that’s important, because as the researchers note, for example, “Dust accumulation of 5 mg/cm 2 corresponds to almost 50% loss in power output.” Effect of dust accumulation on solar panel power output.

Does dust fouling affect solar collector transmittance?

“Microtrac S3500 Particle Size Analyzer supported by Microtrac FLEX Software was used to characterize the dust particle size distribution. Impact of dust fouling of solar collector transmittance was investigated. PV current, voltage, power, I–V, and transmittance. The monthly decrease in PV efficiency is 7.0%.

Does dust affect the electrical productivity of PV panels?

Conclusions The electrical productivity of PV is seriously affected by the accumulation of dust on their surface.
