Can solar cells self-clean?

Now, no research about the self-cleaning for solar cell array has been motioned in China, and more researching works focus on Lunar or Martian exploration missions on abroad. The cleaning method is summarized as natural means, mechanical means, self-cleaning nano-film, and electrostatic means.

How to clean a solar cell?

The brushing methods clean the solar cell with something like the broom or brush that were driven by the machine was designed just like windscreen-wiper. However, firstly, because of the small size and the strong adhesivity of the dusts, the cleaning method is inefficient.

What is self-cleaning technology for solar cell array?

Journal of Electrostatics, 68 ( 2010), pp. 289 - 298 The self-cleaning technology for solar cell array can promote efficiency of electricity produced and protect the solar cell. The methods of dust-remov…

What are the benefits of self-cleaning solar panels?

Numerous benefits, including anti-graffiti and anti-corrosion, come with the super-hydrophobic thin layer on the surface for self-cleaning PV modules . The electrostatic cleaning system is an additional method that removes sand from solar panels by single-phase high voltage.

What are the self-cleaning methods of PV panel?

Several self-cleaning methods of PV panel have been proposed by researchers and shows positive impact for the future applications. We can classify these self-cleaning methods into two types which are active and passive methods. Active methods such as Electrostatic method and mechanical method which require power for self-cleaning mechanism.

How does a self-cleaning solar module work?

The purpose of this work is to develop an active self-cleaning system that removes contaminants from a solar module surface by means of an automatic, water-saving, and labor-free process. The output efficiency of a solar module can be degraded over time by dust accumulation on top of the cover glass, which is often referred to as “soiling”.
