How much dust is enough?
A U.K. study has identified 13 soiling agents with differing effects on light transmittance. Researchers found some dust particles were able to degrade photovoltaic performance by as much as 98%.
Another one fights the dust
Scientists from Israel have used nanowires to detach particles from the surfaces of solar panels. The proposed microscopic self-cleaning technology is said to raise the efficiency of particle removal with hydrophobicity.
