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.

Interview: Green Energy Park talks soiling and its effects on PV systems

Dr. Ahmed Alami Merrouni, responsible for R&D in Meteorology and Solar Materials degradation at Morocco-based Green Energy Park (GEP), talks about the challenges and opportunities for PV projects in the region. Soiling, he says, is a specific issue, which can impact both ROIs and O&M. In addition to explaining why GEP uses Kipp & Zonen’s DustIQ solution, he says the company is developing new software, which can offer bespoke module cleaning solutions.
