Self-dusting Solar Panels from NASA Technology

Dust: it’s enemy number one for solar photovoltaic panels (PV) in the sunny, warm areas with the most potential for solar power. That’sbecause it takes less than a tablespoon of dust per square meter toreduce the electrical output of a typical PV panel by 40 percent. “In Arizona,” says Professor Malay Mazumder of Boston University,“dust [...]
