Determining soiling losses on PV modules in a desert climate

By David Daßler; Stephanie Malik; and Akshayaa Pandiyan of Fraunhofer CSP

Understanding the impact of soiling on PV modules and thus the most appropriate cleaning regime, is critical to preventing losses in module power and plant yield. The Fraunhofer CSP team describes a statistical method they have developed for accurately characterising the losses from soiling in desert conditions
