Initial results of a five site study comparing spatial variability of soiling and ambient particulate concentrations

摘要

Initial results from a study examining spatial variations of soiling are presented. Soiling from five sites is examined. Three sites in the area surrounding Denver, Colorado and two additional sites, one in Albuquerque New Mexico, and one in Cocoa Florida at US Department of Energy Regional Test Centers. These locations represent a diverse array of climates in which solar energy may be utilized. These locations represent a diverse array of climates in which solar energy may be utilized. Results highlight similarities and differences between soiling at locations across the United States. In addition to soiling data, ambient particulate data is also collected at the five sites, and results from these measurements, and how they relate to soiling, are presented.
