Soiling and Irradiance Measurements in Bifacial Systems Using In-Situ Module I-V and Rear-Side Reference Cells

We performed an 11-month field test to examine soiling and irradiance measurements in a bifacial PV system. We demonstrate two methods, denoted “module-module” and “module-cell”, of determining soiling ratio - the ratio of actual power to expected power under clean conditions - using soiled module p...
