Soiling loss factor

WebSoiling on photovoltaic (PV) modules is considered a major operations and maintenance cost factor for PV power plant owners. Soiling loss can be heavily influenced by various factors, such as tilt angle, site conditions or environment (urban, rural, agricultural), installation type (fixed vs. 1-axis) and season (dry, windy, humid or rainy).
