Dry and sunny locations are highly favorable for cost effective energy generation from PV modules. However, with few exceptions, these locations expose the module glass surface to dry dust and soil, which can accumulate on the surface and reduce light transmission and power output. A number of researchers have attempted to quantify the effects of this soiling. One study found that efficiency for a PV system declined by approximately 0.16% per day between significant rainfalls, resulting in...
