Quantification of pv power and economic losses due to soiling in Qatar حسب Zeedan A.

"…For example, for the Al-Kharasaah project power plant, similar soiling loss would result in about a 10% power decrease after six months for typical ranges of dust density in Qatar’s environment; this, in turn, would result in an 11,000 QAR/h financial loss. …"
