This paper investigates the dust effect on the photovoltaic module (multi-crystalline) performance. The degradation of PV performance due to the deposition of different pollutant types and accumulation has been investigated. Experiments concerning the effects of air pollutants including red soil, ash, sand, calcium carbonate, and silica on the power generated are conducted and analyzed. The results show that the reduction in PV voltage and power is strongly depends on pollutant type and deposition level. The results show that the ash pollutant is the most effecting dust particle on the PV module voltage as compared to the other used dust pollutants. The highest reduction in PV voltage (25%) is recorded when the ash pollutant is used. This paper presents technical information about PV systems performance under Omani desert climate.
