Effect of Soiling on Solar Photovoltaic Performance under Desert Climatic Conditions

The solar irradiation at the gulf Arabia is considered one of highest in world. However, this region classified as a desert with high dust accumulation. Thus, objective study to analyze effect soiling and photovoltaic (PV) tilt angle on performance 2.0 MWp car park PV plant Oman. Experimental measurements were taken model was developed for simulation. power generation by cleaned system measured 1460 kW around noon. After week operation, production (at same irradiance level) reduced 1390 due soiling. It further 1196 904 after three five weeks respectively. results also show that soiling-percentage 7.5% monthly electricity (307 MWh) 5.6% 12.5% 10.8%. Furthermore, increase not recommended duo-pitch canopy where panels 180° azimuth generate lower than 0° azimuth. In addition, part caused shading other angles.
