Yield read at the centre of Wadi ad-Dawasir, rounded to 0.1°. Mounting assumed: plants of 50 MW and more on single-axis trackers, smaller ones fixed.
Annual kWh per kWp from PVGIS for crystalline silicon with 14% system loss, multiplied by the capacity as the source states it and taken as peak. A plant rated in MWac carries more DC capacity, so its estimate runs low.
