Peak sun hours a day on flat ground. Each dot is one place.
The sunniest place in Oman is Adam (Ad Dakhiliyah) with 6.24 peak sun hours a day on flat ground; the least sunny is Khasab with 5.71. A 1 kWp array at its best angle makes from 1,761 kWh a year in Khasab to 1,909 kWh in Adam — 1,840 kWh on average.
The best year-round tilt runs from 19° in Şalālah to 24° in Şaḩam. Off-grid systems are sized for the darkest month and do better steeper, at 24° on average: at 70° that month brings 1.86 kWh per kWp a day in Şalālah and 2.34 kWh in Khasab.
