Peak sun hours a day on flat ground. Each dot is one place.
The sunniest place in Sudan is Mellit (Northern Darfur) with 6.72 peak sun hours a day on flat ground; the least sunny is Port Sudan with 5.78. A 1 kWp array at its best angle makes from 1,708 kWh a year in Tokār to 2,013 kWh in Mellit — 1,880 kWh on average.
The best year-round tilt runs from 12° in Abyei to 19° in Atbara. Off-grid systems are sized for the darkest month and do better steeper, at 4° on average: at 70° that month brings 1.24 kWh per kWp a day in Abyei and 1.98 kWh in Port Sudan.
