Peak sun hours a day on flat ground. Each dot is one place.
The sunniest place in Niger is Arlit (Agadez) with 6.52 peak sun hours a day on flat ground; the least sunny is Gaya with 5.74. A 1 kWp array at its best angle makes from 1,683 kWh a year in Gaya to 1,947 kWh in Arlit — 1,815 kWh on average.
The best year-round tilt runs from 13° in Gaya to 19° in Arlit. Off-grid systems are sized for the darkest month and do better steeper, at 5° on average: at 70° that month brings 1.46 kWh per kWp a day in Gaya and 2.03 kWh in Arlit.
