Peak sun hours a day on flat ground. Each dot is one place.
The sunniest place in Eritrea is Barentu (Gash-Barka) with 6.37 peak sun hours a day on flat ground; the least sunny is Massawa with 5.66. A 1 kWp array at its best angle makes from 1,664 kWh a year in Massawa to 1,902 kWh in Barentu — 1,815 kWh on average.
The best year-round tilt runs from 14° in Assab to 17° in Keren. Off-grid systems are sized for the darkest month and do better steeper, at 6° on average: at 70° that month brings 1.51 kWh per kWp a day in Himora and 1.74 kWh in Keren.
