Peak sun hours a day on flat ground. Each dot is one place.
The sunniest place in Burundi is Cendajuru (Cankuzo) with 5.25 peak sun hours a day on flat ground; the least sunny are Gatumba and one other place with 4.92. A 1 kWp array at its best angle makes from 1,463 kWh a year in Gatumba to 1,561 kWh in Cendajuru — 1,502 kWh on average.
The best year-round tilt runs from 4° in Kirundo to 7° in Rumonge. Off-grid systems are sized for the darkest month and do better steeper, at 0° on average: at 70° that month brings 1.14 kWh per kWp a day in Rumonge and 1.21 kWh in Cendajuru.
