Peak sun hours a day on flat ground. Each dot is one place.

The sunniest place in Uganda is Soroti (Eastern Region) with 6.08 peak sun hours a day on flat ground; the least sunny is Kisoro with 4.88. A 1 kWp array at its best angle makes from 1,449 kWh a year in Kisoro to 1,776 kWh in Soroti — 1,594 kWh on average.

The best year-round tilt runs from 0° in Mpondwe to 6° in Moyo. Off-grid systems are sized for the darkest month and do better steeper, at 0° on average: at 70° that month brings 0.97 kWh per kWp a day in Ngora and 1.19 kWh in Mabare.
