Peak sun hours a day on flat ground. Each dot is one place.
The sunniest place in Botswana is Letlhakane (Central) with 6.18 peak sun hours a day on flat ground; the least sunny is Bobonong with 5.67. A 1 kWp array at its best angle makes from 1,792 kWh a year in Bobonong to 1,951 kWh in Letlhakane — 1,888 kWh on average.
The best year-round tilt runs from 23° in Maun to 27° in Gaborone. Off-grid systems are sized for the darkest month and do better steeper, at 23° on average: at 70° that month brings 1.82 kWh per kWp a day in Maun and 2.18 kWh in Janeng.
