Peak sun hours a day on flat ground. Each dot is one place.
The sunniest place in the Gambia is Farafenni (North Bank) with 5.86 peak sun hours a day on flat ground; the least sunny is Gunjur with 5.73. A 1 kWp array at its best angle makes from 1,705 kWh a year in Gunjur to 1,726 kWh in Farafenni — 1,718 kWh on average.
The best year-round tilt is 14° everywhere. Off-grid systems are sized for the darkest month and do better steeper, at 2° on average: at 70° that month brings 1.55 kWh per kWp a day in Gunjur and 1.59 kWh in Farafenni.
