Peak sun hours a day on flat ground. Each dot is one place.
The sunniest place in Mauritius is Goodlands (Rivière du Rempart) with 5.74 peak sun hours a day on flat ground; the least sunny is Curepipe with 5.63. A 1 kWp array at its best angle makes from 1,710 kWh a year in Curepipe to 1,744 kWh in Goodlands — 1,724 kWh on average.
The best year-round tilt is 18° everywhere. Off-grid systems are sized for the darkest month and do better steeper, at 35° on average: at 70° that month brings 1.83 kWh per kWp a day in Goodlands and 1.86 kWh in Mahébourg.
