Peak sun hours a day on flat ground. Each dot is one place.
The sunniest places in Peru, with 6.60 peak sun hours a day on flat ground, are Ciudad Satelite and one other place; the least sunny is La Peca with 4.16. A 1 kWp array at its best angle makes from 1,236 kWh a year in La Peca to 2,107 kWh in Ciudad Satelite — 1,605 kWh on average.
The best year-round tilt runs from 3° in Tumbes to 19° in Arequipa. Off-grid systems are sized for the darkest month and do better steeper, at 12° on average: at 70° that month brings 0.98 kWh per kWp a day in Tambo Grande and 1.80 kWh in Ayaviri.
