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

The sunniest place in Malaysia is Kuala Penyu (Sabah) with 5.27 peak sun hours a day on flat ground; the least sunny are Pekan Nenas and 3 other places with 4.60. A 1 kWp array at its best angle makes from 1,324 kWh a year in Pekan Nenas to 1,526 kWh in Kuala Penyu — 1,411 kWh on average.

The best year-round tilt runs from 0° in Kuching to 7° in Kangar. Off-grid systems are sized for the darkest month and do better steeper, at 11° on average: at 70° that month brings 1.05 kWh per kWp a day in Pengerang and 1.25 kWh in Kampung Jeli.
