Solar energy is how much sunlight actually reaches the ground each day, measured in kilowatt-hours per square metre (kWh/m²) — the combined effect of how long the sun is up, how high it climbs, and how much cloud gets in the way. It's the raw fuel a solar panel has to work with: for scale, 1 kWh/m² a day is dim and wintry, while 7+ is desert-bright.

Faaa receives about 5.5 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.1 and 6.6 kWh/m².
