Solar energy
Average daily shortwave solar energy reaching the ground, banded into brightness zones so the number means something at a glance.
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.
Boa Vista do Tupim receives about 4.9 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 3.4 and 6.0 kWh/m².
The brighter stretch of the year lasts 6.7 months, from around Sep 16 to Apr 8. The brightest month is December, averaging about 5.9 kWh/m² (bright).
The dimmest month is June, down near 3.4 kWh/m² — roughly 42% less than the December peak.
