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.

Floresta do Araguaia receives about 5.2 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.5 and 6.1 kWh/m².

The brighter stretch of the year lasts 4.9 months, from around Jul 6 to Nov 30. The brightest month is September, averaging about 6.1 kWh/m² (intense).

The dimmest month is March, down near 4.6 kWh/m² — roughly 24% less than the September peak.
