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.
Ixtlán del Río receives about 5.9 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 4.6 and 7.7 kWh/m².
The brighter stretch of the year lasts 4.1 months, from around Feb 17 to Jun 22. The brightest month is April, averaging about 7.5 kWh/m² (intense).
The dimmest month is December, down near 4.6 kWh/m² — roughly 38% less than the April peak.
