Astronomical solar calculator and solar radiation forecast database
Astronomical solar calculator and solar radiation forecast database. Returns highly accurate daily solar cycles: sunrise/sunset times, astronomical/civil/nautical twilights, precise solar noon, day length, maximum UV index, and shortwave solar radiation levels (MJ/m²) for any location globally. Crucial for solar panel yield forecasting, photography timing, agriculture, and outdoor wellness tracking.
