# Optimize Solar Energy Planning

Solar energy production depends directly on hours of sunlight. Knowing exactly when the sun rises and sets, combined with twilight data, helps estimate the productive window for solar panels. This varies dramatically by location and season.

Use sunrise and sunset data to calculate daily sun hours, track seasonal variation, and compare solar potential across different locations. The data helps with site selection, production forecasting, and understanding when peak generation occurs.
