Overview
The position of the Sun in the sky is defined by two angles: Elevation (how high the Sun is above the horizon) and Azimuth (the compass direction from which the Sun is shining).
💡
Pro Tips
Elevation: 0° is the horizon, 90° is directly overhead (zenith).
Azimuth: 0° is North, 90° is East, 180° is South, 270° is West.
Negative elevation means the Sun is below the horizon (night).

Fun Facts
"At the equinoxes, the Sun rises exactly in the East and sets exactly in the West for everyone on Earth."
"Solar panels are most efficient when they are perpendicular to the Sun's rays, which is why tracking systems follow the Sun's angle."
"The 'Solar Noon' is the time when the Sun is at its highest elevation for the day."
