Sun Altitude (Annual Variation at the Same Time)
The solar altitude (elevation angle) and direction for one year are calculated on a weekly basis and displayed in a graph.
Azimuth is measured in degrees: North: 0, East: 90, South: 180, West: 270.
The calculation results include an error of a few seconds, which increases at higher latitudes.
