What Is Solar Azimuth Angle?

The solar azimuth angle is the azimuth angle of the Sun's position. This horizontal coordinate defines the Sun's relative direction along the local horizon, whereas the solar zenith angle defines the Sun's apparent altitude.

What is meant by azimuth angle?

The azimuth angle is the compass direction from which the sunlight is coming. ... The azimuth angle is like a compass direction with North = 0° and South = 180°. Other authors use a variety of slightly different definitions (i.e., angles of ± 180° and South = 0°).

How do you find the solar azimuth angle?

The solar azimuth angle is the angular distance between the zero azimuth (either due South or due North, depending on what you select on the input screen) and the projection of the line of sight to the sun on the ground. The azimuth angle is measured clockwise from the zero azimuth.
