WebSolar zenith angle is the sun’s inclination when you look at it from the earth’s surface or horizon. In the course of the day, this angle keeps changing, and it reaches the maximum elevation at around midday. During sunrise and sunset, the elevation of the sun is at 0 o.At noon, the sun is perpendicular to the ground level, an elevation known as solar altitude. Web15.5 Zenith Angle. 15.5. Zenith Angle. The solar radiation layers are for flat ground but often we need to compute radiation at different angles relative to the sun’s rays, for which we need to know the zenith angle. This is the angle the sun is in the sky relative to a point directly overhead (so a zenith angle of 0 degrees is when the sun ...
