The solar zenith angle is the zenith angle of the sun, i.e., the angle between the sun’s rays and the vertical direction. It is the complement to the solar altitude or solar elevation, which is the altitude angle or elevation angle between the sun’s rays and a horizontal plane.
May 21, 2024 · The zenith angle is the angle between a point of interest and the zenith — the point directly overhead. In a three-dimensional coordinate system, the zenith is the axis perpendicular to the horizontal plane. Zenith angle is measured from a local zenith, meaning that it changes based on the location of the person or device making the measurement.
In a scientific context, the zenith is the direction of reference for measuring the zenith angle (or zenith angular distance ), the angle between a direction of interest (e.g. a star) and the local zenith - that is, the complement of the altitude angle (or elevation angle ).

The zenith angle is the angle between the sun and the vertical. The zenith angle is similar to the elevation angle but it is measured from the vertical rather than from the horizontal, thus making the zenith angle = 90° - elevation.
Surface azimuth angle (γ) – angle between surface normal and south direction in horizontal plane, (+180o to -180o, +ve in the east of south) Hour angle (ω) – angular measure of time w.r.t. noon (LAT), 15o per hour, (+180o to -180o, +ve in the morning)
The solar zenith angle is the angle that is formed between the sun and vertical (or straight up) at any given point on the earth. For instance, if the sun was straight in front of an observer at the horizon, the angle between horizontal and vertical would be 90°.
6 days ago · The zenith angle is an angle measured from the z-axis in spherical coordinates, denoted phi in this work. It is also known as the polar angle and colatitude.
PVEducation Zenith Angle is the angle between the sun and the vertical at any time of the day. It affects the amount of solar radiation received by a surface and the optimal tilt of a solar panel. This webpage explains the concept of zenith angle, how to measure it, and how it changes with time and location.
The Zenith Angle ( θz) is the geometric complement of the solar altitude angle. We direct your attention to the use of θ here, as the general concept of the angular deviation of the Sun's ray from the normal projection of a surface is called the angle of incidence, θ.
