WebThe zenith angle is the angle between the sun’s rays and vertical at any given point on Earth. Key Takeaways: Zenith angle refers to the angle between the sun and vertical. Zenith angle and solar altitude angle will always add up to 90°. The sine of the zenith angle will always equal the cosine of the solar altitude angle, and vice versa. 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.
