The solar azimuth angle is the azimuth (horizontal angle with respect to north) of the Sun's position. [ 1 ] [ 2 ] [ 3 ] This horizontal coordinate defines the Sun 's relative direction along the local horizon , whereas the solar zenith angle (or its complementary angle solar elevation ) defines the Sun's apparent altitude .

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. [1] [2] At solar noon, the zenith angle is at a minimum and is equal to latitude minus solar declination angle. This is the basis by which ancient mariners navigated the oceans. [3]
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.
The actual figure varies with the Sun's angle and atmospheric circumstances. Ignoring clouds, the daily average insolation for the Earth is approximately 6 kWh/m 2 = 21.6 MJ/m 2 . The output of, for example, a photovoltaic panel, partly depends on the angle of the sun relative to the panel.
Free Union is a census-designated place (CDP) in Albemarle County, Virginia, United States, [1] ten miles north-northwest of Charlottesville. The population as of the 2020 Census was 187. [ 2 ] It is a small hamlet consisting of a private school (Free Union Country School), a doctor's office, a post office, a homebuilder, and several dozen homes.
A company that bred beagles for medical research agreed Monday to pay a record $35 million as part of a criminal plea admitting it neglected thousands of dogs at its breeding facility in rural ...
Trigonometry tells us that the sine of a 30° angle is 1/2, whereas the sine of a 90° angle is 1. Therefore, the sunbeam hitting the ground at a 30° angle spreads the same amount of light over twice as much area (if we imagine the Sun shining from the south at noon, the north–south width doubles; the east–west width does not ...
