Solar angle

Solar Angle Solar Zenith Angle (SZA): angel between the sun and the point directly above your heat at solar noon –Zenith - 90° from the horizon –Solar noon – sun at the highest point in the day Solar Angle (SA): angle between the sun and YOUR horizon (you are the vertex of the angle)

Declination – the latitude where the noon sun is at zenith (directly overhead, 90°). –The declination varies from 23.5°N and 23.5°S every year – total of 47 ° Latitude – the latitude of the observer (who is checking out the solar angle) –For our calculations, the school is at 41°N latitude

Solar Zenith Angle is found… SZA = Latitude – Declination (if this angle is negative, the sun is in the northern sky; positive-sun is in the southern sky) Solar Angle is found… SA =90 ° - |SZA| manual/how_to/calculating_nsa.html
