Step-by-Step Calculation. To calculate solar elevation, we''ll use a specific formula involving the latitude of your location and the declination angle of the sun. The formula is: [ alpha = 90° - phi + delta ] Where: ( alpha ) is the solar elevation angle.
The solar elevation formula is as follows: Here, ɑ is the solar elevation angle, δ is the declination angle, ɸ is the latitude of your location, and h is the solar hour angle. Therefore, we require three variables (latitude, declination, hour angle) to calculate the elevation of the sun. Let’s one-by-one understand each of the three.
The solar elevation angle (or solar latitude angle) is a measure of the angular position of the sun in the sky.
From the previous figure, a formula for the elevation angle at solar noon can be determined according to the formula: When the equation above gives a number greater than 90° then subtract the result from 180°. It means the sun at solar noon is coming from the south as is typical the northern hemisphere.
The solar elevation is the angular distance between the imaginary horizontal plane on which you are standing and the sun in the sky. It is also known as the solar latitude angle and measured in degrees. In simple words, it tells at what height the sun is in the sky. In the morning and evening, the sun is low in the sky, near the horizon.
If the angle is negative, it means it is dark; the sun has either not yet risen or has transcended beyond the horizon. The solar elevation formula is as follows: Here, ɑ is the solar elevation angle, δ is the declination angle, ɸ is the latitude of your location, and h is the solar hour angle.
The solar incidence angle on a plane of tilt α and slope β (ν (β, α)) is the angle between the normal to the plane on which the Sun is shining and the line from the surface passing through the center of the solar disk. The cosine of ν (β, α) is used to estimate the incident beam irradiance on a surface from the irradiance normal to the beam.
