The formula to calculate the azimuth angle is:
\[ \text{Azimuth Angle} = (\text{Peak Load Hour} - 12) \times 15 + (\left| \text{Longitude} \right| - 116) \]
where:
The azimuth angle is the angle between the north direction and the perpendicular projection of the sun's rays on the horizontal plane. It is used in solar panel positioning to maximize energy capture.
The azimuth angle of a solar panel is the angle between the vertical plane of the panel and the due south direction (a negative angle is set for deviation to the east, while a positive angle is set for deviation to the west).
Let's assume the following values:
Using the formula:
\[ \text{Latitude} \approx 34.09° \approx 34° \]
\[ \text{Longitude} \approx -118.41° \approx 118° \]
\[ \text{Azimuth Angle} = (14 - 12) \times 15 + (118 - 116) = 30 + 2 = 32° \]
The Azimuth Angle is approximately 32°.
