1 Methodology. The azimuth is the PV array’s east–west orientation in degrees. In most solar PV energy-calculator tools, an azimuth value of zero is facing the equator in both northern and southern hemispheres; +90° degrees is facing due west and –90° degrees is facing due east.
What is the best azimuth angle for solar panels?
Since solar panels are more productive when the sun’s rays are perpendicular to their surfaces, the certainly best orientation is the one directly true SOUTH (azimuth angle = 180 °).
What is my azimuth angle?
The azimuth angle is the compass direction from which the sunlight is coming. At solar noon, the sun is always directly south in the northern hemisphere and directly north in the southern hemisphere. … The azimuth angle is like a compass direction with North = 0° and South = 180°.
How do you choose an azimuth angle?
Optimal Azimuth Angle For Solar Panels. For best results, your solar panels should face toward the equator. If you live in the Northern Hemisphere, face them south. If you live in the Southern Hemisphere, face them north.
What is azimuth used for?
Azimuth and Elevation are measures used to identify the position of a satellite flying overhead. Azimuth tells you what direction to face and Elevation tells you how high up in the sky to look. Both are measured in degrees. Azimuth varies from 0° to 360°.
How do you find the solar azimuth?
In most of the solar PV energy calculator tools, an azimuth value of zero is facing the equator in both northern and southern hemispheres. Positive 90 degrees is facing due west, negative 90 degrees is facing due east.

Calculating Your Optimal Azimuth Angle.
| Azimuth Angle (degrees) | Phoenix, AZ (33 North) | |
|---|---|---|
| -90 (East) | 5,601 | -13% |
| 180 (North) | 4,298 | -34% |
Which direction is best for solar panels?
What is the best direction for my solar panels? The traditional advice is to position solar panels to be south-facing. This is because, for those of us living in the Northern Hemisphere, the sun is always along the southern part of the sky as we complete our yearly orbit around it.
What are examples of azimuth?
The azimuth is the angle between North, measured clockwise around the observer’s horizon, and a celestial body (sun, moon). It determines the direction of the celestial body. For example, a celestial body due North has an azimuth of 0º, one due East 90º, one due South 180º and one due West 270º.
Is bearing and azimuth the same?
A bearing is an angle less than 90° within a quadrant defined by the cardinal directions. An azimuth is an angle between 0° and 360° measured clockwise from North. “South 45° East” and “135°” are the same direction expressed as a bearing and as an azimuth.
What is azimuth and altitude?
Altitude in this sense is expressed as angular elevation (up to 90°) above the horizon. Azimuth is the number of degrees clockwise from due north (usually) to the object’s vertical circle (i.e., a great circle through the object and the zenith).
Is azimuth the same as longitude?
For the equivalent of longitude, the Horizontal System uses azimuth. Azimuth is the East to West Coordinate, with 0 degrees of azimuth at North, 180 degree at South, etc. The latitude equivalent is altitude. The horizon and the observer’s zenith define 0 degrees and 90 degrees of altitude, respectively.
What is azimuth angle in surveying?
What is Azimuth in Surveying? Azimuths are defined as horizontal angles that are measured from the reference meridian in the clockwise direction. Azimuths are also called a whole circle bearing system(W.C.B). Azimuths are used in compass surveying, plane surveying, where it is generally measured from the north.
What is an azimuth in surveying?
azimuth—The determination of the horizontal angle between North (grid, geodetic, magnetic, astronomic) and an established mark. See also angle, azimuth; angle, zenith. A horizontal angle determined directly from the observation of the sun, moon, or stars. …
What is another word for azimuth?
In this page you can discover 15 synonyms, antonyms, idiomatic expressions, and related words for azimuth, like: declination, 15deg, 5deg, 60deg, altazimuth coordinate system, az, 10deg, 180deg, right-ascension, 30deg and azimuthal.
What is the difference between zenith and azimuth?
is that azimuth is an arc of the horizon intercepted between the meridian of the place and a vertical circle passing through the center of any object; as, the azimuth of a star; the azimuth or bearing of a line surveying while zenith is (astronomy) the point in the sky vertically above a given position or observer; the …
What is true azimuth?
In navigation, the true azimuth of a heavenly body is the arc of the horizon between the point where a vertical plane containing the observer and the heavenly body intersects the horizon and the direction of true north.
