What is Azimuth angle?
Angle between direction to the sun and direction to the south (for the northern hemisphere). For a PV installation, azimuth specifies how far the installation orientation is deviated from the south. If the azimuth angle is 0°, the system faces the south directly. If the system’s alignment deviates to the east, the value is negative. In case of deviation to the west, the value will be positive.
