Plane azimuth

As a contrary to the usual architect's conventions, in PVsyst we consider:

In northern hemisphere, the plane azimuth is defined as the angle between south and collector plane. This angle is taken as positive toward west, i.e. goes in the antitrigonometric direction. => south azimuth = 0, north azimuth = 180°, west azimuth = 90°, east azimuth = -90°.

In southern hemisphere, the plane azimuth is defined as the angle between north and collector plane. This angle is taken as negative toward east, i.e. goes in the trigonometric direction. => north azimuth = 0, south azimuth = 180°, west azimuth = 90°, east azimuth = -90°.
