Post subject:  How is defined the plane orientation ?

In PVsyst the orientation conventions are (contrary to Architect's conventions):

- For Northern hemisphere, the Azimuth = 0° corresponds to the South.
The azimuth is positive towards west (clockwise angles).
Therefore: East = -90°, West = +90°, North = + or -180°

- For Southern hemisphere, the Azimuth = 0° corresponds to the North.
The azimuth is positive towards west (anti-clockwise angles).
Therefore: East = -90°, West = +90°, South = + or -180°


These configurations are explicit on the little graphs when defining the plane orientation.

Note about red dots: The red dots have no "physical" meaning (it is not the same point on both diagrams) !
By convention in PVsyst the red dot is always a dot that you can drag with the mouse.
For example in the Orientation graphs, on the left diagram it commands the tilt, and on the right diagram it commands the orientation.
