Plane orientation

[bertin]

Hello,

PVsyst guide states : "In southern hemisphere, the plane azimuth is defined as the angle between north and collector plane.This angle is taken as negative toward east".

However, if I put -135° in the "Orientation" pane (projet in the south hemisphere), I get a north-west orientation (instead of south-east).

Should I believe the PVsyst guide or the drawing?

Thanks in advance,

Sébastien

Which PVsyst Version are you using?

I just tested in PVsyst 6.26 for Auckland, New Zealand, and the azimuth -135° gives, as expected, a drawing facing south-east in the orientation dialog.

Could it be that you mis-interpret the sketch? On the right side, in the view from the top, the red and black dots are on ground level!

Best regards,

Bruno

Thank you Bruno. Indeed, I thought the red dot was on the top of the collector (as it appears on the drawing on the left)!
