bertin Posted August 14, 2014 Share Posted August 14, 2014 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 Link to comment Share on other sites More sharing options...
Bruno Wittmer Posted August 15, 2014 Share Posted August 15, 2014 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 Link to comment Share on other sites More sharing options...
bertin Posted August 18, 2014 Author Share Posted August 18, 2014 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)! Link to comment Share on other sites More sharing options...
André Mermoud Posted August 18, 2014 Share Posted August 18, 2014 You can have a look on our FAQ How is defined the plane orientation? Link to comment Share on other sites More sharing options...
