Axis Azimuth for tracking tilted or horiz N-S axis

[smishra24]

Hello,

I am quite new to PVsyst. I am trying to make a system using single-axis tracker with hori N-S axis for a location of latitude 40 degrees. I know that I need to keep axis tilt zero but I am still trying to understand what would the axis azimuth in this case. Considering this case for the Northern hemisphere. I am assuming the face of the panels towards east-west so, in my opinion, axis azimuth should be 90 degrees ( assuming true north = 0 degrees) or whether the collector plane should face south only? Someone, please confirm.

Hello,

The axis azimuth is to be used in cases where the orientation of the axis is deviated from the North/South axis. Meaning that the pv modules axis is not aligned with the North/South axis. Typically such deviation is to be avoided when planting a new system but if the land conditions and/or obstacles do not permit so then you deviate the axis. It is always assumed that South is 0°. Hope i helped. If you need anything more let me know.
