azimuth angle for single axis tracking?

I have a single axis tracking PV system with east west tracking with zero tilt.(Rotation axis in north south direction)

Now I have panels mounted in landscape mode in north south direction.(attached pdf file of top view)

So the azimuth of the system will be 90° correct?

Hello,

If the system is in the northern hemisphere, and the rotation axis is north-south so that the modules face the east in the morning and the west in the evening, then you should use an azimuth angle of 180 degrees.

Best regards,
Paul.
