Error in 3D scene construction

[astha.saxena542]

I have made a 3D scene for single axis tracking PV array. It gives an error "You have deifned a tracking plane in the shadings scene. All tracking parameters should match the orientation definition. The axis orientations don't match". However, I have selected Tracking array: horizontal axis E-0 for PV planes. What could be the possible reason for this error?

As explained in the warning message, you have to specify corresponding orientation parameters in the "Orientation" part and the 3D part.

NB: By the way you should not define a "Horizontal E-W axis", but a "Tilted or Horizontal N/S axis.
