 Figure 5 - PV Table structure groups. PV tables have diagonals that start from the smallest pole of the group and end at the largest pole of the group. The length and angle of the diagonals are calculated automatically. 
 
-You can set the `PanelOffset`, this the distance between the structure's group and the panel center, this parameter is always calculated along the normal of the panel.

 **Warning**: If the tilt angle is too high for the given base height, the structure may extend below ground level. Ensure that `Height` or `PoleSpacingX` is increased, or `TiltY` is decreased, to avoid a `ValueError`: "Invalid PVTable configuration: The tilt angle is too high for the given base height. This results in the structure extending below ground level. Please increase 'Height' or 'PoleSpacingX' or decrease 'TiltY'."
