 You can set the `PanelOffset`, this is the distance between the structure's group and the panel center, this parameter is always applied 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'."
