Dear Ananthu,

The reason for this error message is that you have defined a subarray of 220kWp (982m2) for Orientation 4 in system dialog, whereas the size of your tables in the 3D scene for this orientation is 142m2. You have to increase the size of the tables in the 3D scene for Orientation 4 to 982m2, or reduce the size of your subarray for Orientation 4 in system window to 142m2 in order to have a matching.

You have a similar problem with Orientation 7 (see message in red in your screenshot). The size of the subarray defined in system window for this orientation is not matching the size of the corresponding tables in the 3D scene.

Regards.
