shading area is far larger than the pv modules area

[mnmasoud]

When designing a large system of 20MW i got the following warning in the near shadings "shading area is far larger than the pv modules area". Can anyone explain to me why i am getting this error? and how to overcome it?

This error means, that there is a mismatch between the total module area as specified in the 'System' dialog, and the total active area as defined in the 'Near Shadings' scene.

You have defined more sensitive area in the 3D scene, than the sum of all modules areas.
