Thanks for the clarification Andre...I was looking at the diffuse shading factor independent of the irradiation model which already accounts for the shading "behind" a tilted array as labeled in your shading table.

When I create a PV array with a 30 degree tilt in the scene creator and then generate the shading table, the diffuse factor is zero. Why? I thought the diffuse shading model with an isotropic shading model over the entire skydome? Should'nt there be some loss when considering a tilted array?
