I got the following error of duplicated shading surfaces while modeling one detached surface with a hole as a PV surface. I’m not sure if it is caused by the trimmed surface in this case for which EnergyPlus may not be able to process.

It seems this shading surface is duplicated for 7 times, and there are only 3 vertices described for each surface in the IDF file where there should be 8:
The GH file of the simple model is attached here, and appreciate your kind advice.
Thanks.
