Similar problem for me. I am trying to model carport canopies with bifacial modules. 3 degree tilt. Some projects have only one azimuth, others have multiple azimuths.
However, none of these arrays would fit the description of a "shed" in PVsyst. And defining them in the 3D scene doesn't seem to make a difference--PVsyst says the systems are not suited for the model computation.
Can anyone confirm that modeling bifacial systems, can ONLY happen with sheds? And if yes, any appropriate work-arounds to get by this limitation (e.g. split each array into two subarrays of two sheds each, and make the pitch very large between them?
I have the same issue. There is no option for defining bifacial system with multiple orientations. If we choose unlimited sheds then we can't have multiple azimuth. And if we define multiple azimuth in shading scene then it selects "Several orientations" and we get the "not suited for bifacial" error.
