Bifacial System in PVSyst 8.02

[Zaenul01]

Dear PVSyst Team,

I am currently trying to simulate a bifacial system in the PV System configuration. However, when I open the Bifacial System settings, the 3D shading scene does not appear to be connected to the bifacial configuration.

In the 3D Shading section, I have already created and added the 3D shading scene. However, it is still not recognized in the Bifacial System window.

Could you please assist me in resolving this issue? Is there any step that I might have missed which causes the 3D shading scene not to appear in the bifacial system settings?

For your reference, I have attached screenshots of both the Near Shading and Bifacial System sections.

Thank you for your support.

Hi,

The bifacial model presently available in PVsyst is based on a simplified 2-dimensional representation, with similar assumptions as the "unlimited sheds" or “unlimited Trackers” PVsyst simplified calculation. This approximate calculation may be extended to a 3D scene, provided that this 3D scene is sufficiently well represented by the "Unlimited sheds or trackers".

Thus, simply use the option "Use unlimited sheds 2D-model" in your second print screen. 

You find a tutorial about the bifacial model conditions for the 3D scene below:
