Bifacial design

[juhee]

Hello.

I wonder how to 3D desgin at bifacial module.

when I use that option I heard I can only use unlimited shed. But nearshading cannot use unlimited shed.

so I want to know how can I use 3D CAD option in bifacial module

thank you

In the present time the bifacial model of PVsyst is indeed limited to shed-like or tracking with horizontal axis installations, sufficiently large for neglecting the edge effects on the sides of ths system, as well as in front and behind it.

However you can define a 3D scene (in sheds or trackers), and if you (and PVsyst) judge that this matches these hypothesis, PVsyst will allow to use this installation as basis.

However for the bi-facial calcuation, it will construct a dummy "unlimited sheds" installation, as similar as possible to your effective installation.

Please carefully read the help "Project design > Bifacial Systems > Bifacial systems procedure".
