Vertical solar panels, east - west orientation, with bifacial modules

[Vladislav Iliev]

Dear all.

Interested in any and all information about modeling of Vertical solar panels, east - west orientation, with bifacial modules.

0.Best frame/ pitch layout

1.How to avoid errors with bicaial (irregular array) 

2. How to model into one scene panels facing  east and west. (Define facing directions and partitions)

Hello Vladislav Iliev,

To simulate a a vertical East West bifacial system in PVsyst you can as the error message either define the field type "unlimited sheds" (no need for a 3D scene since you here define the parameters such as the pitch etc.) or "Fixed tilt plane" where you need to define regular arrays in the 3D scene. For a East West system you have to define either East or West, and the backside of your bifacial panel will be facing the second orientation.

In the current version of PVsyst, Bifacial systems are limited to one orientation only and regular arrays. Please read the following PVsyst help page about the Bifacial model conditions and certain values in the advanced parameters that can be modified to be able to get around some of these constraints:
https://www.pvsyst.com/help/bifacial-conditions.htm

We also have a series of youtube tutorials of the model conditions and different ways to define your bifacial system:

In PVsyst version 8, coming out later this year, it will be possible to simulate a bifacial system with multiple orientations.

 

Kind regards,

[Vladislav Iliev]

Thank you, Linda.

Bifacial error is ressolved. Turns out it was matter of extending deviation on the pitch.

The matter of orientaiton:

If we import single orientataion vertical frames (PVCase generated-fixed tilt),

how can we redefine/be sure witch side ot the PV pannels is the face in the 3d scene?

Great!

In the Shading scene window, you have access to a list of your object and their characteristics (azimuth and tilt of your tables for example) by clicking Tools, List and management of objects (or by by clicking Ctrl G). Through this window you can also change these values and your 3D scene will adapt.
