Bifacial Modeling for the Carport System

[PranavK]

Hi @Michele Oliosi and @Linda Thoren,

I am working on a carport system and trying to model the Bifaciality correctly. 

The snip of the system and the bifacial modelling from PVsyst are attached below. I have 6 (majority) and 4 modules in portrait orientation in a carport table. But, the bifacial system definition shows the pitch and shed total width as 2.28m, which is only the length of a single module.

When I try to model the system as per the actual array, i.e., 6 modules in portrait, making the shed total width 13.72 m and the effective pitch between the two arrays approx. 19.92m, the system definition brings back the shed total width to length of 1 module, i.e. 2.28m.

Am I modelling the bifacial system correctly or is there something I am missing?

Hi,

The issue most likely comes from the definition in the 3D scene, if each panel is defined individually rather than as a table. As the red message in this window indicates (though not very clear so this can indeed be confusing), you can play with the shed's parameters as you like for parametric analysis, though the simulation will be done with the defined values in the orientations window and the table size in the 3D scene, only the pitch and number of rows can be overwritten. 

To solve this, you need to define tables rather than individual modules. If you are importing the tables from another 3D software, make sure you indeed draw full tables (as the alternative to the right), and PVsyst then normally will fill the total area with individual modules and the area will be considered a table.
