Defining PV tables in 3D scene which with unequal number of modules on each row

[JamesLenton]

Hi guys,

I am attempting to define tables in the 3D scene which are 3 in portrait but in some cases are 'missing a module(s). The string length is 28 and the site was filled with these 3 table sizes for 1, 2, and 3 strings. This leads to the 1 and 2 string tables having non equal number of modules on each row. 

 

Is there an easy way to do this in PVsyst, without defining a small table and then adding 1 or 2 modules by themselves?

Any suggestions are appreciated!

Dear James,

 

Could you please share a screenshot of your system? It's unclear why some modules are missing.

Hi Muhammed,

 

Sorry I can't share that. It is where smaller tables have been used to fill the more narrow parts of the available land - and the table sizes that were used for this are shown in the image I posted. I think it was so the table sizes were in 1, 2, and 3 strings.

Dear James,

 

Can you explain your procedure for creating this table so I can understand what went wrong?

I think my use of the work 'missing' is confusing things. The actual design was made this way, and I am trying to replicate it. And I am wondering if were is an easy way of doing this.

Thanks, James.

Dear James,

I understand what you want to do. You need to create a polygonal PV plane.

 

Then, right-click to delete one or more modules when you position the mouse over a PV module.

Hi Muhammed,

Thank you so much for your help! I just didn't look hard enough to find that tool!

Have a good weekend,

James.

Hi Muhammed,

 

I have added the polygonal fields to my 3D scene, however I am now getting an error with the bifacial system definition: "not all you table widths are identical - system not suited for bifacial 2D model computation".

 

Can you not define bifacial modules for polygonal PV planes?

 

Best,

James.

Dear James,

 

Polygonal tables are not suitable for bifacial systems.

 

I suggest using a full table, but be aware that your shading calculation might be slightly higher than the actual value.

Thanks for updating me. Is this something that will change as PVsyst version 8 is released?

When can we expect more information on version 8?

Best,

James.

Dear James,

 

This feature is planned for version 8.

Our community will receive information about the version 8 soons.
