Partitioning

[PVsystUser]

PVsyst V6.2.16

I have a 2P project, half cell with 28 modules in series (string length). I can define partitioning in 3 different ways but the results of shading animation is not the same and also the iso diagram is not the same. I included the screen shots below for all there methods. Please advise on which method is the best method to use for partitioning.

Hi,

There is no object management window in PVsyst 6, so I assume you are using a more recent version. Which version are you using ? 
I have tried to see if solution 1 had a bug in version 8.0.19, but everything works fine.

You are probably correct that solution 2 may have an issue sometimes. The zone tool is rather old and sometimes misbehaves. Solutions 1 and 3 should be equivalent.

You are right, it was a typo, my version 7.2.

Do you have any idea why my shading scene in method one does not show proper shading animation? I don't even see the dotted lines that show partitioning is done, but the shading factor table looks good for a backtracking which is 0 everywhere. I afraid that it produces zero because shading is not working at all and not because of correct partitioning.

I see ! 

I just remembered that in this version (7.2) there is a bug for trackers. In the object management window, the number of partitions is not affected to the right variable. It is connected to the size of the partitions instead which in turn makes it not work. Please use option 3 or update the PVsyst version.
