Half-cut modules cells strings in PVSOL

[Audrius]

Hello,

 

I'm making shading tests with PVSOL and trying to investigate how different shadings on different module cells reduces module and whole string parameters. I'm using Swiss Solar IBEX 144MHC-COSMOS 450 Wp modules. According to the literature half-cut modules with 3 bypass diodes celss are divided in to the 6 equal string. I tried to model these cases (3-7):

And I got PV curves, which shows 3 cell strings:

Please specify how PVSOL program is design. Does half-cut modules cells are divided in to the 6 cell string or 3 cell string like standart modules with full cells?

Hi Audrius,

thanks for your question.

Half-cell modules are divided into 6 cell areas and considered accordingly in the PV*SOL shading loss calculation.

Here is a post by Martin on this topic:

Does that answer your question?

Kind regards
