SixParameterSolver ouputs different than SAM GUI

Hello,
I am running a trade study on combinations of solar panels and inverters that satisfy a given power requirement. Roughly a hundred of the panel models I want to use are not included in the SAM module database, and I was hoping to use PySAM to create inputs, rather than having to input them all into the GUI using the "CEC Performance Model with User Entered Specifications" menu.
I think the Sixparsolve class is the right one to do this ( nrel-pysam.readthedocs.io/en/master/modules/SixParsolve.html ), but when I input values from a module currently in the SAM database, I get different values than what is displayed on the GUI.
Take the Panasonic panel with model number VBHN340SA17 as an example. When I provide the inputs as user entered specifications, I get matching results (see attached screenshot).
When I input the following code:
I get different numbers:

params_outputs =  Is this expected behavior, or am I doing something wrong?

Thanks,
Warren L. Pinkard

Hi Warren,

I had to do a bit of digging to sort this out. Thank you for providing the Python script -- that made my job a bit easier.

Anyway, the SAM user interface sets Tref = 25 rather than to Tnoct. If you make that change in your Python code you should get the same results as SAM.

The Tnoct parameter is used for cell temperature calculations when you simulate the PV system with the pvsamv1 module. It is not used when you generate parameters with the 6parsolve module.

Best regards,
Paul.

That is exactly what I needed, thanks so much Paul!
