pvlib.pvsystem.calcparams_desoto

[vanpnguyen]

Could someone help explain what cause the error and how to fix it?

I want to output Voc at a defined effective_irradiance and temp_cell.

Thank you,

pvlib.__version__ ?

Ah, I think I see your problem. You are calling pvlib.pvsystem.calcparams_desoto with the API from #471, but your pvlib package will have the old API for that function. You can either go back to the old function call style (using the module_parameters dict or figure out how to copy the new pvsystem.py into your package. Sorry I can't be of more help with that last option.

You can google around for hints on installing the latest version from github in a way that fits your workflow. pip install <link to gh repo> is probably the easiest.

@vanpnguyen seems like in the future this issue might be better asked at pvlib-python Google group thanks!
