@ayushjariyal I feel like this bug should have been caught in the tests. Are you willing to add a check to this test to verify that all intended columns have been mapped?

@cwhanse, does this test also need to be updated to check for the intended columns?

This test already includes 'solar_zenith', but maybe I'm misunderstanding the test workflow:

@cwhanse, does this test also need to be updated to check for the intended columns?

In both cases I think the better answer is no.

The error (zenith in place of solar_zenith) is in a map from pvlib names to PSM3 names. The results of that mapping are not passed to other pvlib functions; they are only checked for a correct index. Tthe test structure (for all of iotools, I think, and to a large extent all of pvlib) does not enforce pvlib's parameter nomenclature except when calling another pvlib function. That kind of enforcement strikes me as complicated, probably undesirable, and certainly, well beyond the scope of this PR.

I vote to only fix the name and thank the contributor.

@cwhanse, I agree. Thanks for the clarification.

@ayushjariyal I don't think we need a note in the whatsnew for this fix, and you're already in the list of contributors. So this is done I think.

Thanks for working on this @ayushjariyal
Can we change the title of this PR to something like (suggestion) "Change zenith to solar_zenith in psm3 variable map"? Might make it easier to find if needed for future reference

Thanks @ayushjariyal!
