Now that I read this, I think I should have suggested following the type of ghi instead of solar_zenith. Sorry for the confusion @jason-rpkt .

Output is a DataFrame when solar_zenith is a Series.
solar_zenith is the one that sets the output type.

Output is a ``pandas.DataFrame`` when ``ghi`` is a Series,
otherwise it is a dict of ``numpy.ndarray``.
