A set of documented functions for simulating the performance of photovoltaic energy systems.
The `pvlib.tracking.singleaxis` takes input parameters of ``apparent_zenith`` and ``apparent_azimuth``. Since the solar azimuth angle is not affected by refraction, this parameter name does not make sense. It is the only...
This issue is used to track past, present, and future deprecations and make the required follow-ups. Maintainers may update this issue whenever a feature is deprecated, renamed, or removed. If...
This is a demonstration of how we could remove the direct dependency on `pytz` and adopt the IANA-compliant standard-library solution `zoneinfo`, available since Python 3.9. This also leads to a...
https://github.com/pvlib/pvlib-python/blob/216386ef2f2fcdcaf1b3ecb5913abdf54e9eabaf/pvlib/iotools/psm3.py#L15 According to [NREL Developer](https://developer.nrel.gov/docs/solar/nsrdb/psm3-2-2-tmy-download/) & [pvlib](https://pvlib-python.readthedocs.io/en/v0.10.5/reference/generated/pvlib.iotools.get_psm3.html#pvlib.iotools.get_psm3) docs, this should be: `https://developer.nrel.gov//api/nsrdb/v2/solar/psm3-2-2-tmy-download.format?parameters`.

The output of the PVGIS iotools functions were modified in #2462 and #2470, which required reformatting the pvgis test inputs in a bit of a hacky way as pointed out...
During the deprecation of the ``parse_bsrn`` and ``parse_epw`` functions (#2466 and #2467), the parsing functionality was left in the corresponding private functions. This was done to quickly deprecate the parse...
Following on from discussions in #2234 and elsewhere, I thought it would help to create a single separate issue to track and discuss suggested further updates to that page. -...

**Is your feature request related to a problem? Please describe.** [Solar Position Documentation](https://pvlib-python.readthedocs.io/en/stable/reference/solarposition.html https://pvlib-python.readthedocs.io/en/stable/reference/generated/) recommends using the default solar position algorithm. Should we update to a faster algorithm given @AdamRJensen's...
