The REST2 clear-sky model is developed by Chris Gueymard, who has expressed serious interest in contributing this to pvlib. Notably, the REST2 model is used to generate the NSRDB, so...

As mentioned by @wholmgren in https://github.com/pvlib/pvlib-python/issues/2326#issuecomment-2685685954, the new `pvlib.iotools.psm4` functions have long, very similar docstrings, which may be improved by using computed docstrings: > If we go with the separate...

I published a comprehensive temperature model that pulls together handling of dynamics and radiative losses at EU-PVSEC 2024. The paper title doesn't mention a new model, but I got a...

In my [solarspatialtools ](https://github.com/jranalli/solarspatialtools) library, I made an [implementation](https://solarspatialtools.readthedocs.io/en/stable/demos/synthetic_clouds_demo.html) of [Lave et al's](https://dx.doi.org/10.1109/PVSC.2017.8366378) synthetic irradiance approach based on stacked multi-scale random cloud fields. I wanted to offer to contribute it...

**Is your feature request related to a problem? Please describe.** I find `pytz` to be somewhat confusing and cumbersome. Since Python 3.9, `pytz` can be replaced by the standard library's...

pvlib includes several models for estimating the spectral mismatch including different technologies, that are basically designed for conventional PV. They depend on the parameters that mostly affects to the incoming...

#943 adds methods `run_model_from_poa` and `run_model_from_effective_irradiance`. The docstrings would be improved with examples. ~~#943 also added several `ModelChain` constants: `WEATHER_KEYS`, `POA_DATA_KEYS`, `TEMPERATURE_KEYS`. These keys should have docstrings.~~
