Per @lmicheli recommendation, I suggest we add the dynamic albedo calculation as described [here](https://www.sciencedirect.com/science/article/pii/S2667113122000043). I am up for taking the task of adding it to pvlib, but I would like...

We have developed a method for determining parameter values for the PVsyst single diode model using IEC 61853-1 matrix measurements. The method produces useful fits on a range of [IEC...

**Is your feature request related to a problem? Please describe.** There is not an easy way to obtain POA transpositions for dual-axis tracker systems. **Describe the solution you'd like** Have...

**Describe the bug** I'm trying to call `pvlib.solarposition.spa_python` with arrays for time, latitudes and longitudes. It works fine by default, but I get an error if I use `how='numba'` with...

**Describe the bug** Yet another typo at https://github.com/pvlib/pvlib-python/blob/599c5d97abd6ed8ba2dec92999cc40ee05083fb7/pvlib/modelchain.py#L1573 that we can leave for the EU PVPMC workshop in case anybody wants to learn to contribute. **To Reproduce** This typo is...

**Describe the bug** `pvlib.atmosphere.first_solar_spectral_correction` was deprecated in v0.10.0 but it doesn't have an scheduled removal version. No issues or PRs open for it. **To Reproduce** See https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.atmosphere.first_solar_spectral_correction.html And tests for...

I found that instantiating a ModelChain can batch simulate PV for multiple different Locations and different PVsystems. My task is like this, I have meteorological data, radiation data and PV...
