Dear Pythonistas and solar power enthusiasts,

The maintainers are happy to announce a new release of pvlib python: software for simulating performance of photovoltaic solar energy systems.

*See what's new for v0.9.4:* ** *https://pvlib-python.readthedocs.io/en/stable/whatsnew.html

*Releases are available from PyPI and the conda-forge channel:* * https://pypi.org/project/pvlib/ * https://anaconda.org/conda-forge/pvlib and https://anaconda.org/conda-forge/pvlib-python

*Read the Documentation:* * https://pvlib-python.readthedocs.io/en/stable/index.html

*v0.9.4 Highlights:* * Fitting https://pvlib-python.readthedocs.io/en/stable/reference/pv_modeling/generated/pvlib.pvarray.fit_pvefficiency_adr.html#pvlib.pvarray.fit_pvefficiency_adr and prediction https://pvlib-python.readthedocs.io/en/stable/reference/pv_modeling/generated/pvlib.pvarray.pvefficiency_adr.html#pvlib.pvarray.pvefficiency_adr functions for the ADR PV efficiency model, along with several gallery examples https://pvlib-python.readthedocs.io/en/stable/gallery/index.html#adr-model-for-pv-module-efficiency . * An extension of the Faiman temperature model https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.temperature.faiman_rad.html#pvlib.temperature.faiman_rad that includes a radiative loss term. * Efficient direct https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.iam.schlick.html#pvlib.iam.schlick and diffuse https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.iam.schlick_diffuse.html#pvlib.iam.schlick_diffuse IAM models based on the Schlick approximation to the Fresnel equations. * A convenience function https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.irradiance.complete_irradiance.html#pvlib.irradiance.complete_irradiance to calculate one of DNI, DHI, GHI from the other two. * The Hay-Davies https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.irradiance.haydavies.html#pvlib.irradiance.haydavies transposition model can now return individual components in addition to global tilted irradiance. * An implementation of ASTM E1036 https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.ivtools.utils.astm_e1036.html#pvlib.ivtools.utils.astm_e1036 for extracting the basic characteristics of an I-V curve. * There were several new contributors.

*Thank you for using pvlib python!*
