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 *Report issues & contribute:* * https://github.com/pvlib/pvlib-python *v0.9.4 Highlights:* * Fitting <https://pvlib-python.readthedocs.io/en/stable/reference/pv_modeling/generate...> and prediction <https://pvlib-python.readthedocs.io/en/stable/reference/pv_modeling/generate...> functions for the ADR PV efficiency model, along with several gallery examples <https://pvlib-python.readthedocs.io/en/stable/gallery/index.html#adr-model-f...> . * An extension of the Faiman temperature model <https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.temp...> that includes a radiative loss term. * Efficient direct <https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.iam....> and diffuse <https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.iam....> IAM models based on the Schlick approximation to the Fresnel equations. * A convenience function <https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.irra...> to calculate one of DNI, DHI, GHI from the other two. * The Hay-Davies <https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.irra...> 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.ivto...> for extracting the basic characteristics of an I-V curve. * There were several new contributors. *Thank you for using pvlib python!* -- Mark Mikofski, PhD (2005) *Fiat Lux*
