*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!*
