v0.9.5.rst

v0.9.5 (anticipated March 2023)

Starting with this version, new releases are no longer distributed through the pvlib conda channel. We recommend conda users install from the conda-forge channel instead (see :ref:`installation`).

Deprecations

Enhancements

• Added the optional string_factor parameter to :py:func:`pvlib.snow.loss_townsend` (:issue:`1636`, :pull:`1653`)
• Added optional n_ar parameter to :py:func:`pvlib.iam.physical` to support an anti-reflective coating. (:issue:`1501`, :pull:`1616`)
• Added an optional model parameter to :py:func:`pvlib.bifacial.infinite_sheds.get_irradiance` and :py:func:`pvlib.bifacial.infinite_sheds.get_irradiance_poa` to enable use of the hay-davies sky diffuse irradiance model instead of the default isotropic model. (:pull:`1668`)
• Added :py:mod:`pvlib.financial` module with functions :py:func:`~pvlib.financial.lcoe`, :py:func:`~pvlib.financial.crf`, :py:func:`~pvlib.financial.nominal_to_real`, :py:func:`~pvlib.financial.real_to_nominal`, and :py:func:`~pvlib.financial.wacc` (:pull:`1687`)

Bug fixes

• Added a limit to :py:func:`pvlib.snow.loss_townsend` to guard against incorrect loss results for systems that are near the ground (:issue:`1636`, :pull:`1653`)
• Fixed incorrect mapping of requested parameters names when using the get_psm3 function. Also fixed the random reordering of the dataframe columns. (:issue:`1629`, :issue:`1647`, :pull:`1648`)
• When using utc_time_range with :py:func:`pvlib.iotools.read_ecmwf_macc`, the time index subset is now selected with nearest instead of before and after for consistency with cftime>=1.6.0. (:issue:`1609`, :pull:`1656`)
• :py:func:`~pvlib.ivtools.sdm.pvsyst_temperature_coeff` no longer raises a scipy deprecation warning (and is slightly more accurate) (:issue:`1644`, :pull:`1674`)

Testing

• Added Python 3.11 to test suite. (:pull:`1582`)
• Updated PSM3 test data files to match the new version 3.2.2 data returned by the PSM3 API (:issue:`1591`, :pull:`1652`)

Documentation

• Remove LGTM.com integration. (:issue:`1550`, :pull:`1651`)
• Added two examples demonstrating how :py:mod:`pvlib.financial` can be used (:pull:`1687`)

Benchmarking

• Added benchmarks for :py:mod:`pvlib.bifacial.infinite_sheds` (:pull:`1627`)

Requirements

• Removed unnecessary nose test requirement (:pull:`1637`)
