This is a minor release. We recommend all users of v0.6.0 upgrade to this release.
Python 2.7 support will end on June 1, 2019. Releases made after this date will require Python 3. (:issue:`501`)
Minimum pandas requirement bumped 0.14.0=>0.15.0
- Created the
pvlib.iotoolssubpackage. (:issue:`29`, :issue:`261`) - Deprecated
tmy,tmy.readtmy2andtmy.readtmy3; they will be removed in v0.7. Use the new :py:func:`pvlib.iotools.read_tmy2` and :py:func:`pvlib.iotools.read_tmy3` instead. (:issue:`261`) - Added keyword argument
horizonto :func:`~pvlib.solarposition.pyephem` and :func:`~pvlib.solarposition.calc_time` with default value'+0:00'. (:issue:`588`) - Add max_airmass keyword argument to :py:func:`pvlib.irradiance.disc`. Default value (max_airmass=12) is consistent with polynomial fit in original paper describing the model. This change may result in different output of functions that use the disc Kn calculation for times when input zenith angles approach 90 degrees. This includes :py:func:`pvlib.irradiance.dirint` and :py:func:`pvlib.irradiance.dirindex` when min_cos_zenith and max_zenith kwargs are used, as well as :py:func:`pvlib.irradiance.gti_dirint`. (:issue:`450`)
- Changed key names for components returned from :py:func:`pvlib.clearsky.detect_clearsky`. (:issue:`596`)
- Changed function name from pvlib.solarposition.get_rise_set_transit (deprecated) to :py:func:`pvlib.solarposition.sun_rise_set_transit_spa. `sun_rise_set_transit_spa` requires time input to be localized to the specified latitude/longitude. (:issue:`316`)
- Created new bifacial section for pvfactors limited implementation (:issue:`421`)
- Add :py:func:`~pvlib.solarposition.sun_rise_set_transit_ephem`to calculate sunrise, sunset and transit times using pyephem (:issue:`114`)
- Add geometric functions for sunrise, sunset, and sun transit times, :func:`~pvlib.solarposition.sun_rise_set_transit_geometric` (:issue:`114`)
- Add Location class method :py:func:`~pvlib.location.Location.get_sun_rise_set_transit`
- Created :py:func:`pvlib.iotools.read_srml` and
pvlib.iotools.read_srml_month_from_solardatto read University of Oregon Solar Radiation Monitoring Laboratory data. (:issue:`589`) - Created :py:func:`pvlib.iotools.read_surfrad` to read NOAA SURFRAD data. (:issue:`590`)
- Created :py:func:`pvlib.iotools.read_midc` and :py:func:`pvlib.iotools.read_midc_raw_data_from_nrel` to read NREL MIDC data. (:issue:`601`)
- Created :py:func:`pvlib.iotools.get_ecmwf_macc` and :py:func:`pvlib.iotools.read_ecmwf_macc` to get and read ECMWF MACC data. (:issue:`602`)
- Use HRRR modeled surface temperature values instead of inferring from isobaric values and modeled wind speed instead of inferring from gust. (:issue:`604`)
- Change :py:func:`!pvlib.pvsystem.sapm_spectral_loss` to avoid numpy warning.
- Add warning message when :py:func:`pvlib.spa` is reloaded. (:issue:`401`)
- Add option for :py:func:`pvlib.irradiance.disc` to use relative airmass by supplying pressure=None. (:issue:`449`)
- Created :py:func:`pvlib.pvsystem.pvsyst_celltemp` to implement PVsyst's cell temperature model. (:issue:`552`)
- Created :py:func:`pvlib.bifacial.pvfactors_timeseries` to use open-source pvfactors package to calculate back surface irradiance (:issue:`421`)
- Add PVSystem class method :py:func:`~pvlib.pvsystem.PVSystem.pvsyst_celltemp` (:issue:`633`)
- Add :py:func:`pvlib.irradiance.clearsky_index` to calculate clear-sky index from measured GHI and modeled clear-sky GHI. (:issue:`551`)
- Fix when building documentation using Matplotlib 3.0 or greater.
- ~pvlib.spa.calculate_deltat: Fix constant coefficient of the polynomial expression for years >= 1860 and < 1900, fix year 2050 which was returning 0. (:issue:`600`)
- Fix and improve :func:`~pvlib.solarposition.hour_angle` (:issue:`598`)
- Fix error in :func:`pvlib.clearsky.detect_clearsky` (:issue:`506`)
- Fix documentation errors when using IPython >= 7.0.
- Fix error in :func:`pvlib.modelchain.ModelChain.infer_spectral_model` (:issue:`619`)
- Fix error in
pvlib.spawhen using Python 3.7 on some platforms. - Fix error in :func:`pvlib.irradiance._delta_kt_prime_dirint` (:issue:`637`). The error affects the first and last values of DNI calculated by the function :func:`pvlib.irradiance.dirint`
- Fix errors on Python 2.7 and Numpy 1.6. (:issue:`642`)
- Replace deprecated np.asscalar with array.item(). (:issue:`642`)
- Add test for :func:`~pvlib.solarposition.hour_angle` (:issue:`597`)
- Update tests to be compatible with pytest 4.0. (:issue:`623`)
- Add tests for :py:func:`pvlib.bifacial.pvfactors_timeseries` implementation (:issue:`421`)
