v0.6.0

https://pvlib-python.readthedocs.io/en/v0.6.0/whatsnew.html

v0.6.0-alpha

This release contains most, but not all, of the features that will be released in 0.6.0. It reflects the status of pvlib python when its Journal of Open Source Software paper was accepted. See openjournals/joss-reviews#884

0.5.2

0.5.1

v0.5.1 (October 17, 2017)

API Changes

• pvsystem.v_from_i and pvsystem.i_from_v functions now accept
  resistance_series = 0 and/or resistance_shunt = numpy.inf as inputs
  (:issue:340)

Enhancements

• Improve clearsky.lookup_linke_turbidity speed. (:issue:368)
• Ideal devices supported in single diode model, e.g.,
  resistance_series = 0 and/or resistance_shunt = numpy.inf (:issue:340)
• pvsystem.v_from_i and pvsystem.i_from_v computations for near ideal
  devices are more numerically stable. However, very, very near ideal
  resistance_series and/or resistance_shunt may still cause issues with the
  implicit solver (:issue:340)

Bug fixes

• Remove condition causing Overflow warning from clearsky.haurwitz
  (:issue:363)
• modelchain.basic_chain now correctly passes 'solar_position_method'
  arg to solarposition.get_solarposition (:issue:370)
• Fixed: Variables and Symbols extra references not available <https://github.com/pvlib/pvlib-python/issues/380>_ (:issue:380)
• Removed unnecessary calculations of alpha_prime in spa.solar_position_numpy
  and spa.solar_position_loop (:issue:366)
• Fixed args mismatch for solarposition.pyephem call
  from solarposition.get_solarposition with method='pyephem'
  arg to solarposition.get_solarposition (:issue:370)
• ModelChain.prepare_inputs and ModelChain.complete_irradiance now
  correctly pass the 'solar_position_method' argument to
  solarposition.get_solarposition (:issue:377)
• Fixed usage of inplace parameter for tmy._recolumn (:issue:342)

Documentation

• Doc string of modelchain.basic_chain was updated to describe args
  more accurately. (:issue:370)
• Doc strings of singlediode, pvsystem.v_from_i, and pvsystem.i_from_v
  were updated to describe acceptable input arg ranges. (:issue:340)

Testing

• Changed test for clearsky.haurwitz to operate on zenith angles
• Significant new test cases added for pvsystem.v_from_i and
  pvsystem.i_from_v (:issue:340)

0.5.0

v0.5.0 (August 11, 2017)

API Changes

• Removed parameter w from _calc_d (:issue:344)
• SingleAxisTracker.get_aoi and SingleAxisTracker.get_irradiance
  now require surface_zenith and surface_azimuth (:issue:351)
• Changes calculation of the Incidence Angle Modifier to return 0
  instead of np.nan for angles >= 90°. This improves the calculation of
  effective irradiance close to sunrise and sunset. (:issue:338)
• Change the default ModelChain orientation strategy from
  'south_at_latitude_tilt' to None. (:issue:290)

Bug fixes

• Method of multi-inheritance has changed to make it possible to use kwargs in
  the parent classes of LocalizedPVSystem and LocalizedSingleAxisTracker
  (:issue:330)
• Fix the __repr__ method of ModelChain, crashing when
  orientation_strategy is set to 'None' (:issue:352)
• Fix the ModelChain's angle of incidence calculation for
  SingleAxisTracker objects (:issue:351)
• Fix issue with ForecastModel.cloud_cover_to_transmittance_linear method of
  forecast.py ignoring 'offset' parameter. (:issue:343)

Enhancements

• Added default values to docstrings of all functions (:issue:336)
• Added analytical method that calculates solar azimuth angle (:issue:291)

Documentation

• Added ModelChain documentation page
• Added nbsphinx to documentation build configuration.
• Added a pull request template file (:issue:354)

Testing

• Added explicit tests for aoi and aoi_projection functions.
• Update test of ModelChain.__repr__ to take in account :issue:352
• Added a test for solar_azimuth_analytical function.
