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.
