Revisions

  • January 21, 2018 by Filip Jorissen:
    Revised azimuth angle computation. See #753.
  • January 20, 2017 by Filip Jorissen:
    Changed computation of Tenv. See issue #623.
  • September 22, 2016 by Filip Jorissen:
    Reworked implementation such that we use Annex 60 baseclasses.
  • March 25, 2016 by Filip Jorissen:
    Reworked radSol implementation to use RealInputs instead of weaBus. This simplifies translation and interpretation.
  • February 10, 2015 by Filip Jorissen:
    Adjusted implementation for grouping of solar calculations.
