v0.4.5 (2024-12-11)

Breaking Change

• Changed function signature of pvdeg.degradation.degradation.

  • New function takes spectra_df instead of spectra and wavelengths disparate arguments.

  Also takes conditions_df instead of disparate rh_module and temp_module pandas series.

  spectra_df : pd.DataFrame

  front or rear irradiance data in dataframe format

  • data: Spectral irradiance values for each wavelength [W/m^2/nm].
  • index: pd.DateTimeIndex
  • columns: Wavelengths as floats (e.g., 280, 300, etc.) [nm].

  Example:

  timestamp                 280     300     320     340     360     380     400

  conditions_df : pd.DataFrame, optional

  Environmental conditions including temperature and relative humidity.

  • index: pd.DateTimeIndex

  • columns: (required)

    • "temperature" [°C or K]
    • "relative_humidity" [%]

  Example:

  timestamp                 temperature  relative_humidity
  2021-03-09 10:00:00         298.0               45.0
