pvlib.pvsystem.sapm_spectral_loss#
- pvlib.pvsystem.sapm_spectral_loss(airmass_absolute, module)#
Deprecated since version 0.10.0: The spectral_factor_sapm function was deprecated in pvlib 0.10.0 and will be removed soon. Use pvlib.spectrum.spectral_factor_sapm instead.
Calculates the SAPM spectral loss coefficient, F1.
- Parameters
airmass_absolute (numeric) – Absolute airmass
module (dict-like) – A dict, Series, or DataFrame defining the SAPM performance parameters. See the
sapm()
notes section for more details.
- Returns
F1 (numeric) – The SAPM spectral loss coefficient.
Notes
nan airmass values will result in 0 output.
