sapm_effective_irradiance
(poa_direct, poa_diffuse, airmass_absolute, aoi, module, reference_irradiance=1000)[source]¶ Calculates the SAPM effective irradiance using the SAPM spectral loss and SAPM angle of incidence loss functions.
- Parameters
poa_direct (numeric) – The direct irradiance incident upon the module.
poa_diffuse (numeric) – The diffuse irradiance incident on module.
airmass_absolute (numeric) – Absolute airmass.
aoi (numeric) – Angle of incidence in degrees.
module (dict-like) – A dict, Series, or DataFrame defining the SAPM performance parameters. See the
sapm()
notes section for more details.reference_irradiance (numeric, default 1000) – Reference irradiance by which to divide the input irradiance.
- Returns
effective_irradiance (numeric) – The SAPM effective irradiance.
