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
Reference irradiance by which to divide the input irradiance.
Returns: effective_irradiance : numeric
The SAPM effective irradiance.
