Use the :py:func:`sapm_effective_irradiance` function, the input
parameters, and ``self.module_parameters`` to calculate
effective irradiance.

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.

reference_irradiance : numeric, default 1000
    Reference irradiance by which to divide the input irradiance.

Returns
-------
effective_irradiance : numeric
    The SAPM effective irradiance.
