sunpeek.components.iam_methods.get_iam_ASHRAE(aoi, b)#

Determines the incidence angle modifier using the ASHRAE transmission model, using :py:mod:pvlib.

Parameters:

aoi (pd.Series) – The angle of incidence (AOI) between the normal vector of the collector plane and the sun-beam vector, as pint (unit aware) pandas Series. Angles of NaN will result in NaN.
b (float, default 0.05) – A parameter to adjust the incidence angle modifier as a function of angle of incidence. Typical values are on the order of 0.05 to 0.2 [3].

Returns:

A unit-aware, dimensionless pandas Series containing the IAM values.

Return type:

pd.Series
