sunpeek.components.iam_methods.IAM_ASHRAE

class sunpeek.components.iam_methods.IAM_ASHRAE(b, plant=None)

Bases: IAM_Method

Determine the IAM for given incidence angles aoi [degrees], using the ASHRAE formula.

Parameters:

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 [3].

define_component_attrs()
get_component_attribute(name)
get_default_unit(name)	Return default unit of a class attribute defined as ComponentParam.
get_iam(aoi, **kwargs)	Determines the IAM for given incidence angles aoi [degrees] and difference between solar and collector azimuth angle [degrees].

classmethod get_default_unit(name)

Return default unit of a class attribute defined as ComponentParam.

Return type:

str

get_iam(aoi, **kwargs)

Determines the IAM for given incidence angles aoi [degrees] and difference between solar and collector azimuth angle [degrees].

Parameters:

• aoi (pd.Series) – The angle of incidence (AOI) between the module normal vector and the sun-beam vector, as pint (unit aware) pandas Series. Angles of NaN will result in NaN.

• azimuth_diff (pd.Series) – The difference between solar and collector azimuth angle, as pint (unit aware) pandas Series.
