sunpeek.components.iam_methods.IAM_K50#

class sunpeek.components.iam_methods.IAM_K50(k50, plant=None)#

Bases: IAM_Method

Determine the IAM for given incidence angles aoi [degrees], using the ASHRAE formula, if only k50, the IAM value at an incidence angle of 50°, is given.

Parameters:: k50 (float) – IAM value at an incidence angle of 50°

Methods

`__init__`(k50[, plant])	A simple constructor that allows initialization from kwargs.
`add_component_attr`(name[, unit, minimum, ...])
`all_subclasses`([c])
`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].
`register_callback`(callback_type, func)
`set_component_attribute`(name, value, array_type)

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.
