(aoi, iam_model='physical')[source]¶ Determine the incidence angle modifier using the method specified by
iam_model
.Parameters for the selected IAM model are expected to be in
Array.module_parameters
. Default parameters are available for the ‘physical’, ‘ashrae’ and ‘martin_ruiz’ models.- Parameters
aoi (numeric) – The angle of incidence in degrees.
aoi_model (string, default 'physical') – The IAM model to be used. Valid strings are ‘physical’, ‘ashrae’, ‘martin_ruiz’ and ‘sapm’.
- Returns
iam (numeric) – The AOI modifier.
