sapm_aoi_loss
(aoi, module, upper=None)¶ Deprecated since version 0.7: The sapm_aoi_loss function was deprecated in pvlib 0.7 and will be removed in 0.8. Use iam.sapm instead.
Determine the incidence angle modifier (IAM) using the SAPM model.
Parameters: Returns: iam (numeric) – The SAPM angle of incidence loss coefficient, termed F2 in [1].
Notes
The SAPM [1] traditionally does not define an upper limit on the AOI loss function and values slightly exceeding 1 may exist for moderate angles of incidence (15-40 degrees). However, users may consider imposing an upper limit of 1.
