API field
Module IAM profile
The module's measured angular response
Unit ° / factor
What it is
The module's own incidence-angle table: a list of incidence angles in degrees and, for each, the fraction of light the module accepts compared with light at normal incidence. When the incidence-angle method in the Model tab is set to use the module's curve, this table is what it uses.
Typical values and how to get it
The PAN file table, or a measurement per IEC 61853-2. If not given: no module IAM profile. The IAM step's automatic choice then uses Fresnel with an anti-reflective coating.
