The parameter that characterizes losses due to reflection is called the incidence angle modifier (or IAM for short in English). The amount reflected and thus the losses depend on the angle of incidence (AOI) between the normal vector of the module and the vector of the solar ray..

The figure below shows the IAM profile for normal glass and AR-coated glass and compares it to the ASHRAE parametrization. It shows that the ASHRAE parametrization underestimates the IAM value at medium angles (30 to 60°) and overestimates them over these values. In the past, the IAM function has. .
The first step is to calculate the angle of refraction (θ r) using Snell’s law. θ r = arcsin (1 n sin (θ)), where n is the index of refraction of the cover glass and the 1 in the numerator is the index of refraction of the air. The incident angle modifier at an angle, θ, is a ratio between the. .
The incidence effect (IAM, for “Incidence Angle Modifier”) corresponds to the decrease of the irradiance really reaching the PV cells’ surface, with respect to irradiance under normal incidence, due to reflections increasing with the incidence angle. FIAM = 1 – β x (1/Cos i – 1), with i = incidence. .
Incidence Angle Modifier (IAM) coefficients evaluate the response of a PV module to light coming from various angles. IEC 61853-2:2016 defines an indoor test method for characterization of the IAM values of a PV device with respect to the angle of incidence (AOI) by measuring short-circuit current. .
ermal collectors. More than 200 glass types from leading manufacturers have been measured and ertified to date. Despite the certification having been explicitly developed for solar thermal applications, it became widely used in the PV module industry, even though the results are not transferable. .
