Jörn,
If parameter 16 is set to a positive value between 0 and
1, then it sets tau-alpha for all angles of incidence. If parameter
16 is set to a negative number, the incidence angle modifier routine
inside Type94 will be enabled and the absolute value of parameter 16
sets the magnitude of tau-alpha at a normal angle of incidence
(according to the "More" button for parameter 16 of Type94).
Best,
david

Dear all!
Is it true that par16
(tau-alpha) is only used for the thermal model to calculate
the cell temperature? This is how I read the source code. If
I change the parameter to e.g. 0.1 the array power is not
changed (while setting par7 and 8 to zero). Isn’t there an
IA dependence of the cell power?
Thank you for your help
Jörn
