Jibi,
It would help to know which Type you are asking about.
Transmittance absorptance products are typically obtained by
multiplying the transmittance and the absorptance of a transparent
material together. Depending on which component you are talking
about you may being asked for the transmittance-absorptance
product at a normal incidence angle or you may be being asked to
give some kind of hemispherical average.
kind regards,
David

Hi
I was trying to validate my TRNSYS results using the mathematical description provided.I would like to know how the transmittance-absorptance product was calculated.I did simulation for a flat-plate collector and a PVT system.It seems the value of transmittance and absorptance is not provided anywhere.
Thanks in advance
Jibi
