Plexiglas glazing and FRta

Hello,

I want to simulate a solar thermal panel, but I do not have the FRta coefficient. My solar panel uses a Plexiglas glazing. What value should I use?


thank you

Hello,

I'm not sure what value of the FRta coefficient you should use for your solar water heating collector. You might try finding a collector similar to yours in the SRCC database to choose a coefficient.
