I hadn't heard of ASHRAE before, so that is useful to know about.
Okay, so I am assuming a steady-state is achieved as I am considering average values over the course of a year, I have worked out net thermal power transmitted by radiation, and I have worked out heat gain by convection, however...
Thanks for the reply.
My scenario is a little more complicated than that unfortunately; I am looking at designing a Concentrating Solar Collector, and need to know what the theoretical Energy transfer to an internal fluid would be.

I'm sorry if this has been covered already, but I want to calculate the expected temperature rise of a length of pipe in the sun, and following the above linked thread instructions gave me a temperature rise much smaller than I was expecting.
So I have used the formula Q = a *...
