Put a speed con trol on your fan, thats what I do, i have it turned
down at start of day and keep turning it up as panel gets hotter. Cold
days dont seem to affect the heat output of mine, my best btus last
winter was the coldest day of year with a strong wind blowing.

That might point to a temperature controlled fan. Keep the air temperature
coming in from the panel at a predetermined point, or make it a difference
room, panel and outside. This might maximize the BTUs gathered in a day.

I would use multiwall that has the UV protectant. That is the basic need and
other types might cost more and be less widely available. It is my understanding
that when absorbers radiate IR it is longer wavelength. I doubt that the IR
blocks longer wavelength IR. If you have doubts, contact the GE vendor and ask
about solar thermal applications.
