Are you in a freezing climate? If yes, how do plan to keep such a small volume
(1/2") from freezing?

If no, are you just capturing the heat with the collector and "exchanging" it?
What type of heat exchanger?  Single or double wall?  If you're using a glycol
heat transfer fluid you can't use a single wall exchanger (code).

You want low-iron, tempered glass with a high transmittance. Are you insulating
the collector?
