|Scott and his prototype CPVC collector.|
I did a side by side performance test of Scott's design compared to the established DIY collector design that uses copper riser tubes spaced about 6 inches apart with thicker grooved aluminum fins to transfer heat into the riser tubes. In this test, the CPVC design performed within 5% of the copper/alum collector, which I think is very good.

I would be most interested in hearing your thoughts on the comparison and which collector you think would work out for your situation.
Full details on the performance and stagnation tests, construction, IR pictures, etc. for the two collectors...
