Thanks, Kurt & Ian~ The Dawn Solar arrangement makes me think of a similar looking setup from American Solar: http://americansolar.com/product-solar-roof.htm
The American Solar setup heats air which they claim can then heat water. Hmm. My inner geek suspects that both of these systems would yield only low temperature rise...which would be OK for pool heating or even for space heating...but for DHW? Hmm. Both of these systems remind me of unglazed swimming pool collectors. Glass is old school, low tech, breakable, and there's that nagging low R-value problem. Even so, glass really has some marvelous properties. The "greenhouse effect" makes glass behave similar to a selective surface. Ian's note about the Velux integrated collectors is also appreciated. There are some excellent how to videos on the Velux website which may be of interest to other List members. Anyone in the SW Rockies who might be interested in pooling an order for Velux gear in order to save freight costs may contact me off list.
