The collector sits flat to the roof and looks exactly like a regular Velux skylight. There are no visible plumbing connections. They use the same flashing system on the collectors as they do on their skylights.
It seems like this look might be a lot more acceptable to a picky HOA?
The SRCC performance ratings are comparable to other good flat plate collectors.
|Mixed skylights and solar collectors.|
