Allan,

Solar Design Associates have the most experience here in the US with these
types of installations. They like to hold on to their secrets, so I don't
know how much you can learn from them without hiring them.

Steve Strong and BP Solar did a lot of work with Kawneer glazing systems and
got several of the BP laminates accepted to work with their standard mullion
systems. I would extend your search beyond Atlantis because I think that
these BP products could be a better fit.

Glass on glass ASE-300 laminates with clear encapsulants look great in these
types of installations. It is important to get as large a laminate as
possible because the laminate extrusions tend to be very expensive and labor
intensive. A glazing company, who specializes in installing atria, should be
used for the mullion installation.

The tough part is getting laminates approved for overhead glazing. This can
be handled with the local jurisdiction by examining the construction of the
laminates (tempered glass with a 30 mil encapsulant between the sheets, for
instance), but if they hesitate and want to see clear-cut building
certifications, there may not be any manufacturers, with UL-listed products
for this application, that are also certified for overhead glazing.

Good luck.

Bill.

Fellow Wrenches,
We recently received an initial inquiry from a general contractor who has a
client planning a very upscale residence who wants to incorporate PV cells
laminated onto a glass roof substrate over an atrium/entryway. The total
roof will be about 1800 sq. feet, and is to be grid-intertied.

We haven't done this before, and we are gathering early info to get our foot
in the door and provide some workable initial options. Our initial research
directed us to Atlantis Energy Systems as the PV/roof manufacturer, and we
were referred to Tibor Fischl and BASS Renewable Energy Resources of San
Francisco as an installer, either turnkey or of the roof/BIPV. We have no
problem working with an outside supplier/installer of the roofing who will
provide warranty on the roof as well as the BIPV. Seems like they have no
trouble with our providing BOS and local support.

So, these questions, please:
--General advice and guidance, links and resources, etc. on a project of
this type;
--Feedback and advice, references and experiences about these two companies
(on-list or off-list to allan at positiveenergysolar.com; use your discretion);
--Other companies that excel in this specialty;
--Other approaches that we should consider.

Thanks in advance for good advice as usual,
Allan at Positive Energy
