I have a client who is interested in PV panels on a metal roof (to be installed). I found this film while surfing around, and wondered if anyone has used it (or something similar), or knew anything about it.

What film?
Thin Film PV

"Thin film" refers to the technology used to make the photocells. AFAIK, there is no "film" available that can be readily applied to existing surfaces, if that's what you're thinking.

Note that they don't show the laminate actually being applied to the roofing.

There are a couple photovoltaic/shingle integrated systems available. I posted a link after reading an article a couple months ago, but don't remember the names

Client wants a metal roof, and I don't know if I want to trust a pv panel to do double dutyhttp://www.tvwsolar.com

Head on over to the JLC Forums and find Bill Robinson in the Exterior Details area (he's the mod). He has some significant experience that might help you.

I'm wondering how often there is a hail storm in your area?
Any idea if PV panels increase home owner's policy?

Rare that it hails here, but it happens... the insurance is a good question.http://www.tvwsolar.com

I think that is part of the beauty of the thin film ... flexible ... doesn't break w/ routine impact of the baseball, hail, etc. The down side is tht it may be somewhat less efficient than the 'high tech' rigid/glazed type panels.
IIRC it's somewhere between 1/3 and 1/2 as efficient.

The efficiency is what I'm concerned about. It's a sketchy situation to begin with. 10 - 12 pitch, middle of roof cross gable, big tree across the street to the southwest.Thanks for the linkshttp://www.tvwsolar.com

Yeah, pay your money ... take your choice. Time and place for everything. Nice low profile and durable.
We are using it on carports where I work. Great stuff! It is applied to e.g. standard metal roofing using adhesive. It's about 1/16" thick maybe 3/32. We're installing lots of this stuff in the SoCal desert. Don't know a lot about the comparitive efficiency, but if you want to keep it thin and light and low profile, this is a great way to go.
I was watching the green channel and a guy in SF used it. He also ran pex tubing under the metal for solar water heating. That's a 3 in 1 system!
Don't try that in the desert though, it would probably melt the pex! ;-)

I'll check at the office. This is one of many many energy projects, so the manufacturer doesn't stick in my mind. I'll get back to you.
Thanks, it'd be nice to be on the inside track<G>http://www.tvwsolar.com

I installed a system on a standing-seam metal roof, the panels were amorphous silicon, made to fit in the fields 'tween the seams. Used shooters w/rubber washers to screw the panels to the roof (there were areas at the top and bottom of the panels w/o silicon, OK to screw through). Used a gutter (imagine a low-profile molding) across the ridge for the wiring.
Worked great. It was a net-metering system.

Thanks CAP, do you have a brand name?http://www.tvwsolar.com

Uni-Solar...seemed like a good product.
Here's a paper on that very product by UW. Nice to ahve more than the manufacturers info:

I'll post a couple of pictures, once I figure out how.

It is peel and stick for metal roof applications.
