My question is, how are these shingles attached, and what do you figure -- in relation to time -- it takes to install them? I would surely consider them as an option to customers in my roof replacement business. @ Admin

For the 50-200 watt figure, I relied on <a href="http://www.thisoldhouse.com/toh/article/0,,1205726-2,00.html" rel="nofollow">This Old House Magazine</a> for some of my research, thinking it was credible since it ran on PBS for so many years. At the end of the article, it says, "Thanks to Noah Kaye, Solar Energy Industries, www.seia.org" You can also find the 200 watt claim at <a href="http://solar.calfinder.com/library/solar-energy/solar-products/solar-shingles" rel="nofollow">Calfinder.</a> In doing further research, I think the 50 to 200 watts per shingle claim is puffing, but that a solar slate tile like the <a href="http://www.atlantisenergy.com/index.htm" rel="nofollow">Atlantis Sunslate</a> could probably achieve 200 watts per tile--see <a href="http://www.solarserver.de/solarmagazin/solar-report_0206_e.html rel="nofollow">the Solarserver Forum</a>. The silicon is sandwiched between glass panels similar to a traditional PV panel--the only difference is that it's a roofing material instead of an add-on panel. It has the same weight disadvantages as PV panels but at least it looks better. If you still think the 50-200 watt numbers are incorrect, why don't you contact SEIA and express the same concerns you've expressed here? Please feel free to return with any follow-up comments you might have after hearing their side of the story, and I'll correct my post as necessary. @Deep Patel: I was initially put off by these numbers, too, because last time I checked, thin film was running only 15-20% efficient at capturing the sun’s energy, in contrast to traditional glass PV panels, which are about 30% efficient.

Typically pv roofing shingles generate less watts per square foot than traditional solar panels. Also there are no roofing shingles that produce 200watts each can you please let me know the make and model number of that extremely high output roofing shingle?
