home power had some pics in an article I think. Definatly recall swing a conventional cannopy and the "store" flat roof of a gas station retrofitted. A ppa project developer at last years sp trade show had pics in his booth. Sorry I don't recall his name. Bp did 30 really nice cannopy arrays

Hi Jay, My experience was the exact opposite with Unisolar triple-junction structural standing seam systems in 1996 and megawatts of Unisolar from 2003 to 2007. My Unisolar tests and installations exceeded PVWATTS kWh estimates by approx 5% (PVWATTS uses crystalline PV temperature coefficient).

Joel, I've been either a participant or observer of the PV field/industry as long as most greybeards in the field. And ever since my entry in the RE biz in the 1970s, the promise from the touters of thin films has been: 1) their product was going to revolutionize the industry, 2) their product

HI Doug, Thanks, If memory serves, they were replaced, inverters were changed and the results were the same. Most of my other experience is with battery based applications and I just haven't seen any advantage. I have seen no real lack of performance, but not the advantages that others

Hi Marco, I'm moving this over to RE-Markets before I get my Send button punched. I agree and am a crystalline guy for now. But if just 50% of the announced thin film factories come on line and only half of the survivors match First Solar's cost/price/profit, then other thin film wannabees a go
