What is the the thin film solar roof shingles efficiency of harnessing the solar energy?
Sustainable Energy for healthy grandchildren
Powerlight based in Berkeley CA has a roofing system that achieves from 100 to 150 W / m^2. see

They recently merged with SunPower who makes 14 % efficient panels.
NanoSolar, just starting production has a thin film process but I don't know their efficiency. Their cost / Watt may be the lowest.
Ovonics / ECD has a lower efficiency flexible material once shown on NOVA but with a cost/Watt equivalent to panels.

Hi,
After read the question and Valuable replay of "EnergyFred",I totally agree with him.

Thin film solar is getting alot of press lately. The reason is that CIGS technology is getting better and it has also broke the buck ($1.00 per watt). New methods of coating the thin film so as to absorb infrared is being funded hevily. Their prediction is to reach 15% plus in the near future.You may want to look at a metal roof with that sticky label type thin film that just peals and sticks. That way you take your deductions on a 70 year metal roof and just lick and stick that UNi Solar stuff on. It takes up more roof space, but if your metal roof is dark brown or black - you'll never see the solar laminate. Cheap, looks good, works great in the high heat, and you get a cheap metal roof which is typically expensive. In my state, there's a 30% discount.
Hello,
Thank you for your info!
