With such different views,on Globe Warming, solar,wind,nuclear,carbon credits,transmition lines
Sierra Club,right or lelf, we should go down south to the desart in Mexico. Build nuclear power, that has no down sides. No CO2 and 60 years out of the box. Sell power to the southern states.
No Global Warming, no getting sued by the Seirra Club, no CARB or whatever requlations Do desaltation do and third party inspections.
For What half the dollar.

Dear Fellows and Friends

There is the true cost in loss of Carbon Credits by Gas and Oil
Finite Fossil Fuel use. The Cost also of relocating Island People
who have their ship coming in to their front door.

I am so tired of information like this which is bias and not including
the Global Climate Change science. Get real.

Sergei – remember that panel cost is only one part of the total cost. You’ve also got the inverter, cabling, installation and maintenance. The PV might be 15-25% of total system cost. Nevertheless, if Nanosolar are selling at below us$2 per watt peak, that is interesting.

That 16.4% is champion cell efficiency; panel efficiency is more like 11%.

Not sure what your “40% sunny days multiplied by 5″ means: please can you translate that into either full-load-hours per year, or capacity factor?

25 year life for printed CIGS? Hmm, maybe. Sounds optimistic, but we’ll see.

Nanosolar have been good at talking the talk, while their competitors, most notably First Solar, have been out shipping hundreds of megawatts. I hope Nanosolar, Solyndra, and the other new thin-film kids on the block, do get up to mass production soon: more competition has to be good.
