Hi All,
I just viewed 2 videoclips from Nanosolar.com

Here they are:

http://www.nanosolar.com/

And watch the 2 videoclips which are linked at the right buttom from this page:

http://www.nanosolar.com/rolltoroll.htm


It seems they now have very nice and cheaply to manufature roll printing solar cells.

I hope this will put enough final competition to the other solar cellmanufacturers,so we finally
can get soon really cheap  solar cells, that would only be around 1 US$ or less per Watt.

I think, then solar energy will be installed in many more locations !

Regards, Stefan.

P.S: If anybody can find out, what kind of PN semiconductor surface they use and
what kind of foil metal and transparent layer they are using,
please post it here.

Maybe one could design this also as a do it yourself solar cell kit,
as it looks not very complicated.
If one could design a kit that can print these solar cells at home
with at least 5 % efficiency with standard chemicals onto alufoil
or other cheap metal foils, this would be a great achievement.

Many thanks.

Regards, Stefan.

This is not nanosolar.com , but related and pretty simular:

Great video !

Just let your meters spin backwards and make money this way ! ;)

Here is some news from Nanosolar.com

Hopefully they will soon ship the cells.
I really want a few...

Nice I really hope this solarcell will cost less then current available.

Hi People ,
 i got a few months ago a couple of informations during a talk with two German Physicians developing Solar Cells about Nanosolar .
They are developing thin sheet cells as well , and they are planing a new production for a coupl of million bucks . Because I am actually also involved a little bit in the solar business because of my own business ,also there was a big report in Bild der Wissenschaft last jeahr about Nano solar and the amazing Vita story of Chris Ebersb?cher ex CEO of Nanosolar .
I asked this two guys what they are doing if nanosolar are comming soon on market with printed cells for less then 1 ? production costs per Watt .They said then the most of the Solarcell Produktion Industrie is " Pleite" means bankrupt.
But nobody in the Industrie beliefs it , and nobody ever had any Nano cell in teir hands .They said its all big fake . I dont belief it ,i think this two Physics gona loose a hell of a lot of money in the next couple of month .
How can you explain that they searching engineers in luckenwalde for the new production factory , and also you can?t buy any shares of Nanosolar .
Well we will see very soon , i hope they come very soon and very cheep with their products

30 cents per watt eh!

Does anyone know what the most cost efficient energy is? Cuz I'm pretty sure that 30 cents/W has to be pretty close to being just that.

There is a lot more to solar than just cost per watt. 

Also very important is watts per square meter.  The printed solar cells have very low efficiencies. 

Another important question is how fast do these already low efficiencies degrade upon solar exposure?

Indeed you are right, but this company alone have without doubt impressed a number of high profile investors.

It would be a stupendous waste of time and resources if they could not 'step up to the mound' with what they deem the '3rd Wave of Solar Power' developement.

I for one hope they can deliver what they promise.

UPDATE: They´re already selling the cells and they´re actually sold out for the next 12 months!

Has anybody bought any?

What´s the price per watt?

I want them!!!

Nanosolar is promising.  Current 'standard panel' (silicon based) costs have dropped to about $8 a watt.  A basic 2KW home system currently runs about $18,000 + install ($21,000 total).  So that's $16,000 in panels and $2,000 in BOS (balance of system) costs.
And that size system will only generate about 50% of the avg. U.S. households daily consumption.
 
At $.12 a KW current electricity costs and average annual consumption:

25KW per day x 365 = 9,125 KW x $.12 = $1095 annual electric bill
Now replace 50% of that with a $21,000 2KW system: $550 annual pv production
$21,000/$550 = 42 years to pay the system off to break-even.
However - this figure doesn't account for possible electricity price increases in the future - but they have been relatively stable.
Figure 35 years.
BUT if you can take advantage of a Federal/State incentives - you can reduce that to maybe 25 years payoff time. (depends on the state)

If the $1 a watt is realized - this WOULD open up the solar industry to the many who can't come up with the large $$ outlay now - only to take 25-30 years to recoup the investment.

$1 a watt would translate into the same system costing: $9,000
Half the cost and half the break-even time.
10-15 years to recoup your costs - and then 15 years of free, stable power makes it very appealing.

As has been mentioned - the Nanosolar panels are low efficiency - requiring a larger area of panels installed.  This is not an option readily available in many places: apartments, low-sun horizons etc.
And just what their panels specs is hard to say:

"Technical Data Sheet? We presently share product data sheets only under Non-Disclosure Agreement with qualified volume customers. This is so we can extend the period of protection for certain proprietary features we have developed."

There are several other companies pursing the same type of process that have stated production in the next 2-3 yrs.

http://www.avasolar.com/  is an example.

All in all - the future is looking brighter all the time for solar.  But the watt/meter still needs to increase and the durability of these new panels hasn't been tested for extended periods.

And the sun still shines only 1/2 the time.  And without net-metering, storing that electricity is inefficient and expensive.

The U.S. has implemented mandatory net-metering rules in all states effective next year.
The problem is - their isn't a firm definition of 'net-metering'.
Many states are implementing a 'Time of use' structure - meaning your electric bill could actually go UP after spending $20,000 on a solar!
We ran the numbers.....
Hopefully this will be addressed in the future.  But at the pace the US Congress moves... in could take at least 5 or 10 more years!!!

If the people PAY this prized
it is not need to produce cheaper one.
The sens of energy (and other producers) is,
to earn money, solong it is possibel.
/that is an normal human thinking(?)/

Other invention will not receive any help
to offer that devices

Controlled introduction of solar into the US market advised:

http://www.greentechmedia.com/articles/feeding-in-renewable-energy-breakthroughs-5556.html

 That means the average consumer will NEVER benefit from solar as it is slowly introduced into the marketplace in a controlled manner by the Government. This keeps control of profits as well.

quoted in the article: "Setting an initial feed-in rate at $0.15 per killowatt hour for 20 years for solar projects..."

How about that. A twenty year price control.
