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!!!

The sens of energy (and other producers) is,

Other invention will not receive any help

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.
http://konarka.com ;) We're coming ;)
Can't find anything about Nanosolar actually selling their panels...
All I can find is a way to tell them you are a company interested in
playing dealer for them... And I can't find a list of dealers anywhere
either...
It seems to me they are very much in the planning phase still.
Same with those other thin film solar cell companies,
none of them seems to actually have anything for sale yet,
they're all just shouting how great they are but there's nothing
you can really get from them yet.
And those that do give some price estimates come up with prices
that, as Capthook calculated, are only profitable over the long run
of half a century or more. That's just not really exciting, is it?
regards,
Koen

Notice were it says, "Want to Buy Panels? We are presently already sold out for the next 12 months. We are working hard to scale our production capacity as fast as possible. Please sign up above to be notified of availability."
So I sigined up, but elsewhere it tells who did all the buying. US Dept of energy, the US military, and the largest power producer in the US. The entire inventory for the next twelve months.
The US taxpayer's dollars at work buying up the inventory so that the US taxpayer won't benefit. Sounds like typical greed at work.
@leno,
I have emailled Konaraka many times and didnt receive any information. All they have on the site is small time stuff. Can you throw us a bone and supply some details??

If you are talking about cost efficient energy in general...you will not like the answer. I pay 5 cents per 1,000 watthours here in the US and over 80% of our electricity here is produced by burning coal. This is why it is hard to compete for other alternative energy sources...this is a very low price when you figure it.
Bill ***EDIT Correction, I just checked my bill, we have had 2 huge rate increases this year I forgot about. I am now paying 9.5 cents per kilowatt hour. If they would allow more nuclear plants, this price would drop again. ***EDIT
Nuclear plants or horrible man completely and utterly there is no jobs created really... Other then construction contract labor nuclear is like ethanol you invest tell the city or town its going to create more jobs then once running it creates a whole 15 new jobs whoopdy doo!
And its worse then that because meltdowns will occur in nearly every plant at some time or another because they continue to run until something bad happens it seems to me this comment is not based off any facts just assumption but I will tell you it is worthless energy generation that is very very toxic! The threat is a real thing and it pollutes for thousands of years causing many problems and defects in any living thing. Not worth the savings you cannot put a price on life or quality of.
Never allow another nuclear plant to go up it is out right murder forget abortion this is mass murder for thousands of years you will kill everyone and everything...
Nanosolar will not be a viable solution for a couple years....
Scratch you ass until then or jump in heartiberlin's thread he started about DIY I think it is possible for the DIY to produce solar at home very cheap!!! The only thing we need is a common goal which we have but we all have to contribute hands on and if we do this we can make high efficiency cells at home for little cost!!! Yep I ain't bullshitting you with coils or magnets or perpetual motion .... This is a proven technology that works and we can make it more efficient together and anyone can make them it don't take a degree or lots of brain power or even time for that matter we can increase the efficiency of home made cells with simple tests at little cost!
Do you wanna join me ? Or are you to busy making coils and perpetual motion machines?
Please do not look at this post and walk away you are simply extending the period which it will take to find the solution.
