Start-Up Sells Solar Panels at Lower-Than-Usual Cost

SAN JOSE, Calif. — Nanosolar, a heavily financed Silicon Valley start-up whose backers include Google’s co-founders, plans to announce Tuesday that it has begun selling its innovative solar panels, which are made using a technique that is being held out as the future of solar power manufacturing.

The company, which has raised $150 million and built a 200,000-square-foot factory here, is developing a new manufacturing process that “prints” photovoltaic material on aluminum backing, a process the company says will reduce the manufacturing cost of the basic photovoltaic module by more than 80 percent.

Nanosolar, which recently hired a top manufacturing executive from I.B.M., said that it had orders for its first 18 months of manufacturing capacity. The photovoltaic panels will be made in Silicon Valley and in a second plant in Germany.

While many photovoltaic start-up companies are concentrating on increasing the efficiency with which their systems convert sunlight, Nanosolar has focused on lowering the manufacturing cost. Its process is akin to a large printing press, rather than the usual semiconductor manufacturing techniques that deposit thin films on silicon wafers.

Nanosolar’s founder and chief executive, Martin Roscheisen, claims to be the first solar panel manufacturer to be able to profitably sell solar panels for less than $1 a watt. That is the price at which solar energy becomes less expensive than coal.

“With a $1-per-watt panel,” he said, “it is possible to build $2-per-watt systems.”

According to the Energy Department, building a new coal plant costs about $2.1 a watt, plus the cost of fuel and emissions, he said.

The first Nanosolar panels are destined for a one-megawatt solar plant to be installed in Germany on a former landfill owned by a waste management company. The plant, being developed by Beck Energy, is expected to initially supply electrical power for about 400 homes.

The company chose to build its plant in southern San Jose, news that was cheered by local development officials. Much of the microelectronics industry created here has moved to Asia and new factories are a rare commodity in Silicon Valley.

Google will soon rule the world. I checked out their website. Pretty amazing. Their first megawatt is going to a german power plant and 12 months production is already sold out

Production panel #2 is now being sold on Ebay as a collector item.

Solar energy for $1 per watt...on a flexible foil that can be cut to any shape, that is a quantum leap.

Available and shipping as of Dec 18 2007......pretty incredible.

Freaking Google.

The website says they are sold out for the next 12 months!

These prices are at a wholesale volume anyway. When the dealers get ahold of them the panels will be back up to $5 a watt anyway.

Bajabus - 12-19-2007 at 08:16 PM

The more large wholesale customers they have the better pricing will be to consumers.

They have repeatedly said that they are committed to delivering power panels with an end cost of approx 1 dollar per watt. Right now production costs for them are about 30 cents per watt and this is only the first iteration of their proprietary machinery!

I do not think it true that pricing will go up to 4-5 dollars per watt when they catch up with production

The implications for peak power production are staggering.

So is this company selling stock? My be a great opportunity at hand.

Bajabus - 12-19-2007 at 11:20 PM

They are funded up the wazoo by Googles 2 founders who provided "angel money" to seed the concept and some very prestigious investment houses. It is a private held corp and on the investor page it says they are not accepting capital right now.

Solar at these prices is the kernel to a new energy economy...there are two fields that can produce tomorrows energy for zero air pollution...solar and nuclear. Neither will ever power transportation in the next 100 years...hope I am wrong about solar.
So what is the power system for transportion needed for zero destruction of our world...hint ...something that already powers our research in boundaries

My guess is the same thing the "dollar" is made of- cellulose. I like the subtle hints sprinkeld throughout your post.:P

Optimism and Caution

MrBillM - 12-20-2007 at 11:47 AM

During the last Twenty years or so, we have witnessed numerous introductions of "Revolutionary" advances in Solar Technology only to have those products either fail or not make it to market. TI had one such technology that was promoted heavily and written about in one publication after another until it quietly disappeared pre-market.

We are reminded by the Kyocera KC-120 Fiasco that even proven technology can fail due to poor design or manufacturing failures and those flaws may not be apparent for years into usage.

If ultimately successful, this would be good news, but we may not know for many years.

What's the KC-120 fiasco? I don't know anything about it.

Yeah, me neither. I am considering buying one.

Roberto - 12-20-2007 at 04:58 PM

I have three, had them for five years. No problems.

Al G - 12-20-2007 at 06:02 PM

MrBillm...you are the eternal pessimist, and in this case not a character flaw. It is most assuredly a good thing. Keeps you from ever failing...something I do often. I am a eternal optimism a character flaw that I have used to my advantage many times and a few disadvantages...I have managed to get to a reasonable point in life as I am sure you have. From my point of view the future looks bright and promising...possibly brilliant. It is good to have that sort of thing going on in ones life. Your posts makes me feel there are many things politically and philosophically we may have in common. Hope for a spectacular tomorrow may not be one of them...Merry Christmas MrBill:)

I can hardly wait for my Nanosolar powered electric vehicle. :smug:

I wonder when they will start delivery?:lol::O

KC-120s

MrBillM - 12-20-2007 at 09:06 PM

Kyocera built THOUSANDS of defective KC-120s over a period of a number of years. The defects didn't show up until the panels had been in use for at least a few years. In my case, the units were in place five years before the charge rate deteriorated. For some of my neighbors, the period was at least three years. Kyocera corrected the problem with a design change on the later units. Since I had Six built during the defect period and Four built after, it was easy to look at the cell junctions and see the difference in manufacturing process.

Luckily the Full warranty period is long and to Kyocera's credit, they have handled the defect returns with excellent customer service. Even after KC-120 production ended and they were replaced by the more expensive KC-130. Upon being notified and being given the Serial numbers of the panels, they ship replacement KC-130s prepaid at no charge and pay the freight on the defective unit returns.

The point I was making, though, is that they built and sold these units for years before their defects became known. If the warranty period was shorter or the manufacturer less solvent, it would have been tough luck. As I've said before (with computer tech), being on the leading edge of new technology can leave you badly cut.

Could you post some pictures illustrating the differences? Since I have three, I would like to check them

Pictures ?

MrBillM - 12-20-2007 at 10:00 PM

The earlier model (defective) panels have all been returned, but I could take a pic in the next few days of the area to look at on the newer panels. There is a notable difference of the width of the metallic band at the cell junctions.

As an indicator of the period involved, the latest of my defective panels had a mfg date (6-2001) and serial no: 2001.6 01632B1761

The later 120s I own built AFTER the correction had a coding of: 2002.10 03X32B0191
