Maharishi Solar Technology (MST) silicon plans emerge
MST to begin with 100 Metric Ton (MT) R&D Plant
Per Mr. Dev Raj with Maharishi Solar Technology (P) Ltd. (http://www.maharishisolar.com), MST decided to setup a Solar Grade Silicon manufacturing facility in India to address strong unmet local end demand for solar photovoltaic products. As a result of silicon shortages, Indian solar cell and module manufacturers are running at below capacity.
MST has obtained new technology for manufacturing Solar Grade Silicon which has yet to be commercialized. To start, MST will establish a research and development plant costing USD $15 million with 100 MT capacity. After the process is proven, MST plans to upgrade the plant to 1000 MT annual capacity with an additional investment of USD $45-50 million. The estimated Solar Grade Silicon production cost from this new process is about USD $50 per kilogram.
I wonder if this is the production cost or the expected equivalent silicon market price?
In the United States, while many folks have a holiday today, there is no second Christmas day holiday tradition. And this year, Boxing Day is misinterpreted as an excuse to see the new Rocky Balboa movie (see Rocky Balboa Review: Punch Drunk Love or the Official Movie Blog, ROCKY BALBOA BLOG).
On the IIC Photovoltaics page, there are updated Industry Overviews regarding Photovoltaics product and Photovoltaic Tooling manufacturers with production facilities in eastern Germany. These are good scorecards for recent photovoltaic production announcements in Germany.
Also, Reuters reports Taiwan's Motech to issue 18 mln shares via GDRs could raise about T$7 billion (US$214 million) based on the company’s current share price and depending on the value and pricing of the offering. Motech will use the proceeds to “purchase equipment and raw materials from abroad”. AE Polysilicon may well be a raw material from abroad.
Best Wishes for the Holidays to the readers and subscribers of GUNTHER Portfolio. Please visit my personal blog, Ed Gunther's Licht Blog, for my Christmas and New Years greeting card post.
Abstract submissions for papers from aspiring authors are due by January 29, 2007. Authors should preview and use the Online Abstract Submission form keeping in mind an abstract file upload is expected.
For further information, prospective authors should download and review the 22nd EU PVSEC Call for Papers.
I am thinking about topics for a paper myself. If I submit an abstract, I will post it to the blog, approved or not.
I look forward to visiting Milano for the second time. Why does every language like to rename places even when they use a similar alphabet? In my language scheme, local names would always be spelled and pronounced in the native tongue. Forget Milan and what’s up with the German name, Mailand? Sounds like an Italiano coffee drink. Ciao!
After Solar Power 2006, I was expecting to settle in and catch up on my article backlog. But on Halloween day, I received an email invitation from Joerg Duske, Strategy Advisor for Solarvalue AG, to attend their Press Conference at the 7. Forum Solarpraxis in Berlin. When I explained the travel budget was over spent for the year, Solarvalue offered to cover my flight and hotel expenses. As the proposal expanded to include a visit to TDR - Metalurgija in Ruše, Slovenia, I soon found myself on a flight (yes, coach!) bound for Graz, Austria, as the gateway to Maribor and final destination, Ruše, Slovenia.
I joined John Mott, Chief Operating Officer (COO), of Solarvalue Production d.d. for the taxi ride from Maribor to TDR in Ruše. After Mr. Mott asked the taxi driver to take us to “TDR”, there was an odd moment when the driver did not know the location of the TDR factory. The driver knew it by the full factory complex name, Tovarna dušika Ruše.
John Mott is an engineer who researched the production of SGS from metallurgical silicon (mg-Si) at Gaithersburg, Maryland, USA based Solarex Corporation in the 1980’s. Since Solarex, Mr. Mott has done extensive work in the field of silicon metal and composite materials outside of the photovoltaic space.
After initial discussions in the office with Mr. Vlado Hojnik, TDR’s Head of Development and Research, I was issued a cotton safety coat and a hard hat. Once the safety gear was donned, the TDR tour began with Mr. Hojnik leading John and myself to the 18MW (Megawatt) M1 arc furnace across from the main office building. M1 was active producing calcium carbide or CaC2 from a mixture of lime and coke at 2000 °C (degrees Celsius). I have visited and worked in factories, but this was my first visit to a heavy industry facility so I adopted a conservative approach to walking around, and I minded my tour guides.
While TDR was established in 1918, the M1 arc furnace was erected in the early 1960’s. M1 is about six stories or 60 feet (~18.29 meters) tall, including the electrodes, with a diameter of 32 feet (~9.75 meters). On the ground floor, I watched as calcium carbide was tapped or poured off from the M1 arc furnace. In my short video, you can see my steady camera hand shake when unexpected sparks fly as the calcium carbide is tapped.
The M1 furnace hearth and electrodes are located above on the first floor of the M1 building. The rattling noise you hear in the video is charge material feeding the hearth though mix tubes.
This is a professional video of M1 and other aspects of the TDR facility prepared for Solarvalue by the Dr. Klaus Heidler Solar Consulting team. Per the German soundtrack, the M1 furnace was being operated at 16MW for calcium carbide production during the video. Video quality has been downscaled per YouTube guidelines.
After the 12MW M5 arc furnace, Solarvalue plans to next convert M1 to metallurgical silicon production in 2008 requiring an additional investment of €10 million.
Behind M1 in the same building, there is an empty bay for an arc furnace. TDR sold this “M2” arc furnace last year to joint venture partner W&P Profil CEO Alojz Cajnko. At the time of the purchase, there was no plan to privatize TDR – Metalurgija, and it is conceivable M2 might find its way back home.
In Part 2, the TDR tour will continue with the M6 arc furnace and a literal look inside the M5 arc furnace and the metallurgical silicon production process.
GP Note: Solarvalue is reimbursing me for my flights to Berlin and Graz. I maintain independent editorial control over this article series, I have not been paid to write them, and I do not own any shares of Solarvalue AG stock.
The latest quotes posted by solar industry observer SolarBuzz show that the ASP for solar modules in Europe shrank slightly whereas it remained flat in the US. The sources indicated that solar cells from Taiwan makers had dropped to US$3.10-3.20 per watt from the previous US$3.30.
Given the solar module inventory issues in Germany, I believe Solarbuzz’s current blended ASP approach is overestimating prices and just plain not capturing 5% to 15% solar module price decreases. Solarbuzz acknowledges issues with their current methodology which includes solar modules ranging from 5 Watts to 315 Watts:
As a result, Solarbuzz will now move to showing its main index on this site as new retail price index for modules 125 Watts and above (even though Solarbuzz will, as usual, continue to capture prices across the power spectrum).
Since Solarbuzz surveys retail prices, the Solar Module Index is tabulating list prices and may not be uncovering price reductions in the distribution channel.
Please remember Solarvalue is traded on the Frankfurt Stock Exchange Open Market, the rough equivalent to Over-the-counter (OTC) in the United States.
The volume is below 10,000 shares with less then €100,000 in turnover.
Also, at the Berlin Press Conference, Solarvalue announced an increase in share capital of €115,000 from €450,000 was currently underway. I translate this to mean a secondary offering in US stock market jargon.
This spike in Solarvalue shares was pointed out to me by Klammrot, a frequent commenter on the Blog.
GP View: While I am impressed with Solarvalue's plans and team, Solarvalue is a very speculative investment. In the US stock market, I never invest in over the counter stocks.

Blue Square Energy hypes impurity enriched silicon solar cells
“Affordable, high-performance” silicon solar cells achieve “over” 12% efficiency
Beyond the quote in the previous post, Blue Square Energy launches website, there is not much more information on the Blue Square Energy (BSE) website regarding Bright Point silicon solar cells or impurity enriched silicon. The solar cell and module product pictures may or may not be representative of BSE products, and the copy on the website reads like classic marketing hype:
Blue Square Energy's silicon solar cells are currently available in two sizes: 200mm and 300mm. Our 300mm solar cell is the largest and most powerful silicon cell available in the market today and is found in many household tools and appliances.
I am very curious to see those “household tools and appliances” with 300mm (approximately 12 inch) solar cells! Perhaps this is a forward looking statement?
On the Cells and Modules product page, a round looking solar cell photo accompanies a square solar cell module (see photo above left). Although BSE’s 200mm and 300mm solar cell sizes match mainstream, round semiconductor wafers, BSE must realize round solar cells are passé and don’t match the fine Blue Square name? BSE makes a point of attacking existing photovoltaic technologies:
Moreover, current solar technologies — conventional silicon, thin film, amorphous — are too expensive and do not generate enough power to meet market demands.
November 7, 2006: Completion of DARPA Phase I Milestones.
March 20, 2006: Commercial Bright Point Solar Cells Achieves 12 percent efficiency.
May 27, 2005: BSE ships first 300mm solar cell.
April 10, 2005: BSE receives $13 million purchase order for silicon solar cells.
October 1, 2004: BSE signs lease on a 24,000 square foot production facility to manufacture solar cells from recycled silicon wafers.
The lack of detail on the BSE website raises a number of questions about Bright Point solar cells and impurity enriched silicon.
What is the physical geometry and thickness of the silicon solar cells?
Does BSE reprocess the scrap silicon semiconductor wafers in their original form?
Does BSE source or have plans to source some form of Solar Grade Silicon in addition to scrap wafers or is BSE’s ability to scale production limited by scrap wafer availability?
What specific DARPA (Defense Advanced Research Projects Agency) Phase I Milestones did BSE complete for the Very High Efficiency Solar Cell (VHESC) program? I have sent a request to DARPA for this detail.
While BSE claims to have “patented a clean solution”, with all these open questions, it is unclear if BSE is going back to the future with AstroPower style single crystal or Silicon Film based solar cell technologies or has BSE developed new manufacturing techniques to cast wafers or grow silicon ribbons. I would expect GE Solar Technologies, a General Electric Company (NYSE:GE) business, to be vigorous in defending the Intellectual Property obtained during their acquisition of AstroPower, Inc. from US Bankruptcy Court.
Jeffrey Barnett (President & CEO, Board of Directors) founded Blue Square Energy in April 2004 and serves as its president and Chief Executive Officer. He is responsible for setting the company's priorities and overseeing the research, development and manufacturing teams. He also directs every aspect of the company's fundraising and marketing activities. Prior to starting BSE, Mr. Barnett founded Market Path Associates, a strategy consultancy for emerging energy companies. He has previously held positions with AstroPower and Intel Corporation.
Mr. Barnett holds a B.S. degree in Electrical Engineering, with a semiconductor physics concentration, from Cornell University. He is president of the Associate Board for the St. Christopher's Foundation for Children and is active with the Cornell University Alumni Engineering Association, the American Cancer Society and Children's Hospital of Philadelphia. He has competed in the 2001 and 2002 New York City Marathons and numerous triathlons.
Besides Jeff Barnett as President, CEO, and the “Board of Directors”, the BSE team includes AstroPower alumni David Ford, Director, Research & Development, Jerry Culik, Director, Advanced Engineering, and Kevin Allison, Director, Business Development. John Pittman, Vice President, Manufacturing Operations, joined BSE in October 2006 from a similar role at Agere Systems, Inc. (NYSE:AGR). BSE has chosen not to disclose any board member besides Jeff Barnett.
Blue Square Energy has yet to disclose information regarding their existing investors, although BSE is open to new investors. Without disclosure and uncooperative with the press, I am left with speculation. Could Dr. Allen Barnett, Jeff Barnett’s father, be one of the secret investors in Blue Square Energy?
GP Note: There are numerous typos on the Blue Square Energy website. I corrected a few in the quotes to improve readability.
I was checking the Blog while waiting for a flight at San Jose Airport, and I noticed a spike in traffic regarding Blue Square Energy (BSE). Sure enough, the website update mentioned for late October has now arrived. I don't have much time before my flight, but they have a solar cell technology called Bright Point. Here is BSE's technology description:
Bright Point is Blue Square Energy’s line of high-efficiency solar cells. It utilizes low cost, abundantly available silicon that is enriched with impurities. While other solar companies spend much time and money removing impurities from silicon, we have found a way to use them to our advantage.
While impurities help to reduce the cost, it is our proprietary design and process that increases efficiency. Commercial-size samples have already demonstrated greater than 12 percent, and the company is quickly enhancing the technology to achieve market-leading efficiency. Proprietary manufacturing techniques mean the Bright Point line will soon have the most cost-efficient solar cells on the market.
BSE is offering 200mm and 300mm solar cells now with solar modules coming in 2007. I'll report on BSE in more detail this weekend. Time to board...
I look forward to switching to Blogger beta so I can exploit the tagging feature and expose this Blog’s content to new visitors and subscribers. But don’t expect this switch until the holidays; there is technology risk with the Blog conversion.
Summer Solar Rebate freeze highlights November 2006 NJCEP CORE Queues
NJCEP downplays summer freeze of solar rebates with success press release
If you read the recent press release from the New Jersey Board of Public Utilities (NJBPU), NEW JERSEY HIGHLIGHTS SUCCESS OF SOLAR MARKET, you might believe New Jersey’s Clean Energy Program™ (NJCEP, http://www.njcep.com) was a model of flawless execution in 2006. Likewise, the above chart of New Jersey Solar Installation Projects (CORE) by Quarter shows a slight drop in projects but an increase in Total kWp system capacity installed this summer 2006.
The Date of Approval Letter field in the latest CORE Queue <= 10kw Nov 22, 2006, shows no solar rebate applications were approved or checks issued from June 15, 2006, until September 29, 2006. The approvals for Q3/2006 were back end loaded to the absolute last business day of September 2006. The CORE Queue Less Than 10kWp has more than doubled since May 2006, but just over one third of the backlog has been addressed. Although the Date of Approval Letter field is not included in the CORE Queue Greater than 10kWp, any recent approvals occurred after the last CORE Queue release on September 15, 2006.
Talking with solar system installers and integrators at Solar Power 2006, I heard some scuttlebutt that the NJCEP program was being audited during the rebate freeze, allegedly because of “Pay to Play” concerns that have permeated New Jersey politics. I can only wonder what prompted the NJCEP to worry about New Jersey solar module shrinkage as reported in Gossip and Rumors from Solar Power 2006. Has there been a black market in rebated New Jersey solar modules?
I think NJCEP has done great work to promote solar and renewable energy in New Jersey, but they shouldn’t gloss over sustainable program growth issues with a press release.
