SCHOTT and WACKER set up joint venture to produce solar wafers

  • SCHOTT WACKER Solar to produce multicrystalline silicon wafers for solar cells
  • 370 million euros investment to create at least
  • Production start-up in 2007
  • Capacity expansion phased to reach 1 gigawatt per year by 2012

Mainz / Munich, August 2, 2007 – SCHOTT Solar, a 100 percent subsidiary of the worldwide SCHOTT group, and WACKER Chemie AG plan to set up two joint ventures to produce and market silicon wafers for solar applications. SCHOTT and WACKER signed a related agreement today. Over the next years, the two partners plan to invest a total of 370 million euros in facilities in Jena (Thuringia) and Alzenau (Bavaria), creating at least 700 new jobs at these German sites. The project is subject to approval by the German and European authorities. The joint venture – SCHOTT WACKER Solar GmbH – is scheduled to start operations this year. It will produce multicrystalline silicon ingots and wafers, the starting material for solar cells. Solar-wafer production capacity is set to expand in stages, reaching about one gigawatt/year by 2012. This will make the joint venture one of the world’s five largest solar-wafer manufacturers.

 Glory Silicon Energy Purchases DSS450 Furnaces -- $171 Million Order Merrimack, NH, USA — July 31, 2007

GT Solar Incorporated, one of the major providers of manufacturing equipment and turnkey manufacturing solutions to the photovoltaic (PV)  industry, announced today that it has signed a $171 million dollar contract with Glory Silicon Energy Co., Ltd., of JiangSu, China for GT’s new and more efficient DSS450 furnaces for the production of multi-crystalline silicon ingots.  The contract is the largest single DSS furnace contract in GT Solar’s history and will include deliveries over the next two years.  The order will equip what is projected to be one of the largest wafer factories in the world – about 1500MW annually. 
 
 
The DSS450 (Directional Solidification System) furnace is new to GT Solar’s equipment line.  It is similar to the DSS240, but can grow larger silicon ingots than GT’s DSS240 furnace, with an average ingot weight of 400kg (or customized up to 450kg), and can deliver 30% more output than GT’s DSS240 furnace.
 
GT Solar Incorporated President and CEO, Thomas Zarrella, said:  “Glory Silicon Energy Co. will be a major player in the growth of the global solar industry.  Glory’s order for our DSS450 furnaces over the next two years is one more indication of the significant growth of the solar industry in China.”
 
GT Solar Vice President for Asia, Jeff Ford, said:  “This is the second major order for GT Solar’s new DSS450 furnaces that produce larger silicon ingots.  It’s a key part of Glory’s plan to jumpstart its production.”
 
Glory Silicon Energy Co., Ltd. President, Wang LuBao, said:  “We have turned to GT Solar for its DSS450 furnaces because they are the most technologically advanced on the market today.  We look forward to using GT’s equipment to produce quality solar wafers for the growing solar marketplace worldwide.”

Energy-hungry China warms to solar water PDF Print E-mail

DEZHOU, China (Reuters) - Dusty Dezhou was relegated to the footnotes of Chinese history for centuries, known mainly as the place where a Filipino king died.

Now, Huang Ming hopes hot water will help put it on the map.

His company has earned a fortune manufacturing solar heaters, relatively low-tech rooftop devices which capture the sun's energy to provide water for baths and washing and are at the forefront of a renewable energy drive.

At least 30 million Chinese households now have one and last year the country accounted for around 80 percent of the world market, said Eric Martinot, visiting scholar at Beijing's Tsinghua University. "We are at 15 to 20 percent annual growth and I don't see that slowing down."

Solar heating of Hot water Using a Vaccum PDF Print E-mail

 Himin Solar Energy Group of China has developed solar hot water heating.  The technology uses a vaccuum space much like a thermos works.  In this case the outside and inside are made of clear glass.  The water on the inside keeps getting hotter as long as the sun is shinning.  Even in the winter the water gets hot due to the vaccumm keeping the heat from the water from escaping thus causing the water to keep getting hotter.

Photovoltaic Capacity Valuation Methods PDF Print E-mail

 Washington, D.C., United States [RenewableEnergyWorld.com]

As utilities work to meet electricity demand, especially during peak summer days, examining the relationship between demand and solar photovoltaic (PV) output can be of significant value to the utility industry. Over the years, energy researchers have developed different statistical methods for calculating this relationship. However, there is no consensus across the utility or solar industries on a statistical method for calculating the capacity value of PV or its practical use in electricity markets and utility planning.

Sahara Forest Project to Generate Fresh Water, Solar Power and Crops in African Desert PDF Print E-mail
Saturday, 12 December 2009 23:56

 Here is an article by Leonora Oppenheim.  The amazing thing here is not so much the amazing use of technology used to grow crops, but the amazing fact that what is totally clean energy is used to generate a carbon based fuel that will simply add to global warming.  The propensity of  business to twist something elegant into something stupidly destructive is the real amazement.

Can you imagine being able to produce enough water in the Sahara to grow crops there? Can you imagine harnessing sufficient quantities of solar power to supply electricity to cities in Africa and cities in Europe? Can you imagine producing a sustainable bio-fuel that doesn’t impact on world food supplies? Charlie PatonMichael Pawlynand Bill Watts can and what’s more they can imagine all these happening in the same place at the same time.
