Southfield, MI - Schreiner ProTech is now marketing an array of specialized labels and identification-preparation equipment for solar panels and components. Drawing on its extensive solar product experience in Europe, Schreiner is nowaggressively seeking new customers in North America for its UL/CSA-approved solar labeling solutions.{pagebreak}The manufacturing of photovoltaic (PV) solar modules makes exacting demands of marking technology materials and systems.  Labels used for production control, track-and-trace, branding, and as power-rating and nameplates, must be able to permanently withstand extreme UV rays and weather conditions-many for the life of the PV module. In addition, they have to meet a number of legal requirements, such as UL and CSA standards.Today, every single solar PV module is marked with an individual code for production control purposes and traceability. The code is applied in a clearly visible location at the front of the module, and must retain its legibility-even after years of exposure to UV radiation. Schreiner ProTech has developed an Embedded Label for this application. It is TTR-printable, dimensionally stable, and is applied directly to the ethylene-vinyl-acetate (EVA) sheet or a bus-bar of the solar module.Schreiner Power Labels have to comply with exacting legal requirements. They mostly

The notion of Space-Based Solar Power (SBSP) is not new. There has long been talk of 24-hour-a-day solar power beamed from space via microwave to any point on earth. However, a new company named Space Energy, Inc. believes it well placed to develop SBSP satellites to generate and transmit electricity to receivers on the Earth's surface. To do this, the company plans to create and launch a prototype satellite into low earth orbit (LEO).There's only one hitch: this concept is based on as yet unproven technology.{pagebreak}SBSP was mooted over 40 years ago by scientist Dr. Peter Glaser. Since then, in response to periodic energy crises, the plan has been re-evaluated from time to time by the U.S. Department of Energy, NASA, major aerospace companies and countries such as Japan and India.Solar power satellites are massive arrays of photovoltaic panels assembled in orbit, which utilise microwave radio waves to transmit solar power to large receiving antennas on Earth. The resulting power can either supplement, or be a substitute for, conventional electricity sources.The advantage of putting large solar collectors in geosynchronous Earth orbit (GEO), about 36,000 kilometres (22,500 miles) above Earth, is that it uses the constant and unobstructed output of the

Scientists at Berkeley University (USA) have this week released research revealing that alternative raw materials, such as iron pyrite - or Fool's Gold - could offer a far cheaper alternative to silicon for solar panel manufacturers.The rapid growth of the global solar market has been repeatedly hampered by shortages of silicon, which is used to make the semiconductors found in many solar panels. But now Berkeley researchers have identified 23 promising semiconductors that could be used as an effective alternative. They concluded that 12 of the alternatives are more abundant than silicon, while nine would be cheaper to manufacture.{pagebreak}"We started looking at new materials because people often assume solar will be the dominant energy source of the future," said Cyrus Wadia of the Lawrence Berkeley National Laboratory, who led the research. "But current solar technology may not get us there in a time frame that is meaningful, if at all. We must turn our attention back to basic science research if we are to solve the problem."Currently, the most viable commercial alternative to silicon-based solar panels are so-called thin film panels, typically made from cadmium telluride or copper indium gallium selenide (CIGS). However, critics claim that resources of these raw

24. February 2009. Raphael van Hövell is one of the first system operators in Germany to finance their PV installations with the new tariff for private consumers under the German Renewable Energy Sources Act (EEG). With the EEG amendment on 1 January this year the German government introduced the new type of payment for PV installations with a capacity of up to 30 kilowatts. For every kilowatt-hour system operators use themselves they receive 25.01 cents over a period of 20 years. In addition they save the cost of their household electricity.{pagebreak}Van Hövell needs about 30,000 kilowatt-hours of electricity to light and ventilate his feeding pens and feed his 1,200 pigs in the district of Borken. Since the beginning of February he has been generating the electricity himself with his 29.4 kilowatt system. Even at today's electricity prices, van Hövell's total profit will increase by around €10,000 in 20 years because he uses his electricity himself rather than feeding it into the grid. If electricity prices rise, as is expected, he will make an even larger profit. At the moment household electricity costs approximately 20 cents per kilowatt-hour. With the extra tariff this makes a total of 45.01 cents - two

Developers from DEGERenergie have created a so-called design tool which planners and operators of solar plants can use to safeguard against storm damage - providing a standard of safety that is currently not demanded by legislators or insurance companies. Tracking systems from the company increase the energy yield of photovoltaic systems by up to 45 percent.{pagebreak}When Hurricane Kyrill swept across Europe in January 2007 it left a trail of devastation behind it. The storm reached gusts of up to 225 km/h, took 47 lives and, in Germany alone, it caused damage amounting to Euro 4.3 billion.A 2 megawatt solar plant, valued at around ten million Euros, was destroyed. Artur Deger, founder and managing director of DEGERenergie: "In future we will have to reckon with more and more storms like this. This is why it is so important to actively deal with the subject, rather than just waiting for something bad to happen. After all, there are currently new solar plants being put up everywhere."According to the company spokesman, the problem begins with the legislator: "Up to now there have been no pertinent guidelines for erecting photovoltaic plants. It has not even been decided whether such a plant is to be

KUKA innovation at the Photovoltaic Technology Show 2009Solar modules for a perfect frame (of mind)Augsburg, 17 February 2009 (pk) - KUKA Systems is presenting its new ROBO FRAME module (for which a patent application has been filed) at this year's PTS (Photovoltaic Technology Show) trade fair in Munich. Furthermore, KUKA Systems will also be displaying there its entire product range for flexibly automated production systems for solar modules.{pagebreak}ROBO FRAME uses an industrial robot with a high payload capacity for the automatic framing of solar modules. The main advantages of this production process are the prevention of deformation and scratching, improved quality of the end product, and greater throughput of the production system as a result of precision and high availability.In the ROBO FRAME system, the robot grips the prepared laminate on the glass side and guides it precisely into the prepared frame parts. In a sequence of four steps, the long frame parts are joined first, then the short frame parts into which the corner connectors have already been inserted automatically. Addi-tional clips and a level support plate ensure that the forces applied to the lami-nate during assembly of the frame parts are kept to a minimum, thereby pre-venting deformation.The

Inspired by the beauty industry, scientists have devised a way to make solar panels cheaper and more efficient - by spraying them on. Researchers from the Australian National University (ANU), solar company Spark Solar Australia, and Finnish materials company Braggone Oy are collaborating on a three-year project that could transform the production of solar cells.{pagebreak}"I think it has a big chance of success," says Keith McIntosh, lead researcher from the ANU, "It's an exciting possibility."Solar cells are typically made of silicon coated with a thin layer of silicon nitrate (which is used as an antireflective agent to increase cell efficiency). However, these types cells are costly to produce because they are made in a vacuum. Furthermore, the plasma form of hydrogen, another costly material used in solar cell production, is used to capture the energy from the sun's rays.However, the pioneering method developed by Braggone Oy uses a spray-on hydrogen film and spray-on anti-reflective film. Instead of the need for plasma and a vacuum, the cells are simply conveyed along a conveyor belt where the films are sprayed on."The cells will be the same quality, but much cheaper," McIntosh said. Testing of the process is now taking place at the
