Munich, January 2009 - Yamaichi Electronics presents the new product series Y-Sol® for the complete wiring of PV systems for the first time at the intersolar 2008 trade show in Munich. PV module junction boxes for silicon and thin film modules as well as connector and cables ensure reliable operation of the systems for their entire life as well as their highest possible efficiency level. All products are developed and manufactured in Germany.{pagebreak}Junction boxes with IP65 protection class are available for both module technologies - silicon modules (monocrystalline and polycrystalline) as well as thin film modules. Junction boxes are installed on the back of the PV modules. They have to primarily conduct the direct current generated by the module to the outside via contact terminals. The junction box comprises, with silicon wafer based modules, one or more voltage-controlled bypass diodes depending on the application. There is one bypass diode at most in the junction box for thin film modules. If one module fails due to shadowing or soiling, for instance, the bypass diodes will ensure that the current is conducted around the affected cell areas.One feature of the Yamaichi junction box, also called J-Box, is the use of SMD diodes

* DIS AG welcomes federal cabinet's decision regarding Posting of Workers Act (German 'Entsendegesetz')* This will effectively prevent wage and social 'dumping'* Quick implementation of legal process is required{pagebreak}Düsseldorf, July 17, 2008 - DIS AG, the market leader in hiring and placement of skilled personnel and managers, welcomes the compromise regarding the Posting of Workers Act adopted by the federal cabinet after months of disagreement between CDU and SPD. "The amendment to the Act, which was decided by the federal cabinet, provides the basis on which additional industries will be able to introduce minimum wages", says Andreas Dinges, Chairman of the Board of DIS AG. "On the basis of this decision, the principle of temporary employment will doubtlessly be added into the Posting of Workers Act without any problem."Temporary employment is one of the industries with a minimum of 50 percent wage bargaining coverage, where the parties to a collective wage agreement have filed a petition to include these industries into the Posting of Workers Act. This inclusion was however not the subject of the cabinet's decision. A decision on the subject will later be made by a coalition work group, under the leadership of the federal employment minister Olaf

Biel, 12 December 2008. On 28 November the Spanish company Vasolar 2006 S.L. and its Portuguese business partner Cavalum SGPS, S.A. inaugurated four solar parks delivering a total output of eight megawatts in the autonomous region of Extremadura. The tracking systems produce on average 26 gigawatt-hours of energy per year, covering the requirements of about 8,300 households and saving 25,000 tonnes of carbon dioxide. {pagebreak}250 people came to the inauguration, including the mayors of the villages of Fuente de Cantos, La Albuera, Don Alvaro and Montemolín, where the solar installations produce their electricity.For the tracking systems, operators Valsolar and Cavalum still receive the higher feed-in tariff guaranteed by royal decree RD 661/2007 for solar installations commissioned before the end of September. The decree guarantees a higher payment for installations of up to100 kilowatts. Valsolar and Cavalum have therefore divided the four solar parks into smaller systems, each with an output of 100 kilowatts. They receive 45.51 eurocents for each kilowatt-hour fed into the grid. The four solar parks cost a total of 40 million euros. Valsolar is reckoning on a payback period of 10 years.When deciding on which inverters to install, Valsolar and Cavalum chose Sputnik Engineering's 100-kilowatt central inverters.
