  • Solarcentury Installs a 5 Megawatts Solar Park in Great Britain Using Solarmax Inverters
    Press release Solarcentury installs a 5 megawatts solar park in Great Britain using SolarMax inverters One of the largest solar parks in Great Britain has sprung up on Mingay Farm in Cambridgeshire. The British company Solarcentury installed the 14 hectare park with an output of five megawatts. Biel, 16.08.2011 : In the County of Cambridgeshire solar radiation is good, comparable with that in the south of Germany. The 19,960 solar modules installed in the Mingay Farm project generate enough energy to supply up to 1,200 homes and the solar power station will save 55,000 tons of carbon dioxide in 25 years. Solarcentury designed the system using 14 SolarMax 330TS-SV devices for the inverters. They feed their power directly from the SolarMax power station into the local energy supplier's medium voltage network. The inverters are particularly long-lasting and reliable thanks to the use of film capacitors and the intelligent monitoring of power semiconductors. With a maximum efficiency of 98 percent they also work very productively, which is confirmed by Jan Muller, Head of Technology at Solarcentury: "The SolarMax inverters have proved to be exceptionally efficient and powerful", says Muller. "What we also really appreciate is the technical support and advice by Sputnik that we can always rely on during the development and implementation of our projects." That is why Solarcentury is also trusting in Swiss quality products from Sputnik Engineering AG for its follow-up projects. The British company does not just want to use more SolarMax inverters in Great Britain but also in Italy, France and Spain.

  • Commercial News Lyss, 4 May 2011
    Commercial News Lyss, 4 May 2011 3S Photovoltaics supplies solar modules for Umwelt Arena roof What is to date Switzerland's largest building-integrated photovoltaic installation incorporates the trend-setting integrated MegaSlate® roof system from 3S Photovoltaics, a member of Meyer Burger Technology Ltd [Ticker: MBTN]. Installation is the responsibility of BE Netz, while Sputnik, based in Biel, is the inverter supplier. The three companies involved are also providing their expertise about architectural photovoltaics in the exhibition area of Umwelt Arena, Switzerland's first centre of excellence for the environment, which is being built in Spreitenbach near Zurich. As of spring 2012, Umwelt Arena's roof, which has an area of 5,300 m², will generate approx. 540'000 kWh of solar power per year, roughly corresponding to the annual consumption of 120 households. This power will be generated by 5,239 solar laminates produced by 3S Swiss Solar Systems and installed on a total of 33 differently oriented trapezoidal "facets" of the roof. Joint project by Swiss companies BE Netz, based in Lucerne, is responsible for installing the system, while a third well-known Swiss company, Sputnik Engineering, is supplying the inverters for this installation which is to date the only one of its kind in Switzerland. 3S Swiss Solar Systems, which distributes its building-integrated solar systems under the 3S Photovoltaics brand, has already carried out numerous successful joint solar projects with BE Netz. The MegaSlate® solar roof system is fitted as standard with SolarMax inverters from Biel-based Sputnik. Unique architecture combined with environmental technology As Swiss pioneers in the practical implementation of solar energy supply, these three companies are delighted to be working together on this major project.

  • Sputnik Engineering Presents Maxtalk 2 and Enhances the Flexibility of Its Solarmax-MT Inverter
    Press release Sputnik Engineering presents MaxTalk 2 and enhances the flexibility of its SolarMax-MT inverter New products at the 26th Photovoltaic Symposium in Bad Staffelstein Biel, 24-02-2011. At the 26th Symposium on Photovoltaic Solar Energy in Bad Staffelstein from 2 to 4 March Sputnik Engineering is presenting its new communications software MaxTalk 2. This tool monitors and manages the measured values of any number of solar power plants fitted with SolarMax inverters. Users can query the present status of their solar power plant, the operating data, statistics, measured values and device parameters. In comparison to the previous version (MaxTalk), the user guidance of MaxTalk 2 has been greatly enhanced. The new professional version MaxTalk 2 pro also permits registered installers additional configuration options to meet the requirements contained in the medium-voltage guideline of Germany's Federal Association of Energy Suppliers and Water Utilities applicable to solar plants in Germany from April 2011. More flexibility for plant layouts Sputnik Engineering has increased the flexibility of SolarMax MT string inverters, introduced in 2010, (rated output: 10, 13 and 15 kW) , to allow for greater flexibility during plant layout. Instead of six kilowatts of generator output per MPP tracker, it is now possible to connect a maximum of nine kilowatts of generator output. This will give installers the freedom, as when wiring the 15-kilowatt inverter SolarMax 15 MT, to connect either two module strings each with nine kilowatts DC output to the inverter or, alternatively, to select a symmetrical division of three times six kilowatts. In between these two, any combination is possible, as long as the voltage and current limits stated in the data sheet are observed.

  • Solarmax 330TS-SV Receives BDEW Unit Certificate
    Press release SolarMax 330TS-SV receives BDEW unit certificate Most powerful central inverter of Sputnik Engineering meets the criteria of the BDEW Medium-Voltage Directive. Biel, 18 August 2011 : Newly commissioned grid-coupled inverters equipped with a direct medium- voltage connection in Germany must demonstrate their compliance with the directive “Generator plants on the medium-voltage network” by means of a unit certificate of the BDEW (German Association of Energy and Water Industries). The SolarMax central inverter 330TS-SV has now received this certificate. Evaluation and certification were implemented via the accredited Fraunhofer Institute for Solar Energy Systems and the certification institute Bureau Veritas. For example, the BDEW directive requests that photovoltaic inverters must no longer shut down in the event of a short-term failure of the mains network, but must support the mains network in a dynamic manner. Furthermore, photovoltaic systems must also provide a contribution in the field of static voltage maintenance in the future by delivering and receiving reactive power in order to be able to compensate for voltage fluctuations within the mains network. The fact that the SolarMax 330TS-SV has these capabilities is confirmed by the unit certificate. “The field of photovoltaics has developed from being a hobby of individuals to become a cornerstone of the German energy supply. Therefore, it is logical that it must also provide a contribution to the system services of the electricity grid. The Medium-Voltage Directive ensures that the development in the field of photovoltaics can be continued in the future as well,” says Hans-Thomas Fritzsche, General Manager of the German subsidiary of Sputnik Engineering in Neuhausen, Germany.

  • Optimise Costs, Increase Revenues Markets Are Different
    PHOTOVOLTAICS CENTRAL INVERTERS Optimise costs, increase revenues Markets are different But the markets are subject to different conditions, according to Casini: investors and operators in Asia accept shorter maintenance cycles with increasing personnel requirements if the initial cost is low. In Europe and North America, the situation is exactly the opposite, because here the labour costs are higher. “In order to offer the right solutions for each market, Power-One will continue to diversify its product port- folio and include central inverters for both mature and emerging markets,” says Casini. Schweikardt of Sputnik is thinking more of the German market when he says that an investment in PV has to be profitable despite reduced funding, and that it is therefore important that an investor can get the greatest possible amount of energy at the lowest possible cost. For this reason, it is not only Sputnik that is trying to accommodate more powerful central inverters in a station solution, thereby reducing the number of stations needed as well as the acquisition cost. “In addition, we think it is very important,” Schweikardt continues, “that our products can be in- stalled quickly and easily to keep time and material Photo: REFUsol costs as low as possible.” More capacity in the same space – with this strategy, News from the manufacturers manufacturers of central inverters intend to help reduce However, many manufacturers are not just working the investment costs of PV power plants.

  • Press Release 2-Megawatt Solar Power Plant Installed in Bulgaria
    Press release 2-Megawatt solar power plant installed in Bulgaria with inverters made by Sputnik Engineering Biel, 28.09.2010. Today, the Bulgarian company Sunservice Ltd. is commissioning its first photovoltaic power plant fitted with SolarMax inverters in the western Bulgarian town of Ihtiman. The system delivers an output of 2 megawatts. Beside amorphous silicon modules the Sofia based company has also installed six central inverters of the type SolarMax 330C- SV. The devices each have a rated output of 330 kilowatts and achieve a maximum efficiency of 98 percent. When selecting the inverters, the head of Sunservice, Rumen Christov, attached great importance to high quality and know-how. "Sputnik has a lot of experience with central inverters," says Christov. He expects the solar plant to produce 1,250 kilowatt hours per kilowatt annually. Based on the present Bulgarian infeed rate for power, the plant operator will be paid 37.2 euro cents for every kilowatt hour produced. Because of the good irradiation conditions and the attractive price, Christov expects rapid growth in the Bulgarian solar market. "At present, in Bulgaria, less than 10 megawatts of photovoltaic capacity is installed,“ says Christov. "This year, new plants with an overall capacity of 10 to 50 megawatts will be built. By 2015, in Bulgaria, plants will be producing a total output of 500 to 1,000 megawatts of solar power. By 2020 this figure will rise to 2.5 to 4 gigawatts.“ Sputnik's head of sales and marketing, Daniel Freudiger, is looking forward to more projects in this Balkan country: “Bulgaria is a very important growth market for us.
