Vestas surprises with 7 MW offshore wind turbine

Danish wind turbine maker Vestas unveiled a new giant 7-megawatt offshore turbine on Wednesday and said it expected it to be in serial production in early 2015. Vestas, the world's biggest wind turbine manufacturer by market share, had only been expected to unveil a 6 MW turbine, not the towering 135-meter (443 feet) 7 MW unit, with its rotor diameter of 164 meters. The new turbine, whose rotor will trace a circle bigger than the London Eye ferris wheel and whose 80-meter blade is longer than nine London double-decker buses, is part of a push toward larger and larger units further offshore, where the wind power potential is high and public resistance can be avoided. Chief Executive Ditlev Engel told a news conference in London that the new turbine, designed for North Sea conditions, was the first that Vestas has developed specifically for offshore wind parks and its single largest research and development ever. Wind currently accounts for just 2 percent of the global energy mix, but Vestas expects it to provide 10 percent in 2020, Engel said in a presentation. Most of the growth in offshore wind power capacity to 2025 will be in Europe, he said. President of Vestas Offshore, Anders Soe-Jensen, told the news conference the company expected the offshore wind market to grow by 8.4 percent annually from 2015 to 2025.

Darfon G320 Microinverter

The Darfon G320 is the microinverter solution for today's high-power solar modules. The G320 handles 60- and 72-cell modules up to 350W DC and outputs up to 300W AC. The G320's 3-phase configuration accommodates the electrical distribution systems of most commercial buildings and to reduce, if not eliminate, the need for expensive transformers. The G320 comes in four voltage/phase configurations, so it can be installed in residential, commercial or utility applications.
