Performance Proves Even Greater in Latest Tests of Endurance E4660 Wind Turbine
Early testing of the E4660showed a 35% improvement in energy production, a main point of communication at the new design’s launch in the Autumn. Following that initial testing, further good news came in official reports that confirmed extremely low acoustic levels.
Perhaps the quietest machine available, this new performance data showing a nearly 40% boost in production, makes the E4660 an even further advancement of technology, engineering and design.
“We were very excited when this second set of official test data came back,” said Brett Pingree, Vice President Commercial, speaking from Endurance Wind Power’s West Midlands office. He added, “The early test data that showed 35% more energy made a really strong financial case for investors in this machine, but now at nearly 40%, well that’s great news for everyone, isn’t it?”
The new E4660is a powerful advancement of the UK’s leading machine, the E3120. Built from the same engineering platform, the new E4660incorporates design and technology advances developed from more than fifteen million hours of E3120 performance data. Yet the exterior size and shape are virtually the same as the E3120, which is among the most successful wind turbines in planning applications.
“It’s a more robust machine, with a larger rotor, that produces significantly more energy. The result is that the E4660 produces about 39% more energy than its forerunner at a 6 m/s average. Despite this, it is a very quiet design. For farmers trying to diversify their income, the E4660is a great choice even with a modest wind resource.” said Ed Mufford, Vice President of Engineering at Endurance.
Brett Pingree agreed and added, “The energy production of this powerhouse makes small wind lucrative again, in more places across the UK. People are taking another look at what wind can do for them.”
Endurance, which operates a large manufacturing facility in the West Midlands, reports very strong sales for the E4660in its first months of production.
