- E4660 produces 39% more energy at 6 m/s than the leading E3120 
- Latest test data adds 4% increase above original testing

- Larger rotor makes wind work in more places
London – Newly released performance data for the Endurance E4660 shows a 39% output improvement over the UK’s best-selling small wind turbine, the Endurance E3120.
Early testing of the E4660 showed 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 E4660 is a powerful advancement of the UK’s leading machine, the E3120. Built from the same engineering platform, the new E4660 incorporates 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 E4660 is 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 E4660 in its first months of production.
 39% more production when comparing Annual Energy Production to engineering estimates for all wind speeds of 6 metres per second and 38% more production for all wind speeds below 5.5 m/s and over 7 m/s
