The Endurance E-3120 is a 55kW downwind machine with a 30 year design life and 5 year warranty. It can out perform other wind turbines rated at 80kW.
The Endurance E-3120 Wind Turbine is designed for farms, irrigation pivots, schools, hospitals, manufacturing and fabrication companies, and any other applications requiring 125,000 to 250,000 kWh per year of electricity. Spinning at a low rotor speed, the 19.2m rotor diameter is designed specifically for higher efficiency in wind speed conditions usually experienced in the UK.
Wind power provides electricity for individual or multiple buildings with any 'excess' power being sold back to the National Grid. On Farms, because wind turbines take up little space, renewable energy is produced without compromising valuable farmland.
