Proven WT2500 Wind Turbine
Find out more about the Provenenergy WT2500 2.5kW Wind Turbine
Proven produce a range of mast mounted rugged wind turbine generators. Starting with the smallest (WT600 600 Watt) wind turbine, up to the largest (WT15000 15kW) wind turbine, the Proven range offers something for all requirements whether powering just a domestic light circuit or an small estate of homes. Here we will discuss the Proven WT2500 as it is the wind turbine generator best suited to typical domestic use as it is just about able to power the electical appliances in a standard 3-bed house without being too loud, large, or expensive. (pictured above is the 6kW model which can power a large house, but is not so suited asthetically for domestic use.)
With a 3.5 metre diameter rotor, the WT2500 wind turbine is available in 24, 48, 120, 240, and 300 Volt versions and can generate between 2,500 and 5,000 kWh of power per year with average wind speeds of 5m/s on an ideal site. Proven wind turbines are downwind (1) turbines.
Although the Proven wind turbines are more expensive than the vast majority of generators on the market, you are paying for reliability and durability. All turbines are marine quality built from galvanised steel, stainless steel, and plastics. The three blades are made from polypropylene, and the generator is a brushless, direct drive, Permanent Magnet Generator (2). 24V or 48V DC models can be used for battery charging, or the higher voltage AC models can be grid connected with a windy boy inverter to the grid, or to direct heating. The mast is self supporting therefore no guy ropes to trip over or wasted land, and the mast is of the tilt-up variety.
The generator and blades weigh in at almost 200kg and the tower is 241kg (6.5m) or 445kg (11m). Noise generation is not bad at 60 decibels in winds of 20m/s, and this proven wind turbine has no cut-out wind speed and a difficult to match survival wind speed of over 60 m/s.
The standard tower is 6.5 metres, however an additional £1400 will get you an upgraded 11 metre tower getting your wind turbine up into cleaner air and generating more power more often. A grid connected system will cost around £11,000 compared to a battery charging system at almost £16,000. If the turbine is to be used for heating only then the costs drop to just under £10,000. All prices exclude VAT. As always grants are available to reduce the total cost by up to £5,000.
