Proven WT600 600w
The 600W Proven wind turbine is the smallest wind turbine we manufacture. Standing at the same height as a telegraph pole this miniature can provide enough electricity to power lighting
circuits in a standard 3-bed house in the UK. More commonly however, the 600W is used by telecoms companies to feed power into batteries for
telecoms repeater/booster stations and has been used by the MOD (Ministry of Defence), BT,
Orange and T-Mobile.

Proven WT2500 2.5kw
The 2.5kW Proven wind turbine is the ideal wind turbine for powering a standard 3-bed house in the UK. The output almost matches typical demand of such a house (electrical appliances only, not electric heating) and can provide a little power for exporting in some cases. Several hundred of these turbines and its predecessor have been successfully installed world- wide. Surviving everything from hurricanes and cyclones to freezing cold temperatures in the Arctic and scalding heat in the desert. This all-rounder is also aesthetically pleasing from a planning perspective due to its height being similar to that of a 600-watt telegraph pole and overall physical scale being in tune with a domestic dwelling.
WT 2500Rated Output: - 2500W (2.5kW)
Voltages available: - 12V / 24V / 48V / 120V / 240V / 300V
Annual Output - 2,500-5,000 kWh*
Rotor Diameter: - 3.5m
Hub Height: - 6.5m / 11m
Prices start from £11,700 excluding VAT and ground works (Ground works can be carried out by a local builder or we can arrange this for you).

Proven WT6000 6kw
WT 6000A 6kW turbine will give about 3 times more power than a 2.5kW wind turbine and therefore is better suited to a larger house or to someone who wants to generate an excess of electricity for exporting on to the national grid. This turbine is an extrapolation of the technology used to design and build the 2.5kW wind turbine and is therefore just as reliable and robust.
Rated Output: - 6000W (6kW)
Voltages available: - 48V / 120V / 240V / 300V
Annual Output - 6,000-12,000 kWh*
Rotor Diameter: - 5.5m
Hub Height: - 9m / 15m
Prices start from £17,580 excluding VAT and ground works (Ground works can be carried out by a local builder or we can arrange this for you).
