Cost Ranges

In general prices are in the range of £1,500 - £3,000 per kW installed - we can provide up to date costs and information on any bulk discounts that may be applicable.

Systems up to 1kW will cost around £1500 whereas larger systems in the region of 2.5kW to 6kW would cost between £10,000 - £25,000 installed. These costs are inclusive of the turbine, mast, inverters, battery storage (if required) and installation, however it's important to remember that costs always vary depending on location and the size and type of system.

In addition to this it is possible to sell any additional electricity generated back to suppliers. Currently, costs for exporting are 9p/kWh and importing is 10p/kWh.

Output Ranges

Wind power is proportional to the cube of the wind's speed, so relatively minor increases in speed result in large changes in potential output. Individual turbines vary in size and power output from a few hundred watts to two or three megawatts (as a guide, a typical domestic system would be 2.5 - 6 kilowatts, depending on the location and size of the home).

The main factor affecting the output of wind turbines is the average wind speed. This varies for different areas of the UK but increases with the height of the turbine above ground level. Local topography can significantly impact upon local wind speeds. A small difference in wind speed will make a large difference to output.

Maintenance

Turbines can have a life of up to 20 years but require service checks every few years to ensure they work efficiently. For battery storage systems, typical battery life is around 6-10 years, depending on the type, so batteries may have to be replaced at some point in the system's life.
