Choosing a wind turbine and finding an installer

 

Choosing a turbine  

To be eligible for payments through the Feed in Tariff, your wind turbine must be certified under the Microgeneration Certification Scheme (MCS) and the turbine must be installed by an MCS-certified installer.

MCS-certified wind turbines below 15kW

This information has been extracted from the manufacturers’ websites and technical data sheets during April 2012. Please note that we are not responsible for the accuracy of the data presented.

For the latest list of certified turbines, and turbines 15kW and over (to 50kW) if you have a suitable site for a larger turbine, check the MCS wind turbine product database.

Power ratings

You will notice that the rated power (in kW) of different wind turbines is given at different windspeeds measured in meters per second (m/s). This makes it  difficult to make a side by side comparison of the likely output of one wind turbine compared with another even if both state that their rated power is, for example, 5kW. To overcome this problem RenewableUK introduced the Small Wind Turbine Performance and Safety Standard. As part of the MCS approval process the approved wind turbine has to be measured against this standard. This will result in additional information being available in the form of a summary report which will help you assess the likely performance of one turbine against another.

In general terms the information includes:

  • the BWEA Reference Power, which is the rated power of the wind at 11m/s
  • the BWEA Reference Annual Energy, which is the amount of energy in kWh that the turbine will produce in a year at a constant windspeed of 5m/s at a stipulated hub height
  • the BWEA Reference Sound Levels at 25 and 60m rounded up to the nearest decibel (dB) from the turbine.

A turbine which meets the requirements of the BWEA small wind turbine standard will have a label (which should be used on all product literature and advertising) which looks like this:

BWEA Small Wind Turbine Performance and Safety Standard Label, Feb 2008

Evidence of compliance with the Standard is required before small wind turbines (up to 50kW) can be certified through MCS, as set out in MCS006.

 

Finding an installer  

There are no national grants available to householders to help cover the cost of installing a small wind turbine.

We strongly recommend that you choose a system and installer that are certified by the Microgeneration Certification Scheme (MCS); this will help you to ensure the quality of your installation and the level of customer care that you receive. To be eligible for payments through the Feed in Tariff, your turbine must be installed by an MCS-certified installer.

Search for products and installers at the MCS website.

 

Before you start...

If you're thinking about installing a system to generate your own heat, make sure your home is as well insulated as it can be so your heat-producing system can be most efficient.

Focus on improving insulation and tackling draughts.
