Wind Turbines - Frequently-asked Questions

There's a wide number of factors to consider when planning a wind turbine installation. To help you decide what will be best for your project, we've put together some frequently-asked questions. If there is anything which you are unsure about, or would like to discuss in further detail, please do not hesitate to contact us. Similarly, if you would like a firm quotation for your project, see the relevant link at the end of the page.

 

How Long does installation take?
This depends on the system you require installing and the amount of cabling and roofing work required. Generally between 1-5 days from arrival to commissioning your system by our highly-qualified and experienced engineers. 

Where can I site my system?
The siting of a wind turbine system is critical to the output which could be achieved. Ideally a wind turbine would have no obstructions between it and the prevailing wind direction. In an urban environment, some wind turbulence is inevitable unless the turbine sited well above any surrounding buildings.

Will I require planning permission?
Yes, you should liaise directly with your local planning authority to discuss the wind turbine as a planning application would normally be required. Typical reasons for rejection are: the physical appearance of the turbine, the vibrations or the noise associated with it's operation. However, levels vary depending on the model you choose, it's location and it's fixing or mounting-type. We will assist you with any planning issues you may have, howver we will be unable to converse with the planning authority directly on your behalf.

Why install a Wind Turbine?
By installing a wind turbine on your property, you can generate 100% ‘green’ electricity which not only reduces your electricity bills but also offsets carbon dioxide emissions. Wind Turbines, large and small play an increasingly large role in sustainable development, with many housebuilders installing the technology. Key advantages of Wind are:
  • Zero emissions
  • Operational 24-hours
  • Greater visual impact
  • Minimal visual intrusion – infact integrated Solar tiles often look like regular tiles

How much power will a wind turbine system generate? 
Turbines are rated in kW peak (kWp). It is important to realise that this is the power produced under standard temperature and light conditions and so a generator rated at 1 kWp will often be operating at well below this capacity in the UK climate. kWp is a unit of power and a measure of the system’s performance at a particular instance. A more useful parameter is the amount of energy (kWh) generated over the course of a year.

How long will my system last?
The average lifetime of a wind turbine can be in excess of 20 years. Different manufacturers of wind turbines have different warranty periods, and we’ll be happy to advise you on warranty terms. We also guarantee each installation for a period of 2 years. This is a fully comprehensive warranty which covers our installation, labour and equipment. Other parts of the system, such as inverter, display units etc all have manufacturers standard warranty attached, again we will be happy to advise you on this.

What about maintenance?
All Wind Turbine systems require servicing and an inspection annually. We will be happy to provide costs and packages.

 

I’ve heard that I can sell my energy back to my power company.
There's an increasing number of companies which offer domestic customers the ability to earn revenue from their electricity generation. Click here to learn more.

 

Is there any assistance available in the form of grants?
The Department for Trade and Industry (DTi) can help with funding for your system under the Low Carbon Buildings Programme. This provides upto 50% of your installation costs or £2,500 whichever is lower.AAG Swepco is accredited by the DTi which means we are authorised to install systems under their grant scheme. In order to obtain a grant, you must submit details of your project and a quotation from us. We will provide all the necessary information for your application and a decision typically takes 7 working days. Once the installation is complete, the DTi will refund the grant amount to you directly.You must undertake a number of energy efficiency measures before you are eligible to apply for a Low Carbon Buildings Grant. These measures will ensure that you are minimising your energy requirements. Before applying we require you to have:  

  • insulated the whole of the loft of the property to meet current building regulations e.g. 270mm of mineral wool loft insulation or suitable alternative
  • installed cavity wall insulation (if you have cavity walls)
  • fitted low energy light bulbs in all appropriate light fittings
  • installed basic controls for your heating system to include a room thermostat and a programmer or timer.

We recommend that you complete a home energy check to assess which measures are most suitable for your home. You can also call your local Energy Saving Trust advice centre on 0800 512 012 for guidance on energy efficiency measures and energy efficiency grants available in your area.

 

How much can I get in the form of a grant?
Homeowners in England and Wales can obtain £2,000 per kW of installed capacity, upto a maximum of £2,500 or 50% of the total cost, which ever is lower. Different grant schemes operate in Scotland too. Please check our funding guide section (here).
