Frequently asked questions

Buying Considerations
  • Why are your wind turbines white with blue?

    All Kestrel's turbines are manufactured to the latest IEC International Wind Turbine standards. Turbines which are designed under these standards will be low impact and follow the guidelines on colour and aesthetics (colour is white non-reflective). The blue is just the non-invasive Kestrel touch. Wind turbines should be silent if used in domestic situations and our silent ones have no noise and can be placed outside your bedroom window if required.

Energy Usage
  • How is energy used in my home?

    Breakdown of energy usage in your home is as follows:

    • Heating and cooling - 51%
    • Pool pump - 13%
    • Water heating - 12%
    • Refrigerator - 5%
    • Electric Dryer - 4%
    • Other - 15%
Environmental, Legal and Safety Concerns

Generating Power
  • What are the benefits of small wind?

    Environment. Wind energy is non-polluting, and reduces the demand for higher-impact electricity from thermal stations (e.g. oil, natural gas, coal), hydroelectric dams and nuclear generators. Energy Independence. Wind turbine systems can assist you in gaining more independence from your local utility. They can also make you less susceptible to power interruptions from the grid. Cost. Wind energy systems are one of the most cost-effective home-based renewable energy systems. Depending on your wind resource, a small wind energy system can lower your electricity bill by up to 100%. They can also help you avoid rising and volatile electricity prices. Remote Electricity Generation. If you are at a distance from existing grid lines, generating your own electricity helps you avoid the high costs of having utility power line extensions. Complements Solar PV. Solar photovoltaic (PV) systems generate more electricity when there are more hours of sunshine and higher intensity sunshine (i.e. during the summer). Wind turbines generate more electricity when there are more hours of wind per day and higher intensity winds (i.e. during the winter). This makes wind an excellent complement to solar PV in a renewable electricity system.

Global Warming
  • Could I power my household using exclusively solar and wind power?

    Yes, it is possible to do so, but connecting to the grid is cheaper. Indeed, these renewable sources have the inconvenience to be intermittent: sun only shines at daytime, and wind isn't continually blowing. So costly batteries are needed to stock energy for the times when the household does not produce it. This can be avoided by using the grid as a 'backup'. Ultimately, connecting to the grid enables to feed in to it, providing a steady income.

  • How strong does the wind have to blow for the wind turbine to work?

    Cut-in speeds start at 2m/s and do not exceed 2.8m/s

Water Pumping
  • Is a renewable energy system suitable for my home?

    Different off-grid and grid connected systems have been installed at homes across the globe. A few things to consider when installing a renewable energy system at your home: Your location is very important when you are considering installing a renewable energy system. There must be no significant nearby obstructions like trees or buildings on your property as these are likely to reduce wind speed and increase turbulence. System installation normally requires permission from the local authority, so it's important to always check with your local authority about planning issues before you have a system installed. An EIA (Environmental Impact Assessment) is needed when installing a turbine of 15 metres or higher.

Wind Turbine Installation
  • Can I put a turbine in my garden or on the roof of my house?

    Kestrel's turbines can be roof mounted on high-rise buildings with flat roofs such as university/school buildings, office blocks and tower blocks as well as a standard domestic house with special reinforcements to limit vibration damage to your roof and your turbine. This is because of the loads that the building would have to take and a normal domestic household need this special reinforcement to bear these loads.
