Example: Average Wind Speed 5.5m/s = estimated 1100kwh = 1100kwh of electricity over 12 months or more if the wind speed is higher. At 6.5m/s this would increase to an estimated 1800kwh and at 7.5m/s an estimated 2,500kwh increasing exponentially.

Small domestic wind turbines are a way for UK homeowners to produce free, green electricity using wind power. Yet, according to MCS data, only 125 have been installed across the UK. Standalone wind turbines are better value for money than roof-mounted ones because even though they are more expensive, they produce much more electricity. Permanent magnet generator of 40 poles, 20 kW maximum power at 120 rpm and 1,700 Nm provides a high level of energy performance. In the UK, the average household uses around 2,900 kWh of electricity each year, therefore, if you want to generate enough power to fulfil this amount, you would need a wind turbine that can generate around 241 kWh a month. Shut-down speedis another matter. Some wind turbines ‘flat line’ their output at their rated output until the wind reaches its ‘survival’ speed. A 10kW wind turbine with a survival wind speed of 30m/s will continue to produce 10kW as the wind speed increases from 12m/s to 30m/s before shutting down. The maximum output of that 10kW turbine may be a bit more than 10kW, up to 12kW.Overall, the Bergey BWC EXCEL 10 is the best 10kW small home wind turbine on the market. Its high power output, lightweight design, and affordable price tag make it a top choice for homeowners or businesses looking to save money on their energy bills.

It’s important to bear in mind that wind turbines need to be as high up as possible, to enable them to capture an adequate amount of wind to generate power. The nacelle (the working part of the equipment) is at the top of the mast, and this needs to be taken down to ground level to be maintained or repaired, which will be expensive.

Making a roof-mounted wind turbine with cheaper price (due to lower size and no tower) wouldnt be a problem for our company. Neither would be selling it to a large number of customers due to low price, easier installation and a larger customer base. There is a reason why we refuse to make profit on this and this reason is that roof-mounted small wind turbines are simply not good!

Wind turbines have a warranty period, typically 10-20 years. Make sure you read the small print: some manufacturers might cover parts only. This means that the owner pays for labour and for dropping the nacelle, and can only use parts supplied by the manufacturer. This effectively makes the warranty valueless. Conclusion: Are Wind Turbines Worth it? If you want to know if a home wind turbine could work for you, the first thing to consider is how much space you have. Remember, your wind turbine will capture more energy the higher it’s placed, and the bigger its blades. One other thing that you will need to take into account before installing a wind turbine on your premises is the effect that it may have on the property price. There is not much evidence currently available that having one installed with have a large adverse effect but a lot may depend on how efficient your system is. Of course, it will also depend on your location. If your wind turbine is on farmland and producing a good return on the Feed in Tariff it is more likely to add value to any sale. If you have a roof mounted system that simply takes the edge off your energy bills, you might find that aesthetic principles come into play.

The Energy Saving Trust recommends installing one of these devices in the place where you plan to put your wind turbine, and leaving it there for a couple of months. This will give you the best, most precise data, to help you decide whether a domestic wind turbine would be worth it for you. You could do this yourself, or hire a professional to investigate for you. Find out more from the Energy Saving Trust. Do you need to get planning permission for a home wind turbine? Wind turbines are low-carbon: they’re a green, renewable source of energy, and don’t release any carbon emissions, which fuel the climate crisis.

If you believe you have sufficient amount of space for a wind turbine, there are some other important considerations… What is Your Wind Speed? turbine. The international standard defines it by the rotor swept area, but the more common definition is by the power rating (kW). Over the course of a year, a turbine will generate about 30% of the theoretical maximum output, which is known as the capacity factor.
