Unless you’re willing to buy a Tesla Powerwall, the best rate you can get with the SEG is 7.5p per kWh if you’re with Octopus Energy.Whirlwind Wind Turbines Domestic Installations Through the SEG, you’ll be paid for each kilowatt hour (kWh) you feed back into the grid, but the rates aren’t brilliant. You can export any unused electricity that your turbine generates back to the grid via the Smart Export Guarantee (SEG). Standalone turbines normally reach up to 15 kW, which will be more than enough power for all but the very largest properties.Ĭan I make money from small wind turbines? How much electricity can a small wind turbine produce?Ī roof-mounted wind turbine will generate between 0.5–2.5 kW, which will help reduce your grid reliance but won’t be enough power to completely replace mains electricity. It’s always best to get a trusted professional to install your wind turbine, especially with standalone systems. Foundations need to be dug and filled with concrete, the turbine needs to be lifted into place with specialist machinery, and complicated wiring needs to be done properly. That’s because there is more work needed to prepare the turbine. Standalone wind turbines can take longer - three to four days is the norm. Installing a roof-mounted turbine can be done in a matter of hours by a professional. How long does it take to install a small wind turbine? This can add a further £10,000–£20,000 to the total cost. You’ll also need to pay for planning permission costs, installation, and connecting a standalone turbine to the grid. It’ll cost you up to £70,000 for a 15 kW system, which will provide roughly 36,000 kW annually. Standalone turbines cost from £7,000 for a 1.5 kW system, which will generate around 2,600 kW per year. Standalone wind turbines typically generate between 3–15 kW per day, and some of the largest models can generate more than 25 kW.Ī roof-mounted wind turbine will cost you about £2,000 for a system between 1–2 kW, but as this system won’t generate much power, it will take a while to recoup that cost. They’re also more expensive, starting at around £7,000, going up to £70,000. That makes them less than ideal for urban environments. They work most efficiently in open spaces, which means standalone wind turbines are best suited for rural properties with a lot of land. It still depends where you place them though - a free-standing turbine flanked by trees or taller buildings isn’t going to be optimal. Standalone wind turbines are more powerful than roof-mounted turbines, because they’re bigger and can take better advantage of the wind. The average UK home uses 8 kW per day, so a roof-mounted wind turbine would provide enough power to ensure you don’t always need to use electricity from the grid. You can normally generate around 1–2 kilowatts (kW) of electricity. It’s typically cheaper to install a roof-mounted turbine than a standalone one, although their size means they are less powerful. They have the advantage of height, which means they’ll get the most out of the wind blowing over your home. Roof-mounted wind turbines are installed on top of your roof, much like solar panels. You don’t already have an air source heat pump installed.The highest point of the wind turbine is no higher than 11.1m.The turbine doesn’t rise more than three metres above the height of your chimneyįor standalone residential wind turbines, you must stick to these rules:.If you have an air source heat pump, you will need planning permission for a turbine.You don’t have an air source heat pump installed.You live in a detached home, surrounded by other detached homes.Your installation meets Microgeneration Certification Scheme (MCS) standards.You can install a roof-mounted wind turbine on your home in England as long as you meet these rules: You’ll need to get planning permission in this case. Wind turbines work best when they're higher up, which doesn't present problems for rural properties far away from other homes.Ĭomplications arise when you're living in a semi-detached house, for example. You can install wind turbines on your property, but there are rules. Can you put a small wind turbine on your property?
