![]() If you are thinking about investing in a domestic wind turbine, then there is more to consider than just the cost of the turbine itself. *5 A power inverter will also be required to convert the AC electricity to DC, as well as a bank of batteries. Micro domestic turbines are ideal to charge battery banks with electricity and cost around £800 (price at 2019). Some of the larger wind turbines feature artistic and architectural designs that offer an aesthetic as well as functional benefit. Standalone wind turbines cost between £9,900 and £19,000 for a 2.5kW system, while a 6kW version is likely to be between £21,000 and £30,000. However, because they are more likely to invite planning permission objections, they are not suitable for urban areas. Standalone wind turbines generate more energy than roof-mounted alternatives. Standalone wind turbines, also called free-standing wind turbines or pole-mounted wind turbines, are more effective when situated on top of a hill, away from obstructions and turbulence. However, roof-mounted wind turbines are typically small and may not generate enough electricity to meet your requirements. This type of turbine is easier to install and cheaper than other versions, costing up to £3,000 for a 1kW system. The height advantage of roof-mounted turbine systems provides the necessary wind force to generate electricity, feeding it directly to a property. ![]() There are three main types of turbine systems to cater for in the domestic market: Roof mounted *2Ī HIES installer will be able to offer you expert advice on the specific requirements of your property. Garrett acknowledges that all new technologies like vertical axis turbines face challenges, but he believes that the technology is now at a stage where the challenges of previous generations can be overcome.Domestic wind turbines can range in size from 400W to 100kW – which one will meet your requirements depends on the size of property, the amount of electricity you want it to generate and how energy efficient your home is.Ī 1.5kW wind turbine situated in an area with an average wind speed of 14mph would be sufficient to meet the needs of a home requiring 300kWh per month, for example. If a customer sells energy back to the grid, the payback time for the turbine would be around 9 years. Garrett told Springwise that a ballpark figure for the manufacture and installation of the AuraGen is around £7,000 (around €8,250). One of the benefits of the AuraGen design is its low cost of installation. Website: /programme/young-innovators/Ī key consideration for any home energy system is the cost. Springwise has also spotted a portable wind turbine weighing only 10 kilogrammes. Another designer has developed a wind turbine ‘wall’ that can be tailored to the aesthetic of each home. The AuraGen is not the only domestic wind power solution spotted by Springwise. Thanks to the AuraGen design, Garrett received recognition as a winner of this year’s UK Young Innovators Awards. He told Springwise that his experiences working in the wind stuck with him and gave him the idea for a roof-mounted wind turbine. The idea for the AuraGen came to Garrett as a teenager when he worked on scaffolding and rooftops with his dad. This latter point means that the AuraGen could potentially be used to charge electric vehicles overnight. This increases stability, meaning that the turbine itself can be wider, leading to greater power generation.Ĭompared to solar panels, wind turbines have a much higher power density and can operate at night. This is an important benefit as, by using the height of the house, the design does not require a tall support structure. ![]() In fact, the shape of the roof enhances the turbine’s performance, acting like an aerofoil to increase the velocity of air going through the turbine.Ī frame is used to directly attach the turbine to the roof. The new turbine is omni-directional, which means it works no matter which way the wind is blowing, and the technology is tailored to work most effectively on pitched roofs. Moreover, the design is simple-reducing maintenance requirements-and offers good power performance. The AuraGen’s unique design aims to minimise a phenomenon called ‘dynamic stall’ where factors such as wind shear and turbulence place a heavy load on turbine blades – reducing their lifespan. To reverse this situation, UK engineer Joe Garrett has developed the AuraGen – a new vertical axis wind turbine designed to be mounted on homes and commercial buildings. But while solar panels on domestic homes are an increasingly common sight in urban and suburban areas, far fewer houses are installed with wind turbines. ![]() Spotted: For homeowners looking to power their house with renewable energy, wind power offers a more efficient and environmentally friendly alternative to solar panels.
