The turbine will have the necessary controls to ensure that the blades turn no faster and the generator is asked to do no more than 12kW. The maximum output of that 10kW turbine may be a bit more than 10kW, up to 12kW. 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. Some wind turbines вЂflat lineвЂ™ their output at their rated output until the wind reaches its вЂsurvivalвЂ™ speed. Start-up speedВ is the speed needed to start generating and is a key factor to production. More important are the start-up and shut-down wind speeds: This reflect its optimum wind speed, in this case, usually something between 10m/s to 12m/s, which is a fairly strong wind.

The rated outputВ of a wind turbine is what the turbine is called, for example, a 10kW turbine. Value of production:В All used on site, no FiTs ВЈ570ДЄssume a south-facing roof and a capacity of 3.9kW: Wind or PV?ДЄssume a wind speed of 6.5m/s and a capacity of 2kW: However, a 1kW-2kW machine that is not grid connected will do all that a normal household needs. There is an argument that turbines need to be 5kW or more to justify the investment. This needs to be checked with the grid operator before any other plans are made. Even when it can be connected, upgrading a grid connection can cost thousands or tens of thousands of pounds.Д¬onnection, with no upgrade, is usually possible for generators with a capacity below 4kW. In these areas it may not be possible to connect the turbine to the grid. The UK electricity grid is nearing maximum capacity and in some areas, like the south coast of England, it is already at capacity. To avoid it, the turbine needs to be positioned so that it is not directly between the sunвЂ™s path and any neighbouring properties. It is caused by the blades passing in front of the sun and making the sunlight appear to flicker to anyone вЂdownstreamвЂ™ of it. Wind turbines are not silent, but as there must be some distance between the turbines and any houses, there is little perceivable noise.ДЇlicker can be a real nuisance and can affect people with epilepsy. Potential noise is the usual objection, with little cause. ecological and bat surveys (opens in new tab).The process can be expensive and time-consuming, covering: They will almost always attract objections, usually from neighbours.

This gives the electricity a value of 15p/kWh as it displaces electricity bought from the grid. will produce around 2,000 kWh with a 6m/s wind speedДЄs this is not grid connected there is no Feed-in Tariff and all the production must be used on site.costs around ВЈ1,200, with total installed costs of ВЈ2,000.attract a Feed-in Tari (opens in new tab) f (opens in new tab) f (opens in new tab)В of 8.26p/kWh and export tariff of 4.8p/kWh - a return of ВЈ1,310 per yearДЄnother option might be a tiny turbine, like the FuturEnergy Airforce1 1kW machine.produce around 10,000kWh per year with an average wind speed of 6m/s, almost enough for two average households.Add to that the cost of preparing the site, erecting the turbine, laying cables to the grid connection and planning consent, and the final cost could reach ВЈ30,000-ВЈ40,000.ДЄ good 5kW wind turbine, such as the Britwind R9000, will: A 5kW wind turbine would be usual for a domestic installation and will cost around ВЈ20,000-ВЈ25,000.

Strong wind that is disrupted by trees or tall buildings will not do. Useful wind is affected by topography and obstructions, as well as speed.
