![]() ![]() ![]() This means that you will make a net profit of £(0.34 - 0.21)/kWh * 26280kWh = £3,416 in 10 years of operation. The floor unit prices vary by region and payment type but for electricity average at 34p/kWh for direct debit customers in Great Britain with typical energy consumption. If you buy and mount our wind power system with 7.6kWh battery on the roof at the price £5,405.00 then the wind electricity cost is £5,405.00 / 26280 = £0.21/kWh. This gives 7.2kWh per day or 7.2 * 365 * 10 = 26280kWh per 10 years of operation. If accept that your home is located in a place with an average wind speed 6.2 m/sec, then the turbine's power estimation is 300W. In general, any site with as little as 6.2 m/s (12 knots or 13.7 mph) can be viable when using our 9-blade wind turbines. To assess if your home's location is windy enough, look at the map below Below is the manufacturer's wind turbine curve for our Raptor G4 9-blade wind turbine which we offer in our wind power and hybrid wind & solar power systems The power curve is a graph that indicates how large the electrical power output will be for the turbine at different wind speeds. As an appropriate approach for the estimation of the annual power production of a wind turbine, so called "wind turbine curve" is used. Lower your electricity bills and make a profit (see an example below)Īn estimation of electric power production from a wind turbine is necessary for financial planning of the wind system.Help uninterruptible power supplies ride through extended utility outages.Help you avoid the high costs of having utility power lines extended to a remote location.If there is enough wind in your area, small wind power systems are some of the most cost-effective home-based renewable energy systems. Small wind power systems can:
