![]() You want to place the turbine in the windiest spot you can. There are two things to keep in mind when deciding on the perfect location for your wind turbine, and these are wind and distance: ![]() So, a 15 kW turbine will produce roughly 22,338 kWh per year, for example (8,760 x 15 x 0.17). Kilowatt-hours per year = 8,760 (number of hours per year) x power rating (kW) x capacity factor Using this average of 17%, you can calculate an estimate of your annual electricity production using this formula: average capacity factor of 17%, as per the Department of Energy’s 2018 stats. Once you have that information, simply plug it into this formula:Ĭapacity Factor = (Average Wind Speed) / (Rated Wind Speed)Īlternatively, you can use the U.S. To calculate your capacity factor, you need to know the average wind speed in your area. Your capacity factor measures how much wind energy you can realistically expect to generate at your location. ![]() You can find this information on the appliance’s energy label or in the owner’s manual.Īlternatively, go back through your old energy bills to get a good grip on past usage. To calculate your energy usage, simply add up all the kWh (kilowatt-hours) from each appliance and device in your home. This will give you a good idea of how much power you need to generate and what size turbine you should look to buy. The first step in choosing a suitable wind turbine is calculating your energy usage. You can shorten this timeframe if you live in an area with high wind speeds and/or receive government incentives for installing a renewable energy system. In terms of return on investment, wind turbines typically take between five and 15 years to pay for themselves. The ongoing cost of maintenance is relatively low, averaging around $200-$300 per year. So, assuming that you want the turbine to supply 100% of your electricity, you might need a 15 kW turbine (depending on your house size and energy consumption), which would cost approximately between $30,000 and $75,000. ![]() The American Wind Energy Association (AWEA) estimates the upfront cost of a wind turbine to range between $2,000 and $5,000 per kilowatt of power capacity.
