Determining Annual Wind Turbine Power Output – A Simple Formula Based Upon Blade Diameter and Average Wind Speed at Your Location
Are you looking to lower your electric bills by using wind power as alternative energy? You're not the only one, millions of people are looking at going green. Moving on wind power will reduce your carbon footprint thus helping the environment and reduce your energy costs and dependence on foreign oil.
If you're looking wind power you'll probably want to know how much power a home wind generator actually produces. To determine a realistic approximation what power could be built on your property there are some rules and guidelines that you can use.
To determine the estimated annual energy output for a small wind turbine, you can use the following formula:
(Yearly output in kilowatt-hours) = (0.01328) x (blade diameter
feet) ^ 2 x (average wind speed in miles per hour at your location) ^ 3
The simplified formula is: Power = 0.01328 (D) ^ 2 (V) ^ 3
There are two factors have a significant impact on energy output, blade diameter and wind speed. Increasing the blade diameter increases the energy output as a quadratic function. For example, If you increase the blade diameter by a factor of 2, the energy output will increase 4-fold.
Although diameter blade has a dramatic impact on energy output, wind speed is more important. Energy is a cubic function of wind speed. For example, if the wind speed is doubled, the energy output will increase by a factor 8. Thus, the wind speed is the most important consideration in the smaller wind turbine energy production.
The above equations and discussion thus indicates that your money is better spent on raising the height of your tower or choosing a better location with more exposure than a wind generator with larger diameter blades.
