It's very simple The swept area is the plane of wind intersected by the generator As such the height of the blades times the diameter of rotation will produce the square meters or feet of the swept area Empirical Reality Let's look at the Wind

To help with this process small wind site assessors typically develop a wind rose which shows the wind direction distributions of a given area The wind rose divides a compass into sectors (usually 8 or 16) and indicates the average wind speed average percentage of time that the wind blows from each direction and/or the percentage of energy in the wind by sector Wind roses can be

It is unfortunate to see how well marketing for small wind turbines is working I often see people post questions on forums where they are looking for a wind turbine "with a low cut-in wind speed" Depending on whom you ask the cut-in wind speed is either the wind speed where the turbine starts turning or the wind speed where it starts to produce some power For most wind turbines it is

Wind Energy Math Calculations Measuring the Swept Area of Your Wind Turbine Why is This Important??? You will need to know the swept area of your wind turbine to calculate the total power in the wind that hits your turbine Remember the Power In The Wind Equation 3 P = Power (Watts) ρ = Air Density (about 1 225 kg/m3 at sea level) A = Swept Area of Blades (m2) V = Velocity of the wind By
