How Wind Turbine Output is Calculated
Wind power follows the equation P = 0.5 * rho * A * V³ * Cp, where rho is air density, A is swept area, V is wind speed, and Cp is the power coefficient. The Betz limit caps theoretical efficiency at 59.3%. Annual output uses the capacity factor to account for variable wind conditions. Small turbines typically range from 1-10 kW rated power.
