Why a small wind turbine on a UK house cannot compete with rooftop solar: the best buildable domestic blade tops out at Cp ≈ 0.49 (Reynolds-limited, not design-limited), and only about 3% of GB households have the wind to match a 4 kWp array. BEM, guarded aerofoil optimisation, and a dwelling-weighted national resource analysis.
