MW against rotor diameter (m)
Rated power / swept area (W/m²). Shaded bands show indicative IEC wind classes.
Specific power = rated power / (π·D²/4). IEC bands are indicative, not normative: Class I > 350 W/m² (> 8.5 m/s), Class II 280–350 W/m² (7.5–8.5 m/s), Class II–III 230–280 W/m² (6.5–7.5 m/s), Class III/S < 230 W/m² (< 6.5 m/s). Data: manufacturers. Chart: Windletter.
