its a nice cheap Chinese 400w turbine. The problem with small windpower is finding “clean air” not near buildings and trees. Thus london is a no for windpower. If you are in the coast or wide open countryside then can make sense. At our mooreing we are maybe 100m from nearest trees on only one side so its working ok here. But still only 10-20w on 20km wind and up to 50-100w on 30km wind. But its 24hours when the wind blows so good compliment to solar in the right location.
