Spoiler for a wind turbine blade

A wind turbine, comprising:

• a plurality of rotor blades attached to a hub, wherein at least one rotor blade comprises a spoiler mounted on a surface strip of the rotor blade, which surface strip comprises a length along a suction side of the rotor blade and/or a length along the trailing edge of the rotor blade,
• wherein the spoiler comprises
• a base member, which base member comprises a mounting face for mounting onto a surface of a rotor blade, and
• an aerodynamic member for detachably connecting onto the base member.

A method of constructing a wind turbine, comprising:

• manufacturing a rotor blade;
• mounting a base member of a spoiler onto the rotor blade;
• connecting the rotor blade to a hub of the wind turbine;
• connecting an aerodynamic member of the spoiler onto the base member;
• wherein at least the mounting of the base member onto the rotor blade is performed prior to the connecting of the rotor blade to the hub.
