Abstract: A multirotor wind turbine (1) comprising a tower structure (2) and at least one load carrying structure (3, 4), each load carrying structure (3, 4) being arranged for carrying two or more energy generating units (5, 7) comprising a rotor (6, 8). At least two of the rotors are upwind or downwind rotors (6), the energy generating units (5) comprising upwind or downwind rotors (6) being arranged with their centres of gravity at a first distance behind the tower structure (2) along a direction of the incoming wind, substantially at the same vertical level, and at opposite sides of the tower structure (2) at substantially the same second distance to the tower structure (2) along a direction substantially perpendicular to the direction of the incoming wind. The multirotor wind turbine (1) is self-yawing, even under turbulent wind conditions.
