  The windmill 10 is a vertical axis windmill whose rotation axis is perpendicular to the wind direction, and does not require control of the wind direction. Moreover, even if the wind in the housing | casing 14 is disturb | confused by mounting a solar cell array by making the windmill 10 into a vertical axis type windmill, the windmill 10 can be efficiently rotated. Bearings (not shown) that support the upper end and the lower end of the rotating shaft of the wind turbine 10 are provided on the upper surface (ceiling portion) and the lower surface (bottom plate portion) of the casing 14, respectively. The generator 12 generates power by the rotation of the windmill 10. The generator 12 can be installed on the upper surface of the housing 14, for example.

  The casing 14 has a rectangular parallelepiped box shape formed of metal or resin, and is provided with openings 14a on four side surfaces so that wind can pass therethrough.

  The support portion 16 is provided on the housing 14. The loading plate 16 a constituting the upper surface portion of the support portion 16 has a predetermined inclination angle θ with respect to the upper surface of the housing 14. The inclination angle θ is determined based on the latitude of the installation location of the wind turbine generator 1 and the structure of the solar cell array supported on the support unit 16.

  The support portion 16 is made of metal or synthetic resin. The material forming the housing 14 and the support portion 16 may be the same or different. The support part 16 and the housing | casing 14 shall have the weight-proof performance which can endure the load of a solar cell array.
