The invention provides an attack angle changeable and resistance type wind-photo complementary generator with a vertical axis, which comprises a generating box, a generator gear, a sleeve gear, a generator, a spindle, a pole bracket cantilever and a blade; the spindle is sheathed with a sleeve, the pole bracket cantilever is fixed to the sleeve and provided with a blade rotating device, the top of the spindle is provided with an aerovane the pole bracket cantilever is provided with a solar battery; the direct current output by the solar battery plate through a photovoltaic controller, low voltage alternate current output by the generator rectified or direct current output by the generator collect together to be charged into a battery pack; the blade rotating device takes the battery pack as a power source; the aerovane is connected to the controller which controls the blade rotating device. The generator of invention is integrated with wind-photo generation and adopts a resistance type vertical axis windmill mode to automatically adjust the angle of the blade according to the wind speed and wind direction measured by the aerovane and ensure that the fan is always in a state that can generate maximum torque, thereby effectively reducing start-up wind speed.
