Abstract
A method and an apparatus are provided for initiating rotation of blades of a wind turbine when wind speed is less than a cut-in speed. A solar powered wind turbine apparatus includes a solar dome with photovoltaic cells, operably connected to a rotor assembly, and an electric motor. The photovoltaic cells convert solar energy from incident sunlight into electrical energy. The electric motor electrically connected to the photovoltaic cells rotates the blades of the rotor assembly using the electrical energy from the photovoltaic cells. The electric motor powered by the photovoltaic cells initiates the rotation of the blades of the rotor assembly when wind speed is less than the cut-in speed, and therefore reduces or eliminates the cut-in speed required to rotate the blades. The blades of the rotor assembly thereafter continue to rotate in response to a force of wind on the blades and/or the powered electric motor.
