A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.
Wind flows over the blades (similar to the effect on airplane wings), which causes the blades to turn.The difference in air pressure across the two sides of the blade creates both lift and drag. The blades are connected to a drive shaft that turns an permanent magnet generator, which produces (generates) electricity.
The electricity output from the wind turbine convey to the controller( can be together with an unloader), then connect with the inverter or load system. If your system is on-grid, the inverter is must need, electricity convey from the inverter to the power grid, if your system is off-grid, the inverter is not necessity.
And in some Wind-Solar hybrid system, we can also use the solar panel together with the wind turbine, if so, when there is no enough wind flow, the solar panel can play a role.
