Because of its own design reasons, the power generation of Vertical-axis wind turbines is far less than that of horizontal-axis wind turbines. This problem is a worldwide problem and has not yet been solved. But its advantage is that it can be started in the breeze, beautiful appearance, and not easy to break. Because of the blade, the fan speed can only slow down when it reaches a certain speed, and it cannot continue to run at a high speed. Therefore, the ideal power generation cannot be achieved. Most of the wind turbines are used in wind-solar hybrid power generation systems. The combination of wind and light can achieve better results and ensure the stability of power generation.
