In theory, the efficiency of vertical axis will be higher, but in practical applications, horizontal axis wind turbine has the advantages of simple structure, low price and mature technology .
Generally speaking, the vertical axis has a low rotation speed and is not affected by changes in wind direction during operation; the horizontal axis has a higher rotation speed and is equipped with a corresponding direction adjustment device. It looks good and can be used as a landscape.
If you want to use it, it is recommended to choose the horizontal axis;
