Should I Choose Horizontal Axis or Vertical Axis Wind Turbines?

As a leading company in the new energy industry with over a decade of experience, we often receive inquiries from customers about whether to choose horizontal axis or vertical axis wind turbines.

Vertical axis wind turbines are usually more favored by customers because of their more aesthetically pleasing design. One of our customers believes that vertical axis wind turbines are better because they have a cylindrical design. He thinks that this type of wind turbine can better accept wind from all directions. In fact, the greatest advantage of vertical axis wind turbines is their quietness. If your installation site is close to a residential area, we recommend using vertical-axis wind turbines. They are very quiet, aesthetically pleasing, and can also be part of the urban landscape while generating electricity.

When customers want higher power generation, we usually recommend using horizontal axis wind turbines. It relies on the mast at its tail to automatically face the wind, which means it can better capture the wind direction and generate electricity more efficiently by utilizing wind energy. On the other hand, the technology of horizontal axis wind turbines is more mature. Under the same power, they are lighter in weight and have a lower economic cost.

Why Are Vertical Axis Wind Turbines More Expensive Than Horizontal axis Ones?

Every time we quote prices for vertical axis wind turbines to customers, they always say they are expensive. As a company that never falsely labels the power of generators, the price of our vertical axis wind turbines of the same power is twice or even three times that of the horizontal axis wind turbines.

The most crucial factor causing the price difference is the blade. Due to the difference in design, the rotation directions of the generator shafts of the two wind turbines are completely inconsistent. The horizontal axis is parallel to the windward side, while the vertical axis is perpendicular to the windward side.

For a vertical axis wind turbine to achieve the kinetic energy required by the generator, it needs greater kinetic energy. Therefore, vertical-axis wind turbines require a certain length and weight of blades to enable the generator to reach its working speed. Take a vertical axis wind turbine with five blades as an example. In a certain wind direction, four blades are helping the wind turbine rotate, and the remaining blade is the one that generates resistance to the wind turbine's rotation.

Of course, there are also some companies in the current market that like to engage in price wars and sell wind turbines with false power. For instance, if you need a 5kw wind turbine and they offer you a quote for a 2kw one, telling you it's a 5kw one, customers are often deceived by their low prices and end up buying a wind turbine that is marked as 5kw but may actually be less than 2kw, far from meeting their expected power generation capacity.

Our company is committed to manufacturing wind turbines with genuine power. If you think our prices are too high, please compare the parameters of our products with those of other suppliers' products of the same power, especially paying attention to the length/diameter and weight of the blades to avoid being deceived.

Different situations require different wind turbines, which depends on the customer's environment and needs. If you also want to use clean energy such as wind power, photovoltaic power and hydropower, please contact us.
