The differences between horizontal axis wind turbine(HAWT) and vertical axis wind turbine(VAWT)
| Item | HAWT | VAWT |
| Design and Orientation | The rotor shaft is horizontal, and the blades rotate parallel to the ground. They typically have a tall tower with blades facing the wind. | The rotor shaft is vertical, and the blades rotate around a vertical axis, resembling an eggbeater or a spinning top. |
| Efficiency | Generally more efficient at capturing wind energy, especially in areas with consistent wind direction and speed. | Less efficient due to drag and lower aerodynamic performance, but they can capture wind from any direction. |
| Wind Direction Sensitivity | Requires a yaw mechanism to turn the rotor into the wind, making it dependent on wind direction. | Omnidirectional, meaning it can capture wind from any direction without needing adjustment. |
| Space and Installation | Requires more space between turbines to avoid wind shadowing and turbulence. Often installed in large wind farms. | Can be placed closer together, making them suitable for urban or confined spaces. |
| Maintenance and Durability | Maintenance can be challenging due to the height of the turbine and the complexity of the yaw and pitch systems. | Easier to maintain as most components are closer to the ground, but they may experience more wear and tear due to lower efficiency and higher stress on blades. |
| Applications | Commonly used in large-scale wind farms for commercial electricity generation. | Often used in small-scale or urban settings, such as rooftops, where space and wind direction variability are concerns. |
| Noise and Aesthetics | Can be noisy and visually intrusive due to their size and blade rotation. | Generally quieter and more compact, making them less obtrusive in residential areas |
| Cost | Higher initial costs due to complex design and installation, but lower operational costs over time due to higher efficiency | Lower initial costs but may have higher operational costs due to lower efficiency and maintenance needs |
| Summary | • HAWTs are better suited for large-scale, high-efficiency energy production in areas with consistent wind | • VAWTs are ideal for small-scale, urban, or variable wind conditions where space and directional flexibility are priorities. |
