Wind turbine information of horizontal and vertical

Horizontal Vs Vertical Wind Turbine

Wind turbines mainly have two designs: horizontal axis(Like our Sunning  Wind Turbine) or vertical axis.
Horizontal-axis wind turbine generally has three or five blades propeller that catches the windward. Vertical wind turbine has a set of blades that spins  around a vertical axis. Each type has its advantages and disadvantages and is suited to different installing environments.

Wind Direction and Speed
In order to work properly, the horizontal-axis turbine needs the wind to flow at a right angle to the blades. If it blows from a different direction where  the blades are facing, the turbine gets much less energy from the wind. To adapt changes of wind direction, horizontal turbine has a yaw drive that rotates  the unit’s direction. Vertical turbine runs regardless of wind  direction, making it better-suited to urban areas among tall buildings where has limited  space to install.

Wind Energy Efficiency
Horizontal-axis wind turbines can convert more wind energy into useful mechanical power because the blades are perpendicular to wind direction so the blades  can pick up more energy throughout their range of movement. By comparison, vertical-axis wind turbine suffer an disadvantage of low efficiency in transfering  energy from the wind cause it can only drag wind on the front side.

Market Preference
Although the vertical-axis turbine has a few advantages over the horizontal design, different scales of energy users have chosen the horizontal-axis  generators，leaving vertical-axis generation to small commercial or individuals  uses. The horizontal axis is simpler to understand and has lower cost, can  meets the expectations of end-users. Vertical-axis generators have  historically been the object of exaggerated claims and higher cost causing doubt for  potential users.
