Blade solidity is one vital parameter in aerodynamic behaviour, it is a ratio of blade chord length to pitch expressed by an equation,
Tip speed ratio
is given by,
Tip speed have direct impact on rotor solidity, if tip-speed gets increased solidity gets affected hence tip-speed will be lowered to maintain solidity. As solidity is one of the important parameters which greatly affects horizontal axis wind turbine. Hence maintaining good solidity is important for wind turbines.

Yaw winds impacts turbine system, whenever yaw winds change turbine is set to move accordingly by system installation between nacelle and tower. It works fine in small and medium range turbines as yaw wind speed is sufficient to turn turbine to match with wind speed. In case of big turbines yaw winds will be having limited force, which will be hard to rotate the system to match with wind direction. In small turbines yaw winds can speed up direction change which results in droop cable damage and teether motion in order to minimize the damage hydraulic damper are installed in small turbines which prevents damage to turbine drooping cable and also minimises teetering motion issue.
