Onshore wind turbines

Onshore wind turbines are installed individually, and in groups called "wind farms". Wind turbine systems comprise a tower, hub and blades (the rotor), and nacelle (houses the generator. They are typically attached to a reinforced concrete foundation. Based on the wind characteristics of the site, these structures are generally designed to conform to the International Electrotechnical Commission (IEC) 61400-1 wind turbine design class.
