Small wind, or domestic wind, refers to small and medium-sized wind turbines, from 100 watts to about 20 kilowatts, with mast not more than 12 meters.

Beyond that, we speak either of commercial wind turbines (between 12 and 30 meters) or of industrial wind turbines (more than 35 meters). Being pale, of the type Proven or type Inclin, the small wind is developing in both rural and urban. To install a wind turbine greater than 12 m, a building permit must be submitted to the town hall. For a wind turbine less than 12 m, no need for a permit, you must make a declaration of works.
