Certification of small wind turbines involves three distinct steps: establishing hardware performance standards, conducting tests, and operating an independent certification body.  All parts are necessary to implement certification. However, SWCC only conducts the third step. The SWCC is an independent certification body created to serve the North American market. SWCC issues certified turbines easy-to-understand labels for Rated Annual Energy Output, Rated Power, and Rated Sound Level. The label also confirms that the turbine meets durability and safety requirements. As turbines are certified, SWCC publishes Power Curves, Annual Energy Performance Curves and measured sound pressure levels for each model certified.
