Testing and Certification

Windspire Energy is committed to independent, third-party testing. We implemented real world product testing at Windward Engineering’s small wind test facility in Spanish Forks, Utah, starting in the fall of 2007, with testing continuing to date.  The Windspire is put through turbulent, high wind testing to honestly rate the product.  This level of testing is unusual and undertaken by few companies in the small wind industry.

Standards and Certification

The American Wind Energy Association (AWEA) recently created a set of standards and a certification process for small wind turbines. In the next 12-18 months the Windspire will be tested to these standards through a grant from the National Renewable Energy Laboratory (NREL).  A notice of intent to certify has been filed with the Small Wind Certification Council.

The Windspire inverter received ETL certification in March of 2008 and has kept this certification up-to-date. The ETL certification includes UL 1741 and IEEE 1547 testing for the US and Canada.
