The Trott Bailey University developed this wind turbine training program for residential homes as a course companion to our signature Step by Step Solar course over 5. This wind turbine installation course has blossomed to stand on its own and is now the industry standard for wind turbine installation and certification for wind turbine installers across the globe. We have trained over 900,000 wind turbine installers over half a decade in 120 countries and 75 languages.
