Small Wind Turbine Testing
Testing of small wind turbines to international standards is one of the principal ways we can insure that small wind turbines can do what their promoters claim. For decades manufactures of small wind turbines could say whatever they wanted about their wind turbines and there was no way to hold them accountable. Today–after nearly three decades of effort–there are standardized tests for measuring the performance of small wind turbines and standardized ways of reporting this performance. No one should ever buy a small wind turbine that has not been tested to international standards and the results of those tests published for the world to see.

Power Performance Test Report for the Windspire by Windward Engineering
By
Paul Gipe
The Windspire is a vertical‐axis gyromill. The H‐rotor is 1.22 m (4 ft) in diameter by 6.1 m (20 ft) tall, capturing a swept area of 7.43 m2 (80 ft2). The data presented in this report was collected during a power performance test conducted by Windward Engineering from 21 October to 28 October 2011. The test was conducted at Windward Engineering’s Spanish Fork, UT test facility.
