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.
