Polaris America turbines are made in the United States, New Jersey to be exact. Current wind turbines are being designed to meet the IEC 61400 -2 standards. However we will participate in the new SWCC (Small Wind Certification Council) certification program. This program will certify our turbines against the new AWEA Small Wind Turbine Performance and Safety Standard.
Your total Community Wind Provider” – From 20 kW to 100 kW, Polaris has a size to fit your requirements with a proven technology that delivers the next generation of wind power needed for diverse energy applications.
