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.

Turbine Model Rotor Diameters Available
20kW 10 meters
25kW 12 meters
39.9kW 15.2 meters
50kW 15.2 meters
100kW 21 meters

Polaris wind turbines are designed to meet the IEC 61400 -2 and 1 standards. However we are participating in the new SWCC (Small Wind Certification Council) certification program for our 20kW and 50kW units. Both units are listed on the SWCC web site at (https://www.smallwindcertification.org/certified_turbines.html).This program will certify our turbines against the new AWEA Small Wind Turbine Performance and Safety Standard.
