WES 18/80

Introduction

The WES80 is a two bladed, high performance, reliable 80 kW midsize wind turbine with a rotor diameter of 18 meters with a new cover. The mechanical part of the WES80 is based on the original, proven design from 1983. For the electrical parts providing power conversion and control, the latest technology is used.

WES80 turbines are manufactured and exported by WES in the Netherlands, and are sold, installed and maintained all over the world by a global network of certified and trained dealers.

The WES 80 is also available with our elegant new cover.
