Key Benefits

Compact vertical design

Our products are easy to install in confined spaces, on rooftops, or other unconventional locations.

Few friction components

All Freen turbines use a minimum of friction elements to avoid heating, wear and tear, as well as energy dissipation.

Low noise pollution

Our turbines are suitable for deployment in the vicinity of residential buildings and in densely populated areas.

Eco-friendly production

Our lean production process and use of lasting, durable materials ensure a low carbon footprint.

Low cost of maintenance

Owing to our innovative design, our turbines boast an average life span of 20 years with minimal maintenance.


While other turbine makers target higher-end energy projects, we effectively address the pain points of up-and-coming energy operators, land owners, farmers, telecoms, and other consumers looking for greater flexibility in planning, deploying, and scaling their power generation capacities in various conditions.

Our products boast the best-in-class energy conversion efficiency among all compact Darrieus turbines and small wind turbines in general. Designed for all-weather low-altitude operation, Freen turbines effortlessly handle turbulent air currents and withstand strong winds owing to the soft and flexible wings, as well as our durable and robust design.
