Inside Freen-9:
A Look at Innovation
-
Easy-to-Install Foundation
Prefabricated, non-buried foundation for simple and stable installation.
-
Lightweight Blades
Blade proportions ensure optimal aerodynamic performance, reduced vibration, and enhanced stability while remaining wildlife- and neighborhood-friendly.
-
High-Efficiency Generator
No gearbox. A permanent magnet generator, adapted from our proven models, ensures reliable operation with minimal friction losses.
-
Compact Rotor
The compact rotor size is tailored for home environments, delivering power with less noise and a visually refined design.
-
Low-Friction Components
Direct drive design reduces energy loss and extends lifespan.
-
Slow Rotation, Maximum Safety
Operates at 90 RPM – slow enough to ensure safety for humans and animals and maintain quiet operation.
-
No Wind Orientation
Thanks to its vertical-axis design, the turbine performs efficiently regardless of wind direction — no active orientation needed.
-
Monopole Tower
Easy to install, variable height available for different application types.

Annual Energy Production
Annual energy production (AEP) is based on a Rayleigh wind speed distribution, K=2, t=15°C, P=1013 mbar, ρ=1.225
Annual Energy Production (AEP) values and power curves are indicative only, calculated under standardized assumptions. Actual energy output depends on site-specific wind conditions, installation height, turbulence, grid availability, and operating conditions, and is not guaranteed.
FREEN owns the design and technical documentation of the turbine.
