Vertical axis wind turbines (VAWT) installed in a green area

Savonius wind turbine VAWT installed on the rooftop

Savonius Wind Turbine (VAWT)

One of the most robust wind turbine types, operating on a drag-based mechanism. Savonius turbines feature very high starting torque, enabling operation even at low wind speeds.

  • Ideal application: Areas with irregular winds, telecom stations, and projects where reliability and quick start-up are priorities.
  • Key advantage: Simple S-shaped structure, minimal maintenance, and high resistance to storms.
H-Rotor Vertical Axis Wind Turbine (VAWT) installed on a building rooftop

H-Rotor Vertical Axis Wind Turbine (Giromill)

H-Rotor turbines operate on a lift-based principle and feature tall vertical blades connected to a central shaft via horizontal arms. This design delivers higher efficiency compared to conventional models.

  • Ideal application: Higher power generation in semi-industrial areas, parks, and large commercial complexes.
  • Key advantage: High energy efficiency and excellent balance at medium to high wind speeds.
Helical Vertical Axis Wind Turbine (Helical VAWT) installed in the city

Helical Vertical Axis Wind Turbine

Helical turbines represent the most advanced aerodynamic form of VAWTs. The twisted blade design ensures uniform torque distribution and virtually eliminates vibration.

  • Ideal application: Rooftop residential installations, street lighting, and noise-sensitive environments.
  • Key advantage: Extremely smooth operation, extended bearing lifespan, and an attractive,
  • decorative appearance.
Implementation of the combined (hybrid) project of Archimedes wind turbine (VAWT) and solar panel installed on the roof of a residential building

Archimedes Wind Turbine

Inspired by the Archimedean spiral and mathematical principles, this turbine’s unique form maximizes airflow capture and delivers one of the highest energy conversion efficiencies among small wind turbines.

  • Ideal application: Locations requiring maximum performance from low wind speeds.
  • Key advantage: One of the quietest wind turbines in the world, with very high efficiency and, in some hybrid models, the ability to track wind direction.
