Hybrid systems wind - solar -battery
off grid and on grid

We provide both solutions also in combination with solar and battery storage systems.
Build up your own added value by own cooling, drying, preserving, heating,
Our special wind turbines with big rotor diameter and according swept area for low wind sites 3.5 up to 5.5 m/s generate more constant energy production over time.
That way it covers more of your demand compared to classical small wind turbines with smaller rotor.
