NeoVenti GmbH

NeoVenti develops and produces wind rollers mounted on roofs. This is an innovative type of small wind turbine that uses both wind and solar energy to generate electricity. The assembly and distribution to the customers is carried out by installation specialist companies for photovoltaic systems.

The wind-solar power combination achieves a rated power of 2 kW. Of this, 1.5 kW is accounted for by the wind rotor and 0.5 kW by the PV modules. The wind roller itself has a length of 2 meters and a diameter of 0.75 meters. The weight of the total unit is 160 kg. An advantage of the horizontal axis can be seen in the manufacturer’s stability over vertical rotors. The speed of the wind roller is between 0 and 400 revolutions per minute. According to the manufacturer, the wind roller starts to produce electricity at a wind speed of 3 to 4 m/s. However, 6 to 7 m/s are necessary for effective operation. In strong winds, no shutdown should be required.

The wind-solar power combination is scalable. Several wind rollers can be placed directly next to each other. This makes them particularly suitable for halls in industry and commerce, wherewinding areas such as the coasts of northern Germany are an advantage.
