These turbines run from above and from bottom on magnet ball bearings. because of this there are considerably fewer friction losses compared to traditional axle arrangements. Further optimization is done by it use of light weight aircraft aluminium and recycled plastic.
With a low weight, ranging from 25 kg for the 1kW, 400 kg for a 5 kW and 860kg for a 10kW, these units are suitable to place on roofs. A solar panel weighs for comparison, without ballast, approximately 20 kg per 300 Wp.
turbines also take less place on a roof. These are on towers placed on the roof of at least 1 m height. This allows for several turbines to place on a roof or to combine it with for example other technical installations on your roof.
A 10kW turbine has approximately a roof surface area of 25m².
The turbines can be stacked up to 3 modules!
