Power Production
Thanks to Windside's unique design and unparallelled engineering work Windside wind turbines are probably the most efficient wind turbines in the world. How is this possible?
- Windside wind turbines have an abiliy to take advantage of even the lowest wind speeds (1-3 m/s).
- The wind direction is not a significant factor for Windside, since the wind catches the spiral-shaped vanes always from the right angle.
- Windside will carry on generating at wind speeds of 40 ms, 50 m/s or 60 m/s depending on the model.
- Windside efficieny curve is across a very wide range of wind speeds.
KWh production
We at Windside belive that the energy production should be informed in kWh/year basis and this production figure should be based on measurements done in real life circumstances.
Commonly used maximum rated power has very little to do with real life results and therefore it is important to find out how many kWh the turbine is like to produce on annual basis at different wind speeds.
We at Windside want to be honest with our customers and we use real life measurements when informing the expected annual output of the turbines. Please see below
| Annual kWh output at average wind speed of 5 m/s |
Annual kWh output at average wind speed of 7,5 m/s |
Annual kWh output at average wind speed of 10 m/s |

The table above is an estimation based of real life measurements at less than 5 m/s average wind speed. It is challenging to say in advance how much energy the turbine can produce since there are several factors affecting the production. Things like wind speed, installation place, height of the mast, surrounding buildings and trees, turbulence, air density and wind shear.
