Wind, site evaluation and operating income.

The theoretical power that the wind contains, depends on the wind speed, air density and the area over which it flows. Objects and their wind shadows have an enormous negative effect on wind speed and lead to considerably less power in the wind. At higher altitudes, for example on high-rise rooftops, there is far less turbulence. The actual performance, i.e. “what comes out at the end" depends on the following additional factors:

• The cp value (efficiency) of the plant.
• The mechanical loss (drag).
• The electromechanical loss (resistance).

The cp value refers to the efficiency of the wind turbine or the proportion of the wind, which can implement the system into mechanical energy. Depending on the location and or the wind shadows, the developed helix rotor has a cp value from 0.21 to 0.28. Still to deduct is the mechanical loss due to the power transmission and electrical loss during the electricity transmission and transformation into usable energy.

For Example:
On balance, 28% of the theoretical wind power remains for actual use. At 1080 watts of wind power at 12 m / s wind speed, with a rotor surface of 1 m², 280 watts of usable electricity are created.

Put simply, the higher the plant is positioned and the more obstacles that are removed, the easier it is for the wind to access the turbine and the greater the yield.
