Südwind - Berliner Windkraftanlagen-Hersteller ist von der Nordex AG aufgekauft worden. Südwind Eigenentwicklungen, wie diese Anlage, haben eine Leistung bis zu 750 kW.
The wind turbine is small. The rating is only 750 kW. Depending on the wind, in the average per year, the wind turbine runs nominal 2000 hours. The annual production is approximately 750 kW * 2000 h = 1500000 kWh. A German household consumes an annual average of 3500 kWh. So the small wind power plant supplies 1500000 kWh : 3500 kWh/household = 428 households
Some years ago I developed electronic controlled drives to adjust the rotor blades, so that with every wind the optimum efficiency of the wind turbine is reached. Today wind turbines with a nominal power of 7.5 MW are built. So more than 4000 households are supplied by one turbine.
