Aerogen 2 Wind Turbine Hot

Aerogen 2 Wind Turbine

A very small wind turbine designed primarily for battery charging on boats or small contributions to household electricity and other low power land applications.

To cope with constantly varying conditions such as those aboard a yacht or weekend cruiser the Aerogen series can withstand very high winds and general adverse weather.

Swept area

The Aerogen 2 has a blade diameter of 0.54 metres. This means it has a swept area, or capture area of 0.23 square metres. This is all important when comparing wind turbines, since it directly relates to the amount of passing wind energy the turbine blades can intercept.

Aerogen 2 power output curve

The graph below shows the power produced (in watts) for the Aerogen 2 at different wind speeds, based on data supplied by the manufacturer.


The green line shows the actual output that the wind turbine achieves at the given wind speed, according to the manufacturers.The dashed line in the graph shows the theoretical maximum energy that this turbine could extract from the wind, according to Betz's Law (59.3%). At a typical wind speed of 5 m/s, the Aerogen 2 is extracting 6.67 Watts of power from the wind, which is an efficiency of 37.88%.

If you want to install a wind turbine, it is very important to measure how much energy you might produce.

How efficient is the Aerogen 2?

Wind turbines can only convert some of the energy in the wind into electricity. The graph here shows how efficient the turbine is across the range of wind speeds you might get.

The orange line in the above graph shows the efficiency ranging from 0 to 1. The grey line is the previously mentioned maximum efficiency - The Betz Limit. If this limit is exceeded, the manufacturer's claims are not to be trusted!

While these graphs give an indication of the instantaneous power and efficiencies you might expect from the Aerogen 2 turbine, working out annual power production is more complex.
