Wind outputs a month period

Here is a chart of three Skystreams that are in the area.
What I did was go to each turbine today and download the data from them for a one month period. Each turbine is about thirty miles apart from one another. Each turbine is the same brand and size unit, 2.4 kw. But their towers are all different sizes 45', 60', and 120' tall.

What I found to be funny is that the 45' tower did better than the 60' tower. Which I can not figure that out, because the 45' tower has a lot of trees to the NE side of the turbine and the 60' tower has nothing but open space. The only thing that I can think of, is the 60' tower was out balance, which today it seems that I have it balanced right where it needs to be. I guess next month will be interesting to see if it made a difference.

The total kWh for the one month period goes like this:
45' tower - 88.55 kWh for the month
60' tower- 79.52 kWh for the month
120' tower- 209.82 kWh for the month

So as you can see from the chart and from the totals that is always best to get as high as possible with your tower for your wind turbine. We been experiencing some very low winds this summer, lower than previous years. But though that is the case the 120' tower still was over 200 kWh for the one month period.

It will be really interesting to how each one does this winter once the wind really picks up. Which we are starting on the up swing this next month.
