Well, I promised you data from the wind study at MastAcademy.
We took two readings in two separate areas around the campus. I’ve taken images
from google maps and labeled the two spots. Site A the readings were taken for
about 10 days, funny enough even thought it was in the middle of a big field,
so therefore seemed more open, in point of fact, the wind resources there were
pretty much zero. Our second reading was taken for about 2 weeks at site B –
seemingly a noisy or crowded area (parking lot, buildings to the east and
north, trees to the west), however, the winds were given a nice opening between
the trees and the buildings from bay to ocean so the readings were much
stronger.
The anemometer
takesreadings every tens minutes… the
below image is just a simple graphical representation of the data – Purple is
the average minimum, Blue average and Yellow max speed. The running average for
the period was about 3.6, the min was about 1.1 and the max a bit more than 5.
I don’t want to bore you with numbers but the basic gist is this…
On the average low,
on a day to day basis there was enough wind for the turbine to reach “On”
speeds
At a running
average of 3.6 a turbine would run at approximately 55% max output.
So that’s not too
bad, while we would rather see more wind, this shows that there is enough wind
and at what speeds it would be economically feasible to install a turbine, not
ideal, but not bad.
Keep in mind, this
is in Southern Florida where the big wind maps say Florida has near zero potential for wind
power – so the study serves also to prove the point that small wind is very
different from the large scale utility scale wind farms that we’re all kind of
familiar with.

Ken: Thanks for follow thru. So with 3.6 wind turbine, it is worth considering adding a wind turbine to my house when I do my electric upgrade? If my home (and us) use 57KW/day, how many KW would this turbine be good for do you think? Reply to this

Blake - Sorry it took me so long to get back to you with this post etc... small wind is very site specific, so it's really hard to give an estimate of power generation without knowing where you are. That being said, I think the above test does show that for coastal communities small wind works. Running a test is pretty easy... I think what I'll do is post a quick entry on getting started with testing so if you're interested at least I can give you some helpful pointers... Reply to this
