Mast Wind Results

Well, I promised you data from the wind study at Mast Academy. 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 takes  readings 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.

    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?

      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...
