Well, it looks nice but in that location it will be unlikely to get much clear wind. You cannot really judge that turbine's performance in that setting.

Surrounded by tall "stuff". Even if it is open land behind the photographer the turbulence would rob all the power the wind might have.

Be much easier for you to get useful test data by spinning it with a rope around the axle, a drill or something in bench type tests.

What feels like a nice strong breeze will not be the same as an open field breeze due to turbulence from air hitting all that stuff around the turbine.

The turbine looks nice. I suggest you haul it out in the country someplace open and set it up you might be surprised at how quick it might spin up in open air wind.

Don't get discouraged, I had the same problem with a couple turbine experiments in close to the buildings here and I am in a very rural area.
