[RE-wrenches] Tall pole mount

[Dana]

Yes, use an engineer, basically you are creating a wind
turbine or equivalent type of structure. 

 

Works fine guyed but you need to have enough pole base
weight, guy point weight, cables and pole to withstand the
stresses. We went 27' height to the top of pole mount then
the owner doubled the # of panels and the  Uni-Rac aluminum
mount cracked, requiring the removal of the whole mess and
all sorts of additional bracing and welding at 25' AFG. 

 

Obviously, it is not good to field re-engineer, esp. when
you do not have a clue as to what you are doing.

HI Holt,

 

I've done a pole as you are describing. 

It also had a tracker on it.

 

3 or 4 sections of scaffolding were used to install the
equipment, although if better access a lift truck would have
been better. And you'll need equipment to move and install
the pole.

 

The pole was guided, and sounds like yours in the trees so
not a lot of exposed wind loading.

 

 

Nothing difficult just more:  money, time, equipment, and
parts.

 

One note, if you are installing a tracker, I might install a
ladder and a platform on the pole to make repairing  the
tracker quicker and easier.

Situation:  Client has limited locations for array due to
trees. There is one spot that would work IF pole mount is
20-25' (that would put the array top edge at 30'+). Will
need to incorporate tracker to maximize production. Will
definitely be consulting structural engineer.

 

Questions: Anyone tried this? Comments or lessons learned?
