If you can get anchor bolts in, you can weld on a 1" think plate with
gussets to the bottom of the pole. We've had to do this a couple of
times in rock. We'll pour enough concrete to get a level base, but the
bolts are epoxied into holes in the rock. A good epoxy anchor is
stronger than the bolt itself. We've also done combinations, where we
can only get 18" of concrete over the rock, then we epoxy in rebar to
tie the concrete to the rock, and J bolts set in the concrete to bolt
the base plate to.

A pole mount can be part of a virtually tracked array system. Gives
long hours of power, if that is the reason she wants this. It can be
angled for SW 9 months and go south for the winter. It needs another
array or combo of arrays for SE and S. If it is some other weird
reason she wants this, I would just do it and bill in advance. Tell
her only death and taxes are guaranteed!
Somebody else will have info on a pole mount with ballast. That would
be interesting!
There is no danger to your screw guy right?

Hi Wrenches,
We typically use SunModo ground mounts with ground screws which we
can put just about anywhere as our screw guy has a rock drill.
We have one customer who is dead set on a top of pole mount array and
will not settle for a typical ground mount with multiple posts.
There is shallow ledge all over her property and we feel that digging
multiple large holes to find one spot where we might be able to get
deep enough would be a waste of time and resources. We have called
an underground locator who uses ground penetrating radar and he
scanned a few spots, but was unable to give us a good location based
on soil types.
What are you guys doing in this situation? Are there any
alternatives, such as a pole mount with large base and ground screws?
I hate saying it can't be done!
Thanks!
Ben
