We've only had to use Schedule 80 out of the concrete, but never
otherwise had a problem. Is his concern the structure of the concrete?
It's ballast, not a pier that takes a compressive load. We've never had
a problem in 2 decades.

Drake,
This is a very common way to install this conduit, so I really would
like to know how this inspector would route wire from the top of a
pole down into a trench while passing through a concrete footer.
We have inserted a one-size larger conduit elbow when we pour the
concrete which sticks up above the top of the concrete and out the
side wall of the dug hole for the concrete pour. Then after the
concrete has set, we route the conduit from the solar module junction
box down the pole and through the elbow. This provides a larger and
more rugged conduit that is slightly larger than the conduit carrying
the wiring which protects from trimmers and mowers.
Keep us posted,
