I did this on one property with two meters on different
buildings. There were no problems.
We have been considering a design that would have a central ground
mount array in a favorable location with different sub arrays feeding
different inverters in different houses that are in the vicinity of
the array. I think that so long as all easement details are worked
out, it should be permissible.
