Hi Bryan, great question. The lack of a utility connection does not change RSD requirements under the NEC. You'll still need to follow NEC 690.12 language.
Thanks for the comment. The new exceptions are also specific in eliminating some of the conductors we must control. The first one eliminates circuits within free-standing structures from the entire 690.12 requirement. The second exception then goes on to say for circuits from those free-standing structures that remain outside a structure, we are not required to control those conductors. So, as long as we don't enter the building with those PV circuits, we'll meet the 690.12 requirements under the 2023 language.

What about in the case of a completely off grid standalone system (residential)? Is RSD required assuming we have roof mounted panels?

The language on or in is pretty specific. Need to have an exeption for total ouside to address this issue. On or in language still says on or in...
