Yes, 15.5 and 18.111 should cover the landscape for all unintentional radiators
& ISM radiators with regards to licensed services, notwithstanding their “test”
results.

Since solar panels are part of an electrical system, the same rules that apply
the RFI from electrical power lines should also apply to electrical power
generation.
I've never heard of a utility successfully argue that their RFI conducted
emissions meets part 15 limits so they're allowed to cause harmful RF
interference to licensed radio services.
That would legalize unlicensed spark gap transmitters as long as they could
meet conducted limits in part 15.
Also, ARRL RFI Book only mentions part 15 for powerline interference if I
remember correctly.

I expect that they fall under Part 18, like home appliances and outdoor
lighting.
