There are all kinds of paradoxical issues involved, and jaggedben knows it... which I believe is why I didn't "respond" in that other thread.Are you saying it is a service?
That is at best up for debate.
Ultimately you could say none of the conductors or equipment solely for the PV system are part of a service because...
The purpose of the conductors and equipment is to deliver electric energy from the PV system. All the other arguments are rendered moot by this one definition.Service. The conductors and equipment for delivering electric
energy from the serving utility to the wiring system of
the premises served.
