I tried to tell people this before the pilot started, but some solar over-producers were insistent on going ahead anyway. The more interesting thing would be to try to tack on another utility program, NEM Aggregation, to push some of your generation to the sub-meter account. I don't really expect that they would let you do that with a sub-meter, but it would be worth a shot if Edison has that program. As an aside, if NEM Aggregation or Virtual Net Metering existed at the time, I would have built my house with a second meter socket and a garage sub-panel. At the time, there was no way for a Solar NEM to put credit toward an EV meter. I'm pretty sure that is possible today with PG&E.
