So, you figure that, with "enough" PV over-production, considering the added cost of installing the extra meter, and the (possibly?) extra monthly meter fee, that just staying on the standard whole-house, non-TOU (-D?) rate is best?
IF you have enough over-production (annual net) to cover your EV, then you are better off with a single meter on DR. You can net out $Zero$ for the year, or even get a few pennies back for surplus. In this case, if you opted for the dual-meter (subtractive) Experimental rates, you'd have more overproduction and a monthly bill for the EV use. Even at super-duper-off-peak, it appears the Solar overage wouldn't be paid out at a higher rate, so you'd have to pay the difference. Not a win.
If I was OVER-producing reliably, with enough to cover the EV, I'd stay off the second meter (but still join EV Project).
Conversely, if I am confident that Solar won't cover all my DR use anyway, then I'm certainly better off on the Experimental rates. Assuming I charge off-peak, the electricity will always be the same or cheaper than additional (marginal) DR electricity. If the EV would push you into the 130%+ brackets, then it's certainly a win to go Experimental rate. This is my situation.
Now, the part most people don't know is that you CAN join the EV Project, and decline the second meter keeping the SDG&E arrangement you already have. Then you get the free Blink charger, installation, and data monitoring at the same electric rate you would pay anyway. Worth a thought.
