ed5000, congratulations! Most people I know had to wait far longer for PG&E to come out and install their new meter, all the while the old meter was not recording any benefit from the active solar for the owner.
Good luck on figuring out an advantageous rate structure - https://www.pge.com/tariffs/electric.shtml
Need to study your existing consumption, factor in projections with your new solar system, and do the math to choose the least of the evils offered. Since you'll be Time Of Use (TOU) a lot depends on your particular daily schedule.
Here's their blurb on EV rates:https://www.pge.com/en_US/residential/rate-plans/rate-plan-options/electric-vehicle-base-plan/electric-vehicle-base-plan.page
I have E-6, but it's not offered any more. My daytime peak rate is 45.7¢/kWh and my lowest rate is 17.9¢/kWh ... thank goodness, with my amortized 11kW solar I don't pay anything! They're wising up, reacting to the duck curve, and we'll all be screwed as they revise the rates...
Did you figure in electric cars as part of your amortization calculation? How many years? My own predicted was 17 years but in actuality it broke even in seven.
It'll be interesting what happens if PG&E is found liable if their downed power lines started all those fires...
