When I finished my SC PV solar install, I then had to wait for the PG&E inspection/meter swap (for Net Metering/Time of Use). This was a couple of weeks. Then I had to call to change to the EV-A rate, and when I called, I got the '1-2 billing cycles' line from the PG&E CSR. I'm sure it takes a couple of keystrokes at their computer, but why rush to lose cash flow...
