How may days/weeks did it take to get Dominion to inspect and grant PTO?
I was given the same 2-3 week estimate as you by my Tesla install PM.
Here's how my timeline actually went:
Dec. 4: the PV/electrical portions of my roof were completed and passed county electrical inspection
Dec. 5: Tesla sent one text stating my "system has passed inspection" and a second text stating "your invoice is now available".
After receiving the invoice, I paid half the balance via credit card (because of limits on the card).
Dec. 8: Tesla sent a third text stating "we recently submitted your project for utility approval".
Dec. 9: Roofers finished the non-PV portions of my roof.
Dec. 15: I paid the remainder of my balance via credit card.
Dec. 16: Dominion Energy upgraded my meter.
Dec. 17: Dominion emailed me "Authorization to Interconnect" and Tesla sent a final text stating "you are ready to power on your Tesla system".
My Tesla install PM told me that the timing of payment would not affect PTO. I'm still not sure whether that was correct since everything finalized as soon as I completed payment. Maybe just a coincidence? My payment was drawn out because I wanted to use a single credit card that had a higher reward amount but a lower maximum.
