Powerwall before PV?

[YYZ QQ]

Now that Powerwall OS2 is almost here (yeah I know.... almost) how difficult would it be to add PV at a later date and use the Powerwall to do TOU shifting until I decide if/when I will get PV?

Not difficult. That’s what I have been doing since Sept 2017. I have two Powerwall and no PV.

I am in same situation,
It should be fine if you got approval from PG&E for Powerwall, otherwise , They will ask to retract the Powerwall application and submit PV & Powerwall together. Its because , PG&E doesnt allow 2 applications at the same time. So they have to combine Powerwall & PV and submit

I am in Canada (outside Toronto) so PG&E's policies wouldn't apply up here. At least I hope they wouldn't.

How hard would it be to add PV afterwards?

From my recent PV installation experience, and I'm still pre-PowerWall, getting the PowerWall install first, or simultaneously, is much less hassle overall for wiring and installation, IMO.

You'll:

• get any power-panel upgrade first.
• get the Tesla Gateway mounted next to it immediately.
• all the necessary wiring/conduits is set, done.
• PV would just be an extra feeder breaker or panel afterwards.

If you did PV installation first, they:

• may have to redo the power-panel.
• mount the PV connections.
• upon PW installation, rip out all of the PV power-panel changes.
  • possibly pull all of the breakers out of PV upgraded power-panel to put in a sub-panel behind the Tesla Gateway (leaving an empty, wasted power-panel upgrade) for whole-home backup.
• then the regular PW installation.
