Sorry if there are posts about this already, but I'm not really sure if there's anything up to date on TOU rates for new Powerwall/Solar installs in the PG&E coverage area.
My understanding is that new PTO's can only choose from these 3 options:
Is there consensus that either EV-B is better/worse than EV2-A?
The shoulder and peak times for EV-B seem absurd... basically lasting 7am to 11pm. But that also means solar generation is worth a bit more since anything during sun-up would give a better generation credit than the off-peak.
I feel like in a perfect world, someone with PV + ESS would sign up for EV-B then find a way to charge their Powerwalls to Maximum between 11pm and 7am (something PG&E encourages!). This way when the sun comes up, the solar is just going back to PG&E at either the shoulder or peak rates. Then when the sun sets, the homeowner just burns through their Powerwalls between dusk and 11pm. Then rinse and repeat.
But since Tesla doesn't let you charge the Powerwalls with off-peak energy, it seems like an impossible task to effectively manage a day/night cycle under EV-B without risking getting blown up by the peak and shoulder rates after sunset.
Making sense of the rates.
FWIW I don't actually own an EV to charge overnight. But it doesn't look like there's much difference between the two plans if the EV is always charged with off-peak energy.
