I had to call Tesla for my family member because they did not get the referral bonus. They eventually got the referral bonus few weeks after.

I thought the process would be better. I simply told them the concern regarding the referral and they fixed it.

Our Tesla Solar + Powerwall was incredibly clean and efficient. We lucked out living in a city where they have a unionized staff of 29 building inspectors that do their job extremely well and efficiently. We've had it for 9 months and zero issues. I love charging my M3 with my own stored electrons at night. W/O PW you still have to pay to charge at night. And the 26% fed tax credit make sit a no-brainer. Up here having resilience against PGE is highly value added as well, so it was likely the highest value investment I could have made for my property.

Tesla still being around doesn't mean Tesla Solar will still be around. Solar has been a pretty bad line of business for them generally. It's only profitable because of powerwall sales, which is why they switched to requiring both. They only changed course on that because powerwall use chips that they need for cars right now. I would bet that it's not long before Tesla spins off energy generation and focuses only on storage.

CA has Net Metering.  What's the benefit of a PW in this situation?

Use the stored energy in battery to run stuff from 4-9pm while using the regular grid during the cheaper times.

Pretty sure OCtoSV is up north and they may have blackouts/brownouts so a powerwall makes sense.  Down here we don't get hit with that much and between me and Cares, the #'s don't make sense to get a powerwall unless you have OCtoSV's use case or something else you need to store power for, growing weed, mining etherium/bitcoin, whatever it might be.

So can you set the PW to store electricity only during off peak time and then during peak time, sell the energy to the grid at the higher rate?

I never use the grid - Solar during the day, and PW take over as usage becomes > solar generation. During the day I sent most of the Solar back to the grid once hte PW is regenerated. My first PGE "true-up" is next Feb, and I think if I read the arcane 10 page statement correctly I am due ~$500 so far.

yes

there are two ways to "sell" energy back to the grid in CA. one way is you get storage credits with your provider that are used to deduct against your metered usage. so if you "sell" energy during peak times, and use grid supply during non peak times, you come out ahead.

at end of year, any excess credits are liquidated at wholesale prices. so if you rely entirely on solar and PW and never use your banked credits you are getting a lower rate for your excess production. but you may value the energy independence more highly.

Apparently batteries can be run on a timer.
I do not have batteries for my solar, but was told this by the salesman.
I took my batteries budget and added more panels.


Why?....batteries degrade faster than solar panels.
I think by year 10 you are down to 70% charge....but who knows....

storage is so expensive per kwh that I really doubt it makes economic sense to get batteries just to arbitrage peak/off peak rates especially since the sun is out during much of the peak time.

it's more for people who want to be self sufficient and have protection during outages

Also to fix energy costs. Avg PGE bill is almost $200 and rising rapidly. Couple that with stressed generation and transmission capability and fire related blackouts (even though my neighborhood has buried utilities) and the 26% federal subsidy and it just made too much sense.
