Powerwall Woes

Hey All,

So when I first got into contract with my installer they had told me that there were Powerwalls available in their warehouse to be installed.

Since I was under the impression I could get them installed sooner, I signed.

However, as many here know, their installed price was much higher than Tesla. Even now, after the price increases on Tesla's side it's more expensive.

2 Powerwalls:
$19,500 vs $15,500 (worst case from Tesla's calculator)

A difference of $4k

Now, I'm in confirmed SGIP step 2 with my current installed and that rebate is $9,280.

If I cancel and go with Tesla I might be lucky to get in step 4 or 5 to which the math breaks down as such:

Current (step 2 rebate) $9,280
Total cost after rebate = $19,500 - $9,280 = $10,220

Tesla (step 4 rebate) $6,960
Total cost after rebate = $15,500 - $6,960 = $8,540 (Savings of $1,680)

Tesla (step 5 rebate) $5,800
Total cost after rebate = $15,500 - $5,800 = $9,700 (Savings of $520)

Alternatively I could apply to be a developer myself and potentially get into SCE step 3, but that seems like a fair amount of work and it's dicey on whether it'll pan out or not.

So what would TMC do?

Cancel the order or keep going forward?

Does Tesla's price include installation, wiring back-up panel etc?

Do you already have Solar?

Solar is getting put in on Monday, so "yes"

In terms of the pricing, I just went off their calculator:

Ah, ok. TE quoted me roughly $7900 for a single PW2 installed, but they didn't actually have inventory. I was going to suggest going with my solar provider who has inventory, but prioritizes the Powerwall installation if done with a solar install.

Expect an upper limit for Tesla at $17925.
1. Powerwall increased from $5500 to $5900
2. Gateway same.
3. Sales tax for above. Permits $150.
4. $800 install. Additional powerwall increased from $100 to $200
5. Main panel upgrade increase from $2500 to $3600

Guaranteed in contract SGIP rebate vs. program risks. It's a tough decision. I did the homeowner developer route. Even though secured the reservation for funds, program risk is double.

Too bad I can't sell my SGIP reservation, if I didn't sink too much time & energy into it, I would gladly walk away.
