Tesla panels and total price after installation is too high to be competitive- only the Powerwall enthusiasts buy panels+powerwalls from tesla. Other panels are so cheap these days and EG4 makes excellent power storage options.

Last year I asked them for a Powerwall quote and was told that I can't get powerwall without their solar panels

You can do this if you use an approved third party installer. I just installed a large solar array with non-Tesla panels but using two of the latest Powerwalls as inverter and storage

Powerwalls have been a huge disappointment for me so far. It gets pretty cold where we live but the Powerwalls are installed in a somewhat insulated garage. However in winter it gets cold enough in there that they need to use their own power to keep themselves warm, so they drain themselves that way in just a few days if there's no solar charging. Similarly, when the solar generation is high they need to cool themselves and that uses power. Our utility doesn't allow grid charging of storage. So all together I have relatively hope we'd actually have much backup power in an outage.

Why use a Powerwall if you could use a better and cheaper inverter battery combination? Just because the app is beautiful?

> Just because the app is beautiful?

Yes, that's the only possibility right?

In case you wanted a serious answer and not just an internet reaction: our utility offered substantial rebates on Powerwalls specifically.

I’d be curious to hear how other providers compare in this scenario

Maybe add some sun-facing windows to said garage? Insulation alone won't keep a space without a heat source warm...

Interestingly enough, Powerwall is the only product I know and heard of, which can do grid disconnect and reconnect out of the box.

Unfortunate for this particular product (i do not like tesla anymore), i also never heard anything about it after that one Musk presentation infront of a house with tesla roof.

But if your ecosystem is Tesla (before Musk), the synergy would definitly be very nice.

'Just because' lucky enough some people do not mind investing money into beauty.

That's a great idea - I may look into that.
