The article says install cost starts at $13K AUD ($9210 USD). That's $1316/KWh USD installed. At this price, it will take 27.5 years and 7147 cycles (at 70% DOD) to cost break even time shifting off-peak electricity with FP&L TOU plan. This is crazy expensive. Edit: Seems like that price may include solar panels too, making above calculation wrong.

According to this article it says an 8 year payback(without taking into account carbon tax rebates)
The Tesla Powerwall is finally rolling out. First stop: Australia
According to Pfitzner's calculations, for his family, there should be a return on investment in less than eight years. "If [power] prices go up, or in the likely scenario we get a carbon tax back, it's going to be good."

First Tesla Powerwall operational in Australia under Energex solar battery trial: pv-magazine
Anyone hear of any power wall deliveries in other countries, like maybe the USA?

I haven't heard of any Powerwall installations in the US. I am in California and really want one this year. I made an email "reservation" the day after the Tesla Energy launch last year but have heard nothing since from Tesla.

I have an old EV friend who lives in the North Bay San Francisco area. He has been hired by Tesla to be a Powerwall Installer. As far as I know, he's still training. I had my reservation in early, also.
I believe Australia has a feed-in tariff system that strongly encourages self-consumption. In other words, you pay retail for everything you pull from the grid but get much less credit for anything you push into the grid. This is a good reason to use battery.
Having grown up in Australia and moving to SoCal (for a Tesla, I might add) a couple of years ago, I can definitely confirm that Solar Power is very popular there. Both my (rented out) and my parents' houses have a 5kW system on the roof, I have an SMA Sunnyboy with SunPower panels, and my parents have a Fronius Inverter with Renesola panels.
Yes, this is correct. So when they started, they used to have a feed-in tariff of about 60c per kWh. There is a person in Canberra that took out a mortgage in order to buy about 30kW worth of system, so that after his loan was paid off, he'd be making solid money every year. (There was no reasonable limit on how much solar you could put on the roof).
Yes, they got rid of that pretty quick, (they were grandfathered until 2020 iirc). I remember shopping around and most power companies would give you between 4-7 cents per kWh as a feed-in tariff, while still charging 19c for offpeak and 38c for peak.
So apart from maybe California, Aussie Power is extremely expensive, and there is huge dependence on Coal Power plants. Hence the push to sell powerwalls there (and in other countries) first.
UK installers are taking Powerwall pre-orders now and claim installations can happen in March, which came out of the blue. At £6k and assuming you have a Solaredge inverter already it is not cheap, but I know quite a few who will order - if you can afford to and want to add to the momentum and economies of scale then fine!
