    The new Powerwall 2.0 basically double both power output (kw), and capacity (kwh) of the previous version of Powerwall. AND, it now include an inverter (DC to AC conversion) fully integrated inside the Powerwall 2.0. One of them costs $5500 USD.

    Need an option for "my state has net metering and no time-of-use rates for residential, so this battery does nothing for me"

    I already maxed out the number of choices (10 max). And these poll can't be edited once it is posted.

    Yeah. Although I might consider buying one as a time-shifting mechanism to deal with parts of the year with little sunshine. I'm not sure time-shifting is allowed under PGE rules though.

    what do you mean by time-shifting is not "allowed"? You can do it once you have solar and Powerwall installed. You can technically do it. But whether PGE discourage you from doing it through financial dis-incentive is another story I bet.

    You didn't really have an option that fit me.
    Solar for 10 years already. Paid off now or very soon.
    My usage is right about even what I produce over the year to what I consume.
    My utility will pay me for any extra power.
    We only have power outages about once a year for 2 hours.

    My question is really why??? So I went with too expensive.

    Time shifting is one thing but that will go away over time as California has a lot of solar panels.

    What about time shifting over the year! Elon keeps showing that graph of during one day, but the amount of energy you generate is very small during the winter.

    this poll is specifically for Powerwall. Not solar roof (I have another thread for that).

    Since you said that you already got solar, maybe you should add a Powerwall just to do load-shifting and as a back-up? It is a very logically step for most people who already own solar.

    load-shifting to allow you to fully rely on battery in winter time will be super expensive. You need probably like a two million dollar system, so that you get enough solar energy stored in summer, and rely on batteries (and partially from grid) in winter.

    I don't think any companies in the world can solve this load-shifting from summer to winter problem. There are less sun in winter, just no way around it unless you are willing to get a 2 million dollar solar/battery system that is similar in scale to your local power utility sub-station.

    nope. ran the #s on the first powerwall. Would only recoup costs in 20 years or so as the differences were so minimal. And that was not considering time value of money or changes in the rates.

    does your math improve with Powerwall 2.0?

    For those who are interested in, you can see the specs of the old Powerwall 1 at 5:02 of this video. The new one is much better in every way!

    It makes me wonder if there will be a cheaper version of Powerwall 2.0 that have the inverter excluded. That will help with the cost side of the equation.

    Anyone suggesting a battery to store summer energy for use in winter needs some serious help with the math.

    I live in a somewhat rural area with occasional power outages, and I'm on well water. I'm getting it to bridge the gap between power outages and keep our water going, among other household appliances and conveniences.

    Except for aesthetics... I actually like the design of Powerwall 1...

    Functionally, 2 is better than 1, however.

    Would love to get an Excel calculator going to plug in my off peak rates to see how quickly this thing will pay itself off!

    Have solar already here in AZ. Would like powerwall. My system currently disconnects when there's no current detected from the grid.

    So I'm wondering if I can even use this as a backup?

    Does Tesla change the system slightly to allow for this? Or is this a municipality/code regulation
