*Price includes GST. Does not include delivery, installation, or other costs and fees. Final price will be provided by a Certified Installer.

Keep in mind this price is before installation and delivery.

That said, in the US the PowerWall (PW) 2 and PW3 have been the same price. Yet the PW3 includes an inbuilt inverter.

PW3 has 11.5kW of continuous power and 13.5KWh of capacity.

Once the NSW government battery rebate hits on 01.11.24 the price of these could drop to around $11k installed, which seems to be reasonable since most people are pretty much giving away their solar to the grid now.

The other thing to keep in mind is that you can recharge from the grid. So if you use OVO you can recharge from 11am - 2pm for free (though that’s when you solar will be pumping) and you can also recharge the PW with offpeak power from 12am - 5pm.

The downside of the PW is that it’s not modular, unlike the other two which are highly rated by Solar Quotes, the SolarGrow and BYD home battery systems. Where you can add a few KWh of storage easily and (potentially) make use of falling battery prices.

      Sure, off the grid for 3-6 hours on a good day :-) Most home usage is outside the solar window - at least here in Victroria, without batteries most of what you generate is going back into the grid for tiny credits.

        31kw should last a few days depending on usage (potentially more depending on requirements)
        The biggest issue is having the quantity solar panels to replenish 31kw in batteries.

              @DannyBoy: you would need at least 20 solar panels to get a consistent charge to the battery, as well as a windmill or 2 for day and night charging.

                Given that you could get a 40 panel @ 250W each - 10KW array…. for much less than the price of 1 battery…. your point doesn't seem very valid.
                If you're somewhere with less than 3 sunlight hours a day… you're in a strange place.

          The best part, though, about having 31kwh of battery capacity is so that you can soak up excess power others are producing during the summer (WHILE ALSO GETTING PAID FOR IT), then just let ‘er rip during the night, then wake up and soak the electricity again.

    • Gratt on 05/08/2024 - 08:45

      There is something intrinsically wrong with the pricing of solar batteries. You can buy a whole BYD car with a 60Kwh battery for under $50,000. Why are house batteries so expensive? I wonder if a smaller house battery would work better with a generator input (hybrid inverter) and using the cars vehicle to load capabilities to feedback into the house system. Even if you only feed into your smaller house battery it would give an additional 24KWh over a 12 hour period. It would have the advantage of having an economical to run car plus if you do run short of power in a major outage you can take the car somewhere and recharge it, effectively ferrying the power back to your house.

      • kungfuman on 05/08/2024 - 09:08

        car batteries are inferior to house batteries they cost more because they have to power a house. a car battery only needs to power a car which is alot less power than what a house produces, the output would be much higher and for much longer periods than a car would.

        • Elijha on 05/08/2024 - 13:29

          yet they keep talking about a feature (V2H) where you plug you car into your house to run it.

          • kungfuman on 05/08/2024 - 16:17

            @Elijha: yeah I know the feature its not designed to run for days its more of something that lasts you a few hours in a black out. or a day at the most. You put incredible strain on a car battery that is not designed to charge a house for days or weeks. Its good for temp use, but I would never use it for anything more than that.

        • Nom on 05/08/2024 - 16:18

          car batteries are inferior to house batteries

          The opposite is true.

          EV Car batteries have advanced climate systems to heat AND cool the battery to the optimal temperature at all times. Most home batteries don't do this.

          they cost more because they have to power a house. a car battery only needs to power a car which is alot less power than what a house produces,

          This is completely backwards.

          A battery in an electric car is capable of outputting 150KW or more - this is way way more than your house can ever consume. Even if you turn on your 5KW Oven, your 2KW Kettle, and your 10KW aircon, you're only drawing 17KW….

          the output would be much higher and for much longer periods than a car would.

          No.

          The 60KW battery in a basic BYD car can indeed output power for over four times as long as a 13KW Powerwall.

          A KW is a KW…

            @Ellllllys: I have a solar system and a big fan of it. But, tbh, with plans like OVO with 3 free hours, it is possible to schedule most of electrical "heavy lifting" to those hours - Water heating, charging EV, washing, dishwashing, pool pump. It will replace any solar system to 90% (especially with 3c FIT).

  • Dishcloth on 04/08/2024 - 15:34
    +22

    For those wanting to do the sums:

    PW2 has 13.5kWh of capacity. If you were to able to recharge these completely during the day and drain them completely in the afternoon/night, this is worth the following at today's rates:

    At $0.31/kWh this is worth about $4.20/day, $130/month or $1500/yr. This unit is $12K + installation. Say another $3K install. So $15K total = 10 year payback. What is the warranty? 10 years.

    Now incorporate low sunlight days into the mix - payback extending 12+ years?

    If you have unreliable power having a battery backup might be useful.

    If your power is reliable, this thing isn't paying itself off any time soon - if it lasts.

    Once this gets to a 5 year payback, then I'll be interested.

    • BarrytheBargain on 04/08/2024 - 15:47

      That seems about right based upon my research, 8-10% is the best case return for most people (considering also battery will degrade, so will solar, potential retailer rate changes), does not quite sound like a good value proposition and would prefer the zero risk returns in an offset account or if you don't have a mortgage and don't mind the risk, shares.

    • timochy on 04/08/2024 - 16:11

      If you do your sums on just the battery alone, you are probably about right.
      I do my sums on the solar + battery install together.
      For us, 14k was the install price for 13.3kw solar and 13kwh battery just under 3yrs ago
      Its almost 3yrs now and we’ve saved approx 12.5k
      So for us, our pay back period for solar and battery is just over 3yrs

        • BarrytheBargain on 05/08/2024 - 07:13

          Exactly, solar can easily be 25% payback but adding a battery makes payback 10+ years so doesn't make sense economically in my opinion. If you add both at the same time, solar does most of the heavy lifting for the payback so you may as well just get solar only.

        your calculation is flawed because you get massive rebate from SA government when they were desperate to save the grid from collapse. People around that time can get solar and battery similar spec installed for even less than half that cost. Those rebate is pretty much gone now however.

      One of my friends has one. He mentioned something I wasn't aware of.. Which is his "daily capacity" is more like a factor of 1.6 according to the software. So closer to getting 21kw out of his 13kw system per day.

      Because it charges and discharges throughout the day. Like when a cloud comes over it uses battery for that half hour and then sun comes out and it goes back to charging it again or if he is just "balancing along" and turns on the oven it'll consume from battery and then flip back to solar and charge again rather than taking the excess from the grid. By night time it's fully charged and he can use the remainder.

      With economy of scale it already gets quite close to 5 years payback. I'm talking about the massive batteries that get added to our grids. Prices for those have plummeted to around AUD 500-600/kWh, including all the other work (HV transformers, etc). Mind you, that's for the GWh size range.

      Unlike solar, where making use of all available roof space totally makes sense, batteries are fairly compact, and building them on a utility scale is a lot more efficient.

      If only we could trust the people who run them not to rip us off…

          I guess it depends on the household. Ours is definitely expensive. That said we’re trying to be as efficient as possible but sometimes you just wanna have a warm house in winter and a cool house in summer…

            @Ellllllys: What does it cost to borrow the money to buy one of these? I can't imagine any young family owns their own house outright so it'll usually mean not paying savings into the mortgage and paying more interest than they need to.

        If you do that, then why would you go on a TOU tariff? Stick to the basic rate.

        • Ellllllys on 04/08/2024 - 15:53

          No choice when you have a smart meter 😔

            @Ellllllys: What state are you in? I got switched to tou when I got solar but was able to switch back when I asked about it.
            I'm in vic, with smart meter and solar.

            @Ellllllys: then you haven't done your research hard enough, you can choose to go with other tariff type not just TOU, and can even select retailer best suit your need because not everyone follow distributor pricing guideline.

      I guess some have assumed Albo and his cronies will be in power for the next 2 or 3 terms, and the anticipated energy price rise in that period (while Aussie culture and society falls apart)

        Would you like me to send you 10 years of pain killers…. while you wait for button head to be ready to build a nuclear reactor in your backyard?

          Quick, tell our Olympians to get out of France, that place is full of nukes!

            @BlahBlahBlaah: I was talking more about the economy of nuclear power than the radioactive risk…. but yep, there's that too.
            Although….
            As of early September 2022, 32 of France's 56 nuclear reactors were shut down due to maintenance or technical problems.[57][58] In 2022, Europe's driest summer in 500 years had serious consequences for power plant cooling systems, as the drought reduced the amount of river water available for cooling
            I wonder why France wishes to actively reduce their electricity produced by nuclear power by about 20%.

            But you're probably right… dutton is so smart that he doesn't need to do any of the research and planning and costings that private companies do… he's so smart that he can say he's going to go lefty and create state owned nuclear reactors of unknown design, unknown cost, and unknown profitability. You can see the halo over his dome if you look carefully enough.

    Wait for V2G/V2H vehicle. In SA you can hook up your nissan leaf and use it as a battery.

      Two tesla Y family household with V2H+solar+off-peak 8c charging 👌

        What is your set up for v2h?

          This doesn’t exist in Australia yet outside of some very specific test cases.

        • Kammi on 04/08/2024 - 20:56

          Hypothetical setup!

          So electricity companies would make more off connection then usage charges and I don't think they like this so any barriers that are up i think won't come down for years to progress v2h.
