      How much cost and capacity pls

      • +1

        I think it is $15,495 and after 5 years it is $13,995. Based on this post: https://www.ozbargain.com.au/node/789897

        • +10

          Fark, they've gone up! They were under $10k installed when they first came out, I didn't realise they've been going up vs solar which is coming down.

          • +3

            @noisymime: Well, it went up because our AUD went down. A lot of Tesla Powerwall are imports so naturally, it would cost more as our AUD keeps taking a beating and then there's inflation…

            • +25

              @Jetkuma: AUD to USD was around 0.72 in 2016 when the PW launched vs the 0.65 today. Sure that's dropped a bit, but it's not the 30-40% that the PW price has increased by since then. Yeah inflation is in there too, but compared to solar, it's going the opposite direction.

              • @noisymime: Haven’t the government rebates gone down as well over the years? This would have also affected the as installed price.

                • @Tazzaaa: Aha mate there isn't even a battery rebate in Qld. Some states and territories have their own schemes but there is no overarching federal scheme.

            • +1

              @Jetkuma: also the cost of the raw components to manufacture has skyrocketed

          • +1

            @noisymime: Solar def isn't coming down. 2 years ago a 6.6kw Solaredge system with Trina? panels was 8.5k. Now it's 11.5k…

            • @milobob: You're right about solar systems going up as STC rebates also coming down. Got quotes recently for a 10kw Solaredge system with trina for under $10k though so there are good deals still to be had.

              • @uetecu: Can you tell me which company? I have a quote for 10kw Canadian Solar and Sungrow for $12k

                • @kurdoxan: Solaray we’re doing EOFY sales at the time but I’m sure you can talk them round 😉

            • +2

              @milobob: Sure prices have gone up the last 2 years, but they're still around half the $/w that they were when the PW2 launched in Aus back in 2016. So panels have dropped by around 50% and the PW2 has gone up by about 40% in those 7 years.

          • +7

            @noisymime: I was under the assumption they would be cost effective by now but mmm no thank you!

            • @Bdawg: energy costs have gone up massively since they were introduced too

              • @DryScissors:

                energy costs have gone up massively since they were introduced too

                And do you see the connection there?
                When the hard push for renewables were being made we said they would cost more and would drive up the cost of living, but some people just don't want to listen…

          • @noisymime: As your solar goes down they go up. Makes it even.

          • +1

            @noisymime: We got a Powerwall 2 a couple of years ago and likewise, under $10k installed, but there were state govt grants/subsidies in place then, now nothing, at least not here in SA, plus the batteries themselves have apparently gone up.

            With FITs dropping each year, it's almost necessary to have a battery to really reap the rewards of solar, otherwise you're selling it back to the power company's at 10 cents per kWh (or some offer you the going rate for the first 14kWh exported and 5 cents of less for everything above that), and then you're buying it back from them for almost 40 cents per kWh.

          • +2

            @noisymime: I wouldn't worry too much. So it used to take 10 years to get your money back instead of 14 years. Either way, the warranty will run out before you break even which means that you'll end up losing. The winning technology is when electric cars can act as a battery when parked at home, a dedicated battery will be made virtually obsolete for normal households.

        • +7
          • @8at8: Thanks for that pricing history…. interesting (and sod all to do with exchange rates)

            Great technical content though….stuff like… the battery has a positive cathode and a negative anode…. if it didn't, it wouldn't be a forking battery!

            Interesting in the pros and cons….they make no mention that tesla's cobalt cathode technology tends to be far more reactive (a soothing word for fiery) than LiFePO4… (lithium iron)

        • +5

          Too expensive imo… My electric bill on winter is around $100 and summer $30-40 or so. Thats roughly about $800 per year. To cover for the roi alone, it'll take me about 18 years which is double their warranty period

          • @kaleidoscope: That is why power companies are paying you for VPP

              • @kaleidoscope: VPP is when you sell back your power (from solar presumably) back to the grid / energy provider and hence making some money on top of saving from your bill.

          • +2

            @kaleidoscope: Winter bill of $100, per month? I can't get $100 per quarter purely based on the daily supply charge. I get about $350 a quarter regardless of season. 1-3 person household depending on circumstances.

          • @kaleidoscope: Are you burning craploads of gas… or are you like me, doing wise things with off-grid solar augmenting use? Or are you living in the 70s (1870s)

            • @rooster7777: mix of everything I guess. gas ducted heating with multi zones and time based programming and oodies 💪.

    tempting but the powerwall 3 should be out soon?

    • Do you know when (ballpark)?

      • +1

        no idea but the powerwall 2 has been out for a long time with several updated versions.

        Rarely discounted so im guessing the new one is going to be just around the corner.

      • +1

        I haven't read much, but there's some talk of later this year.

        That's likely the US market though. Our rules/grid is very different so I doubt it'll be available here at the same time (but could be wrong, SA was a huge market for them initially so we get more visibility than most small countries)

    • Any rumours on what benefits the power wall 3 will have over the power wall 2?

      • Rumours suggested it being LFP?
        If so- realignment of performance/price ratio potentially on the cards.

        • +4

          Thanks, just had to look that up. Seems like benefits of lfp batteries are improved safety (thermal runaway), improved longevity (cycles and calendar life), reduced ethical concerns (re absence of cobalt and associated mining concerns), reduced cost (due to absence of cobalt and abundance of iron).

          However possible drawback of reduced energy density.

          Is that interpretation correct? Have I missed anything. If correct, seems like the benefits are worth waiting for.

          • +3

            @Worf: Good summary. The reduced density is not a big deal for fixed residential and commercial installations. They would likely be a bit more bulky and heavy, but that's not a big deal since it only has to be placed once. LFP is also supposed to be a bit cheaper to manufacture.

            Tesla have already been using LFP batteries in some vehicles for a couple of years - the Model 3 & Model Y RWD models have them, but Long Range and Performance models still have the older style lithium batteries for lower weight and higher discharge rates.

            • @klaw81: In addition, LFP can charge and discharge to 100% which means you get a 20% boost in usable capacity, even if the total capacity remains the same.

          • @Worf: btw, why if bulk is a thing, are these placed on the wall and not in the roof cavity (away from sun too?)

            • @furyou: Unsure… but I’d say two reasons.
              Firstly, Ideal battery temp is warm (15 to 35 degrees c). But I read somewhere that outside of the ideal range, they still work from -20 to 60 degrees c. Australian roofs would run hot / above ideal range.

              Secondly, Pain in the but. Heavy, bulky and inconvenient to put into roof cavity. And if there’s a service issue, it’ll be much easier to access on a wall.

              I’m no battery guy, and this is just a guess. Maybe someone with more knowledge can explain.

  • +1

    Would also like to know the cost and capacity. Thanks.

    • A single Powerwall 2 (current model) has a capacity of 13.2kWh and a maximum discharge rate of 5kW.
      Cost is allegedly $13k + installation.

      • +13

        I'd rather wait until V2H cars are more common, same price per kWh but you get a free car with it (MG4 is $40k with a 51kWh battery)

        It's annoying, because many cars have had the ability to do it for ages (every Nissan Leaf since 2013 has had the ability) but the regulatory approval is very slow.

        • You'll be waiting for a long time. Home batteries take a lot more pain than car batteries.

          • +1

            @Penalty boxer: The tech exists and is in use though, it's just the certification process that's taking a long time.

            And what makes you say they take more pain? A Powerwall doesn't charge or discharge at anywhere near the rate of a car battery. If I can charge and dump power out of my car at over 100kW I'm sure it can handle sending 5kW to my house easily enough.

          • +2

            @Penalty boxer: How do you work that out? The home batteries have a harder life? I'd think the opposite is true.

        • But unless you leave your car at home all day or work on nightshift (charging on solar), wouldn't you be filling your car with grid power anyway?

          Also, wouldn't you need to purchase a bidirectional charger to manage your home power as well, surely they wouldn't come cheap since it has to manage your houses load from vehicle and the grid. It would probably be a few thousand for that alone.

          • +2

            @Doogan: I WFH, so charging is easy. Plus many companies have cheap EV plans - https://www.powershop.com.au/electric-vehicle-tariff/. If I worked 9-5 in an office though I'd let the car power the house from 5-9pm then charge it up. I have about a 12c difference per kwh on peak vs off-peak. A battery would be beneficial though in that case with solar it could soak up during the day.

            I would have thought a hybrid inverter would deal with it, it's needed anyway with battery/solar and handles the load from grid and solar. Hybrid ones handle a battery too and are needed with a powerwall anyway. But it's hard to find pricing, the US company that sells one for the Leaf only sells to corporate/fleet and I couldn't find pricing for it (the Fermata FE-15).

            edit: Maybe it is pretty pricey, there's a company in the US that makes an inverter that handles solar + charging + V2H, it's $US5K - https://www.dcbel.energy/r16/ - a lot more than pretty much any hybrid inverter I've seen.

            • @freefall101: This has an interesting look at v2g and also mentions about the one available charger in Aus that works with the Nissan leaf: https://www.solarquotes.com.au/blog/australias-v2g-future/

            • @freefall101: I thought that might be the case, one can hope they will come down in price. It is quite a similar issue to the current house battery systems. The batteries themselves are not terribly expensive, but rather how they are packaged with the system that manages grid load. Sometimes it seems like having a seperate system running completely off grid might be the better option in your home. But I don’t know the regulatory hurdles in Australia.
              I find this blokes YouTube interesting for it. https://youtu.be/CVrgZPQYQYE

        • regulatory approval is very slow

          Regulators are on the side of corporate interests. Why would they want you to buy once when they can make you buy twice?

        • Until you find in a few years that all those extra charge/ discharge cycles for powering your residence have left you with an electric vehicle range of 20 km… at which point you may be thinking…why oh why did I do that!

          • @rooster7777: Unlikely with Lithium Iron Phosphate, which cars (but not the MG4) are moving to. They won't lose 95% capacity.

              • @TheCandyMan2020: Same. That’s a realistic figure for quite a lot of people.

                • @Jinster: I don't think that's realistic at all. My winter bill is $1200 (Rounded up 4 people in the house) for the quarter and I have a pool. There is also a comparison of people in my area with pools and I'm about average.

                  You guys are using too much heating or have like 10 people in the house.

              • @TheCandyMan2020: Central heating?

              • @TheCandyMan2020: That is insane. My last bill up to mid June is under $400. 5 people, 4 bedrooms.

              • @TheCandyMan2020: This sounds way too high. Is the heater on 24/7?

    • +10

      It's different for everyone. Even if you had the perfect math, you need to assume perfect foresight (how much the sun will shine in winter to charge the battery, how many cloudy weeks, etc)

      In general, batteries have a poor ROI right now - even if you do something like Amber SmartShift. Solar panels have a better ROI.

      • You don't even need solar to make money, sign up for time of use tariff and you can essentially get all day at off peak if usage is not excessively high.

        • Then the ROI is even worse than charging the battery with PV.

          And the ROI on PV is much higher than a home battery so it doesn't make much sense to get the battery first.

          • @coxymla: I think you'll find that the ROI assumptions have changed since ROI on solar is based on the FIT return/credit.

            If you plug your latest Tariff rates into a solar calculator like https://www.photonik.solar/savings-calculator , and adjust the sliders for your daily usage, not your current bills, e.g. I get a recommend 10kw solar (which I bought in 2021 for ~$9k) based on my daily average consumption (which you can get from a recent bill) of 18-25kw.

            There's even a basic 'roof design' to map out how many solar panels can fit on your roof, sic.

            Once I change up the tariffs, ROI for solar is getting to 5 years. If I add the PW2, it comes to 6.5 years, which isn't a number I expected to see.

            My system has actually saved $3.5k in 2 years, so it's within a 4 year repayment period with a decent FIT… but that's because I fed usage/billing data into Wattever's Bill comparison, which are more useful when you have solar. As Wattever's comparison can show what the affect of battery, additional solar, removing solar, adding an EV, removing an EV would be on the hypothetical yearly, monthly, or current billing period.

            Even if I tweak the numbers, switch to flat-rate, change the FIT, use a better plan, sic. It's just a whole different set of comparisons to 2021 when I had solar installed due to the drop in FIT and the rise in prices. In my example, a Powerwall 2 sized 13.5kw battery cuts my bills by $4k a year with ToU, and 7.5 years ~$3.5k yearly with Flat rate, which makes the payback period 8 years, not counting VPP discounts/rebates/deals.

            Solar installs that used to have 6 years ROI, have shrunk to 3 years, then back to 5 years due to the drop in FIT, and the rise in Tariff rates.

            Batteries on the other hand, have dropped from 12-18 years to 6-9 years, within their warranty periods, because a Solar bill that used to be $120 credit and $200 usage, is now $50 credit and $350 usage. YMMV.

            If you can save ~$2k a year in bills, $5/day, Storage can work. But it also relies on energy prices continuing to rise. YMMV. That's not accounting for Financing, BNPLs, VPPs or special two-way tariff plans that rely on Market Pricing events to cash-in on Peak rate surges where you can collect $50/day.

            Battery ROI is based more on consumption patterns, and the FIT to Tariff ratios. The ROI used to be ~15 to 20 years because the ratio was 1:2 to 1:3,

            eg 8c-15-20c/kWh FIT vs 21-26c/kWh Flat rate.

            Now it's 55-70c Peak, and some DNSPs are considering variable Time of Use solar export/curtailing, daily caps of FIT export, Demand rates, making Peak for weekends and later in the evenings until 9pm or 10pm, or removing Shoulder rates et al. So, by 2023, recent DNSP and Market rate changes, a few power station closures, Natural Gas price jumps, and a few new wars, FIT has dropped to 4c-8c, Flat-rate Tariffs have jumped to 35-45c, Peak is occasionally 60-70c, and off-peak has also jumped above 20-26c, where it used to be 12-18c.

            The old ratio of 1:3 is more like 1:10, so Solar has lost some of the ROI payback period as a result.

            While the ROI on solar alone is ~3-4 years on a 6kw to 10kw system, the old metrics are kind of shot, because the old FIT assurances of steady growth, steady price increases along GDP/growth jumps, hasn't happened. We just get 10% to 25% bumps instead.

            Possibly because the DNSP has made deregulation kind of mean i.e. AEMO and Market pricing jumping erratically has forced DNSPs and Retailers to cut corners or block customers, but because of the deregulation, and the price comparison sites … They are wedged between manipulating pricing or having 'variable rates' like Demand pricing, which can't be seen in the comparisons, same with Solar rates not being included, or lowering their daily charge so they get to the top of the comparison pages, means retailers are afraid of raising prices against their tight-knit competition, and the restrictions of how the EME website works.

    • +5

      It's not worth it. We have a PW2 (came with the build so it was cheaper to keep it then get a mesely $5k credit for it).

      In victoria, the power it stores (which is minimal in winter) is gone within the hour (since it so cold, dark and cloudy of the time in winter). Summer though it's great. We don't use any power from the grid at all for about 3-4months a year.

      • +4

        You can still charge it off the grid during off peak and use it in peak

        • +5

          PW2 owner here and it is 100% worth it if you are on a time of use plan in NSW.

          Even if you dont generate any solar in a day (say rain all day) you can fill the battery at off-peak rates and discharge the battery at peak time.

          In my case that is saving 66% as my peak rate is triple my off-peak (not allowing for ~5% loss when charging/discharging).

          I am going to get a second battery so I never will be charged peak rates again….
