South Australia’s Home Battery Scheme
From October 2018, 40,000 South Australian households can access $100 million in State Government subsidies and $100 million in loans to pay for the installation of home battery systems.

While the subsidy is available to all South Australians, Energy Concession Holders are eligible to access a higher subsidy, ensuring low-income households are supported to access the Scheme.

The subsidy is applied to the battery component only, participating households can apply for finance made available through the Commonwealth Government’s Clean Energy Finance Corporation to help pay for the balance of the battery and to purchase new or additional solar panels, if required.

The subsidy is calculated on the kilowatt hour capacity of the battery being installed, and capped for everyone at a maximum of $6,000 per battery installed.

Home Battery Scheme subsidy levels
Energy concession holder $600.00 per kilowatt hour (kWh)
All other households $500.00 per kilowatt hour (kWh)
A set of minimum technical requirements for battery systems has been developed to ensure the batteries are safe, reliable and capable of being recruited into a virtual power plant.

While households are able to choose whether or not their home battery system operates as part of a virtual power plant, the ability to aggregate home battery systems - either now or at a future point in time - creates opportunities to address network issues and smooth loads by balancing out peak power demands.

A dedicated website is available to assist South Australians consider their suitability for a home battery system, choose between approved products and system providers, access the subsidy and apply for finance, if required. Visit: www.homebatteryscheme.sa.gov.au. Alternatively households can call, 8463 3555.

Businesses interested in becoming system providers can learn more about the application process, by visiting www.homebatteryscheme.sa.gov.au/become-a-provider

        While visiting family in Outback SA
        a guy showed-up at their door, there

        ie, to be eligible for the subsidy.

        (That doesn't make sense to me, ie:
        because the Virtual Power Station
        should be happy to take power from
        where ever it comes.

        Right?)

    Can you go off grid with this system?

    • +2 votes

      in a way, yes. but you are still required to have electricity connection by law in some states.

      • +3 votes

        And you'd still want to be connected to the grid anyway so that you can export excess solar energy (from which you earn money).

        • +6 votes

          Well that depends how much you get paid for your export the "Feed In Tariff" or FIT.

          In WA you get 7c per unit exported BUT you pay 95c a day to be connected to the grid.
          With this 5kw inverter you'll do a max of 30 units generated a day (probably average out at 25 units a day year round).
          Considering you'll be using your excess to recharge the battery you probably won't export more than 5 units a day (logic average Aussie household consumes around 25 units a day).

          So 5 extra units exported at 7 cents= 35 cents.
          So in WA my annual connection fee (.95 x 365= $347)
          So in WA my annual export to grid (.35 x 365= $127)

          SO IN MY SITUATION I WOULD SAVE $220 PER YEAR I WENT OFF GRID.

          ymmv

          • +2 votes

            @scratchy: $220/year vs the risk of running out of electricity after a couple of rainy days in winter.
            ymmv indeed.

          • +1 vote

            @scratchy: Scratchy, don't forget to add in the sign up incentives you can get for switching energy providers. Most are around $120 (look on cashrewards), and you can do it every 6 months without much issue.

            Simply Energy are offering $260 in bill credits over 2 years (basically meaning little cost for a grid connection), and AGL providing $480 over 2 years if you have an Elect vehicle (this means the cost of grid connection is basically zero as their day supply charge is around 75c/ day).

            Ie, with this deal, you can save $2990 by not getting it! and staying on the grid. This is what stops me from going ahead with a battery. I have a small generator for blackouts if needed, and most batteries wont work in blackouts anyway without paying a higher cost than the cost of a generator).

            *disclaimer..this guy ports.

            Just some food for thought.

    •  

      It'd be super tight through the depths of Winter when you're generating only 2-3kWh across the entire day.

      My house consumes 2.5kWh/day in standby usage alone, just running the fridge, modem, Clock Radio and TV on standby.

      •  

        @scubacoles This system will make 5kw per hour in decent conditions. You might see 40+ kw generated after a sunny day

        • +2 votes

          Did you actually read my comment?
          In the middle of Winter on those cold overcast days where there is very little insolation you'll be lucky to generate 3kWh (Source - my own 5kW system performance).
          Get a few overcast days in a row and use any electricity outside of the extreme basics and your battery is going to be rapidly exhausted if you're off-grid.
          If you've got electric Hot Water, forget it!

      • +2 votes

        Those days are very rare, I've got data from my own system for 9 years.

        Only 5 days in 9 years were below 3kWh. The lowest I got for 2 consecutive days was 9.5kWh. The lowest for 3 consecutive days 24kWh.

        That 3-day result is more than I use. For both the 2-day and 1-day result this battery system would have been more than sufficient.

        •  

          It all depends on your usage, but in my case, it's not logical
          13kWh is about what my house uses on average per day (this with Gas Hot Water, Heating and Stove).
          When you're generating only a few kWh and you're using your full battery capacity it only takes 2 poor days to realise that going Off-Grid wasn't such a great idea.
          In all 3 of your scenario's * , my house is out of power (or on power rationing) for at least half a day. Added to this, the battery is being kept at VERY low levels, which is (likely) not good for its longevity.

          *Also factor that you're going to lose 15-20% round trip through the battery.

          •  

            @scubacoles: I'm surprised that your house uses 13 a day when the standby and fridge only come to 2.5. Where does it all go? Especially since you have gas for the big consumers.

            In any case you have 3 options then:
            * rule out batteries
            * get more batteries
            * add a small generator

            In my own situation (unfortunately only theoretical, since WA doesn't have the same generous subsidies), I'd be happy to reduce the battery size to about 10kWh and have a cheap 2kW generator to back it up, knowing that that generator would only be used between 0 and 20 hours each year.

              @team teri: Washing Machine, Dishwasher, Oven, Dryer, Coffee machine/Kettle/Toaster, Watching TV, Lights, Computers, AC during Summer.
              All the usual stuff.
              Looking back through my Whole House Consumption readings, I've probably over-estimnated our usage through Winter, it's probably more like 10kWh/day on Average through Winter and 15kWh through Summer (cause of our Gas heating, we use less power through Winter than Summer), but still run over 13kWh for the day on Laundry days.

              These batteries are DIRT Cheap though. I am tempted to investigate further as 13kWh batteries at less than $5000 out of pocket puts them into profit territory (on grid and before factoring any future VPP possibilities) based on my previous calculations when this SA Govt rebate first came in.

      No.
      Grid-connected inverters tend to only produce active power so the grid is still needed for reactive power. More expensive off-grid inverters would be able to absorb the reactive power.

    Quick Facts about the Home Battery Scheme:

    The subsidy is available for the installation of home battery systems.
    The subsidy will be up to $6000 depending on the size of the battery and whether the customer is an Energy Concession Holder.
    $100 million subsidies for up to 40,000 SA households are eligible for the subsidy.
    An additional $100 million low interest loans are available from the Clean Energy Finance Corporation to help households pay for the balance of the subsidised battery and new or additional solar if required.

    I have a 4kw system with Q-CELL Panels and a SMA inverter. Noticed the panels aren't producing any more than 3kw max.

    Went to clean the panels and noticed a heap of silver 'shorts' running through the panels. Called the installer (Solar Choice), they say they are no longer in business/ partnership with Solar Choice and are now known as Hale and Baulm Plumbing, and only do plumbing now. Dodgy, but that's solar!

    So called the manufacturer, sent photos and completed forms. They claim the 'snail trails' are acceptable. But never quantify how many 'trails' are acceptable. Anyone else got through this before I hit up Office of Fair Trading?

    or now thinking, do I just get this and replace the lot (such a waste though). ..and so everyone knows to avoid Q-CELLS, that's Q-CELLS who are ducking and weaving on the warranty.

    • +1 vote

      Warranty On qcell is pretty good usually (from what I've read), but installer going out of business is the issue

      Likely need to pay a solar electrician to diagnose the issue/faulty panels and raise it with qcell..still gonna cost you some $ though as your original installer isn't an option (and qcell don't pay installer fees on panel warranties from memory)

    • +9 votes

      3kW from panels rated 4kW is not too far off from what you'd expect from a system where everything works perfectly fine.

      Panels are rated at standard test conditions (STC), that assumes 1000W/m2 insolation. Depending on your location and the orientation of the panels you might never get that. Even without any shade, which would make a huge difference again.

      Then the main factor is cell temperature. Testing is done with cells at 25 degrees. On a day with full (1000W/m2) insolation your cells will quickly heat up to around 60 degrees. For each degree you lose about 0.5% of output. That's 17% loss in that example, leaving you 83%.

      Add in inverter efficiency of perhaps 95%.

      So full insolation on 4kW panels will result in 3.15 kW AC output (4x0.83x0.95). Pretty close to what you are getting. Probably close enough that a warranty claim would not succeed, save yourself the $$$ and time.

      • +1 vote

        This… It's also likely your inverter is 3kw, and oversized by the recommended 33% to give you the 4kw of panels.

        Position of panels in relation to North will also have an effect.

        •  

          Good point, would need to check inverter model/capacity

        •  

          Cheers, but it is definitely a 4kw inverter (4000TL SMA). House faces NNE, no shade/ tree interference.

          •  

            @tunzafun001: I have 10.35kw system and if i get a sun burst through the clouds i hit 10.100kwh and thats with 2/3 west(slightly south😳) and 1/3 north
            So i cant see 3kw for a 4kw system is good enough especially with decent inverter and panels

      •  

        Cheers for this. I wish Q Cells put it in a simple context for me. I will uses your numbers for theoretical peak output. As for the 5% inverter efficiency, wouldn't this be what is lost when feeding back to the actual grid, and not on the PV generated number on the inverter read out itself? (hope that makes sense). Ie the inverter shows what is coming from the panels (with 17% loss) and then the smart meter would show a further 5% loss?

        So, this week we have had perfectly clear skies (with warm sun, yet really cold winds) with max temps 15- 17C, with an apparent temp of 7- 8C. So I think this is about as good as it will get for solar production. The solar energy is definitely there as our Solahart hot water is around 55C (and I have it turned off - p.s. these things are amazing). Feels cold outside, yet water is hot with no electricity/ gas usage whatsoever. We don't have any trees / shade interference and the house faces NNE with a 25 degree roof pitch. The read out from the 4000TL SMA inverter peaks in the high 2800's. So I think some panels aren't firing on all cylinders. I also had someone out today to quote on basically updating to this deal, and he said it looked like 2 panels at least were cactus. He think likely damaged on the install.

        So, getting back to your info, it looks like it will come down to numbers. Are 2 panels responsible for bringing the total output down by around 300w (probably), and is it enough to trigger warranty conditions. Then who is actually responsible for the cracks in the panels (the installer who no longer exists? the transport company? or a panel manufacturer who provided a panel too fragile to be handled by the prior 2 (not fit for purpose).

        Finally, this 4kw Q-Peak panel system was $13 200 (after all rebates) in 2012. None of it can be used if I go with this 6.6kw offer :(

        Any ideas if I could use Tindo panels with their own built in inverters on the back of the panel to bring the system up to 6kw? Or run them on a seperate circuit to the current system. I have seen these going for $500 for 3kw (panels only).

        • +1 vote

          Your inverter shows the AC output, after conversion losses. That's also what it is rated at, the 4kW are AC. You might have some additional loss on the way to the meter, but I'd be very surprised if that is more than 1%, that would indicate undersized wires.

          Why the need to get to 6kW solar in total?

          If you have to: The 4000TL has 2 MPPT trackers, suitable for 2 independent inputs. Are they both used? If only one is used by the existing panels you could perhaps add an extra 2kW of panels to the second input. If you put them on a different roof area (i.e. facing NW) you would get a very long peak each sunny day during which the inverter is maxed out at 4kW output.

          No idea how the Growatt batteries could be integrated into the system. If they are AC coupled they could easily charge from AC, but how to communicate the when to charge? Can they perhaps connect to the blutooth of the inverter to know its output?

          •  

            @team teri: Legend, very informative again! Looking to go 6kw for winter. In summer we had a $15 bill credit, Winter was a sub $200 bill for 3 months. Solar Hotwater booster required! Plus I drive a PHEV, so that chews up a bit.

            How would I know how many inputs are used? Can I isolate the inverter from the grid, then open it up at night to be uber safe and look for something? The Bluetooth feature is currently disabled, so I need to open it one day to activate it anyway.

            We do have some vacant roof area on a W aspect that would see full sun from 2pm onwards, but I thought this would bring the whole system down prior to 2pm. But you are saying that the inputs are independent? That would be ideal.

            Does the second row need to be the same panel output as string 1. Ie, does this mean I need to find 255w panels with the same resistance or whatever to match the Q Cells that are up there? (basically, do I need to find more Q cells)?

            As for batteries, I don't think I will go for the Growatt. AGL give me a $60 bill credit every 3 months with equal to the best rate I can find anyway 0.75 supply charge/ 17c feed in / 0.33 peak/ 0.18 controlled laod (So I'm basically not paying for the grid anyway).

            But I did see these Tindo solar panels that apparently don't need an inverter? If I can just add a few extra kw of them that would be great?

            • +2 votes

              @tunzafun001: No need to open up the inverter, at the bottom left of the display you should see a symbol for PV panels. It should alternate between input A and input B every 10 seconds or so. If you get data (PV Voltage and current) for both A and B, then both inputs are already in use. If it shows data for only A or B, then only one input is in use.

              The two inputs have independent MPPT. You can have different panels in different configurations on them, facing in different directions.

              Also, technically you could have a second system with a second inverter, you would not need to use Tindo panels. The only issue here in WA is that there is a 5kW limit for total inverter capacity. No idea what the rules are in SA.

      I wouldn't worry about 'premium panels' or warranties. Our 7 yr old 4kw solar system used premium German panels at a cost of $13 000. A couple of panels now potentially have issues and the installer no longer exists (no doubt phoenixed as someone else) and the manufacturer requires you to get the installer to prove they are faulty. So not worth the paper it's written on.

      Basically, find a price that will recover costs in around 5 years.

    Anyone know if you can go beyond the 5kw single phase limit with a battery? Ie, add the battery to a 3kw off grid system (which I already have). Install this new 6.6kw / 5kw system and connect to the grid?
