      To ensure that your place does not burn down and blame them and sue them for damages. It's also a requirement for the sparky to check before they do any work.

      Be aware that the requirements have changed a few times over the last 40 years, so what was compliant 20 years ago may not be compliant now.

      In lab conditions without factoring any transmission loss or inverter loss or panel degridation.

      I just got a new install the other day, 13.2kw of panels and highest output has been 9.5kw so far (In Tasmania)

        Has nothing to do with that - peak sun only happens for a short period each day (i.e. 6.6kw may only be 15min in summer). So typically panels are 33% oversized relative to the inverter.

          • Duff5000 on 14/12/2024 - 18:43
            +7

            @Kegsta: No, nothing to do with lab conditions.

            What they are telling you is they install more panels than the inverter can actually use. That way the inverter is hitting its rated max far more often. Its a waste to do otherwise.

            So you probably have 13.2kw of panels but a 10kw inverter. You cant get 13.2kw, lab conditions or not.

            If you only installed 10kw of panels you would be getting about 8 much of the day and rarely getting 10. Just overprovision the panels so you get 10 far more often.

            • onelove on 14/12/2024 - 18:54

              @Duff5000: Correct. Electricity output is limited by inverter in this case.

            • Kegsta on 14/12/2024 - 19:14

              @Duff5000: Yes I know that, but the original question was asking why doesn't 6.6kw of panels output 6.6kw of electricity?

              • adpaholic on 14/12/2024 - 22:06

                @Kegsta: The 6.6kW is the maximum capacity under ideal conditions. Actual output is lower due to factors like weather, panel orientation, temperature, and system losses (e.g., inverter efficiency). As inverter only 5kw, so yes sometime some energy are wasted.

              @Duff5000:

              Its a waste to do otherwise.

              I still don't understand how it is not a waste to overprovision panels like this. I mean, buying a 6.6kW inverter is not much more expensive than a 5kW one, but 15 panels instead of 12 definitely is. Why don't they simply install a 6.6kW inverter so that we don't lose the area under the curve above the 5kW line? There must be a regulatory reason.

              • cheaptech20 on 14/12/2024 - 19:37

                @bio: Incorrect - panels are dirt cheap, inverters ramp up in price…

                • bio on 14/12/2024 - 20:01
                  +3

                  @cheaptech20: How come? I couldn't find a 6.6kW one, but for example a 5kW GoodWe inverter (https://www.solarbatteriesonline.com.au/product/gw5000d-ns/) is only $40 more expensive than a 4.2kW one (https://www.solarbatteriesonline.com.au/product/gw4200d-ns/).

                  By this logic a 4.2kW inverter requires 13 panels (instead of 10) and I doubt getting 3 more panels installed would be cheaper than $40.

                  Edit: Ok, reading more about it, the main reason seems to be CEC only allows 5kW inverters for single phase, so overprovisioning the panels is a cheap way to maximise energy.

                    @bio:

                    By this logic a 4.2kW inverter requires 13 panels

                    It doesn't require 13 panels, it's just more efficient usage to over-provision because the earth moves relative to the sun so you want to try and capture the sun for more hours in the day.
                    ie. Let's say you just had 5kW of panels facing North, they'd only peak out for a couple of hours in the middle of the day, so maybe 5kW x 3 hours But by over-provisioning with extra panels also facing East and West you grab a little bit extra in the morning and a little bit extra in the afternoon, meaning you get the original 5kW x 3, plus another maybe 2kW x 2 in the morning, plus maybe another 2kW x 2 in the afternoon. By over-provisioning by 33% you can gain an extra ~50%+ return on investment

                      @1st-Amendment: My point is with a higher rated inverter you'd gain more. By over provisioning you are not "gaining" anything. You are just discarding some of your production. Yes, the curve is flatter, but total daily production is lower.

                      I got my answer from Google, though. Installing a 5kW inverter is cheaper than, say, a 8kW because 5kW is the maximum allowed for single phase.

                        By over provisioning you are not "gaining" anything

                        Well you are, as I just explained… This maybe news to you but the earth rotates, so relative to your roof, the sun moves across the sky so having more panels actually gains you more production as they catch more sun for more hours throughout the day.

                        You are just discarding some of your production

                        At sometimes right in the middle of the day you are, but most other times, especially at below peak, which his most often, you are gaining. Because you are grabbing more sun longer throughout the day. So for less cost, you are netting more overall energy.

                        Yes, the curve is flatter, but total daily production is lower.

                        A flatter wider curve means more area under the curve. You might want go back to year 9 Maths to brush up on how that works.

                        Or, just imagine for a moment that people in the industry might know more about this than you. Either that or maybe the whole over-provisioning thing is a giant scam and only you've figured out! Call Four Corners, you've got a hot scoop!

                        I got my answer from Google,

                        That's only half the answer. It doesn't answer why installs don't just stick to the same size as the inverter (ie 5kW) rather than aim for a ~33% over-provision.

                +1

                @BatmanAU: No worries. Technically speaking panels can often exceed their rated power in ideal conditions.

                IIRC they test with 1000w/m2 which the sun can exceed in some circumstances and at a set temperature (28?). On a really hot day you will be well above that temp and output will be reduced. One a windy clear cool day you can be well below that temp and the penels can output a bit more than rated. (so yes, ignore kegsta above)

                Over the day though time spent at maximum is going to be very low. Another thing we didn't discus is placement. If they all face north you get a nice peak in the middle of the day but mornings and afternoon you are way down on power. You can overprovision and have some panels aimed to catch early and late sun, now you get more max inverter output generation all day but its impossible to ever reach the total of all panels as they are not all hit at the same time.

    • gakko on 14/12/2024 - 20:06

      At peak it might but a lot of solar input is below peak and having more than 5kw of panels just means you do better when the sun isn't supplying peak. We occasionally top out at 5kw but the benefit of having more panels is when conditions are not as bright.

              No. Most UV won't even reach the solar cells, as the glass on the front of the panels will block much of it.

        • Russ on 15/12/2024 - 15:07

          how much would cloud affect it?

          Quite a lot. My solar system (in Brisbane) typically puts out 24kWh on a cloudless day. On a rainy day with continuous cloud cover I typically get 5kWh to 8kWh.

          • BatmanAU on 15/12/2024 - 16:59

            @Russ: Crazy drop, to put into context, what would get powered by say 5kwh, TV and Washer?

              +1

              @BatmanAU:

              what would get powered by say 5kwh

              Remember, 5kWh is an energy rating, it's power multiplied by time. So it is equivalent to 5kW for 1 hour, 500W for 10 hours, 208W for 24 hours, or anything in-between. So it depends how long you want to power your chosen appliance for.

              Power used by typical household equipment:
              3600W electric hot-water system
              2400W electric fan heater
              1800W-2400W electric kettle
              1000W microwave oven
              100W-400W desktop PC + monitor

              In general, the order of power consumption from highest to lowest goes:

              • Things intended to produce heat
              • Things intended to produce cold (e.g. fridge, air conditioner)
              • Things that are primarily a large motor (e.g. washing machine)
              • Things with cooling fans or blow warmed air out (e.g. desktop PC, power tools)
              • Things that get warm in operation (e.g. TV)
              • Almost everything else

              Of these things, there's a lot of variation. A huge plasma TV uses more power than a small LCD TV. Air conditioners use more power on hot days, and so on.

              If you look at your electricity bill, it will almost certainly tell you your average daily power usage in kWh. That's probably a better way to compare what a solar system outputs, you may discover that 5kWh is only a third of your normal power usage.

      • Italkdigital on 14/12/2024 - 21:29

        Interesting read above, thanks, so for us noobs, so basically having more panels helps, a bit like having more surfice area on a cpu heatsink (aka the amount of panels) giving more powerful cooling effect from air of a cpu fan (aka the sun), obvisously panels are at different orientation and locations will get different sunlight at different time of day the sun is set at, why better having the extra panels were possible on ones roof

        I think us noobs, say a example a 13kwh panel setup are unknowingly thinking the behaviour is as if its say one example metre by metre one 13kwh panel, facing correctly and orientated to the sun correctly and generating close too its full capacity of 13kwh, nope, actually got to think/picture it as its a setup of numerous panels, totaling 13kwh in capacity but impossible too generate close to its capacity of 13kwh, cause all panels are spread over an area of ones roof at different angles to the sun at different times of the day so why it will ever generate to close too 13kwh

        Why better too over provision panels, not to genarate more power output at one point of time but to catch more sunlight throughout the day to genarate more power over the day sunlight is available from and even more helpful on cloudy days

        Ok reading above is giving myself a headache Lolz 😆

        • gakko on 15/12/2024 - 10:55

          Yeah exactly. More likely to get 4kw in non peak conditions if you have more panels, for example. When there's full overcast it's basically zero though.

        If you're using the power, then no. But I've seen a few comments here on OzBargain suggesting that signing up to a virtual power plant, so you export your power at times when the wholesale power price is high, can either break even or turn a small profit.

        I don't have a battery myself, but am interested.

      Then just get a Powerwall 3 or Sigenergy system which has an inbuilt inverter.

    Anyone know about putting individual solar on apartments? 10 flats across 2 levels

    • salmon123 on 14/12/2024 - 18:27

      What's your question?

      Typically the roof is "common property" in an apartment building and you need strata approval to put up solar panels. There's various configurations that you can use to either share the panels or have a dedicated solar system for a single apartment (eg town house). Lots of articles online about it.

      • Guzd on 14/12/2024 - 18:31

        Sorry good point. I know no one in my complex has any money so a complex sharing system is likely out of the question. I guess I’m wondering if anyone has experience putting their own system on common property (perhaps on only a portion of the roof which is the percentage size representing the apartment)

        • salmon123 on 14/12/2024 - 18:44

          Yes - it's been done - just needs strata approval.

          The reality is the approval get buried in some general meeting notice and no one really looks at them (unless there's a big proportion of owner occupiers). You just need to sweet talk the strata committee or strata manager (whichever of the two is making the decisions) into allowing it.

          The system doesn't have to be in proportion to your unit entitlement or roof space allocation - the "owners" can give you permission to take up the whole roof if they deem fit. They can also cover the cost if they're feeling generous.

            @salmon123: The whole point would be the capital costs and return. So any credits obtained from the installation, assuming it goes ahead, would be to discount future strata levy.

            Unless it's got a big sinking fund or that vote and set up a special levy, those who aren't in for the long run wouldn't be interested in this investment

            • salmon123 on 14/12/2024 - 19:39

              @Butterfly Gocha:

              The whole point would be the capital costs and return.

              It sounds like @Guzd is looking for a single apartment solution rather than a shared solution.

              those who aren't in for the long run wouldn't be interested in this investment

              You'd be surprised how many investors never even look at the General Meeting minutes.

        • askvictor on 14/12/2024 - 20:21

          There's currently a Victorian Government rebate for apartment solar, so it might not be as expensive as other people might think.

          Otherwise, something that's gaining adoption in Europe is balcony-mounted panels. No idea about if they're feasible here though.

          • 1st-Amendment on 15/12/2024 - 07:17

            @askvictor:

            The average European apartment has a balcony the size of a postage stamp, you'd struggle to get a single panel on one. How does that work?

            • Russ on 15/12/2024 - 15:20

              @1st-Amendment: Given how far north much of Europe is, you could probably mount the panels vertically on the southern wall, and still get good power out of them.

    do they have packages with Tesla house batteries? I want to do a off the grid setup.

      Do you actually live in an off-grid area or just like the idea of having your house disconnected from the grid?

      I don't think the numbers stack up for city dwellers to have a comfortable off-grid set up (yet).

        i want to be able to switch on or off the grid when ever i want the tesla batteries have a thingy that lets you do that.

        • askvictor on 14/12/2024 - 20:26

          You'd need a hybrid inverter; they cost a few times more than a normal inverter

      • BargainBogan99 on 14/12/2024 - 19:16

        The numbers are stacking up, even more so with the threat of being charged for the privilege of feeding solar back into the grid. Id happily switch to full battery and only draw from grid in emergencies

          Both of you guys need to do more reading on what off-grid actually means.

          You're both still talking about grid connected systems and possibly a virtual power plant.

          • kungfuman on 01/01/2025 - 17:47

            @salmon123: You know how a UPS works right? I want the same thing but with house batteries when the grid drops the house can still function independently

      Do you have 60k or so to throw at it?

  • browser on 14/12/2024 - 18:42

    Is 6.6kW a standard setup or more panels the better? If there's space for 20 panels, is upgrading to 8.8kW an option?

    Solar Quotes' brand chart maybe a little confusing, the brands are alphabetically placed, Canadian Solar is at the top because of its name rather than brand reputation.

    • WhyAmICommenting on 15/12/2024 - 10:33

      Always get as many panels as you can manage because no one will touch it once its all working unless there’s an actual fault under warranty.

      • browser on 15/12/2024 - 11:10

        So they just package 5kW, 6.6kW, 9.9kW, etc to make it easy to quote and promo, but you can add more panels to maximum roof space?

        If there is space for 18 panels, this could well be 440w x 18 = 7.9kW system, but may be to upgrade the inverter, right?

        • WhyAmICommenting on 15/12/2024 - 13:26

          Usually you put about 1 to 1.33 times the inverter in panels. I have 5kw panels and inverter - wish I’d put at least 6kw in panels but too late now.

          To expand I’d need to add an entire new system due to warranty etc

  • naru6705 on 14/12/2024 - 18:50

      This is a risk for all solar installers. Even long-established businesses have gone under.

    • CommuterPolluter on 15/12/2024 - 00:01

      Most companies in the VEU space are dodgy because Govt is throwing money at them. Nothing to do about it.

        Yes, thats why I went with a big (ie not just solar) company to install mine even if they were more expensive
