  My advice is to get a battery now, change in regulations or an inspection requirement could mean no one will install the battery or the cost will be to high to bother. Also cheapest isn't always the best. Make sure you have your last 2 years of usage if you can so you get the right amount t of kw

    Don’t think I’ll look at s battery yet as payback is too long and reliability yet to be proven .
    Thanks

      We are looking at Solar in Melbourne and have come to a similar conclusion. A battery will add $10,000 dollars to the cost of installation so we will put it in vanilla for now and do the upgrade when the battery technology because cheaper and better.

    Worst advise possible. OP, Please DO NOT get a battery unless you want to because u simply like the idea of it.

  Would be keen to know a bit about this too.
  Way too many options and feel overwhelmed.

  Battery is a very questionable proposition. The outlay is very high and they only have a lifespan of some 10 years, so you would need to store/use around $1,000 of electricity every year.
  In terms of installers make sure you choose a company that has been around for a long time and who has a good reputation. Bo point buying panels with a 20 year warranty if the installer is no longer around.

    Is the ten year estimate generous? No battery I have owned has lasted 10 years.

      Very generous. $1,000/pa is net difference you need to make with the battery, not overall consumption.

      Having said that, I am considering one but will likely wait for some major breakthrough in battery degradation and/or cost before pulling the trigger. We get outages here about 7-8 times a year and it would be nice to have reliability.

        Yeah, as tshow says, the maths falls over once you factor in that the enery you store isn't actually free… You get paid to export it.
        Added to the fact you have round trip losses such that you can use only ~80% of what you store and the maths for batteries gets even less favourable.

  I wouldn't go with a battery yet. The payback is too long.

  The Jinko are a good budget panel. We fitted Jinko last year and they perform as advertised. We also looked at LG and Solar Edge and couldn't see the value in the higher price.

  We got a Zever Inverter and it's been flawless. The Fronius has a better reputation but it was $800 more and we needed a short payback period as we aren't sure we'll be here in 5 years.
  A work Colleague fitted Goodwe/jinko - 10 year warranty and he thinks it's a great system for the money.

  I fitted a really cheap & nasty 1.5kw system from Origin Energy to my old house in 2009. I think the inverter sounded like "Sony" (but it wasn't) and the panels were panasonic (I've thrown all the paperwork away). The inverter died within 3 months and Origin replaced it with a new unit. It died again in 2017 (10 year warranty) and Origin replaced it with a rebuilt unit (manufacturer has disapeared) without argument. It's still chugging away so i guess a good warranty and a solid, reliable supplier/installer are more important than anything else.

    Adelaide 5KW Solar owner here.
    I've had my panels over 5 years now and have been tracking generation and consumption for 4.5 years.
    Based on our usage, a battery even with the Government rebate currently on offer would barely break even over 10 years despite the fact we have already paid down the cost of install of the Solar System!

    My assumptions are that the price of electricity (both Import and Export) and our usage would remain unchanged from today.

    In the event that a Virtual Power Plant type system eventuates where we could Export power back to the grid for more than the current rates, that might change the equation.

      What panel/inverter?

      NVM, saw your other comment.

  These guys are the result of a 2016 merger between the 2 most highly rated Solar Installers in Adelaide (ACE Solar and Electrical and Adelaide Electrical Solar & Security) on Whirlpool forums from 5 years ago.

  I had my system installed by ACE Solar and Electrical with a mix of Chinese panels and SMA Inverter.
  The only problem to date with my 5 year old system was a blown MOV (which is a sacrificial part protecting the Inverter from Power surges) which they replaced for free, despite me being happy to pay.

  I’d recommend Goliath or Living Energy.

    Which one did you use?
