    Indeed mate...
    I've never used Amazon for much anyway, a couple of books, couple of movies is about it; right from the outset of their web presence.
    Will never use it again though, doubt they will miss me.

    Add to that, Amazon only pay about 2% tax.
    But they do have many friends in Canberra.

    It's the Safety, as well as the Energy Storage capacity, that grabbed my interest too.
    Definitely getting there I believe.

    That nail safety test was pretty impressive Mal, not something you would want to do with lithium ion.

    Something else to add in to the mix, and quite interesting in its own right...

    The Victorian Government (“Guv-ah-mentt”) brought in a new law saying the power companies have to make it easier to see what the cheapest elec-trickery plans are. I’m still waiting to hear about that.

    What would you suggest I do, TampIT?

    G'day pamount

    I only just saw this question. FYI, I do not keep track of posts - too many alligators in my current swamp for that.

    We are using about 15 to 20KWH per day here across the whole year - including air con in summer / reverse cycle in winter. You are using below 1/2 of that so I presume you also have gas? Or you are a very low power user? If the answer is gas, you may consider a plan to move away from that as well (why pay even more "daily service charges" for redundant technology?). That may increase the size of "solar need" in your case.

    Semi related hint: if you are going to install a rooftop solar hot water system, please get a tank of marine grade stainless - all other alternatives should not even be on the market in my view, especially sacrificial anodes. The number of friends with leaky tanks is nothing short of insane - and they get told they should have got it serviced, which just means adding another sacrificial anode (at another $300ish) to last for another 3 years before another service is needed. Sheesh. Payback would be approaching infinity or longer. My 1983 system is still going strong with no servicing needed (yet).

    Back to solar PV. Ironically, the solar panel system here would be plenty for your needs. We "only" have 3KW of panels, most new installs are 5 to 6.5KW these days. That is a fancy way of saying you can go for a pretty small, cheap install compared to most.

    BTW, one of the installers here is scrapping 2 or 3 working systems a week (complete with all mounting hardware) as the old 48 cents per KWH runs out and early installers are forced onto the 6.9 cents per KWH rate for their exported power. They are upgrading in droves, and it is cheaper to scrap their old system and replace the whole shooting match with a higher capacity one. Those systems are usually from 1 to 3KW, even a 1KW would be worth it in your case at a cost of near zero... plus a little of your time and labor. One friend even arranged to do the removal and the installer thanked him profusely. Needless to say, said friend knew exactly how everything fitted together at his house by taking a few photos during the teardown. Win win.

    If you happen to be pretty handy in a DIY sense, I would find someone (via your local installers) with a working 2+KW system that is doing an upgrade and basically reinstall their whole "old system" at your abode. Be aware, you will need a sparky to do the final hookup - unless you enjoy being a homeless arsonist...

    Hope this helps.

    Thorium reactors are a candidate to cover a chunk of that.

    I read an article today regarding the worlds electricity use through internal news a work today.
    An interesting thing is the world will consume double the amount of electricity in 2050 than it does now.
    The worlds electricity production doubled between 1990 and 2015.

    It is estimated that two billion more people will have access to electricity by 2050.

    Can the world generate this much more sustainably?

    Something to think about.

    The technon both panels and batteries is soon to jump forward. They are saying light wave rectifiers are on the horizon

    Think there might be a limited industrial uses for this though, flow batteries don't do too well on high discharge rates. Unless of course they solved that using gel... which then might make things interesting...
    Did anyone find any mention of it's cycle life?
    Looks like it's still in development phase?

    The Solar Quotes website has an interesting home battery comparison webpage, which appears to be updated regularly: https://www.solarquotes.com.au/batte...parison-table/

    The Redflow ZCell is still the only flow battery listed. It's hard not to imagine that the home battery market will advance a fair way over the next few years!

    50% of my bill is the line rental (whatever they call it). Of the 50% usage I have, 50% of that is the fridge keeping the ice machine cold. The fridge is 50¢ per day in usage...
    I wonder if I could disco the power and run the genset on natural gas...

    Pamount, probably worth giving TampIt a clue about your circumstances. Do you live in a house, unit, rent or own? Interesting in Sydney there was a company supllying solar to rental accommodation (like student blocks), then supplying the electricity at a much lower rate to residents. Win for all three parties.




    Ps this is the Vic government comparison site - https://compare.energy.vic.gov.au/
