    People are getting charged for their Excess Solar because the Electricity Suppliers and Governments aren't spending enough on Batteries. There needs to be a Decentralisation plan where Suburbs get Container sized Batteries to soak up their daily output and get it back at night. Which would make prices very low.

      mate google search "battery storage map australia", it's been going absolutely nuts, the amount of taxes we are spending on them must be ridiculous
      and the vast majority of it isn't even LFP but NCM which is far more expensive, especially when the government locked in the contracts probably years ago

      @keithwilson1554 I used to think the same until I realised that the grid needs cash flow.
      Most electricity is dirt cheap.
      Feedin 5cents kWh
      Grid supply 50cents kWh
      So, if you can think how the grid can keep its cash flow, you might have the grid supporting the transition to renewables.

    Steve, this is a great attempt to explain new technology in layman's terms! Not all PV panels are equal in performance or longevity. For batteries that is even more so! One should also consider fire risks, insurance costs and old fashioned ROI. We are stuck with the need for the Grid, because no small domestic PV system can possibly provide for all situations. And what do you do when the Grid collapses? Currently your PV system is automatically shut down via your inverter during a blackout, locking you out of any electrical supply!

    A good video Steve so thanks. One feature missing from the Tesla Powerwall is the ability to set how/when it should use excess solar to recharge. This feature would allow owners to use their excess solar during peak periods for recharging instead of incurring negative FITs when the grid has issues with the excess supply. You can set charging times for cars and heat pump hot water systems but not the Powerwall unfortunately. Cheers

      The real economic relationship is between the grid owners and the customers.
      The other observation is that the actual grid was an expensive necessity for the customers and was built gradually over 10 decades with national wealth and government spending.
      Also, if electricity were to replace fossil fuels, then 7 times more electricity is needed.
      The grid capacity has to be 7 TIMES bigger.
      Nuclear promoters say that the real cost of electricity to the customers is the grid costs plus a little for the generators.
      Basically electricity is dirt cheap but grid electricity to the customers is expensive.
      So even free electricity into the grid costs customers a fixed amount per kWh.
      So, to jump forward, we need to protect the grid and have all customers' rooftops PV be able to self supply and replace all the customers' fossil fuels and electricity.
      Furthermore, the customers should supply the grid with dirt cheap electricity, and the industrial users take more electricity to replace their fossil fueled processes.
      74% of all electricity is consumed in homes and buildings.
      So, 'switch this around'.
      With Battery Vehicles oversized battery usually parked 23hrs every day and V2G and selfparking selfplug-in at every building carpark, then the numbers show it could all work with the original national grid, with minimal modifications.

    I'd get an extra $700 a year credit if I had a battery so it would take much longer for me to pay off. I have a 10kw system and I went from a $5500/year bill to a $500/year credit.
    I'm in Queensland where I receive 13cents for what I export and 32cents for what I purchase at night.
    If the multiple between the tariff and purchase becomes greater, than I might start to have a bill again. That $700/year extra credit from having a battery will increase to a point that it will be worth it. I guess that's bound to happen with so many people going for solar. Energy providers will try what they can to get money from us. This includes higher buy price, lower feed in tariff and remote controlling when we can actually export

    Hi Steve, at home in the Illawarra also.
    We have a 5kW inverter and have two powerwalls installed and using Amber as our energy supplier.
    We also have a Tesla model Y which is currently on the Beta "Amber beta EVs" at the moment.
    The inverter is also controlled by the Amber app and the export is curtailed if the feed in prices go to far negative.
    Best use case using Amber is with batteries which assist when there has been some big fluctuations in the wholesale pricing.
    We have also gained very well at times but as I say to people there has been quite an investment up front to enable this.
    One day earlier this year we earned over $240 with our system, so one can only imagine how much the big generators made that day.

      The Amber app has similar options to the Tesla app but using both together seems to confuse each other depending upon settings. I am just using the Amber app settings at present but still use the Tesla app to view some graphics that the Amber app doesn't show. They compliment each other and I will use the Tesla app to override if I need to get a charge outside of the Amber's set parameters.
      Excess solar is used to charge the car and homes batteries first depending upon what the current wholesale prices are.
