Greetings from South Australia. Thanks for another excellent video, Dave. I like your no-BS way of explaining things in your videos. I hope you have a nice day.
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. The $TRILLIONs grid business helping.
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!
Thank you. The Powerwall will provide back up during grid outage. I’m hoping that the economics work out but it will only be viable if i can sell excess via the VPP
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
@@stevestesla9120 You are correct but the charge on excess solar only works for the car currently. Would be good if they extended it to the Powerwall. There are a few settings you can tweak but timing isn't one of them. Cheers
Not interested. they make things difficult this and that, here and there and up and down scenarios.just to take money off the people the trying to convince. what we really need is a good for everyone low priced and that's it..
I agree. I think over time we will see this play out and community power from home batteries will undercut the big generators. A few years to go though, cheers
Hi, thanks for the video very handy. I’m looking to install a 20 kW panels and about 20 kW battery. Been a Sungro battery set up so it seems I’ll need to now start researching as well electricity retailers.
Great and us renters keep getting changed more, too. And that's just for the pleasure of having electricity available, not to mention the actual cost of the electricity itself. We are all being robbed!
Unfortunately in Western Australiastan we have no option but to use the state electricity provider. Also no incentives to install bateries, it sucks that we have Labor Governments at both State and Federal level.
Off grid may make sense. On the home front. No grid electricity, savings. No gas heating and cooking and hotwater, savings. Rondo heat battery. Soon. No petroleum, savings. No cashflow to the national grid ??😊😊
you probably want to be grid connected purely for the insurance, sucks to be charged a daily rate for something you don't use but just go with the cheapest with the right battery solution software can solve the rest tbf feed in tariffs here in NSW have been rubbish for ages, you should be trying to use 100% of the battery you generate, with an EV that's pretty easy
@elduderino7767 My considered observation is that the grid itself is a $TRILLIONS infrastructure investment, and the owners, investors, and superannuation fund need the cash flow from the customer and only get the cash flow from the customer who buys enough electricity. 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. Massive savings with no more grid construction. Massive savings with no petroleum imports. Massive savings with no gas heating and cooking and hotwater use. The numbers make sense, and we should all be talking about it. Nuclear promoters ignore the big picture of more grid capacity construction. $TRILLIONS and TRILLIONS. Nuclear promoters ignore the worldwide CO2 emissions and the nuclear generation industry needs for uranium yellowcake and exploding military defence budgets.

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
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 for me. Sydney NSW. So, if you can think how the grid can keep its cash flow, you might have the grid supporting the transition to renewables. The $TRILLIONs grid business helping the transition. At the moment $kWh are increasing for the slow adopters of rooftop PV, as the grid scrambles for its cash and more rooftop is installed.
@@stephenbrickwood1602 Battery's will eventually come down in price which will increase people's independence of the grid once installed. No doubt they'll find another way of getting money from us.
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. Thanks for the videos Steve, I enjoy hearing about the various stages of your electrical journey.
Hi Martin, you’re my hero! Well done. I’ll take another look at Amber once I have the Powerwall. Are you still able to use the Tesla VPP and the facilities in the Tesla app like charge only on excess solar? Cheers
@@stevestesla9120 I was with the AGL VPP for a couple of years as Tesla's VPP came in later. I had to get disconnect from the AGL VPP to use the Amber app fully. 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. The Amber app will look ahead at forecast prices and adjust charging to get you the best value for your system.
tesla are the best when it comes to software but are they using LFP chemistry in their home batteries yet? if not i would consider something like BYD, they seem to be competitively priced and more scalable
@@stevestesla9120 took them long enough LFP is the place to be atm, sodium ion might muscle it's way in over the next 5 years when manufacturing hits scale and prices plummet - atm they are less dense than LFP but that doesn't matter too much for home storage, price and longevity is king manufacturers working with na-ion are suggesting they could surpass current density levels of LFP and even NCM with future generations, i'll believe it when i see it at any rate in sunny australia solar+batter+ev is the way forward, just need to size the solutions appropriately so you can cancel your electricity/fuel bills, high up front capital costs but you'll be ahead in a reasonable amount of time and then it's all gravy
My logic is that after 6 years I have free electricity and electric fuel for my car for the rest of my life, and then for many years later to the next owner of my house. Seems like a good deal to me, cheers
2:53 those towers have a capacity limit and so more capacity is more transmission lines. Nuclear promoters say $1,2,5,6, 10million per km to construct. And so will only build nuclear in existing fossil fueled power stations. The grid makes dirt cheap electricity expensive electricity. Just more thoughts, we should talk about the new grid costs in a central generation grid. 😮😮😮

Turn your solar panels to point at the evening sun, with a higher pitch. You’ll then be powering your home in the evenings instead of exporting mid-day. I think your battery approach is financially flawed if your peak bill is only $1.50 a night. There’s no way the savings will pay off the investment in the timeframe you suggest.
I agree with you on both points. I have to orient my solar as is to suit our body corporate. The economics only works if I can sell power via the virtual power plant as self consumption doesn’t cover it. Cheers
How often does the price go in the negative on a wholesale market? Like if you had a bunch of batteries, then got paid to store the power in the batteries, then sell it back off when the cost come back up? Or do those periods not happen all that regularly?
In SA for September, FIT was negative 46% of the time, both day and night, so practically all solar was negative FIT. We also see only an average of about 25c between cheapest buy price and highest sell price per day, which isn’t enough to pay off the battery. You can’t consume and sell your battery contents, so returns are minuscule.
I wondered the same, but my day time usage is low so i really do have 23kW/hr spare now each day and in summer that will increase. Although it will reduce probably by half in Winter. I’ll do an update in a year or so to see if I was wrong
For every EV you charge you need to add a battery of equal capacity as well as a solar array in addition to whatever you need for your house. For us that was $38,000. That is a hell of a lot of fossil fuel. The difference for us on 12 months of running a hybrid is 1800 dollars. Renewables are a con.

at any rate in sunny australia solar+batter+ev is the way forward, just need to size the solutions appropriately so you can cancel your electricity/fuel bills, high up front capital costs but you'll be ahead in a reasonable amount of time and then it's all gravy
I can't see the justification for a $17k battery...energy is going to be super cheap apparently
My logic is that after 6 years I have free electricity and electric fuel for my car for the rest of my life, and then for many years later to the next owner of my house. Seems like a good deal to me, cheers
My feed-in is 5cents kWh
My grid supply is 50cents kWh.
The grid makes dirt cheap electricity very expensive. 😮😮😮
2:53 those towers have a capacity limit and so more capacity is more transmission lines.
Nuclear promoters say $1,2,5,6, 10million per km to construct.
And so will only build nuclear in existing fossil fueled power stations.

Just more thoughts, we should talk about the new grid costs in a central generation grid. 😮😮😮

What happens when there is no sun, do we get a discount or refund. ??? The solar only works with the sun..
Did you watch the video? How do you get a drink of water when it’s not raining? Storage!
Turn your solar panels to point at the evening sun, with a higher pitch. You’ll then be powering your home in the evenings instead of exporting mid-day.
I think your battery approach is financially flawed if your peak bill is only $1.50 a night. There’s no way the savings will pay off the investment in the timeframe you suggest.
I agree with you on both points. I have to orient my solar as is to suit our body corporate. The economics only works if I can sell power via the virtual power plant as self consumption doesn’t cover it. Cheers
How often does the price go in the negative on a wholesale market?
Like if you had a bunch of batteries, then got paid to store the power in the batteries, then sell it back off when the cost come back up?
Or do those periods not happen all that regularly?
This was my experience….I switched to wholesale electricity - Amber Electric

In SA for September, FIT was negative 46% of the time, both day and night, so practically all solar was negative FIT.
We also see only an average of about 25c between cheapest buy price and highest sell price per day, which isn’t enough to pay off the battery. You can’t consume and sell your battery contents, so returns are minuscule.
What effect does installing a home solar and battery system have on your home insurance premium , given the additional fire risk ?
Zero, not an issue
@@stevestesla9120 Insurance companies will soon fix that.
You won't have that much excess to put into a battery with such a small solar PV system. I doubt your ROI battery numbers too
I wondered the same, but my day time usage is low so i really do have 23kW/hr spare now each day and in summer that will increase. Although it will reduce probably by half in Winter. I’ll do an update in a year or so to see if I was wrong
where do you get the 8 c off peak in Vic the cheapest is 20c
I don’t know is AGL available there?
😂😂😂😂 stiff, you were warned
For every EV you charge you need to add a battery of equal capacity as well as a solar array in addition to whatever you need for your house. For us that was $38,000. That is a hell of a lot of fossil fuel. The difference for us on 12 months of running a hybrid is 1800 dollars. Renewables are a con.
Hi, not sure what you mean? Do you charge a battery then dump that into your EV?
Buy a microfone!
Batteries would be hard pressed to last 6 years.
Except the latest are warranted for 10 years to still have at least 90% of their original capacity
