What will happen if 100m tall & 50m diameter water reservoirs tank installed in coastal area. A 100 kW powerfull motor installed on the top of the tank, which will pull water from sea & fill the tank & a 100 kW capacity generator/alternator will be installed at the bottom of the tank, which will generate electricity from water turbine. Excess Solar & wind energy will be stored in the tank in form of water.
@@xyz.bunny-rabbit1234 This is referred to as Pumped Hydro and happens all over the world. Some places use it to refill Hydro Dams. It is an excellent way to use excess power, maybe not the most efficient, but definitely one of the ways.
My house is 100% Electric, no gas, winter and summer plus free car charging for my BYD Dolphin, for the last 5 years, best investment ever for myself and for thenplanet
Solar on your house is a good thing. I too pay no electricity. However, the mass swindle and solar farms are detrimental to our environment. The Government is destroying our landscape and farming land for the benefit of a handful of billionaires. Swindle farms take up over 800 times more land than a nuclear plant
As a high-voltage power system engineer specialising in power system protection, the issue with an inverter generator source is that it can only generate 1.2x its max-rated output and then shut down if more power is drawn. A spinning synchronous thermal generator with heavy mechanical inertia behind it that it has can push up to 20x its nameplate rating for a moment. That 20x current for short instants is what the base protection features of the network assume is possible when applying for simple overcurrent protection. So how is the new renewable-led power system with a "lack" of inertia in each generator managed? The AER and AEMO-review system specifies that each new generator must have xxx-MW of synthetic inertia, a fault current source delivered by STATCOMs and capacitor banks. With these energy storage systems, the fault level from each generator point of connection and the multiple inverters from each string/turbine gives a short-time "fault ride-through" capability. So, while an individual inverter might not have enough power to supply an unstable system, each generator, as a conglomerate, does. Each individual generator needs a stable transmission grid to supply its full output power. Now, generators are easier to build under their planning permits than upgrades and established transmission lines. So, the transmission infrastructure needs to catch up. The nature of where the sun shines, and the wind blows differs from the millions-year-old seabed basins where coal deposits formed, so the old transmission capacity needs to be in suitable locations. The power industry, having not run new transmission lines for over four decades, trying to build new transmission lines to forty-year-old social licences has led to an alienisation of the communities and a black-and-white argument of NIMBY'ism vs Free-Speech tit for tat. The transmission is needed. There has to be copper connecting more parts of the state to the load centres. However, how it's done and giving the individuals and communities impacted compensation and a say in how it's done is a piece that needs to be discovered. Asking those communities to have a hand in deciding which properties and geology can handle the lines, what tower styles (less-visible tall monopoles vs squat wide low structures that impact aeroplane-agriculture less?) suit the farming or tourism practices of the community, and what supports a strong economy for the local towns and businesses need to be quantified. This is the issue we have. Generator developers are crying poor. But they knew the risks. They knew the constraints. They knew they were developing new wind and solar farms, so another developer didn't get access rights on a transmission line before them, even though it would impact the curtailment of their previous project. Based on their risk budget, they can ride through the lack of transmission for another couple of years. Or augment their installation with a battery system that absorbs peak energy at their curtailed price (zero dollars) and then pushes it out on the transmission line when it's at capacity. If it's got capacity, then it's probably when no wind and solar farms are generating, and the spot price is high. The issue is that these developers are the same ones that back political causes and have media departments, so they lobby public opinion away from these four simple concepts. Obfuscating the issues and polarising opinion against the simple outcomes. The power industry is too siloed, and Electrical Engineers are too hidden from the public because their management thinks they are not people people. There are no holistic engineers with an understanding of public opinion. They are used to dealing with invisible quantities like electrons and impedance, not their neighbour's opinion that their views are more critical than your powerline. A few of us are used to doing human factors studies, architectural designs worth as much to the power project as the electrical design, and putting assets in full view of a few thousand people per day at, for instance, a local train station. The solution to Australia's power network is more of what we are doing. as it's cheap and fast. But linking it all together without further alienisation of the communities it passes? It could fail. But it's not for the reason you say.
I have been on 100% solar now for 7 years. I disconnected from grid 4 years ago after achieving great success in the parallel run testing and achieving very high average State of charge for the battery system even under the most challenging winter periods. Winter is the most challenging times for true Offgrid solar. Not only we need to oversize the solar panels, oversize the battery capacity, but more importantly is to increase high current handling capabilities, optimise solar panel tilt angles to achieve high performance for both winter and summer sun. The key towards high optimisation is to group the panels into subgroups and each having dedicated solar controller to track the maximum power yield as possible. My current set up is based around the Victron Lynx 1000A busbar system. 3x Lynx Power In modules for input and 1x Lynx Power In module for battery output. Each Power In module is modified to accept fuse like the Lynx Power distributor does on all 4x set of connectors. The 4x terminals on the Lynx Battery connection are connected to 4x independent battery banks, each having their dedicated 500A custom flexible busbar and 400A Industrial dual pole DC breaker with remote disconnect and 400A Bluetooth enabled power meter w/ hall effect sensor, 4x to 6x 120Ah LFP connected to each of the 500A busbar, with each LFP having independent BMS capable of supporting 100A charging and 150A sustained discharge. This ensures each of the 4x battery subsystem is more than capable of accepting 400A charging and 500A discharging. They combined to provide a whopping 1600A charging and 2000A discharging capability, which is currently limited by Lynx 1000A busbar and can be expanded if required. On the solar charging end, the system has 6x 100/50 SmartSolar + 2x 150/100 SmartSolar. These 8x solar controllers are connected to 16x Sunpower Maxeon 3 400W panels in various groupings. Two or three SmartSolar solar controllers are mounted on three modular portable units, each having independent portable aluminium space frame + handle construction, which doubles as passive heat sink, utilising cutting edge ultra high thermal conductivity multi-point Indium metal + thermal pad + thermal paste contacts to the Victron heat sink to ensure the best thermal transfer possible. The set up typically now runs very close to ambient temperature. On very warm days under max load they run around +2C above ambient temperature. The Blue Victron controller surface runs cool even under max load. Each modules is portable and can be easily detached from the main system and be redeployed in camping or caravaning scenarios to support extra Offgrid solar applications. The aluminium frame is further augmented with rows of additional copper sinks with fins to improve the heat dissapation. Very useful for the extra warmth we can expect in Australian summer conditions. In additional to passive cooling there is also active cooling, supported by a real time thermal sensor and temperature monitoring system with temperature display and a Noctua cooling fan with variable fan speed modulated by a fan controller according to the temperature difference and cooling required. The forced air induction shares the same common convection cooling air chamber as the Victron heat sink and the copper heat sink w/ cooling fins. The natural heating nature of the Victron heat sink initiates the convection air flow. Each portable module features its own DC breaker for solar and battery. And the battery connection is achieved via a 300A flexible busbar system (with the same multi level staggered design as the Lynx, with independent fuse for each of the 4x sets of connectors) to achieve a dual 175A Anderson connection to the Victron Lynx 1000A, when the module docks back to the main system. This is a self load balancing and fault tolerance design. Should any issue develop on one connection that raises its internal resistance, the current would be automatically be shunt to the other working conductor. The system is fully capable of running on just one 175A Anderson connection. There is plenty of built-in headroom for extra safety. Solar panel connection is done via 125A Anderson plugs. As we have encountered unreliable situations where the 50A Anderson has failed due to the insufficient spring pressure on the silver coated connectors, causing heat generation and the housing to fused together. We saw this twice already. So we ditched all 50A Andersons and have no problems with the 125A Andersons. All the solar cables and battery cables are over sized to ensure they run stone cold. Cerbo GX acts as central control. It is further augmented with Node Red, providing 24x7 monitoring all SmartSolar to detect and remedy sleepy controllers, whereby in the morning the PV voltage exceeds a certain threshold and the controller is enabled but it has not started changing. So far we only see this issue with the 100/50 randomly. Likely a firmware issue. When Node Red detects this scenario it will issue a controller restart and the issue will go away. There are also BMV712 on one of the battery subsystem together with Victron smart voltage sensors, in addition to the Lynx Shunt. This provides at least 3 different backup references on power meter as well as temperature and voltage feedback. We achieve high redundancy and uses multiple references to detect any potential issues, should any sensor fail. We run weekly FLIR thermo imaging to check for any potential hot spots. Glad to report we managed to achieve a higher than 95% during winter periods in achieving 100% state of charge with battery, even under the worst rainy and cloudy days. On the rare days that the system just falls short of hitting 100%, 99% of the time it hits this goal the subsequent day. Our battery system constantly cycles between 88% to 100% on most days during winter., maintaining a very high average SoC.
Big mistake with the transmission lines being redundant. They will be more important than ever and more interconnections are needed. Especially long distance ones.
It's true, that a single family home has enough area on the roof to be fully self-sufficient on solar energy. but industrial sites use more power than can be collected from a roof-top solar array, even with the most efficient panels available today. The grid as a whole will remain a necessity for industry and infrastructure for quite some time. According to the IEA, homes are ~37% of total electrical consumption world wide. As more and more people adopt solar, that load will be replaced by more businesses, as economies grow. If anything, that will prolong the market life of the grid, with minimal investment in new infrastructure. The best solution for back-feed tariffs, is behind the meter batteries. Even without solar, batteries can be used for "arbitrage". That's where the batteries are charged when there's little demand on the grid, and power is cheap, then, used during peak hours, when electricity is more expensive. A charge controller with a threshold cutoff can be used, to do this autonomously. At mid noon, when all the grid-tied solar is at its peak, the voltage rises, and the charger can draw from the grid to supply the home, as well as charge the battery. In the evening, the sun sets, solar power tapers off, and all the air-conditioning systems are running at their maximum, the grid voltage drops. The controller simply quits drawing from the grid, while the home continues to run off its battery. Wide spread use of such systems will stabilize the grid, allowing much more customer demand, without any upgrades to the infrastructure. This exact concept is perfect for public DC fast charging stations, for electric vehicles.
Lets be honest, Power companies in Australia thought it would be a great idea to buy power at a stupidly low rate of 6 cents a Kwh and sell it back to us at 40 cents a Kwh, however now they are getting too much power they want to charge us for giving them discount power... lol and we as a citizens buy into that and don't say a thing, the world would be so much better if we the people woke up stopped these companies from doing these types things
ERROR at 7:14 *_"... to provide 150 megawatts or 195 megawatts per hour ..."_* First of all, you need to understand that Watts are a measure of power, while Watt-Hours are a measure of energy. What's the distinction? Power is the amount of energy delivered *per unit of time.* Conversely, energy is the total amount of energy delivered, which is equivalent to *multiplying* power (Watts) by the time. In other words, power is the rate at which energy is delivered, while energy is the accumulation of power delivery over time. My guess about the numbers you read is that perhaps this storage installation can deliver a maximum of 150 megawatts (peak, instantaneous power), and has a capacity of 195 megawatt-hours (NOT megawatts *_per_* hour; rather megawatts *_times_* hours). Megawatt-hours is a unit of energy, expressed as a *multiplication* of watts and hours; this is example, 195 megawatt-hours could mean a 1 megawatt of continuous power delivery for 195 hours, or 10 megawatts for 19.5 hours, or 100 megawatts of power delivery for slightly less than two hours. The megawatts and the hours, in each case, multiply to 195. "Megawatts *_per_* hour," or any expression of power *_per_* unit of time, is a nonsensical, made-up unit, unless ... Well, it could only make sense in the context of expressing a speed of reaction by a power generator, namely how many milliseconds it takes to go from zero output (quiescent) to outputting, say, 100 Megawatts. If it took about 31 minutes to do so, that would work out to 195 megawatts *_per_* hour, but it would be terribly slow. Tesla's mega-packs take milliseconds (I even heard MICRO-seconds, but have a hard time believing it). At 100 milliseconds for 0 to 100 megawatts, you'd be talking about a power reaction time of a gigawatt per second, and that would be slow; so my guess about Tesla's mega-pack in Australia is that it would feature anywhere from 10 to 100 gigawatts-per-second velocity of power output adjustment; not megawats-per-hour. A channel with the word "Engineering" in its name should not make such atrocious errors in its reporting. If you guys are NOT engineers, yourselves, that is okay, but then you MUST obtain the help of an engineer or two, to proofread your scripts. Just my 2 cents.
Yet a correspondent above, @TimLeech1337 who claims to be an Electrical Engineer says that the problem with battery inertia devices is that they are limited to 1.2 times their rated load before they shut down, whereas spinning turbines can be over stressed 20 times for a short time to provide real support for fault current loads that supports system stability. Maybe physics calculations are not sufficient to run the grid, we need practical qualified engineers? I am an interested engineer too, but I am not a grid operator.
The unit is watthour, no hyphen needed. Megawatts-per-hour is not a thing, it is just megawatthour. It would be better to use the unit "joule" which is the proper unit of energy, as 1 watt is 1 joule per second, and clearly shows that a watt is a rate of flow of energy. Therefore 1 watthour = 3600 joules. 1kWh = 3.6MJ. These are quantities that can be visualized like marbles or water in a bucket, which is what a battery is for electron potential. These things aren't difficult to grasp, they are just not taught properly, and not used properly, so continue to perpetuate.
I have rooftop solar and batteries but still connected to the grid for those really overcast days. I'm around 90-95% self sufficient year round thanks to our location in the tropics. It works great and if you live in a reasonably sunny part of the world, solar with lithium battery storage is the way to go.
I am the same, but due to the stupid costs in NSW for electricity and supply, I am about to disconnect from the Grid. We have had the grid physically switched off for the last couple of months already. At zero electricity used from the Grid, it costs me just under $170, - a quarter for....nothing.
We have something similar in UK but def need the link with grid as there’s no way we can get enough solar all year round we’d need to massively over egg the solar system to be able to get enough over winter! But we get a good ‘chunk’ over summer we also get most of our hot water from early to mid spring to mid end autumn from solar thermal (def a better version of solar for uk than the solar pv, we only have the pv due to overly good subsidy)
Batteries are TOO DUCKING expensive in Australia. Why on earth would anyone pay the electric company to send their own home solar electricity into the GRID? It makes absolutely no DUCKING sense.
too many people have bought panels only to discover that they turn off during a blackout, having been misled into believing they'd still have power, and finding out the hard way that "oh, haha, no, you needed to buy the much more expensive system if you wanted that", too many people have been scammed by door-to-door solar panel salespeople selling crap panels at a huge markup. too many people have bought EVs and found that using a charging station at 60c per kwh costs the same per km as petrol, and if they want to charge at home they've gotta buy a special charger and pay an electrician to connect it, which means it takes YEARS for the savings to make the initial costs worth it, and the electricity to charge the car comes from coal anyway because they're charging at night. government policies regarding feed-in-tarrifs have destroyed all investment prospects, why buy panels that produce energy at home when you're at work and can't use the energy at home, and won't even get any money for the power you can't use? if you're gonna get a solar + battery setup why bother staying connected to the grid if the power you're selling won't even cover the service fee? the green revolution is dead, killed by government incompetence and dodgy companies ripping off customers. instead of panels on workplaces and carparks (where power actually gets used during the day) we've got panels on farmland and on homes that are empty during the day, not because there is anything wrong with the technology, the technology is great, but the people selling it are con-artists with no "higher goal" than lining their own pockets.
These are the issues I face in New South Wales with solar power into the grid, (1) a corrupt political party sold off the network, all power generation & distribution went from government owned & operated to private or foreign asian governments control, (2) with solar generated into the grid I receive 7 cents per kWh, but when I buy power from the grid it cost me 46 cents per kWh, (3) I will be fined 1.2 cents per kWh for over supply into the grid between 10am to 3pm, What a joke, (4) I will now have to consume all the power my solar panels generate during this time or turn them off, or buy a $10,000 battery plus installation, (thats money I don't have) to soak up my over supply. Now here what would have happened if the power network was still owned by government, we would have been paid x cents per kWh from my solar panels, the government would have installed batteries at locations around the state, as they phased out the coal fired power stations, in turn at night I would have purchased the power from this battery supply at the same rate OR 2 cents more to pay for the battery installation. As the power grid on the east coast of Australia is now owned by money demanding foreign owned companies who are in most cases owned by asian governments, we are being treated as mugs, conned into spending thousands of dollars to fit solar panels, & now being fined for the right to generate power, while oversea's countries make money (profits) at our expense, in fact most of the solar panels installed are made in these asian countries as well, ITS TIME TO NATIONALISE THE POWER GRID under Federal Government control & export these foreign government companies out of the country.
@tilapiadave3234 he buys at 46cents because he does not have a battery. Plus $1 daily connection fee. With V2G and 2nd hand BV then all electric offgrid will screw grid cashflow. The grid is a $TRILLIONS infrastructure investment that needs cashflow, $100sBILLIONS cashflow every year. BVs will allow more offgrid time for grid customers. No grid cashflow when the sunshines. No grid cashflow when the battery oversized battery supplies after sun down. Rooftop PV panels shading hot roofs. 😊 Happy days.
@@stephenbrickwood1602 Why would he CHOOSE to pay 46 cents ,, take a flat rate of 27 cents is surely better. It has nothing to do with having a battery or not ,, or having solar panels or not , you still need to select a suitable plan
@@tilapiadave3234 I am stuck with the 50cents kWh supply because of daily connection fee and $kWh rates. So that is my Sydney reality, fantasies are lovely for others.
For your average house in NSW without a pool, even with our insane energy prices, it still takes around 10 years to recoup the upfront cost of a battery. Until they half in price, they are still a perk for the rich
I think the best plan with solar is installing the panels and batteries in households. Most households have enough space for batteries to make them self-sufficient, and using rooftop space would be better thna clearing hectares of land
Home owners can make long investment decisions into solar power to reduce costs but the grid operators can change the rules at the "drop of a hat “whenever they want to ensure they don’t have to spend make investments or reduce profits . All the while ably assisted by the compliant government and regulators. Capitalism with state support whenever profits or dividends are threatened - it’s a mad, mad world.
Here in Queensland Australia the lower socioeconomic suburbs were the biggest adopters of solar, it wasn't until the demand of new homes having to have solar from construction that we saw better off areas fill their roof space with panels, people with money don't care about cost of power as they aren't financially susceptible to price fluctuations.
Steven Greer has spoken about many times the problems with solar. On his farm in Virginia, he installed the largest legally allowed in the state solar farm. Any bigger, they would need to be a commercial operator. So his solar farm is big. It cost over 80 thousand dollars when they installed it. Over the winter, they have heavy wet snow fall. One particularly year, the snow took down millions of trees, and left many without power for a week. That huge system on Greer's farm would not even heat his house for an hour. They had hot water, lights & the fridge running from it all but that was it. The energy density is simply not there meaning energy density the amount of power for that size and expense isn't going to run planet earth with 8 billion people. Solar technology is too little too late. Considering we have zero point energy technology & have had since the 50's but they suppress it all, puts things into perspective that with this solar product, they are trying to sell you alternative crap that simply doesn't work.
There are other very practical ways to use the excess. Place atmospheric water generators on city center roofs and running them on some of the excess will produce water for drinking, etc. and also will reduce relative humidity which will make summer (when there is excess solar) heat more bearable to people and animals. Through evaporation forests and other ways, the sequestered water can be used to cool hot zones through evaporative cooling (when humidity is low enough. Cycle is infinite.
Wrong. You cannot go off grid unless you oversize your solar array to compensate for the fact that you produce half the energy, on your shortest day, of the energy you produce on your longest day. That means doubling or tripping your solar and or your battery to keep the lights on while off grid. The solution to too much solar isn't just batteries. It's diversity including wind and geothermal. Pumped hydro storage is more sustainable than lithium battery arrarys, and Australia could and should utilize sea water so that it is reliably sourced.. Elon Musk implanted the wrong tech, because when you're a hammer, every problem is a nail.
Australia is the global leader in percentage of population who has solar. The problem is we have too much solar in relation to not enough storage. Vivid sugar is even in out of the amount of. the amount of electricity because the most electricity will be in the middle of the day when everyone's working and not home So you need to store that somehow. this way this little the world's largest battery pack. was such a success. Almost immediately after being stored. there was an outage somewhere in the system in Victoria and the battery kicked in in under a second to stop any rolling blackouts and supply energy to the sector that didn't have it. We need to start using up a forms of storing energy, like pumped hydro.
One idea for those that are off-grid. If you are a bit short on stored watts, just take your EV to the nearest charging station and bring those watts home.
@@JUDITHBEARD-v3f Depends upon the capacity of your off grid energy system and your driving habits. The most likely case is an unusual period of low system input. If your normal daily driving habits only use part of your EV's charge, then it should not be problem. It would be an interesting strategy to downsize the home energy system and depend more on the EV battery.
My house is 100% solar but have to get a battery now the government wants to charge us for feeding into the grid as it apparently can’t handle it from everyone’s solar
Because the fossil fuel industry wants to delay the inevitable as long as possible. Nuclear is a divide and obfuscate issue. If they can delay the switch by years before admitting nuclear doesn't make sense, they have kept us buying their products.
Delaying the phase out of fossil carbon, by fear, uncertainty and doubt (FUD). That's how you kill investment in energy, locking in the status quo for as long as possible.
@@tilapiadave3234 perhaps in a country with a mature nuclear industry. Not in a country without one that has to have significant legislative change to even begin.
Energy is wealth in our society. Our rise as an industrial society and our massive population growth are directly tied to our exploitation of energy from waterwheels and windmills and then whale oil and coal, and then hydroelectricity, petroleum and nuclear, and now modern wind, solar, and batteries. Because energy is wealth, Australians will find a way to profitably store or use the surplus, refining minerals, whatever.
It's not off grid the power companies want. They want people to have batteries to store power for usage in times of power outages or black outs. If people go for off grid power usage then that cuts the power supply companies out of the equation which the companies naturally don't want to happen.
The larger solar panels are much more affordable in context as shingles creating a 30 year roof, or sundeck above roof, I am hoping to use such a system using a welded and epoxy coated U channel or H channel to support and act as rain gutters and walking channels . Here in Mexico with 100" rain a year and enough sun for a 4 year payback .
The problem is the NSW state government sold off the “poles and wires” to a Chinese company, yet to take in the solar infeed requires a huge investment in this now private network. So who will pay?
Because of vested coal mining interests and politics. And the interior of Australia is nothing like the interior of America or Europe. Tough old country with extremely low population density and infrastructure.
Yet electricity gets more and more eXpensive... 😥 Off grid sounds like best option. 👍 Edit : Australian Government needs to BUY BACK the grid infastructure, that it sold off in the first place......
Off grid is not so easy in the northern hemisphere. My solar output in the winter is about 1/10 of that in the summer while I mostly need that power in the winter. With a battery I could use cheap night power to charge the battery and use that on cloudy days but the price has to come down by about half for it to make sense for me. Sounds like in Australia it is easier to go off grid. Maybe I will move there ;-)
If you have the time. To do it yourself it is 100% possible for the poor as I am. I have 3200 watts in panels, 3000 watt all in one invertor, and 24kwh. Total cost is 7 grand. When we expand to take on 90% of the house it will be even cheaper.
Solar panels are so cheap now there is no barrier. There are large panels going for $25-$30 EASY. They are almost giving tons of them away. Inverters are inexpensive for the most part. Even the price of battery storage has plummeted. The top name brand batteries are still expensive but the DIY and lesser known brand batteries are super cheap compared to just a few years ago.
@@pdipatria In Germany we have "balcony solar panels" + Batteries. Just buy a set, attach them to you balcony or anywhere else there is space or talk to te landlord etc. This already makes a great difference
Home and small business-scale batteries need to drop dramatically in price. Home-scale battery storage currently has an installed price of over $10,000 per kilowatt hour. Electricity is typically generated and transmitted by greedy, price gouging and corrupt monopolies and cartels. That price needs to drop by 80% or more to really disrupt the cartels.
Those are premium battery storage companies. I just built a 14.1 kwh battery for under 2 grand. At that rate I could build 6-8 14.1kwh batteries for the price of 10 grand.
The weak link in domestic solar is the storage. Batteries go belly up all to soon and replacement is expensive,robbing the system of a lot of efficiency. So a storage device/system that is entirely mechanical. Envision if you will a seriously heavy pod (broken glass, lead,maybe even steel being winched up all day long and ready to release its stored kinetic energy in an instant. Only maintenance would be a cable replacement once in a blue moon. When I have the dollars I will be building mine.
Charging for exporting power during middle of day is quite the stab in the back. The temporary solution for home owners is to get a battery for home. The permanent solution is to get a BIGGER battery and say goodbye to the grid connection. Justice finally after years of us all being slaves to energy companies. 20KwH battery installed for $13K total.
If all of the energy produced by renewables was dedicated to producing even more renewables, then renewables would become exponentially self-reproducing to a maximum limit, at which point almost all of the energy they produce would become free energy.
Misleading heading as it was just a plug for the solar industry that highlighted the good aspects but totally ignored the pitfalls and true costs. It especially mislead regarding batteries and glossed over the economics of running such a system. This is a particular issue for the growing higher density housing in cities and the need to have a grid and 24 hour power source for those cities. Like so much of this propaganda, it fits well for affluent people with larger single dwellings that can carry sufficient panels to generate meaningfull amounts of electricity to tide over nights and poor weather days as well as the wealth to afford the cost of storage. These costs are still well above the break even point over the life of the product. Add to that, the rest of the population that doesn't fit that demographic and the propsal fall flat as you still need to generate stable power for them, for industry and the like. Solar is a nice addition for some but not a solution for all.
Farcical short term planning, nothing lasting more than a few decades, while base resources are finite. Plus a massive toxic recycling problem. All after the IPCC stated with absolute clarity in AR6 that there is no climate crisis. Industry loss due to poor quality 3 phase. These people couldn't plan a beer in a brewery.

Lol! Tesla 15kwh powerwall for over 10'000 dollars? I just installed a 35kwh powerwall using 2 batteries with JKBMS for 120'000 THB (around 3'000 dollars).
Remember folks, fossil fuel is both energy dense (so compact), and its a built in battery as its stable until used. You would think a great solution would be to make synthetic hydrocarbons from solar power and then burn them when needed. Yah, not a new idea. But endless free power from solar must be matched with really good battery storage to just end oil.
With a population of only around 26 million, Australia is a relatively small market for major exporter countries like China. And with huge natural resources, it should not be that difficult for their government to take good care of their small population.

Grids are super expensive and unreliable. Best solution is for everyone to have their own batteries and download power when convenient or better get their power from the sub
@@allangraham970 it is not economical only use batteries as storage. My house (middle of Europe) hold uses 3 times of energy in winter that the PV system produces. In summer it is the opposite. With wind energy can help and that needs a powerful grid
Actually the lithium phosphate batteries are going past 10 years without losing hardly any efficiency. Most of them are lasting 15 years before they need to be replaced. When they fail though, they just die instantly and don’t work anymore. You’re right about the expense though, a whole home battery bank will double the cost of your solar install.
It's about the power companies ability to manipulate the prices per kwh. And keep it within a price range they can profit from.. Prices should fall but they won't .
Battery draw power from the panels not panels push power. BMS can control its input.

off the grid is not possible, government is not ready to let population free. Plus the infrastructures CAPEX need to be from the governments so that they can get cheaper money loans. Otherwise the cost of energy will skyrocket
Solar is awesome. I do various experiments with solar panels living off-grid in the Mojave Desert. My newest endeavor is storing heat in sand. Directly wired to the solar panels. Using a step down or step up DC to DC power converter you can run all sorts of electronic products like radios televisions on and on. It's a lot of fun experimenting with solar.
There is no such thing as "too much power" it is always too high pricing. There is always a market clearing price. There will always be more customers, such as AI and digital currency customers. Is it possible that the utilities are too stodgy to lower prices and find new customers at the lower price?
Does this bloke know what he is talking about?? At the 7'18" mark "to provide 150 megawatts or 195 megawatts per hour (sic)". I do wish these people who purport to know a bit about their subject matter, could actually demonstrate same!
Pulse we must look at the total problem. Millions and millions of customers and millions of miles of national grid. And generators. The key is the grid being a $TRILLIONS infrastructure investment and ROI,return on investment, to the grid owners. $100sBILLIONS in cashflow. It turns out that the customers cashflow is critical to the grid. With millions of V2G BVs oversized battery parked 23hrs every day and all night long and rooftop PV then customers cashflow could stop the grids cashflow when the sunshines. This is utter death to the national electrical grid, the $TRILLIONS and $TRILLIONS infrastructure investment with superannuation funds and government and othe investors suffering. Too many talk about the central generator and ignore the millions and millions of customers who must stay on the grid and with their BV's and rooftop PV, if ignored can go OFFGRID. OFFGRID can destroy the national electrical grid infrastructure. This would be an utter waste of the national grid. The grid was built over 100years, 10 decades, with billions of tonnes of resources and massive financing. Too millions and millions of customers homes and buildings and industries. No CO2 emissions and clean electricity and new economies in a warming world it is this big picture and direction that is important
A charge tax for doing what is good for the environment? Sheeeeeet. I would invest in more batteries for my properties so that I can disconnect from the grid and all that bs.
Most vehicles drive building to building. Most vehicles are parked 23hrs every day. Most BVs oversized battery can be topped up daily on trickle currents. V2G selfparking selfplug-in BVs will be able to bumper plug-in to a $60 wall outlet at every buildings carpark space, ezi pezi. Trickle currents all day long and all night long ezi pezi. Rooftop PV panels shade hot rooftops all day long in warming latitudes. What could be better ??
This is not engineering its nonsense. Solar voltaic electricity generation if not being used to charge storage is nearly worthless. One large cloud passing over a solar farm causes its output to drastically falloff requiring instant makeup typically supplied by natural gas turbines running at at high availability service idle. Running at service idle uses about 70% of the fuel as full throttle, but produces little useable power. This is the cost of high availability. Old coal fired power plants were not made to supply instant makeup nor were old nuclear plants. Hydro power does this well. The public power grid makes it own electric power much cheaper than the forced buy of solar voltaic power that is erratic and has to be conditioned. The public power grid can't refuse to buy the peaks of solar voltaic generated electric power. In the case of over supply of solar voltaic electricity the public power grid has to spend money to start and run natural gas turbines at high availability to offset any dips in output just to sell power at low cost to other power grids to get rid of it. These forced buys of erratic power to the public power grid costs the average rate payer a lot of money. Instead of passing all these costs on to the rate payer most of the public power grids forced to take on these at high costs forced erratic power purchases forgo improvements and maintenance to the power grid making it more prone to black outs. Tesla doesn't want to sell its solar roofs without it being a part of their power wall battery storage. That isn't just to sell more product, its because Tesla thinks big and doesn't want 10,000 of their solar roofs to be an icon of distribution to the public power gird. The battery electric power storage allows Tesla to network the power walls together to sell contractable peak power or emergency power to the public power grid. This is contractable power for a set fee for a set time at grid quality. In the video using Australian dollars that are about 2/3 the worth of the USD and the Euro making relative amounts 50% higher the cost per kW/h of home battery storage was at nearly $10,000 Australian. That's extremely high when car batteries in 2023 world wide were averaging at $139 (USD) per kWh. It's stressful and less efficient to discharge batteries quickly even with chemistries designed to be good at it. It is not really discussed what is a reasonable discharge rate, but 4 hours from 90% to 20% SOC for lithium ion daily use is likely reasonable for power grid use. The batteries will probably last less than ten years. When looking at a power grid battery supply it can likely provide 1/4 of its rated capacity per hour with the ability to provide high peaks. So 100 MWh battery could provide 400 MW for five minutes or even a GW for a minute, but for daily service likely should not be pushed past supplying an average of 25 MW/h. 100 MWh battery would be the same battery capacity of 123 Tesla Model Y with 81 kWh battery pack. One natural gas fired GE 7EA turbine can make 90 MW in simple non steam cycle www.gevernova.com/gas-power/products/gas-turbines/7e. Its very compact fitting into the space of a city bus and they typically last 100,000 - 150,000 hours with their being 8760 hours in a regular year that is over ten years of nearly continues service with some shutdowns for inspections before the rotor it considered at the end of its service life. It can run largely unattended. It is the low capital cost, high ease of situating, naturally very low emissions, low maintenance, low staffing cost, fast start up and their ability to follow large changes in power requirements quickly that makes gas turbine generators very attractive for generating peaking loads. Their fueling costs are high. A modern ultra supercritical coal plant should have fueling costs at 1/3 to 1/4 the cost of natural gas turbine combined cycle generator. Much of the time the steam cycle in a NG combined cycle plant that adds a big jump in efficiency comes in too late to be highly useful. It scientifically impossible, that is with all the science we have today without new science, for greenhouse gas behavior to cause global warming. All the greenhouse radiant energy from the earth is completely absorbed in earth's greenhouse effect within 20 meters of the radiating surface by greenhouse gases which would be the same if the strong greenhouse water vapor were the only greenhouse gas in the atmosphere. Water vapor varies hugely across the earth's surface. Most of the time except in the driest deserts all the greenhouse radiant energy is completely absorbed in much less distance than 20 meters from the radiating surface.
Did you base your finding in North America, because most of the sola farms in Australia are in the sunnier parts of Australia which has few cloudy days and before sola farms came along, small communities were using diesel generation. People who live in remote locations like sola generation because they do not have to breathe in diesel fumes. People who have sola on their roof in larger communities are encouraged to use the power they generate themselves, by using it to heat water, cool or heat their homes, store the power and so on.
If solar panels work of heat and light could you not build a box or unit and light a fire inside?or use a electric heater on a circuit or a low watt high light Florence bulb..
With your massive dependence on China on both the demand and supply side you won't have a problem because China will "take care" of it for you. I saw your solar panel import numbers, for instance, and it is truly shocking. Also your exports, which are largely minerals, are so heavily skewed towards China. And now if you don't have good relations with your #1 trading partner, what can possibly go wrong??
they aren't lead-acid batterys now, there are already batteries that will last for 20+ years in cars, and stationary batteries will last even longer. But don't spend your money if you like paying increasing power bills.
Well the bills haven't gotten any cheaper so people are going to keep getting solo like I'm going to do and I'm going to not feed any solar to the grid so I can get a bigger system with batteries and pretty much be off grid that's why people get solder to go off grid

But everything that makes that possible is run by oil and poor miners. Ponder that.
As a high-voltage power system engineer specialising in power system protection, the issue with an inverter generator source is that it can only generate 1.2x its max-rated output and then shut down if more power is drawn. A spinning synchronous thermal generator with heavy mechanical inertia behind it that it has can push up to 20x its nameplate rating for a moment. That 20x current for short instants is what the base protection features of the network assume is possible when applying for simple overcurrent protection.
So how is the new renewable-led power system with a "lack" of inertia in each generator managed? The AER and AEMO-review system specifies that each new generator must have xxx-MW of synthetic inertia, a fault current source delivered by STATCOMs and capacitor banks. With these energy storage systems, the fault level from each generator point of connection and the multiple inverters from each string/turbine gives a short-time "fault ride-through" capability. So, while an individual inverter might not have enough power to supply an unstable system, each generator, as a conglomerate, does.
Each individual generator needs a stable transmission grid to supply its full output power. Now, generators are easier to build under their planning permits than upgrades and established transmission lines. So, the transmission infrastructure needs to catch up. The nature of where the sun shines, and the wind blows differs from the millions-year-old seabed basins where coal deposits formed, so the old transmission capacity needs to be in suitable locations. The power industry, having not run new transmission lines for over four decades, trying to build new transmission lines to forty-year-old social licences has led to an alienisation of the communities and a black-and-white argument of NIMBY'ism vs Free-Speech tit for tat. The transmission is needed. There has to be copper connecting more parts of the state to the load centres. However, how it's done and giving the individuals and communities impacted compensation and a say in how it's done is a piece that needs to be discovered. Asking those communities to have a hand in deciding which properties and geology can handle the lines, what tower styles (less-visible tall monopoles vs squat wide low structures that impact aeroplane-agriculture less?) suit the farming or tourism practices of the community, and what supports a strong economy for the local towns and businesses need to be quantified. This is the issue we have.
Generator developers are crying poor. But they knew the risks. They knew the constraints. They knew they were developing new wind and solar farms, so another developer didn't get access rights on a transmission line before them, even though it would impact the curtailment of their previous project. Based on their risk budget, they can ride through the lack of transmission for another couple of years. Or augment their installation with a battery system that absorbs peak energy at their curtailed price (zero dollars) and then pushes it out on the transmission line when it's at capacity. If it's got capacity, then it's probably when no wind and solar farms are generating, and the spot price is high. The issue is that these developers are the same ones that back political causes and have media departments, so they lobby public opinion away from these four simple concepts. Obfuscating the issues and polarising opinion against the simple outcomes.
The power industry is too siloed, and Electrical Engineers are too hidden from the public because their management thinks they are not people people. There are no holistic engineers with an understanding of public opinion. They are used to dealing with invisible quantities like electrons and impedance, not their neighbour's opinion that their views are more critical than your powerline. A few of us are used to doing human factors studies, architectural designs worth as much to the power project as the electrical design, and putting assets in full view of a few thousand people per day at, for instance, a local train station. The solution to Australia's power network is more of what we are doing. as it's cheap and fast. But linking it all together without further alienisation of the communities it passes? It could fail. But it's not for the reason you say.
Well said, with that much input the information and views should be shared with the towns that are affected. Well said!

100% of my electricity form Solar for 7 years
Tell us more, tell us your specs… in the next 3yrs I want to be off grid. Please tell your experience since people don’t want to tell their truth!!!.
100% for 12 years
I have been on 100% solar now for 7 years. I disconnected from grid 4 years ago after achieving great success in the parallel run testing and achieving very high average State of charge for the battery system even under the most challenging winter periods.
Winter is the most challenging times for true Offgrid solar. Not only we need to oversize the solar panels, oversize the battery capacity, but more importantly is to increase high current handling capabilities, optimise solar panel tilt angles to achieve high performance for both winter and summer sun.
The key towards high optimisation is to group the panels into subgroups and each having dedicated solar controller to track the maximum power yield as possible.
My current set up is based around the Victron Lynx 1000A busbar system. 3x Lynx Power In modules for input and 1x Lynx Power In module for battery output.
Each Power In module is modified to accept fuse like the Lynx Power distributor does on all 4x set of connectors.
The 4x terminals on the Lynx Battery connection are connected to 4x independent battery banks, each having their dedicated 500A custom flexible busbar and 400A Industrial dual pole DC breaker with remote disconnect and 400A Bluetooth enabled power meter w/ hall effect sensor, 4x to 6x 120Ah LFP connected to each of the 500A busbar, with each LFP having independent BMS capable of supporting 100A charging and 150A sustained discharge. This ensures each of the 4x battery subsystem is more than capable of accepting 400A charging and 500A discharging. They combined to provide a whopping 1600A charging and 2000A discharging capability, which is currently limited by Lynx 1000A busbar and can be expanded if required.
On the solar charging end, the system has 6x 100/50 SmartSolar + 2x 150/100 SmartSolar. These 8x solar controllers are connected to 16x Sunpower Maxeon 3 400W panels in various groupings. Two or three SmartSolar solar controllers are mounted on three modular portable units, each having independent portable aluminium space frame + handle construction, which doubles as passive heat sink, utilising cutting edge ultra high thermal conductivity multi-point Indium metal + thermal pad + thermal paste contacts to the Victron heat sink to ensure the best thermal transfer possible. The set up typically now runs very close to ambient temperature. On very warm days under max load they run around +2C above ambient temperature. The Blue Victron controller surface runs cool even under max load.
Each modules is portable and can be easily detached from the main system and be redeployed in camping or caravaning scenarios to support extra Offgrid solar applications.
The aluminium frame is further augmented with rows of additional copper sinks with fins to improve the heat dissapation. Very useful for the extra warmth we can expect in Australian summer conditions. In additional to passive cooling there is also active cooling, supported by a real time thermal sensor and temperature monitoring system with temperature display and a Noctua cooling fan with variable fan speed modulated by a fan controller according to the temperature difference and cooling required. The forced air induction shares the same common convection cooling air chamber as the Victron heat sink and the copper heat sink w/ cooling fins. The natural heating nature of the Victron heat sink initiates the convection air flow.
Each portable module features its own DC breaker for solar and battery. And the battery connection is achieved via a 300A flexible busbar system (with the same multi level staggered design as the Lynx, with independent fuse for each of the 4x sets of connectors) to achieve a dual 175A Anderson connection to the Victron Lynx 1000A, when the module docks back to the main system. This is a self load balancing and fault tolerance design. Should any issue develop on one connection that raises its internal resistance, the current would be automatically be shunt to the other working conductor. The system is fully capable of running on just one 175A Anderson connection. There is plenty of built-in headroom for extra safety.
Solar panel connection is done via 125A Anderson plugs. As we have encountered unreliable situations where the 50A Anderson has failed due to the insufficient spring pressure on the silver coated connectors, causing heat generation and the housing to fused together. We saw this twice already. So we ditched all 50A Andersons and have no problems with the 125A Andersons. All the solar cables and battery cables are over sized to ensure they run stone cold.
Cerbo GX acts as central control. It is further augmented with Node Red, providing 24x7 monitoring all SmartSolar to detect and remedy sleepy controllers, whereby in the morning the PV voltage exceeds a certain threshold and the controller is enabled but it has not started changing. So far we only see this issue with the 100/50 randomly. Likely a firmware issue. When Node Red detects this scenario it will issue a controller restart and the issue will go away.
There are also BMV712 on one of the battery subsystem together with Victron smart voltage sensors, in addition to the Lynx Shunt. This provides at least 3 different backup references on power meter as well as temperature and voltage feedback. We achieve high redundancy and uses multiple references to detect any potential issues, should any sensor fail.
We run weekly FLIR thermo imaging to check for any potential hot spots.
Glad to report we managed to achieve a higher than 95% during winter periods in achieving 100% state of charge with battery, even under the worst rainy and cloudy days. On the rare days that the system just falls short of hitting 100%, 99% of the time it hits this goal the subsequent day. Our battery system constantly cycles between 88% to 100% on most days during winter., maintaining a very high average SoC.

This presentation is absolute nonsense. So many basic mistakes I lost count.
Too much monopoly in Australia, especially in the energy industry.
Australia has many players but they all band together and act as cartels
Or just not wired to countries that could use it.
Big mistake with the transmission lines being redundant. They will be more important than ever and more interconnections are needed. Especially long distance ones.
It's true, that a single family home has enough area on the roof to be fully self-sufficient on solar energy. but industrial sites use more power than can be collected from a roof-top solar array, even with the most efficient panels available today. The grid as a whole will remain a necessity for industry and infrastructure for quite some time. According to the IEA, homes are ~37% of total electrical consumption world wide. As more and more people adopt solar, that load will be replaced by more businesses, as economies grow. If anything, that will prolong the market life of the grid, with minimal investment in new infrastructure.
The best solution for back-feed tariffs, is behind the meter batteries. Even without solar, batteries can be used for "arbitrage". That's where the batteries are charged when there's little demand on the grid, and power is cheap, then, used during peak hours, when electricity is more expensive. A charge controller with a threshold cutoff can be used, to do this autonomously. At mid noon, when all the grid-tied solar is at its peak, the voltage rises, and the charger can draw from the grid to supply the home, as well as charge the battery. In the evening, the sun sets, solar power tapers off, and all the air-conditioning systems are running at their maximum, the grid voltage drops. The controller simply quits drawing from the grid, while the home continues to run off its battery. Wide spread use of such systems will stabilize the grid, allowing much more customer demand, without any upgrades to the infrastructure. This exact concept is perfect for public DC fast charging stations, for electric vehicles.
Australia is blessed with a chit load of Sunshine 🌞🌞🌞🌞🌞

Battery storage is steadily going up.
The more electric production the lower the prices of electricity... The higher the economic growth, the richer the people.
Lets be honest, Power companies in Australia thought it would be a great idea to buy power at a stupidly low rate of 6 cents a Kwh and sell it back to us at 40 cents a Kwh, however now they are getting too much power they want to charge us for giving them discount power... lol and we as a citizens buy into that and don't say a thing, the world would be so much better if we the people woke up stopped these companies from doing these types things
ERROR at 7:14 *_"... to provide 150 megawatts or 195 megawatts per hour ..."_* First of all, you need to understand that Watts are a measure of power, while Watt-Hours are a measure of energy. What's the distinction? Power is the amount of energy delivered *per unit of time.* Conversely, energy is the total amount of energy delivered, which is equivalent to *multiplying* power (Watts) by the time. In other words, power is the rate at which energy is delivered, while energy is the accumulation of power delivery over time. My guess about the numbers you read is that perhaps this storage installation can deliver a maximum of 150 megawatts (peak, instantaneous power), and has a capacity of 195 megawatt-hours (NOT megawatts *_per_* hour; rather megawatts *_times_* hours). Megawatt-hours is a unit of energy, expressed as a *multiplication* of watts and hours; this is example, 195 megawatt-hours could mean a 1 megawatt of continuous power delivery for 195 hours, or 10 megawatts for 19.5 hours, or 100 megawatts of power delivery for slightly less than two hours. The megawatts and the hours, in each case, multiply to 195.
"Megawatts *_per_* hour," or any expression of power *_per_* unit of time, is a nonsensical, made-up unit, unless ... Well, it could only make sense in the context of expressing a speed of reaction by a power generator, namely how many milliseconds it takes to go from zero output (quiescent) to outputting, say, 100 Megawatts. If it took about 31 minutes to do so, that would work out to 195 megawatts *_per_* hour, but it would be terribly slow. Tesla's mega-packs take milliseconds (I even heard MICRO-seconds, but have a hard time believing it). At 100 milliseconds for 0 to 100 megawatts, you'd be talking about a power reaction time of a gigawatt per second, and that would be slow; so my guess about Tesla's mega-pack in Australia is that it would feature anywhere from 10 to 100 gigawatts-per-second velocity of power output adjustment; not megawats-per-hour.
A channel with the word "Engineering" in its name should not make such atrocious errors in its reporting. If you guys are NOT engineers, yourselves, that is okay, but then you MUST obtain the help of an engineer or two, to proofread your scripts. Just my 2 cents.
Yet a correspondent above, @TimLeech1337 who claims to be an Electrical Engineer says that the problem with battery inertia devices is that they are limited to 1.2 times their rated load before they shut down, whereas spinning turbines can be over stressed 20 times for a short time to provide real support for fault current loads that supports system stability. Maybe physics calculations are not sufficient to run the grid, we need practical qualified engineers?
I am an interested engineer too, but I am not a grid operator.
The unit is watthour, no hyphen needed. Megawatts-per-hour is not a thing, it is just megawatthour.
It would be better to use the unit "joule" which is the proper unit of energy, as 1 watt is 1 joule per second, and clearly shows that a watt is a rate of flow of energy.
Therefore 1 watthour = 3600 joules. 1kWh = 3.6MJ. These are quantities that can be visualized like marbles or water in a bucket, which is what a battery is for electron potential.
These things aren't difficult to grasp, they are just not taught properly, and not used properly, so continue to perpetuate.

Pylontech is the battery system I have fitted in the uk.
It's nowhere near this price. Installed over 20kW/h. That was enough!
I have rooftop solar and batteries but still connected to the grid for those really overcast days. I'm around 90-95% self sufficient year round thanks to our location in the tropics. It works great and if you live in a reasonably sunny part of the world, solar with lithium battery storage is the way to go.
I am the same, but due to the stupid costs in NSW for electricity and supply, I am about to disconnect from the Grid. We have had the grid physically switched off for the last couple of months already. At zero electricity used from the Grid, it costs me just under $170, - a quarter for....nothing.
We have something similar in UK but def need the link with grid as there’s no way we can get enough solar all year round we’d need to massively over egg the solar system to be able to get enough over winter! But we get a good ‘chunk’ over summer we also get most of our hot water from early to mid spring to mid end autumn from solar thermal (def a better version of solar for uk than the solar pv, we only have the pv due to overly good subsidy)
Batteries are TOO DUCKING expensive in Australia. Why on earth would anyone pay the electric company to send their own home solar electricity into the GRID? It makes absolutely no DUCKING sense.
too many people have bought panels only to discover that they turn off during a blackout, having been misled into believing they'd still have power, and finding out the hard way that "oh, haha, no, you needed to buy the much more expensive system if you wanted that", too many people have been scammed by door-to-door solar panel salespeople selling crap panels at a huge markup.
too many people have bought EVs and found that using a charging station at 60c per kwh costs the same per km as petrol, and if they want to charge at home they've gotta buy a special charger and pay an electrician to connect it, which means it takes YEARS for the savings to make the initial costs worth it, and the electricity to charge the car comes from coal anyway because they're charging at night.
government policies regarding feed-in-tarrifs have destroyed all investment prospects, why buy panels that produce energy at home when you're at work and can't use the energy at home, and won't even get any money for the power you can't use? if you're gonna get a solar + battery setup why bother staying connected to the grid if the power you're selling won't even cover the service fee?
the green revolution is dead, killed by government incompetence and dodgy companies ripping off customers. instead of panels on workplaces and carparks (where power actually gets used during the day) we've got panels on farmland and on homes that are empty during the day, not because there is anything wrong with the technology, the technology is great, but the people selling it are con-artists with no "higher goal" than lining their own pockets.
These are the issues I face in New South Wales with solar power into the grid, (1) a corrupt political party sold off the network, all power generation & distribution went from government owned & operated to private or foreign asian governments control, (2) with solar generated into the grid I receive 7 cents per kWh, but when I buy power from the grid it cost me 46 cents per kWh, (3) I will be fined 1.2 cents per kWh for over supply into the grid between 10am to 3pm, What a joke, (4) I will now have to consume all the power my solar panels generate during this time or turn them off, or buy a $10,000 battery plus installation, (thats money I don't have) to soak up my over supply.
Now here what would have happened if the power network was still owned by government, we would have been paid x cents per kWh from my solar panels, the government would have installed batteries at locations around the state, as they phased out the coal fired power stations, in turn at night I would have purchased the power from this battery supply at the same rate OR 2 cents more to pay for the battery installation.
As the power grid on the east coast of Australia is now owned by money demanding foreign owned companies who are in most cases owned by asian governments, we are being treated as mugs, conned into spending thousands of dollars to fit solar panels, & now being fined for the right to generate power, while oversea's countries make money (profits) at our expense, in fact most of the solar panels installed are made in these asian countries as well, ITS TIME TO NATIONALISE THE POWER GRID under Federal Government control & export these foreign government companies out of the country.

I think the best plan with solar is installing the panels and batteries in households. Most households have enough space for batteries to make them self-sufficient, and using rooftop space would be better thna clearing hectares of land
Can i have the contract to clear the desert ? WOW ,,, I will be BILLIONAIRE
Battery costs are high. I have solar panels which costs $3500 to install. However battery would more than double the total cost.
@@MightyCats2011 Batteries costs are not high ,, installation costs are a bit big. $7,000 subsidy for batteries also soon to be approved.
@@tilapiadave3234 I love those subsidies. It frees up money for that jacuzzi I've been thinking about.
Build more energy storage.
Home owners can make long investment decisions into solar power to reduce costs but the grid operators can change the rules at the "drop of a hat “whenever they want to ensure they don’t have to spend make investments or reduce profits .
All the while ably assisted by the compliant government and regulators.
Capitalism with state support whenever profits or dividends are threatened - it’s a mad, mad world.
Here in Queensland Australia the lower socioeconomic suburbs were the biggest adopters of solar, it wasn't until the demand of new homes having to have solar from construction that we saw better off areas fill their roof space with panels, people with money don't care about cost of power as they aren't financially susceptible to price fluctuations.
Steven Greer has spoken about many times the problems with solar.
On his farm in Virginia, he installed the largest legally allowed in the state solar farm. Any bigger, they would need to be a commercial operator. So his solar farm is big. It cost over 80 thousand dollars when they installed it.
Over the winter, they have heavy wet snow fall. One particularly year, the snow took down millions of trees, and left many without power for a week.
That huge system on Greer's farm would not even heat his house for an hour. They had hot water, lights & the fridge running from it all but that was it.
The energy density is simply not there meaning energy density the amount of power for that size and expense isn't going to run planet earth with 8 billion people. Solar technology is too little too late.
Considering we have zero point energy technology & have had since the 50's but they suppress it all, puts things into perspective that with this solar product, they are trying to sell you alternative crap that simply doesn't work.
There are other very practical ways to use the excess. Place atmospheric water generators on city center roofs and running them on some of the excess will produce water for drinking, etc. and also will reduce relative humidity which will make summer (when there is excess solar) heat more bearable to people and animals.
Through evaporation forests and other ways, the sequestered water can be used to cool hot zones through evaporative cooling (when humidity is low enough. Cycle is infinite.
Wrong. You cannot go off grid unless you oversize your solar array to compensate for the fact that you produce half the energy, on your shortest day, of the energy you produce on your longest day. That means doubling or tripping your solar and or your battery to keep the lights on while off grid.
The solution to too much solar isn't just batteries. It's diversity including wind and geothermal.
Pumped hydro storage is more sustainable than lithium battery arrarys, and Australia could and should utilize sea water so that it is reliably sourced.. Elon Musk implanted the wrong tech, because when you're a hammer, every problem is a nail.
Australia is the global leader in percentage of population who has solar. The problem is we have too much solar in relation to not enough storage. Vivid sugar is even in out of the amount of. the amount of electricity because the most electricity will be in the middle of the day when everyone's working and not home So you need to store that somehow. this way this little the world's largest battery pack. was such a success. Almost immediately after being stored. there was an outage somewhere in the system in Victoria and the battery kicked in in under a second to stop any rolling blackouts and supply energy to the sector that didn't have it. We need to start using up a forms of storing energy, like pumped hydro.
One idea for those that are off-grid. If you are a bit short on stored watts, just take your EV to the nearest charging station and bring those watts home.
Do you think that would work sufficiency?
@@JUDITHBEARD-v3f
Depends upon the capacity of your off grid energy system and your driving habits. The most likely case is an unusual period of low system input. If your normal daily driving habits only use part of your EV's charge, then it should not be problem. It would be an interesting strategy to downsize the home energy system and depend more on the EV battery.
Battery. If battery full, desalination. No need for water, Hydrogen. If Hydrogen price drops, bitcoin.
My house is 100% solar but have to get a battery now the government wants to charge us for feeding into the grid as it apparently can’t handle it from everyone’s solar
Why that Dutton is still making his 7 Nuclear Power Plants proposal , which will take 10-15 years
to build ???
Because the fossil fuel industry wants to delay the inevitable as long as possible. Nuclear is a divide and obfuscate issue. If they can delay the switch by years before admitting nuclear doesn't make sense, they have kept us buying their products.
Delaying the phase out of fossil carbon, by fear, uncertainty and doubt (FUD). That's how you kill investment in energy, locking in the status quo for as long as possible.
@@noelkelly4354100% agree and Dutton is at risk of making this too obvious.
6 years
@@tilapiadave3234 perhaps in a country with a mature nuclear industry. Not in a country without one that has to have significant legislative change to even begin.
Energy is wealth in our society. Our rise as an industrial society and our massive population growth are directly tied to our exploitation of energy from waterwheels and windmills and then whale oil and coal, and then hydroelectricity, petroleum and nuclear, and now modern wind, solar, and batteries. Because energy is wealth, Australians will find a way to profitably store or use the surplus, refining minerals, whatever.
So people having freedom and less taxes is bad for the government, got it 👌
It's not off grid the power companies want. They want people to have batteries to store power for usage in times of power outages or black outs. If people go for off grid power usage then that cuts the power supply companies out of the equation which the companies naturally don't want to happen.
The larger solar panels are much more affordable in context as shingles creating a 30 year roof, or sundeck above roof, I am hoping to use such a system using a welded and epoxy coated U channel or H channel to support and act as rain gutters and walking channels . Here in Mexico with 100" rain a year and enough sun for a 4 year payback .
The problem is the NSW state government sold off the “poles and wires” to a Chinese company, yet to take in the solar infeed requires a huge investment in this now private network. So who will pay?
The consumer!
@11min, more solar power means more pylons, not less
Pylons all the way from the roof to the home battery to the house.
I'm sure many industries would like cheap power. Why doesn't Australia use it's interior energy potential to lure companies to Australia.
Exactly
Transmission, storage, reliability. Cost, cost, cost. Why doesn’t England export freshwater? Rain is free. Water isn’t.
Because of vested coal mining interests and politics. And the interior of Australia is nothing like the interior of America or Europe. Tough old country with extremely low population density and infrastructure.

Powers that be, bureaucrats and big business not want to lose there outrageous profitable revenues.
Everything in the house is electric except cooktop and water heater. Wouldn’t want it any other way.
Yet electricity gets more and more eXpensive... 😥
Off grid sounds like best option. 👍
Edit : Australian Government needs to BUY BACK the grid infastructure, that it sold off in the first place......
Well get a battery for your home then and heat your hot water and pool with the rest...
it´s not too much solar, it´s too lazy government who don´t upgrade grid. same problem in estonia. now they ask 1,6 mil eur from new connections
Off grid is not so easy in the northern hemisphere. My solar output in the winter is about 1/10 of that in the summer while I mostly need that power in the winter. With a battery I could use cheap night power to charge the battery and use that on cloudy days but the price has to come down by about half for it to make sense for me. Sounds like in Australia it is easier to go off grid. Maybe I will move there ;-)
the sun is also finite not renewable. the rear earth in the panels that wont be recycled, are also finite.
Oh shit. When is the sun switching off?
Poor people don't have expensive houses. Solar panels can be afforded by poor people now and batteries will follow.
If you have the time. To do it yourself it is 100% possible for the poor as I am. I have 3200 watts in panels, 3000 watt all in one invertor, and 24kwh. Total cost is 7 grand. When we expand to take on 90% of the house it will be even cheaper.
Solar panels are so cheap now there is no barrier. There are large panels going for $25-$30 EASY. They are almost giving tons of them away. Inverters are inexpensive for the most part. Even the price of battery storage has plummeted. The top name brand batteries are still expensive but the DIY and lesser known brand batteries are super cheap compared to just a few years ago.
where do renters fit, in this narrative?
@@pdipatria In Germany we have "balcony solar panels" + Batteries. Just buy a set, attach them to you balcony or anywhere else there is space or talk to te landlord etc. This already makes a great difference
You are not poor. If you were you would see just how stupid that statement is.
Home and small business-scale batteries need to drop dramatically in price. Home-scale battery storage currently has an installed price of over $10,000 per kilowatt hour. Electricity is typically generated and transmitted by greedy, price gouging and corrupt monopolies and cartels. That price needs to drop by 80% or more to really disrupt the cartels.
Those are premium battery storage companies. I just built a 14.1 kwh battery for under 2 grand. At that rate I could build 6-8 14.1kwh batteries for the price of 10 grand.
The weak link in domestic solar is the storage. Batteries go belly up all to soon and replacement is expensive,robbing the system of a lot of efficiency. So a storage device/system that is entirely mechanical. Envision if you will a seriously heavy pod (broken glass, lead,maybe even steel being winched up all day long and ready to release its stored kinetic energy in an instant. Only maintenance would be a cable replacement once in a blue moon. When I have the dollars I will be building
mine.
Obviously it isn't hat Australia has too much solar power, rather bad grid design.
You make a big deal out of a miniscule battery ,,, 100 MW ,,, how long would that continue supply if the grid went down ? 5 minutes?
So how to we explain increased energy prices in South Australia!
Charging for exporting power during middle of day is quite the stab in the back. The temporary solution for home owners is to get a battery for home. The permanent solution is to get a BIGGER battery and say goodbye to the grid connection. Justice finally after years of us all being slaves to energy companies. 20KwH battery installed for $13K total.
If all of the energy produced by renewables was dedicated to producing even more renewables, then renewables would become exponentially self-reproducing to a maximum limit, at which point almost all of the energy they produce would become free energy.
Misleading heading as it was just a plug for the solar industry that highlighted the good aspects but totally ignored the pitfalls and true costs. It especially mislead regarding batteries and glossed over the economics of running such a system. This is a particular issue for the growing higher density housing in cities and the need to have a grid and 24 hour power source for those cities.
Like so much of this propaganda, it fits well for affluent people with larger single dwellings that can carry sufficient panels to generate meaningfull amounts of electricity to tide over nights and poor weather days as well as the wealth to afford the cost of storage. These costs are still well above the break even point over the life of the product.
Add to that, the rest of the population that doesn't fit that demographic and the propsal fall flat as you still need to generate stable power for them, for industry and the like. Solar is a nice addition for some but not a solution for all.
Farcical short term planning, nothing lasting more than a few decades, while base resources are finite. Plus a massive toxic recycling problem. All after the IPCC stated with absolute clarity in AR6 that there is no climate crisis. Industry loss due to poor quality 3 phase. These people couldn't plan a beer in a brewery.
This can transform Africa overnight who has very little power grid in place.
We buy at 46 cents kWh because we do not have a battery.
Plus, there is a $1 daily connection fee. So 50cents kWh.
With V2G and 2nd hand BV then all electric offgrid will screw grid cashflow.
The grid is a $TRILLIONS infrastructure investment that needs cashflow, $100sBILLIONS cashflow every year.
BVs will allow more offgrid time for grid customers.
No grid cashflow when the sunshines.
No grid cashflow when the battery oversized battery supplies after sun down.

Happy days.
Lol! Tesla 15kwh powerwall for over 10'000 dollars? I just installed a 35kwh powerwall using 2 batteries with JKBMS for 120'000 THB (around 3'000 dollars).
Interesting facts! Thanks for sharing.
Remember folks, fossil fuel is both energy dense (so compact), and its a built in battery as its stable until used. You would think a great solution would be to make synthetic hydrocarbons from solar power and then burn them when needed. Yah, not a new idea. But endless free power from solar must be matched with really good battery storage to just end oil.
That’s literally the plan of terraform industries
Put panels on open city spaces not green fields
You now have to pay energy companies for your excess solar power you store 😊
Great content and editing, thank you. 🚀
With a population of only around 26 million, Australia is a relatively small market for major exporter countries like China.
And with huge natural resources, it should not be that difficult for their government to take good care of their small population.
So many things wrong in this video. For a start, the WA grid is NOT connected to the eastern seaboard. And Megawatts per hour is NOT the same as megawatt hours!!! Really, if people like this want to be seen as providing factual information, they really should attempt to get their basic facts right!!!
kWh is "kilo-watt hours" not "kilo-watts per hour". 1kWh means 1kW for 1 hour, or 10kW for 0.1 hours or any other similar combination.
A better grid can reduce the amount of storage needed, so probably the demand for substations and lines will rise.
Grids are super expensive and unreliable.
Best solution is for everyone to have their own batteries and download power when convenient or better get their power from the sub
@@allangraham970 it is not economical only use batteries as storage. My house (middle of Europe) hold uses 3 times of energy in winter that the PV system produces. In summer it is the opposite.
With wind energy can help and that needs a powerful grid
Cost of batteries is still way too high to make it attractive. Return on investment is at least 7 years, by then its efficiency has dropped
Actually the lithium phosphate batteries are going past 10 years without losing hardly any efficiency. Most of them are lasting 15 years before they need to be replaced. When they fail though, they just die instantly and don’t work anymore. You’re right about the expense though, a whole home battery bank will double the cost of your solar install.
Are Community Solar arrays with battery storage in use in Australia?
It's about the power companies ability to manipulate the prices per kwh.
And keep it within a price range they can profit from..
Prices should fall but they won't .
Quick. We must build the Australian solar death ray!
Battery draw power from the panels not panels push power. BMS can control its input.
off the grid is not possible, government is not ready to let population free. Plus the infrastructures CAPEX need to be from the governments so that they can get cheaper money loans. Otherwise the cost of energy will skyrocket
(1:15) "And the pioneering Tesla 100-Watt Lithium Ion Battery was installed . . . "
How . . . ?
is this even a problem? simply go offgrid or put a ct limiter 🙄
That would be easy - if people could afford battery back-up.
Solar is awesome. I do various experiments with solar panels living off-grid in the Mojave Desert. My newest endeavor is storing heat in sand. Directly wired to the solar panels. Using a step down or step up DC to DC power converter you can run all sorts of electronic products like radios televisions on and on. It's a lot of fun experimenting with solar.
There is no such thing as "too much power" it is always too high pricing. There is always a market clearing price. There will always be more customers, such as AI and digital currency customers. Is it possible that the utilities are too stodgy to lower prices and find new customers at the lower price?
Er it was more like 100 MW, 120 MWh, (not 100 w) Enormous difference!
Does this bloke know what he is talking about?? At the 7'18" mark "to provide 150 megawatts or 195 megawatts per hour (sic)". I do wish these people who purport to know a bit about their subject matter, could actually demonstrate same!
10:30 What? Lower demand for oil will somehow make the price go up? Ever hear about supply vs demand in economy 101?
Thank you.
Pulse we must look at the total problem.
Millions and millions of customers and millions of miles of national grid.
And generators.
The key is the grid being a $TRILLIONS infrastructure investment and ROI,return on investment, to the grid owners.
$100sBILLIONS in cashflow.
It turns out that the customers cashflow is critical to the grid.
With millions of V2G BVs oversized battery parked 23hrs every day and all night long and rooftop PV then customers cashflow could stop the grids cashflow when the sunshines.
This is utter death to the national electrical grid, the $TRILLIONS and $TRILLIONS infrastructure investment with superannuation funds and government and othe investors suffering.
Too many talk about the central generator and ignore the millions and millions of customers who must stay on the grid and with their BV's and rooftop PV, if ignored can go OFFGRID.
OFFGRID can destroy the national electrical grid infrastructure.
This would be an utter waste of the national grid.
The grid was built over 100years, 10 decades, with billions of tonnes of resources and massive financing.
Too millions and millions of customers homes and buildings and industries.
No CO2 emissions and clean electricity and new economies in a warming world it is this big picture and direction that is important
8:35 you mean CO² emissions not C² 😂
A charge tax for doing what is good for the environment? Sheeeeeet. I would invest in more batteries for my properties so that I can disconnect from the grid and all that bs.
Too much solar power for whom?
Most vehicles drive building to building.
Most vehicles are parked 23hrs every day.
Most BVs oversized battery can be topped up daily on trickle currents.
V2G selfparking selfplug-in BVs will be able to bumper plug-in to a $60 wall outlet at every buildings carpark space, ezi pezi.
Trickle currents all day long and all night long ezi pezi.
Rooftop PV panels shade hot rooftops all day long in warming latitudes. What could be better ??
Well done NSW!!! 💪

This is not engineering its nonsense. Solar voltaic electricity generation if not being used to charge storage is nearly worthless. One large cloud passing over a solar farm causes its output to drastically falloff requiring instant makeup typically supplied by natural gas turbines running at at high availability service idle. Running at service idle uses about 70% of the fuel as full throttle, but produces little useable power. This is the cost of high availability. Old coal fired power plants were not made to supply instant makeup nor were old nuclear plants. Hydro power does this well.
The public power grid makes it own electric power much cheaper than the forced buy of solar voltaic power that is erratic and has to be conditioned. The public power grid can't refuse to buy the peaks of solar voltaic generated electric power. In the case of over supply of solar voltaic electricity the public power grid has to spend money to start and run natural gas turbines at high availability to offset any dips in output just to sell power at low cost to other power grids to get rid of it.
These forced buys of erratic power to the public power grid costs the average rate payer a lot of money. Instead of passing all these costs on to the rate payer most of the public power grids forced to take on these at high costs forced erratic power purchases forgo improvements and maintenance to the power grid making it more prone to black outs.
Tesla doesn't want to sell its solar roofs without it being a part of their power wall battery storage. That isn't just to sell more product, its because Tesla thinks big and doesn't want 10,000 of their solar roofs to be an icon of distribution to the public power gird. The battery electric power storage allows Tesla to network the power walls together to sell contractable peak power or emergency power to the public power grid. This is contractable power for a set fee for a set time at grid quality.
In the video using Australian dollars that are about 2/3 the worth of the USD and the Euro making relative amounts 50% higher the cost per kW/h of home battery storage was at nearly $10,000 Australian. That's extremely high when car batteries in 2023 world wide were averaging at $139 (USD) per kWh.
It's stressful and less efficient to discharge batteries quickly even with chemistries designed to be good at it. It is not really discussed what is a reasonable discharge rate, but 4 hours from 90% to 20% SOC for lithium ion daily use is likely reasonable for power grid use. The batteries will probably last less than ten years. When looking at a power grid battery supply it can likely provide 1/4 of its rated capacity per hour with the ability to provide high peaks. So 100 MWh battery could provide 400 MW for five minutes or even a GW for a minute, but for daily service likely should not be pushed past supplying an average of 25 MW/h. 100 MWh battery would be the same battery capacity of 123 Tesla Model Y with 81 kWh battery pack.
One natural gas fired GE 7EA turbine can make 90 MW in simple non steam cycle www.gevernova.com/gas-power/products/gas-turbines/7e. Its very compact fitting into the space of a city bus and they typically last 100,000 - 150,000 hours with their being 8760 hours in a regular year that is over ten years of nearly continues service with some shutdowns for inspections before the rotor it considered at the end of its service life. It can run largely unattended. It is the low capital cost, high ease of situating, naturally very low emissions, low maintenance, low staffing cost, fast start up and their ability to follow large changes in power requirements quickly that makes gas turbine generators very attractive for generating peaking loads. Their fueling costs are high.
A modern ultra supercritical coal plant should have fueling costs at 1/3 to 1/4 the cost of natural gas turbine combined cycle generator. Much of the time the steam cycle in a NG combined cycle plant that adds a big jump in efficiency comes in too late to be highly useful.
It scientifically impossible, that is with all the science we have today without new science, for greenhouse gas behavior to cause global warming. All the greenhouse radiant energy from the earth is completely absorbed in earth's greenhouse effect within 20 meters of the radiating surface by greenhouse gases which would be the same if the strong greenhouse water vapor were the only greenhouse gas in the atmosphere. Water vapor varies hugely across the earth's surface. Most of the time except in the driest deserts all the greenhouse radiant energy is completely absorbed in much less distance than 20 meters from the radiating surface.
Did you base your finding in North America, because most of the sola farms in Australia are in the sunnier parts of Australia which has few cloudy days and before sola farms came along, small communities were using diesel generation. People who live in remote locations like sola generation because they do not have to breathe in diesel fumes.
People who have sola on their roof in larger communities are encouraged to use the power they generate themselves, by using it to heat water, cool or heat their homes, store the power and so on.
Casey handmer's solar pridcuing hydrocarbons seems awesome.
If solar panels work of heat and light could you not build a box or unit and light a fire inside?or use a electric heater on a circuit or a low watt high light Florence bulb..
Just how OLD are the datasets used in this video? 😮 2020 😅
With your massive dependence on China on both the demand and supply side you won't have a problem because China will "take care" of it for you. I saw your solar panel import numbers, for instance, and it is truly shocking. Also your exports, which are largely minerals, are so heavily skewed towards China. And now if you don't have good relations with your #1 trading partner, what can possibly go wrong??

If the author thinks the average Australian can afford $10k for a battery that will only last a few years, he's nuts.
they aren't lead-acid batterys now, there are already batteries that will last for 20+ years in cars, and stationary batteries will last even longer. But don't spend your money if you like paying increasing power bills.
