I live in Northern Ontario Canada and I have been off grid with solar on the north shore of Lake Superior since 2004, charging two EV's since 2014 and now I power my entire business and machine shop off grid with solar.
I have saved a fortune in money I would have spent to rent my energy, generating your own energy is the best investment you can make.
Good to hear, especially that far North with far higher upfront solar costs back then.
Should be relatively easy for me here in N. Commifornia lowlands, today.
More power to you 😁
@@Mrbfgray With todays technology its a breeze. I am building my off grid non propane camping trailer right now, it will provide extra battery power for my Rivian to increase its range while towing the trailer which is charged with solar.
What do you do in winter when there could be days without sun. Also you have to clean out the snow covering the panels
lol Such ignorance and foolish nonsense.
I have a high pressure air system to clean my panels, cloudy days reduce panel output and that was calculated and built into the system, I have plenty of battery storage.
Ask me how what I did with the over $250,000 I would have paid to pay if I had been on grid and paying for energy.
If batteries come down in price like solar then every farm in Australia will be off grid. Regional towns I would imagine too would be independent. Local solar, wind, hydro, batteries and diesel back up generation would be perfect. Diesel generation is expensive but very cheap to lay idle which would be most of the time. Such a huge reduction in the thousands of miles of high voltage transmission lines and the poles and wires and the maintenance required to service remote communities would surely allow for cheaper grid prices for city customers.
I live in the south east of England and have a 4.7kw solar panel system, I also have batteries. I should also say that the house position is excellent for catching the sun. So far this year I have had 34 days when my roof has produced less than 5kWs in total for the day. There is no way that I could live a self sufficient life without the grid. I am very fortunate that I can charge the batteries over night at a very cheap rate in the winter months.
@googlelansdown What batteries and how much cost ?
This February was probably the worst of the century in term of sun exposure.
I live in France with a 4.5kW system and the entire February I produced only 127kWh. This is less than my weekly consumption.
If you live in an area where heating or AC is mandatory for more than a 1 week straight per year, going off-grid is basically not option. You would need hundreds of kWh of storage, or at least 2 EVs in your garage dedicated to V2H.
@@itsyo42Do you have a battery for storage and how does it cost ?
...when extremely cloudy you still get around continuous 400 W. I doubt that people with appropriate batteries have a gap that they have to fill with external energy.
@@itsyo42I only use 150 kWh...per quarter. Apart from an electric car I don't know why other people are wasting so much energy.
In California here in the US the greedy electric utility companies like PG&E are ripping off homeowners by lowering the amount of money the homeowners can get by selling their excess electricity to the electric utility. This is hurting rooftop solar in the US.
Florida also... we have a net metering law, however solar companies have instituted a minimum monthly charge regardless of how much you generate. Its clearly against the state law but has het gone unchallenged. Its going to lead to many homeowners going off-grid as soon as battery prices allow it.
South Africa also.
I wonder if u guys (or us here in Aus) could approach your neighbours and sell it to them. Would that be legal or could you get away with it?
Yeah we have the minimum monthly in CA to. PGE offers and electric car rate but that transmission charges and other stuff on top of it so the EV rate comes out the same as if you didn't have it. .35 cents per kw which is the same charge as Suprechargers right now at least during off peak.
Yep in Australia too, they keep lowering how much they pay.
I've had my full house solar system with house batteries for about 2 years and my Tesla for 1 year. Not enough production capacity to go off grid but we are super happy with the results and huge savings. Added to that the local grid energy company provides a 2nd electric meter fir the express purpose of charging an EV with off peak rates. Nice. Duet cheap too. Hence my house and transportation costs are crazy low. Thailand gets lots of "sun days" and the decision to add solar a good one. My mathematical payback is about 5.5 years. 👍
I'd love to see this report! 50% already are independent? I call BS.
In America you can google the EIA.gov. They have a report of all the energy consumed & where it’s been sourced. It’s up to 40% clean over here now ending in 2023
Exactly, not a word about the need to store loads of energy if you want to be off grid so yes, BS indeed.
@@tellyboy17 I don't know about the report, but battery back up is a good way to store energy.
@@MyUniversalUniversity But it's not a ticket to completely off grid except maybe you live in a region with great all year round solar irradiation, substantial excess capacity in your solar array and a really big battery pack. Lots of ifs that add up to high energy cost.
IKR? And then he says it will take until 2050 to get to 75%.
Hey bud great content! Just finished our 20kw whole house off grid setup in sunny Queensland. 6 months in, and the savings are huge! NO bill and we run the AC or heating when we want not when we can afford to. So much better and 100% in control. 😎
Thank You for recognizing many people do *NOT* live in homes.
More people live in apartments and Row houses . Especially people who live in large cities.
Compared to people who live in houses with garages.
Thankyou. The value of my house(s) just went up again.
Not necessarily a big problem. You need to start a local cooperative. All buildings have rooves and a VPP style community or local battery can be managed by such a cooperative. Anyone who rents pays individually for retail electricity, so lobby for the ability to licence the coo-OP as a retailer (actually 'gentailer') and encourage all included residents to purchase their power from the co-OP!
Great news! Hopeful news.
Yes Sam absolutely correct. But faster than you think, because it will become self propagating. The more people go off grid, the more energy companies will have to charge to cover production and maintenance costs. So more will be forced off grid and so on. Big energy companies either electricity or hydrocarbon, are slowly loosing their controlling grip on society and its not before time. Love your work mate, hoping for some better luck for you and your family. Cheers.
I was thinking that, to maintain the grid, it's quite expensive, if more go gridless, there are fewer consumers for them whiles at the same time, they still have to cover a wide network, so the cost to maintain will still be high but the money coming in from consumers could drop a lot, which they could very well pass those cost onto the existing consumers, which will push more of them to go gridless.
To really go gridless, solar alone isn't enough unless you massively oversize it to cover the winter months, but ideally, what's really needed is much cheaper and bigger energy storage that can cover days or even weeks, but even better is if we can have solar and wind at a local level as they would complement each other and would reduce how much energy storage that's needed because a more consistent flow of energy will be generated throughout the year.
Unfortunately, wind at small scale don't seem to perform that well in urban areas, if that can change with a lot of experiments that are going on with vertical wind turbines, a mix of solar and wind would allow most of us to go gridless and you wouldn't need much energy storage to do it.
went off grid a couple years ago,..i dont miss power bills.
@user-uk8tl3xy9eNope! Do use Fire on cold winter nights. Mostly a Low Energy user(Frugal but Very Comfortable) Have up to week...of Sol Storage Autonomy🌅All the Best to Your Independence 🗽
Sensible to be "off grid"or part of a community "mini grid" as Grid operators are making billions from shifting electrons around rather that getting local grids balanced with storage rather than travel hundreds of miles!!
I retired from a power company. My former employer is moving towards solar. Investing money in technology to predict demand with where the sun is shining and moving power where it is needed. They have several solar farms and more are in the works. I live in Florida and most of the state land is not on the grid. I can see people moving deeper into the woods if they can get their energy independently. To get away from government control over our lives.
You’re gosh darn right! My bill for my small studio in NYC is $132 this month, I called ConEd and they said only $44 was energy the rest was delivery a .. only 1/3 was energy! Everything else was bogus charges
Building and maintaining the power grid actually does cost real money.
@@alanjm1234 WHAT! Not "bogus charges",?
Those wires don't grow up there by themselves?
I pay 8.1 cents per kw/hr for my electricity. Bur surprisingly, it costs money to bring it from the windfarms to my house. Another 6.7 cents. Includes taxes, which as you may have heard, are necessary to keep a civilization running. Nothing bogus. Grow up.
Energy retailers need to evolve in two ways:
1) into energy transactors to accomodate home electricity generation
2) into location agnostic providers for domestic & mobile electricity consumption. Kind of how the telecoms market had to accomodate home/mobile broadband.
I spent a year living in a van with 300 watts of solar, 260ah 12v storage and a 3000w inverter
I look at the power in the home now and see it as just wasteful. There is no reason to be grid connected. And when bushfires took out our power supply to the home, I plugged into the van
So now I have to live in a f@$#king van to keep the greenies happy?
There is a realistic solution to billions of people that need shelter!
Thanks for this
@@davelewis9439 no mate, sorry, you are most definitely not invited. Firstly its your issue with comprehension and second your foul mouth
I've lived off grid for the past 15 years. What will drive more people to go off grid will be the rising prices and reduced reliability that changing the grid to renewables will bring.
I'm mostly electric at my home, my tenants apt. has gas , I'm planning on a 10 to 12 kwh solar array in my back yard., with 3 battery reserves for the 3 buildings on my property. My monthly bill now is $600 to $800 , the system I'm designing will cost me 35k approximately. About a 5 year return on investment, not including the small amount being put back into the grid. Also, tax rebates . I'm waiting for perovskite panels to be released for residential application. So im on board with the renewable transition. I will charge my Tesla Y by solar, so that's cool. When it's my turn to get my Cybertruck, I'll be all set. great vlog Sam , ty again for great reporting
Perovskit panel
I’m in Michigan, off the grid for water, sewer, food, and eventually once I get batteries, power. As for transport, 2011 Nissan Leaf.
Hi from the NW UK. You raise an important issue Mister Viking.
We’ve gone fully electric and the day we had the gas supply removed was a good one! Averaged over the whole year, half of our home energy comes from the Solar panels on our roof. In the peak generation of summer, we basically run BOTH our home and car from our Solar. :-)
Wind power for home use appears to be very much in its infancy. This needs serious development yet. The RidgeBlade system looks promising.
Cheers.
@user-uk8tl3xy9egrid electricity
Count me amongst them. Have solar and getting quotes for batteries. Don't know if I'll be totally off grid but our home will interact a lot less with the grid.
What I found interesting after we got our solar panels up and running, was the actual app we got. Suddenly you could really see where you were wasting energy, not only how much you were getting from the panels. Why were we burning 350W through the night? Why am I using so much energy to make 1 cup of tea? Within a week of having the app, our most energy consuming light in our house was the 40W heat-proof oven light. The app alone made a huge difference.
Great reporting. True. I included.
I think the main thing to come out of all this, is the potential decentralization of the power supply chain. Here in NZ if we have a bad storm or an earthquake, large parts of our country can be temporarily out of power. If we can become a more decentralized system, it would mean a major event in one part of the country will not affect other areas so badly. If some of us had v to g with our evs or a home battery storage system with solar panels, others would not need to suffer a blackout in that situation, and the contributors would be paid for their input, hence the need for a grid. It will happen eventually, and both Ausi and NZ are both in the box seat regarding renewables. It is very windy here in NZ, and we do get some sun here in the north, I lived in OZ for many years, and I can tell you there is no lack of sunshine there!
It's is a cute dream but part of the deal with being grid connected is that your power can be shut off when the grid goes down and that is critically important to safety. You, individually, off grid? Yes. A community generating it's own power because some power lines went down, much more complicated issue.
With 30-40kWh energy storage in many places off grid is a good solution .
Depends on climate.
HVAC requirements can be significant, potentially requiring 5-10x more battery storage.
Although, in many areas, air conditioning loads tend to follow sunlight hours, and thermal storage can help reduce night time heating loads.
Best to substantially install excess solar, if room allows, along with a small wind turbine or two to help reduce battery requirements.
And batteries are getting cheaper. LFP (LiFePO4) in now in the $50 USD per 1kWh range, at least for manufacturing. Which puts a 100kWh battery in the $5000 USD price range. That's actually getting quite feasible for house battery power
But how much would a 35kwh battery cost? 70k?
@jeffl4810 50 per kwh for a battery!!!!! Bahahaha. Your dreaming pal.
@robertfonovic3551
Actually, looking it up, the first article in Google says LFP is heading to $36 per kWh by next year...
CATL cells cost $56 per kWh, and that's old data.
LFP is about 30% cheaper than NMC type chemistries, and lasts longer. However, new chemistries such as NMC 532 are breaking the longevity advantage - that chemistry is stated as a 100 year, 4 million mile battery.
Note that Lithium (Lithium Carbonite to be exact) had a massive run-up at the start of the pandemic. It has since settled as more mines and industry re-opened at full capacity, along with new mines operating, and expansion of others.
Note that a BMS and housing/casing also needs to be added, but those are not particularly expensive compared to the cells.
For household use, a themal management system isn't required. Those are needed for EV useage, as they're required to charge in 10-20 mins, pull a mega-watt or two in performance situations (10-20C peak discharge currents). And stay in environments that can go from -40°C to 50°C.
Building usage has temps 20°C +/- 5°C and significantly lower than 1C charge/discharge rates. This is much less demanding on the batteries.
Sounds like Alberta where $20 of actual highly overpriced energy will end up costing you over $100 with add on mandatory fees... Connection fee, carbon fee, administration fee, GST fee, transmission fee... And there's probably more. If you have enough space it's definitely worth it to get a solar/wind/battery set up going here especially if you can get off grid to avoid these BS charges... At this rate we'll have created electricity that's "too cheap to measure" but they'll still find a way to charge you for it, especially if you're grid connected...
Yeah, we’ll, “they” own the grid. This is capitalism and most of us worship it here in the lands of freedom and liberty.
yo NZ, its the same
Yes I am at a turning point here in Australia, I have grid connect and off grid power, the only reason I need the grid is for exporting power with a good feed in of 12 cents, this feed in is being reduced over time and come Aug 2024 when my 12 cents will likely only be 3 to 5 cents offered on the table for exports which wouldn't even cover availability costs to stay with the grid, I will remove myself from the grid, my grid usage is only 90 kwh a year!!, my off grid setup is 8kw of panels with 52kwh of batteries, when my grid connect is shutdown it will give me an extra 15kw of grid connect solar panels for off grid use, along with an upgrade off grid inverter going from 5kw to 11kw now sitting in a box waiting for the moment
Another miracle. Keep them coming!
If "millions" get off of the grid perhaps there will be capacity for charging more cars.
Have a rural property, off-grid[...forested], and it will cost $25-30K to have just electric installed, including clearing and poles. Why would I do that instead of going solar?

Government will end up taxing you for sunlight hours in your area. They will always find a way to raise revenue.
They did that in Spain in 2015.
@@sang3EtaHow much pay because you produce your energy ?
20 years ago, when I was a team leader in a major Council IT team, our systems were already set up to charge residents for potential to catch rain water. Undoubtedly, it was just more profitable to separate water from local government and just form another government body.
@@ronan4681in Uk we pay for rainwater on property
@JoeyBlogs007 You mean the fossil fuel industry will "lobby" the GOP to tax sunlight.... There I fixed it for you
A Tesla solar roof with ample power wall batteries have run a house for 3 - 4 days without sunlight which happened when the California bankrupt power grid turned off high voltage transmission lines to keep them from starting forest fires which had already started causing there to be 3 - 4 days of heavy smoke and little sunlight. It can be done, but is extremely expensive and the person doing this said they needed to get a backup generator for such situations.
by the end of the year my house in WA will be 100% (probably more) self sufficient & I will actually be making money by selling back to the grid.
Self sufficient? Does the sun shine year round day and night where you live?
@@tellyboy17 You ever heard of batteries???
@@davidtuer5825 I know but most solar panel owners seem to think they make a valuable contribution to energy supply without them while they are really just parasites delivering energy when the sun shines and energy is abundant and might even have negative value while taking energy from the grid at night and the wintertime when energy is scarce and expensive. To solve this energy suppliers should never be obligated to pay more for solar than its really worth at the time it is supplied.
Think about the effects of mass adoption of solar, residential battery storage, storage from EVs and the software used to manage all of the various sources to generate income or reduce electricity costs.
All of this technology exists today. We are at the bottom of an energy "S curve" which will very likely make cheap electricity available to millions of consumers in underserviced areas...
Good reporting, as an Australian who is 99% grid and oil indepent, I agree - here in Australia Solar panels have become so cheap thatif you can have them on your house -and don't - then you are losing money....the pay back period is very short....
unfortunately or fortunately, not all countries have australias climate
@@debeerizExcept europe & canada , rest of the world is kind of sunny area
@@tarunsingh7326 I live in Northern Ontario Canada off the gird perfectly well. Stick to reviewing shades of nail polish.
@@debeeriz Climate doesn't mean squat for solar production. Did your mother have any children which not born brain dead?
Given the rates they charge in Australia for electricity, makes perfect sense.
I lease a 5,000W system and it's not enough to completely wipe out my electric bills. I can hardly wait for the panels that deliver twice the power of my current system to see if I can go off-grid.
The only real problem is storage. The amount of resources are a problem. There needs to be a break through/out technology for storage. The second major issue is politics.
I think eventually the grid will be the back-up. In Virginia - a lot of people have solar with battery back-up and a propane tank based generator.
Solar and in house storage will change building designs and siting/orientation. I see a lot of house roof remodels in the future.
Selling this to the average household/person will be easy. We'll still have *_a grid,_* but it will be for _co-operation,_ not _exploitation._
Everybody will get all _gung-ho_ for the financial freedom that living _off-grid_ brings.
It's also a matter of *Individual* and *National Security* since you are no longer being held hostage for your energy by people who really *_don't_* have your interests at heart.
What this survey doesn't measure is the value of freedom from govt. that varies greatly. "We", as individuals, only need to be free to choose where our resources, our wealth, is spent. I would choose a micro-grid, green energy produced locally, to avoid transfer loss, thus more efficient, OR, off-grid, rooftop/battery. But, NEVER the grid, an energy monopoly that is always the most expensive, and ultimately unsustainable. Why? Monopolies create short-sighted greed that grows and grows over time, destroying itself and those who allow it.
This is what I have said many times....govts should make solar installations as cheap and plentiful as possible. This will almost eliminate a lot of the upgrades needed in the power grid. It also distributes power outage risk and makes huge area outages a thing of the past.
Distributed is the way to go.
who owns most power stations and grids, governments, so why would they try and kill their own cash cow
Big surprise. Solar racketeers think government owes them a living.
Leaving the grid might be good, but staying on the grid, selling excess stored energy to the grid during hours of high demand is a paying proposition.
Can't get enough of this channel
Solar, paired with batteries or residential hydrogen, can provide plenty of power. I agree with you, Sam.
Vital info Sam
20 years ago, when I was a team leader in a major Council IT team, our systems were already set up to charge residents for potential to catch rain water. Undoubtedly, it was just more profitable to separate water from local government and just form another government body.
They tried to charge me for catching rain water and my lawyer destroyed them in court and then they had to pay my lawyers fees as well.
They are lucky they lost because the alternative would have been lights out for them and their families.
Now that I am using my EV’s V2L to feed into my solar system, I have given my electric meter back and gone completely off-grid - videos on my channel.
While I’d love to see this happen, my skepticism lies not with panel tech & cost but with the installation labor costs required to make it happen. Those costs will only continue to rise no matter how cheap solar panels get.
Good news! 🎉😊
Off grid may be an option for those in warm climate countries without a large home heating requirements. For others in more variable climates it isn't unless building a new, expensive, but highly thermal efficient home.
If power grids buy back surplus, MANY will stay connected. Wholesale rates is NOT too much to ask.
It's easy....give us access to Chinese LFP prices and I'll be off grid by the end of the month
@user-uk8tl3xy9e compared to Europe I see differences in kWh of over 50% (less). Even EUA prices are way better
In the Pacific NW we can harvest the equivalent of about 3.5KWh per KW of solar panels each sunny day. However, in winter I have seen days of as little as 2% of this, and a week or more averaging 12% per day. To truly go off-grid. we would probably need around 80kWh of batteries and 36KW of solar to be able to get through winter. Going off-grid needs a backup generator when all else fails, but may be possible without this in sunnier southern states in winter, but would still be costly. Most houses do not have roofs with a large enough area and would need to mount panels on the ground. Smaller lots, shading and HOA regulations would prevent many from using ground mounts.
Or you need a V2H vehicle and charge it at public chargers in the winter
Or you could upgrade to a better system but that would not serve your idiotic narrative.
@@gerryburde5663 It's an idea, although the nearest charger to us is 20 miles away...
@@user-wt5bf4rw7e Why idiotic? We only have 12KW of solar - upgrading beyond 36KW would be very expensive and would mostly be wasted in the 7 months around summer.
I hope one day soon, I’ll be able to leave the grid, and the greed of PG&E behind.
Another way to view an EV is it being a large battery storage system on wheels. When regarded this way many options become available for using the energy in those batteries for other purposes. This includes tradies recharging or powering their electric tools at a work site. When camping, lights, refrigerators, fans, heaters, ovens etc. can be powered by the EV battery.
However an outstanding use for an EV is powering a home at night when the home's solar panels aren't working. Fully charge an EV using solar power, drive to work and then come home and power the house at night time. There would be no need to buy extra batteries or a Powerwall to power the house.
The house could be powered for a number of days from the EV which is then recharged by solar power and the cycle starts again. Going off grid certainly is an option for a lot of people who live in areas where sufficient solar power can be produced in winter.
This article suggests scientists predict improvements in solar panel efficiency will allow people to go off grid in the future. Perovskite solar panels capture a broader spectrum of the sun's rays to produce more solar energy than traditional solar panels. This also applies on cloudy days or in winter. Conventional solar panels are about 23% efficient but laboratory tests have perovskite solar panels at around 33% efficiency.
The right infrastructure is needed for a person to use an ev to power their home. Expert suggest that a 10 kw solar system may be required. However there are people who are powering their house at times using their ev and this will become more prevalent over time.
Given the right infrastructure and sunny conditions the opportunities are certainly there to go off grid, and even doing it by using an EV as the battery storage device for the home. Even if this was just possible during summer it would certainly help lower the costs of electricity for the homeowner.
Alberta just had power problems because all the unreliable windmills and solar failed again due to a big snowfall.
What nonsense.
It's only common sense that a lot of people lack
„Scientists say …“ now has a completely different meaning
Germany are still 30% coal and lignite and only 10% solar as of 2022. There is also an indication the hybrids maybe the better option for countries like the UK.
In the U.K. it costs more in standing charge a day if your able to use solar
❤ Solar power
Sam is right. All while power campanies introduce new charges for peak usage with smart meters etc and governments do nothing to mandate electric vehicles connect to the grid power system. The grid seems doomed perhaps. There may not be enough participants to make a grid system worth while for the remaining people left using it.
In the sun belt, you can use water to cool the solar panels, to make them more efficient, and get better heating in the house.
The issue I have with solar is I can’t see a ROI. My annual bill is $1500.00. If I could reduce that to $500 saving $1000.00 a year and compare it with investing $20,000 at 5% I would break even. I know this doesn’t account for energy increases but it also doesn’t include any cost to repair or replace any equipment that may fail.
Especially in the sun belt,but a integration of AC and hot water in the same heat pump with storage for the heat and cold ,it will be chipper than battery and longer cicles.
My next home will be completely independent for electricity, water and sewage and I will use no fossil fuel (no gas for stove, heat, generator or vehicle) and I'm aiming for 80% independent for calories (I still love my chocolate and occasional banana and pineapple etc that don't grow where I live). Starlink for internet is about the only utility I plan on paying for. I will have no pipes or cables coming on or off my property.
I am 1 of them.
In NZ we cant get over cloudy rainy winter using solar alone...
In Australia 70% of dwellings are houses and the remainder are spilt approximately into townhouses and units so possibly 85% of us could have rooftop solar. I had no idea it was that high
This may be true of relatively low latitudes with sunny days of fairly constant length, but in higher latitudes with short winter days and cloudy weather PV only generates reasonable amounts of electricity in the summer. The grid will always be needed and wind rather than solar will be the mainstay for at least six months of the year.
billionaires make me sick
You mean jealous 😮
I am in the U.K., I have installed 45.2kw of panels connected to 107kwh of BYD storage I have been off grid since the last 2 weeks of March. Even with this absolute crap weather
@user-uk8tl3xy9e oh about £50k
Proves the point that its absolutely ridiculous to aim off grid with solar only when outside of the sun belt. You would still have to significantly increase the panel array and battery capacity to survive November, December, January and February. UK is not that north either, between 50 to 58 latitude. It gets way worse the higher the latitude is. Off grid system would be way over 100k $ investment.
Live in a house and get free electricity. Live in a polluted, crowded city and you will end up paying for the electricity you use and ALL the related generation and transmission infrastructure! As suburbanites and country folk leave the grid this will could become a death spiral for apartments.
It is something I want to do. if and when I get to solar panels, and batteries. Have it as a separate stand alone system. But retain the grid connection as well as back up. Probably a bit awkward and inconvenient but a transition safe way to move forward.
When you only get $0.49 in Australia to feed back to the grid, why wouldn’t you leave the grid?
Here in Michigan, it’s only 7 cents. The rate they charge is 20 cents. It makes cents to just use all your production wisely.
IMhO: The ongoing improvement in Batteries along side mass production and dropping battery cost will be a huge part of the folks dropping grid connections. I think for most solar wind water turbine alternative home energy systems ... currently benefit from using grid connection as their backup electricity for surge loads, and long periods of cloudy days. 🙂.
The good news in this is with bushfires. All the overhead wires in wooded roadsides are aging and causing fires. For a century or so this has been the case. With rooftop solar a lot of the overhead wires become redundant. Networks become short length and local. In the past Melbourne didn’t generate power at all. It all came from the Latrobe Valley on huge towers
And it was cheap and reliable.
England in winter 1600w of solar making as little as 8w😳
Running 20.5 kW of solar and a 13 kWh battery in Germany for two years now. Off grid would be an option from April to October. But what about the winter time? Also: my excess power during summertime would be lost when I go off grid. And that pays for the amount of energy I need during winter time. So actually I prefer staying on grid under the current conditions.
👍👍
Completely agree. Costs keep dropping and making this viable. I would do it myself.
The trick is to figure out how to do it without homeowner association objections and no increases to homeowner insurance premiums.
Look out !!!! Another self-taught electrical engineer!
LOL. My professional career was self taught (back when I started there were no college courses and not even books on the topic) and I did not get an electrical engineering degree, but I did get some courses on the topic in college.
But you don't need an electrical engineer degree to do solar. Nowadays it is more a matter of construction work than engineering. The rest is almost like Legos. Anybody with basic technical training, common sense and no vertigo can do it.
I think mismanagement of the grid and excessive energy costs is a HUGE motivation to leave the grid. Unfortunately, politicians in some areas make grid connection mandatory. It's extortion.
California is an example of how not to do everything. Terribly managed.
I am living in Austria, Tyrol. From March till the end of October I need no energy from the grid, including fully charging my BEV (EV6). 14kWp pv moduls, 28kWh battery, 12kW 3-phase inverter. From Nov. until the end of Feb. I have 70% solar power. Heating with fossil and wood.
Not sure about this. Here in the UK, even homes with solar and decent batteries still need the grid as a backup.
We also have a lot more people in apartments who will not see the benefit of solar - or EVs.
Solar panels are STILL not good or cheap in Canada... WTF
I’m expecting to see more states and counties pass laws or building codes(as some FL municipalities do) requiring homeowners to connect to the grid
And if you don’t use enough electricity (the generation part of the bill) the utilities will increase their transmission/distribution fee
500+ megawatts of solar is coming online in Arkansas this year
Instead of funding wars and US should be helping all Americans go solar. A am concerned about dealing with all the worn out panels.
Then those in control won’t profit.
I have a friend who works as an engineer for a national solar company. Current technology panels efficiency declines about .6% per year. They warrant 85% at 25 years IIRC. Once a panel farm is up and running, the only real major cost would be property ownership, mostly taxes. Unlike wind which needs new blades and perhaps more work at twenty years. And lots of concrete.
Let's say I'm wrong by a big margin and it's 1% per year. You are still at 50% efficiency after 50 years and all you do is nothing but pay property taxes. And maybe the sheep grazing around your panels pay that and more.
I don't think "the grid" is anywhere nearing the end of its usefulness. Solar can't do but a small percentage for an apartment building. It is also useful for geographical generating balancing. Wind here, solar dead there. But I can see the day when it is just a shell of its former self.
Thanks for your response.
Millions from 500 hundred millions is less than 1 percent. And there is good reason for that. For example, my roof sollar produces 450 kWh in june, but only ~10 kWh in december. No error here. 45 times less in december. When MWh size battery will be commonplace, I will consider going offline.
very interesting, devil is in the details, please provide a link to the report.
If we all start to use solar Aptera like cars, there will be enough grid energy to charge the remaining grid connected people. Multistory apartments are difficult to go off grid.
Australia is one of the leaders in the mass adoption of solar, grid storage and interconectivity between the grid and solar. The next few years will be pretty exciting to watch...
But if it fails we can't watch anything
In Qld watching Ergon charges triple the last ten yrs for us non solar panel homes. Looks like we are paying for any losses of consumption to power co, they will always make profit.
@@terryinozlandI’m in Australia too. Once Vehicle to Home (V2H) connectivity is simple, I think this will be a massive game changer. Those things are just huge batteries on wheels and at a much lower price than home batteries.
Rooftop solar is the absolute lowest c per kWh, it costs more to transmit and charge for the energy than if centralised generation was free.
At some point if the grid connectivity pricing gets too high, more people will question the value and turn it off to go off-grid.
I mean, $1-2 per day just to have the privilege of being connected is getting hard to justify. Once it gets near $3 the math is looking very interesting indeed.
@@dikkybee4003scaremongering at its finest.
Trying to scare people with that argument is hilarious. By all means, keep trying. The more you try, the more immune people get to it.
Especially in this channel.
Either help or get out of the way. Economics at scale will steamroll you regardless.
@@aaronsinspirationdaily4896^ this
I would like to. I have a 4.7 kw system now.
Why haven’t you bought batteries?
I live in Croatia and have very little system powering my ham radio station. And here are my numbers:
Maximum current: 1,2A
Curent for last 3 days: 0,08A
I know that numbers are low but scale it up if you wish. 120A versus 8A
So, I think you are wrong
Have you forgotten about the significant portion of the population who live in cities and other build up areas? What do they do to go off-grid when they don't have the land area to collect solar (e.g. share it with many others in high rise living). And when will we wee the first solar-pv powered aluminium smelter? Or producer of medication. Or cement works. Or many other producers of essential products at tight quality controls and cost-effective prices. We can't just turn those things off when the sun don't shine.
It stands to reason that as renewable tech advances more, it's going to allow a lot more of us to go gridless, and I suspect a lot of us will want to do that because it would be a simpler setup, and the savings will be direct to you, after all, for all the renewable energy going onto the grid, we as consumers don't seem to be seeing the savings in lower energy bills, so generating your own energy is a sure fire way for you to save over the long run.
To go gridless, renewable tech is already good enough, what is really needed is a buffer when it comes to storing that energy for when it's needed, and for now, it's too expensive and not enough energy storage, but thanks to EV car boom, that's very likely going to change.
Also, as the video points out, Europe isn't really a sunny region, well Northern Europe isn't, if they can do it, then the majority of the world can.
With that said, I do think a mix of solar and wind at a local level is a better option as they both complement each other by having more consistent energy generating throughout the year, which would actually reduce how much energy storage you need.
If it's solar alone, you're going to need a lot of energy storage to cover good and bad days when it comes to the weather, but if we can have a mix of solar and wind, that would be more constant and would reduce the amount of energy storage needed.
Problem is, there are too many scams when it comes to wind turbines for your home and they don't seem to produce that much energy, whiles also being expensive, but with that said, a lot of experiments are being made on vertical wind turbines for urban areas, if they can crack that and produce meaningful energy in urban areas, that's going to allow a lot of us to be able to go gridless, but even without that, solar is getting so cheap that it's making a lot of sense to oversize your setup, that yes in summer, you'll produce way more energy than you need, but who cares, just as long as you can produce enough for your needs in winter.
My house needs 55 kWh per day for electric heating and other use when it freezes minus 5C. How to harvest that energy with solar panels in winter, when it is dark and grey weather? No way possible with the present techniques.
Geothermal heating system can help with that if you have electric heat. I would also suggest putting in a wood stove.
Why are you using electric heat? I ask because it is the most inefficient for of heat.
@@waywardgeologist2520 A wood stove????? Suggesting that on this channel which is all about banning fossil fuels? Besides that efficiency of a wood stove? Not even considering poisening the neighbours? Wake up. 😁
It all starts with good insulation of the house. Agree that the winter season is a difficult one, with just solar panels to provide all the energy needed.
In Spain we were promised EU rebates, 24 months on no sign of it and no one I know has received it.
Well... you can't "leave" the grid. That would be illegal.
