Canada here. 7.6kw on our roof for $0 out of pocket thanks to $5k grant and $8k interest free loan.
It makes 7.72Mwh per year, worth $1000. Tight valley, tons of snow. We put that on the loan for 8 years, then get $1000 per year free money for 20 years or so. Biggest no brainer of all time.
Dad in Victoria Australia just got 10.6kw fully installed and operational for $4000 AUD. ($2,700 USD)
Australia has so much electricity during the day they’re talking about making I free for everyone in the middle of the day.

Energy is like RAM or clockspeed: you can't have enough of it.
Hasn't happened ever before, not sure why this time it would be different.
(still good news, as most of Canada's electric generation is low carbon hydro, and the rest of fossil generation can be pushed out with storage and renewables, although I do not have a link handy by province how much fossil generation needs to be pushed out)
If you have all of that expense, and suddenly people have solar panels so pay $0 for an energy bill - do you see the problem? The actual cost of fuel/generation is very small compared to the fixed costs.
The more people use solar, the more in the red the utility becomes. You can 'fix' this by making it so every home has a fixed 'connection cost' and then a smaller 'usage cost' on top, but that destroys the incentive for solar panels - they'd never break even for the average buyer.
Solar is great, fantastic even. But it should be done centrally, or people will have to get used to the idea that they will never pay themselves off and are just doing it for the environment.
Australia is giving free power to everyone during the day because they have so much.
More solar is a great thing.
> must be connected to the grid.
That's a legislative problem. If a home can prove it can produce enough electricity for itself, it should not be forced to be connected.
> You can 'fix' this by making it so every home has a fixed 'connection cost' and then a smaller 'usage cost' on top
A lot of places already do this.
Solar production in Canada will continue to grow, but we're not doing nearly as much as Europe to encourage it.
Made 6.9Mwh in 2025, only just less than ours with no shade at all.
Real numbers don’t lie.
https://www.sciencedirect.com/science/article/pii/S266675922...
(And a gazillion other studies.)
I think it's more frustration. Pointing out there is a maintenance cost to infrastructure is silly and doesn't add to the discussion.
We all know materials have to be shaped into machines to extract energy.
Lingan Generating Station would be a typical example. Big thermal power station, built to burn local coal, realistically the transition for them is to non-coal thermal power, burning LNG or Oil, or trees or whatever else can be set on fire. If they burned trash (which isn't really a practical conversion, but it's a hypothetical) we could argue that's renewable because it's not like there won't be trash, but otherwise this is just never going to be a renewable power source.
Canada is a huge place, so I don't doubt that none those coal stations are near you (unless, I suppose, you literally live next to Lingan or a similar plant but just aren't very observant) but most of us aren't self-sufficient and so we do need to pay attention to the consequences far from us.
Ontario, Quebec, BC and Alberta, the four largest provinces by population and a heady percentage of the land area, have zero coal power generation facilities.
Ontario is mostly nuclear supported by hydro, with an absolute fallback of natural gas. Quebec is overwhelmingly hydro + wind. BC is mostly hydro. Alberta is mostly non-renewables like natural gas, but phased out its last coal plants.
If someone is in Canada, odds are extremely high that there is no coal plant anywhere in their jurisdiction. I also wouldn't say that there is a whole bunch of coal power online -- they're an extreme exception now.
I haven’t touched ours, they are clean and have been going fine with zero maintenance, though admittedly it’s only been a year.
> Where are you getting this maintenance schedule from?
The solar panel owner does not know the required maintenance they are now permanently responsible for. Ibid, your honor.
Where are you getting this maintenance schedule of yours from?
Focus on solutions, not trying to be right. It’s aggravating.
> I've washed them once.
> I'm still getting great production.
Thank you for reiterating my point.
If you're in a place that gets significant snowfall such that they're often covered then production during winter is likely to be fairly marginal anyway, so may not be worth your while.
I will stand by your statement from the philosophical point of view that nothing in life is free and everything has its trade offs - but this is a pretty clear positive. In addition, Canada has pretty decent workplace safety enforcement for the sort of workers that'd be doing the maintenance - it certainly isn't perfect but it is something that Canadians seem to find important.
Zero maintenance.
I hope the incentives for cleaner energy continue to stack up. With the surge in demand from AI surely productivity will be more tightly coupled with energy usage and cost.

(at the rate it takes to deploy transmission, might as well start dropping TBMs in the ground and let them grind towards each other from interconnect landings, potentially faster than the approval grind, complaints from locals about land use and right of ways, etc)
https://ukerc.ac.uk/news/transmission-network-unavailability...
TL;DR - Until new interconnectors between Scotland and England are finished in 2029, there will be significant curtailment of Scottish wind power which increases costs.
This is also an interesting site for seeing curtailment per wind farm - https://windtable.co.uk/data?farm=Seagreen
Ideas crop up like generating hydrogen with the curtailed energy or maybe at least in Winter, use it for heat generation. The problem would seem to be the capex and the inverse of intermittency being the problem for them in utilising that energy, i.e. waiting for curtailment.
At least with available hydro you can pump water back up hill using a reliable and cheap tech.

FWIW - I am all for solar but selling rooftop solar in canada as cheap and no-brainer is false.
3-4 year payback would be a no brainer. 8-13 year payback with an inverter upgrade and op-costs is definitely a decision that needs to be thought out.
The grid you are offsetting is fairly green to begin with so the net benefit is marginal.
If you are going to be isolated and put backup power into the equation. You ROI tanks further but at least you have about a day or two worth of energy in the storage asset.
"How to cut U.S. residential solar costs in half"
https://pv-magazine-usa.com/2025/07/11/how-to-cut-u-s-reside...
Birch points to Australia, where he said the average 7 kW solar array with a 7 kW battery costs $14,000. That equates to $2.02 per W, with batteries included.
“You can sell it on Tuesday and install it on Wednesday, there’s no red tape, no permitting delays,” said Birch.
...
In the United States, that same solar and battery installation averages $36,000, said Birch. Permitting alone can take two to six months, and the cost per watt of a solar plus storage installation is up to 2.5 times the Australian price, landing at $5.18 per W.
Not just talking about it, if you get a smart meter and sign up for a plan that matches the grid rates you can actually be paid to take electricity during the day right now.
If you're wondering "couldn't you just make bank with a battery" yes you can. In fact Australia dominates the world in grid connected storage (per capita) and this chart itself is actually out of date (it's growing even faster than shown).
https://elements.visualcapitalist.com/top-20-countries-by-ba...
I'll also point out that gas and oil generation has declined rapidly.
https://reneweconomy.com.au/the-rise-of-battery-storage-and-...
For anyone that thinks renewables can't phase out peaker plants it happens very naturally and rapidly once there's enough solar to set rates negative in the day.
It would be worth including control of the people who vote for the politicians by direct investment such as when the oil producing Saudis bought the second largest stake in NewCorps which controls FoxNews controlling the content that influences voters. And, less than ethical control using bots on social media by Russia.
A lot of what influences "solar prices in the US" is controlled by foreign oil producing countries like Saudi Arabia and Russia controlling content and media consumed by American voters.
It's funny how “free markets” keep producing the most expensive solar prices in the developed world. Don't get me started on Healthcare (I just moved back to the U.S. a couple years ago after 18 years in Canada, what a cluster*ck).
Oil and gas buy politicians, foreign oil money buys media influence, and social-media bots keep voters angry at the wrong targets.
Saudi capital helps shape the messaging, Russia helps amplify the noise, and Americans get stuck paying more for clean energy while being told it’s patriotic.
But hey, Make America Great Again, right?
This very well may be true, but taken at face value Canada seems to be paying you around $7k to install solar panels on your roof (that's 8k interest free loan is losing out to inflation + any interest it would have earned).
Definitely a great deal if you own a home, if I was a renter/condo owner I'd be annoyed that everyone is subsidizing your free solar however.
As a non car owner are you annoyed everyone gets subsidized roads?
Are you annoyed corn farmers get subsidies for growing corn?
Would you be annoyed if people got subsidized life saving health care?
It feels like the US can’t have nice things because people are hell bent on others not having nice things.
What a shame.
Yes, and people should be annoyed by this given the underfunding, poor urban planning, and outright hostility by many local governments against anything that dares encroach on the sanctity of car culture.
What kind of selfish point of view is this? Don't you want people to use energy sources that are better for our entire world, even if it costs you like $10 more in taxes per year? Seems like a no brainer deal if you like "the outside" and you want it to still be there.
I'm a renter, been all my life, I'd be happy to pay more in taxes if it means more solar panels for everyone except me. But I also feel the same about elder care, health care and a bunch of other things, do you feel the same for those things too, or this is specifically about solar or owning vs renting?
You probably wouldn’t. I hear more people complaining about hypothetical government spending than actual government spending.
This has the same corrupt nexus with the anti-renewable mantra. Essentially subsidize oil and gas under the table and punish renewables then tell the electorate that the latter is worse than the former.
Instead of giving Americans free choice American automakers pay American politicians to prop up their uncompetitive prices and subpar offerings. All while they take in huge private profits. American workers could work on foreign automobiles, just as they do with other automakers not from China. It's not about workers, it's not about national security. You don't even have to go into all the environmental concerns that of course disproportionately affect poorer individuals.
It's corporate welfare. And yes, it should be criminal. At the very least, if the American people are going to inflate CEOs salaries they should have seats on the board.
This is actually not a wild idea. You might be surprised to find who one of the largest shareholders of the Volkswagen group is. It's not like that is an obviously mismanaged socialist hellhole company, it's a perfectly competitive and well regarded car company.
Americans need to start demanding more equity or oversight in operations their governments are already paying for. The fact most Americans think this amounts to communism just means more people have to call out the money is already flowing.
€13.000 for this still seems expensive.
Are there tariffs on Chinese PV in Canada?
Also, Trump called out the idiotic decisions by greenies such as shutting down nuclear power plants and make long your industries less competitive as a result.
The shift to renewables started off pretty well in the early 2010s before it came to a grinding halt thanks to some wierd debates around the topic. For the past few years, buildout of solar has been remarkably fast, especially considering the slow pace of other projects. In 2025, 16.4 GW of solar power went live.
The biggest issue that drives prices here is the grid. New high voltages transmission lines have faced intense local oppsition, so transmision between North and South is limited, which is problematic given the focus of the north on (offshore) wind and the south on solar PV. Since Germany is a single electricity price zone, the low to negative electricity prices from wind turbines do not reflect the reality of grid capabilities, resulting in significant redispatch costs.
The solution would be obvious. Split Germany into n electicity price zones (with n>1). However, there is a lot of political opposition, specifically from the conservative CDU/CSU against this.
So yeah, Germany is struggling with relatively expensive electrcity prices, complaining about it, but refusing to implement a borderline free solution for it.
My weekly supermarket shop for the basic essentials (cheese, eggs, flour, vegetables) now come to around $60/80 a trip.
Pamantasan Cheese is around ~£22-£45 ($30-$60) per kg compared to the US $7–$24+ per kg.
Just because we've got, if the government isn't supporting it's pretty much wasted. The renewable farms we do have are mostly funded by private investments firms. Scotland and Wales wants more renewable but the UK government says no.

What is stupid about nuclear? It's a huge amount of clean, secure energy.
Would your preference be dependence on Russian/US oil natural gas? Would you feel the same if Russia invaded Finland/Baltics and US took over Greenland?
It's not the stupidly of the reactor producing. I don't agree with it personally, but hey whatever.
The stupidly of it is that we are small island. Claim what you wish about how safe they are but malfunctions can still occur. Cyber sabotage and all that. If a reactor was to implode we're eff'd. Besides that we don't have landmass to facilitate the output waste in the UK. The waste we do produce has to be shipped elsewhere, sold for dark money.

Conservatives, sponsored by oil and pharmaceutical. Exxon, Esso, BP et cetera. They got their wish with Brexit, they made a bucket load of cash from that and they're the ones who scrapped the renewable industry in the first place.
One of their aims is to scrap the NHS and make it privatized and give tax reliefs to the filthy rich.
No it doesn't. Maybe if you are shopping at Waitrose. It is more expensive. But it isn't £45 for basics. I did an entire shop which will last me the week for £30 (in Aldi).
Everyone has their super market preference. ASDA would be cheaper still, but you can't disagree that prices haven't sky rocketed and shrunk in quantity,
No. Citation neede. The issue is the moronic way energy auctions are done, first by setting the price to the highest source that can satisfy (always gas) but ignoring (!) geography. Then, phase 2, dropping the impossible providers (i.e. Scottish hydro in the North for South England), and doing another (much more expensive pass). The Octopus CEO had a succinct explainer recently, can't find the video...
Found it: https://youtu.be/5WgS-Dsm31E?t=91 starts at 1:31
Energy is not expensive because of Net Zero taxes. Here's a breakdown of the average UK electricity bill over time [1]. The Renewables Obligation, that subsidised wind and solar at a time when they were infeasible without subsidies, was a scheme that ran between 2002 and 2017. It was stopped once renewables became cheaper than the alternatives. We will continue to pay for the renewable plants set up back in the day, but this will gradually taper off. In this electricity bill estimate for 2030 [2], you'll find that the Renewables Obligation is much lower (£17 rather than £102) for two reasons: plants losing subsidies as they age out and a chunk of the subsidy being borne by the treasury from general taxation.
So why aren't electricity bills coming down? Because we're recognising the reality that we will need to be powered by a mix of nuclear, wind and solar. Check out this real time dashboard of electricity generation in the UK [3], which shows you how Wind has zoomed in the last 14 years. From 2GW to 14GW, wind is now the single largest source of energy generated in the UK.
Wind is only going to grow, because it is cheap compared to the alternatives. In the Jan 2026 auction for wind power, an 8.4GW contract was awarded for a price 40% lower than the cost of a gas power plant. And unlike gas you aren't at the vagaries of global gas prices, like we were in 2022.
And now you're thinking, if wind is so cheap and we're continuing to build more, why is the estimate for the 2030 electricity bill higher than 2025? The 2030 page explains this - the wind is being built in the North Sea, far from where it is needed - in the South of England. This means investing in the transmission network, which will cost £70B over the next 5 years. That cost will be passed onto consumers.
So no, bills aren't high because of renewables. The decision to double down on wind, solar, batteries and nuclear by the previous and current government are sound. We will be more energy independent than we were in 2022 and possibly paying a bit less in overall bills. The reduction in carbon emissions is a nice bonus.

(As an aside, I'm from Groningen/NL :))
This time, however, it looks like it's actually true and that's just for wind and solar. This is incredible, and done through slowly compounding gains that didn't cause massive economic hardships along the way.
It’s still a great trend.
Electricity/heating and gasoline in the EU is many times more expensive than in the U.S., and as a result EVERYTHING is more expensive.
Mix that with lower buying power and taxes and we spend 2-3 times for stuff.
I would think that most people would happily choose lower prices over clean energy and paper straws.
Our companies are also less and less competitive because of these initiatives, and companies from China take over in part thanks to the complete lack if environmental and labor laws over there.
Seems to me like this is happening more and more, and it's so widespread and obvious that it almost makes you think that politicians are being bought by Chinese companies/government.
What are oil companies doing to drive European companies out of business (not saying they aren't, I just don't know)?
Maybe because Europe as a whole has little to no signifcant oil reserves ready for extraction? Very much unlike the US.
> I would think that most people would happily choose lower prices over clean energy and paper straws.
The US does have plenty of cheap energy and yet its industrial output is dwarfed by Chinas, which is increasingly relying on domestically products green tech. Also, people seem to be not very concerned with energy prices. If they were, they would not act as irrational when it comes to topics like heatpumps or electric vehicles.
> that it almost makes you think that politicians are being bought by Chinese companies/government.
Looking at the energy policy of some countries (Germany specifically), it seems vastly more likely that politicans are bought by oil companies.
That's interesting about oil companies. Is that who's lobbing to pass laws that just seem (to me) to be written on purpose to make our companies less competitive? How does that work, how do oil companies profit from that?
For instance, the rising prices of carbon permits under the EU emissions trading scheme.
So, my point is that countries that don't ignore the economy just to be green--like the U.S. and specially China--seem to have vastly cheaper electricity and gasoline, which I would guess makes them more competitive/lowers prices.
Over here we have no NG and no oil, and on top of that we tax our companies because of emission limits, while in China they burn coal like there is no tomorrow.
We wanted to outlaw non-electric cars, while the car industry in Europe is huge and we don't have a way to build batteries, etc. etc.
Seems to be a pattern that is hard to understand.
Nowadays, for very energy intenive things like heating or driving a car, fossil fuels still are more prevalent than electric alternatives. Once demand shifts in favor of the electrified alternatives, electricity demand is continuing to raise (although not as steep as the drop in demand for the fossil fuels will be). Particularly in heating, where peak demand is in times with very little solar generation, it seems like this will be challenging.
While the prices of energy storage have come down significantly and are projected to continue to drop, there is still a noteable lack of cost effective long term storage solutions.
* Distance travelled by passenger cars in Norway
* EV electricity consumption and total power generation in Norway
EVs now make up approximately 1/3 of miles travelled, but the increase in total electrcity consumption is fairly small.
Heating is actually likely to be one of the easier questions here, because heat is just fundamentally an easier problem to tackle than most other intensive uses of energy in the modern world.
1. Solar isn't the only incredibly cheap form of intermittant renwewable energy production. Wind is also great, tends to support local manufacturing economies more than solar, and is anti-correlated with peak-sunshine. The wind tends to blow hardest in the winter and around sunset.
2. Heatpumps can pretty comfortably achieve 300+% coefficients of performance, meaning that for every joule of energy you put into a heatpump, you'll get 3+ joules of heat pumped into your home, office, or city-scale heat thermos
3. Heat energy storage is cheap compared to batteries. You just store large quantities of hot water or sand with a resistor or a heat pump. 3D geometry ensures that the bigger you make the heat-battery, the less energy you'll lose from it over time (percentage wise).
4. Heat is a waste product from many other forms of energy usage, and can be harnessed. For instance, gas peaker plants aren't going away any time soon, and cities which aren't harnessing the waste heat from those peaker plants and using it in a district heating system are wasting both money and carbon.
Just a couple kilometers from my home for instance is a gas power plant that stores waste heat in giant thermoses, and pumps hot water to my building to to be used for heating. They currently have the largest heat pump in europe under construction on the same site intended to supplement the gas plant, both to take up slack from the fact that it'll be running less often, and to expand the service to yet more households.
The next milestone to watch: when battery-backed solar becomes cheaper than gas peakers for evening demand across most of Europe. We might be closer than people think.
Fossils are dead, slow.
Wind moves fast. Photons move even faster.
See: the overly optimistic SMR plans being predictably scrapped in many places.
What you do have is ample land to build out solar and export eg. Ammonia (made out of Hydrogen) for "free" energy.
Edit: After further reading it appears that solar will be the defacto affordable option in energy production, even with SMRs and streamlined construction in the picture. Perhaps a mix of renewables, better battery infra, and SMRs for stable sources of power is the future.
He argues that because solar and wind are now the cheapest forms of new energy generation, they are on an unstoppable exponential "S-curve" that will make coal, gas, and nuclear power obsolete by 2030.

China wants Russia to at least keep the Ukraine war going, if not eventually win the darn thing.

And as long as we are distracted with Israel/Palestine or Ukraine/Russia, China has free rein to do whatever they want.

Economical co-dependency is a good tool for increasing the price of going to war and making it irrational. It’s also not a zero sum game and tends to profit both sides. However, it can suck if you do it with non-democratic regimes and autocratic rulers who trample human rights.
So between France, Germany, Poland and all the other EU members it‘s keeping the continent at peace and generally does not suck because it‘s between broadly democratic nations. It also benefits each one massively and makes things possible like a common electric grid that increases reliability in general. So nearly all upside.
I do think economic cooperation with the Soviet Union and later Russia - much, much more limited than between EU members - was helpful in cooling tensions and making the world a bit safer, sure, but Russia has clearly behaved in a way that makes that no longer a good idea.
