It’s kinda good but it completely destroyed the European manufacturing for solar
When panels were 30c/watt, projects at $1/watt in EU and US happened. 70c/watt was spent on labour, copper, support structures, and grid connection equipment. All of those can be locally produced, with possible exception of last item.
At 6c/watt, that is over 90% of power projects are local economy boosting instead of 70%. It provides cheaper energy that is useful for industrialization and cost of living benefits too. US tariffs on solar are entirely about protecting oil/gas extortion power instead of a $10B solar production industry that needs fairly expensive support.
Solar imports does not cause energy dependence. You have power for 30+ years with no reliance on continuous fuel supplies. Shoes and apparel is a $450B industry in US. You need new supplies every year, and it makes much more sense to secure supply in that industry for war on the world purposes.
By providing big subsidies to green energy developement. Something the EU could also have done but refused to. And so they lost their entire lead.
You’re either an astroturfer or useful idiot spreading oil lobby talking points.
Either you believe the climate science or you don’t. If you do, you know that we don’t have time for industry protectionism.
It is good, period.
Local manufacturing is politically advantageous and may employ some people at the same time, but that’s where benefits end.
Europe didn’t reject Chinese face masks during COVID-19, and Europe shouldn’t reject Chinese solar during a climate emergency.
Solve that first, and political struggles later.
It’s not only a political struggle. Working conditions are tremendously better in Europe, Environmental Protection as well. Manufacturing photovoltaics takes a huge pile of chemicals that need to be handled properly to not cause any harm to the environment - China neither cares nor has any other incentives to actually do this properly, which is exactly why they are so cheap. Theres also the issue of poor quality, that if you’re manufacturing something that can have a significant impact on the environment, it should “count” and not be waste 10 years later.
Not only that, China’s subsidies are utterly unfair.
Destroying the environment in one part of the world to “save” a different one due to climate change is just ridiculously stupid and simple minded.
Manufacturing photovoltaics takes a huge pile of chemicals that need to be handled properly to not cause any harm to the environment
Source for this? Cadmium is exclusive to 1 US manufacturer.
Yep the EU will be beholden to a dictatorial regime again. Instead of placating Putin for gas it will be Xi for solar panels and batteries.
At least those items you only need to buy once.
What? Have you ever had a battery powered device for longer than 2 years?
All of them, plus storage batteries are under much less abuse and are different chemistry that lasts a lot longer.
I didn’t mean they only last 2 years but battery degradation is a pretty common and known thing.
By a quick search I didn’t find any claim of storage battery lifetimes outside of 10-15 years, so there doesn’t seem to be a breakthrough in tech I wasn’t aware of. 15 years is hardly the lifetime of a house, so you certainly don’t “buy only once”.
Solar panels also don’t work indefinitely but their efficiency degradation is more on par with the lifetime of major parts of the building, like the roof itself.
Theyre $1.25 per watt in south America right now (we have an energy crisis due to climate change caused drought)
Solar has always an extremely high ratio for megawatt per mass unit.
This price is really good
Here in Belgium there used to be big government subsidies for solar panels 5-10 ago.
Now the same wattage battery + solar setup without any government subsidies is a good chunk cheaper than that time with the large subsidies.
Pretty cool and shows the power of government renewables subsidies. A huge percentage of houses in Belgium have solar panels now.(and electricity still costs 0.30€/kWh average because of fossil fuel energy lobbies)
Now that there is a local industry around it, most renovations and almost all new builds include them.
electricity still costs 0.30€/kWh average because of fossil fuel energy lobbies.
This is the price of guaranteed electricity delivered to your doorstep. We can’t get rid of gas fired power stations and kms of electricity grid network yet.
As your northern neighbors. We did subsidize it too, but now the privatized energy companies started whining that there wasn’t enough capacity, so now they charge you for creating free energy
Yes I’m considering buying a high power laser so I can send the energy back into space instead of paying the power companies for the privilege of giving them electricity.
Great idea! Some inspiration right here :
I’m fairly sure that all newly built houses in the UK require solar by law.
All the new houses around here with no solar would indicate that is not true. They’re not even required to have a south facing roof.
Same here in California
It is very poorly implemented. “Builder grade” solar panels in a “smallest compliant” configuration with no concern for architecture to benefit from solar takes place. Builders are intentionally putting the shittiest solar to reduce value of the homes they build so that they can complain about the policy.
4 million households in Australia have solar panels.
They are great value.
Just have to buy 1100 panels 😋 but then the price is 0.055€/watt …
I Want one, but only one or a couple, to put on my balcony…
Thousands of people buying rooftop panels was never going to be the best way towards a Water/Wind/Solar (WWS) future. Fitting panels to the roof has to work around the roof geometry and obstructions like vents. That makes every job a custom job. It also means thousands of small inverters rather than a few big ones.
Compare that to setting up thousands of panels on racks in a field. As long as it’s relatively open and flat, you just slap those babies down. You haul in a few big inverters which are often built right into shipping containers that can just be placed on site, hooked up, and left there. Batteries need inverters, too, so if your project includes some storage, then you only need one set of inverters.
I get the feeling of independence from the system that solar panels on the roof gives people, but it’s just not economically the best way to go. The insanely cheap dollars per MWh of solar is only seen when deploying them on a mass scale. That means roofs of commercial/industrial buildings or bigger.
These are topcon modules only. Considering a 400W panel will have about 72 modules in it, that’s only about 15 panels worth. Of course, then you have to actually build the panel and connect the modules, put it behind glass inside a frame, then put in a bypass diode and leads for connection. So an actual panel ends up being about 5-10X the cost of the modules per W.
You can pay a lot less than 10x for completed panels. https://store.santansolar.com/ amazed me.

$60k per MW or $210M for a nuclear reactors worth (3.5GW). Sure… the reactor will go 24/7 (between maintenance and refuelling down times, and will use less land (1.75km² Vs ~40km²) but at 1% of the cost, why are we still talking about nuclear.
(I’m using the UKs Hinckley Point C power station as reference)
We can’t manufacture and install enough solar farms and storage to get us off of fossil fuel within 20 years and more importantly available investment capital isn’t the limiting factor.
Investments in nuclear power are not taking money away from investments in solar.
We can do both, and it gets us off fossil fuels sooner.
Total solar manufacturing capability has been increasing exponentially. So has wind, and so have various storage methods.
Yes, we can install enough.
Also the budget and timeline is always understated, because otherwise government could withdraw funding if they don’t sink a little more cost into the budget every year.
but at 1% of the cost, why are we still talking about nuclear
Sure… the reactor will go 24/7 (between maintenance and refuelling down times, and will use less land
The land thing isn’t anywhere near enough of a concern for me, especially when dual uses of land are quite feasible.
24/7 is just about over commissioning and having storage. Build 10x as much and store what you generate. At those sorts of levels even an overcast day generates.
Using the remaining 99% of the cost to bury batteries underground would seem reasonable.
Batteries can be containerized in modules, with a turnkey connection that remains mobile. Solar can use those containers as support structure. Hydrogen electrolyzer/fuel cells can also be built in same containers.
Because grid level power delivery is about FAR more than just raw wattage numbers. Momentum of spinning turbines is extremely important to the grid. The grid relies on generation equipment maintaing an AC frequency of 60 hz or 50hz or whatever a country decides on. Changing loads throughout the day literally add an amount of drag to the entire grid and it can drag the frequency down. The inverse can also happen. If you have fluctuating wind or cloud cover you can bring the whole grid down if you can’t instantly spin up other methods to pick up the slack.
reliable consistent power delivery is absolutely critical when it comes to running the grid effectively and that is something that solar and wind are bad at
Ideally we will be able to use those technologies to fill grid level storage (batteries, pumped hydro) to supply 100% of our energy needs in the not too distant future but until then we desperately need large, consistent, clean power generation.
You aren’t wrong, but you are assuming that the grid is required. Solar panels can be installed at the point of use, and then the grid doesn’t come into it at all.
Because there are nights there are winters there are cloudy and rainy days, and there are no batteries capable of balancing all of these issues. Also when you account for those batteries the cost is going to shift a bit. So we need to invest in nuclear and renewables and batteries. So we can start getting rid of coal and gas plants.
The batteries needed are a lot less than you might think. Solar doesn’t work at night and the wind doesn’t always blow, but we have tons of regional weather data about how they overlap. From that, it’s possible to calculate the maximum historical lull where neither are providing enough. You then add enough storage to handle double that time period, and you’re good.
Getting 95% coverage with this is a very achievable goal. That last 5% takes a lot more effort, but getting to 95% would be a massive reduction in CO2 output.
Also when you account for those batteries the cost is going to shift a bit.
You better be bringing units if you’re going to be claiming this.
Still less than half of the LCOE of nuclear when storage is added: https://www.statista.com/statistics/1475611/global-levelized-cost-of-energy-components-by-technology/
Given that both solar and storage costs are trending downwards while nuclear is not, this basically kills any argument for nuclear in the future. It’s not viable on its face - renewables + storage is the definitive future.
And cheaper solar and batteries permits cheaper Hydrogen which provides unlimited and 100% resilient renewable power, and still cheaper than nuclear.
You’re using factors of less than 10 to argue against a factor of 100.
But Germany has no space for nuclear waste. They haven’t been able to bury the last batch for over 30 years. And the one that they buried most recently began to leak radioactivity into ground water.
And… why give Russia more military target opportunities?
I’m not a rabid anti-nuclear, but there are somethings that are often left out of the pricing. One is the exorbitant price of storage of spent fuel although I seem to remember that there is some nuclear tech that can use nuclear waste as at least part of it’s fuel (Molten salt? Pebble? maybe an expert can chime in). There is also the human greed factor. Fukushima happened because they built the walls to the highest recorded tsunami in the area, to save on concrete. A lot of civil engineering projects have a 150% overprovision over the worst case calculations. Fukushima? just for the worst case recorded, moronic corporate greed. The human factor tends to be the biggest danger here.
there is some nuclear tech that can use nuclear waste as at least part of it’s fuel
Those are less competitive, and salt reactor attempts have historically caused terminating corrosion problems. The SMR “promise” relies on switching extremely expensive/rare/dangerous plutonium level enriched fuel, that rely on traditional reactors for enrichment, for slightly lower capital costs.
Not an expert, but molten salt reactors are correct. MSRs are especially useful as breeder reactors, since they can actually reinvigorate older, spent fuel using more common isotopes. Thorium in particular is useful here. Waste has also been largely reduced with the better efficiency of modern reactors.
Currently, Canada’s investing in a number of small modular reactors to improve power generation capacity without the need to establish entire new nuclear zones and helps take some of the stress off the aging CANDU reactors. These in particular take advantage of the spent fuel and thorium rather than the very expensive and hard to find Uranium more typically used. There’s been interest in these elsewhere too, but considering how little waste is produced by modern reactors, and the capacity for re-use, it feels pike a very good way to supplement additional wind and solar energy sources.
If France can find space, surely Germany can.
If Finland could find space, Germany definitely can.
Finland with it’s vast swathes of frozen tundra.
We don’t have vast swaths of Frozen Tundras. This isn’t Alaska.
And it’s actually stored south not north.
Idk, Finland has a much lower population density vs Germany. France is something like 1/2 the population density, but they also have >50 reactors, so surely Germany can find room for a few…
Finland smaller tho.
- Finland: 338,145 km² and 5.6 million people
- Germany: 357,596 km² and 82 million people
Where do you want to put your hazardous waste again?
Yup, but population density should be what matters, because that implies how much usable space there is for waste disposal.
And Sweden.
I think there’s a contingent of people who think nuclear is really, really cool. And it is cool. Splitting atoms to make power is undeniably awesome. That doesn’t make it sensible, though, and they don’t separate those two thoughts in their mind. Their solution is to double down on talking points designed for use against Greenpeace in the 90s rather than absorbing new information that changes the landscape.
And then there’s a second group that isn’t even trying to argue in good faith. They “support” nuclear knowing it won’t go anywhere because it keeps fossil fuels in place.
What isn’t sensible about nuclear? For context, I’m coming from the US in an area with lots of empty space (i.e. tons of place to store radioactive waste) and without much in the way of hydro (I’m in Utah, a mountainous, desert climate). We get plenty of sun as well as plenty of snow. Nuclear should provide power at night and throughout the winter, and since ~89% of homes are heated with natural gas, we only need higher electricity production in the summer when it’s hot, which is precisely what solar is great for.
So here’s my thought process:
- nuclear for base load demand to cover nighttime power needs, as well as the small percentage of homes using electricity for heat
- solar for summer spikes in energy usage for cooling
- batteries for any excess solar/nuclear generation
If we had a nuclear plant in my area, we could replace our coal plants, as well as some of our natural gas plants. If we go with solar, I don’t think we have great options for electricity storage throughout the winter.
This is obviously different in the EU, but surely the nordic countries have similar problems as we do here, so why isn’t nuclear more prevalent there?
Because it makes no sense, environmentally or economically speaking. Nuclear is, as you said, base load. It can’t adjust for spikes in demand. So if there’s more energy in the grid than needed, it’s gonna be solar and wind that gets turned off to balance the grid. Investments in nuclear thus slow down the adoption of renewables.
Solar is orders of magnitude cheaper to build, while nuclear is one of the most expensive ways to generate electricity, even discounting the waste storage, which gets delegated the the public.
Battery technology has been making massive gains in scalability and cost in recent years. What we need is battery arrays to cover nighttime demand and spikes in production or demand, combined with a more adaptive industry that performs energy intensive tasks when it’s abundant. With countries that have large amounts of solar, it is already happening that during peak production, energy cost goes to zero (or even negative, as traded between utilities companies).
About the heating: gas can not stay the main way to heat homes, it’s yet another fossil fuel. What we need is heat pumps, which can have an efficiency of >300% (1kWh electricity gets turned into 3kWh of heat, by taking ambient heat from outside). Combined with large, well-insulated warm-water reservoirs, you can heat up more water than you need to higher temperature during times of electricity oversupply, and have more than enough to last you the night, without even involving batteries. Warm water is an amazing energy storage medium. Batteries cover electricity demand as well as a backup in case you need uncharacteristically much water. This is a system that’s slowly getting adopted in Europe, and it’s great. Much cheaper, and 100% clean.
We also should consider HVDC lines. The longest one right now is in Brazil, and it’s 1300 miles long. With that kind of range, wind in Nebraska can power New York, solar in Arizona can power Chicago, and hydro all around the Mississippi river basin can store it all. We may have enough pumped hydro already that we might not even need batteries, provided we can hook it all up.
You bring up heated water as a method of storage, and it reminds me of a neighborhood in Alberta, Canada that uses geothermal + solar heated water storage for 52 homes. They’ve been able to successfully heat the entire neighborhood with only solar over the winter in 2015-2016 and have gotten > 90% solar heating in other years.
https://en.wikipedia.org/wiki/Drake_Landing_Solar_Community
There’s a huge number of new storage technologies being developed, and the fact that some even work on a seasonal basis for long term storage is amazing.
That’s pretty cool! Still seems to have some issues, but as the technology matures, that seems like a promising technology. I didn’t know seasonal warm water storage was a thing
I’m very much in the first camp and need to remind myself whenever I think about arriving due nuclear
A MW of solar averages out to about .2 MWh per hour. A MW of nuclear averages about .9 MWh per hour.
But even so as the UK does it, nuclear power isn’t worth it. France and China are better examples since they both picked a few designs and mass produced them.
China’s experience indicates you can mass produce nuclear relatively cheaply and quickly, having built 35 out of 57GW in the last decade, and another 88GW on the way, however it’s not nearly as quick to expand as solar, wind, and fossil fuels.
Maybe just use percentages instead of these weird units. 0.2 MHh per hour is just 0.2 MW, or 20%.
It seems easier to say solar produces an average of 20% of it’s peak capacity.
MW/h
There is MW which is a unit of power and then there is MWh which is a unit of energy, but what is MW/h supposed to mean?
Thanks for catching the typo.
Nuclear actually around 0.6, because 1/3 is always off for repair and control.
Maybe in the UK where each plant is basically unique instead of having improvements from all the previous iterations. In the US it’s around 93%. I don’t know how to search China or France’s numbers, but I suspect they’re similar or better.
You have to have some base load it can’t be all renewable because renewables just aren’t reliable enough. The only way to get 100% reliability from solar for example would be to build a ring of panels around the equator (type 1 civilization stuff).
Of all the options for base load, nuclear is the least worst, at least until we can get Fusion online, but you know that’s always 20 years away.
Storage. It’s all about storage. In exactly the same way that our water is handled. We have reservoirs to handle the times when natural water supply is low.
That’s why we have hydro. Its a giant battery. We can also make synthetic methane.
We absolutely can do 100% renewable.
Hydro is great but it’s not clean it requires you to flood vast areas of land, it’s quite damaging to wildlife.
It is also highly situation dependent, you be quiet exactly the right kind of geography in order to be able to build hydro and then you require that there is no one living in the affected area otherwise it gets very expensive very quickly assuming you’re allowed to do it at all.
I didn’t say hydro is perfect. It is renewable. And its a giant battery.
Hydro is kinda awful for the environment.
Better than fossil fuels
deleted by creator
Good news perhaps but I’m sure I won’t see any benefit in Scotland, still thousands to add solar panels.
Scotland has really good wind power, anyway. Between that, nuclear, and a few other renewable sources, you guys are down to 10% fossil fuel energy use. So don’t worry about solar.
You know, if you people wanna ditch the Kingdom and join the club, I don’t think it’s too late.
Yup. Average here in south US is 25k for a home system without battery backup.
For electricity generation: Solar across the UK was about 5% in last year, while Wind was about 29% and Nuclear 13.9%, and hydro 1.3% - so 49.2% of electricity generation over the last 12 months was carbon neutral.
That’s a huge success story - still a long way to go, particularly as that does not include Gas burned in homes, but the UK is moving in the right direction. And Scotland is a huge source of Wind & Hydro power for the whole country.
So even if the barriers to solar in your home are still high, the grid is getting cleaner and cleaner every year. There are also community projects installing wind generators which you can join/invest in if you do want to try and get a slice of cleaner energy and solar is not realistic.
Edit: Source on UK electricity generation: https://www.energydashboard.co.uk/historical Good data on UK electricity generation
Installation the trouble. Roofing is expensive. Next time you have to redo the roof: then it’s time
Assuming these prices are ideal for a solar grid, which EU country(s) would have the highest chance of shifting towards solar; I wonder
Probably all of them. Germany is really not ideal for solar in terms of weather, yet they are installed by many people all over the place, even today. With the cheaper prices things will get even better.
Germany is already over 50% renewable. :)
Any good store that will sell me a super cheap and good set including inverter here in Germany? I mean they’re on Amazon for 250€, but maybe there is a better shop?
Any of the Discounters, really. ALDI, Lidl, Netto, etc have regular offers in their online shops.
Hmm. But with those three, the simple sets (2x400W + power inverter) seem to be ~100€ more expensive than on Amazon. Maybe I have to go with Amazon then. Thanks anyways! I’ll keep an eye on discounted offers.
A hundred euro is quite a difference. Didn’t expect it to be that much, tbh.
The only consolation is that, with the discounter sets, you will get something that has been tried and tested and everything is according to the relevant technical standards. Should be, anyway.
