[@frenchydampier2209]

I live in Northern America., we gained power by using bi-facial vertical panels. Oriented east-West instead of south facing.. In the winter there may be almost a month with clouded sky’s and no direct sunshine. In addition snow may build up on the panels. By going vertical panels avoid snow covering. And because both sides gather light reflected off of snow. Further vertical panels collect early sunrise and late sunset better. While not overheating the panels ( and reducing output ) during midday because sun at noon is shinning on the edge not the face. Meanwhile reflected sunlight is charging both sides of the panels.

[@andrewallen9918]

Over 12.5 years ago we installed PV; the panel efficiency was 19%. Yes, they were at the top end but unfortunately panel efficiency clearly hasn't doubled in that time, not even close. 23-23.5% non perovskite panels already exist in the market at relatively low cost so 24.5% isn't a great leap forward. I'd be interested to know how perovskite compares to existing panels in terms of cost/kW. I've been following perovskite for several years and lifespan has been the core issue. Hopefully now that we're seeing commercial installations they continue to improve on the efficiency and durability.

[@TimMountjoy-zy2fd]

Since 2010 we have added about 3% per year to PV efficiency and it feels like that as we slowly moved from around 15% to 22% currently. Interestingly Panel prices have dropped 8% per year. So 5% of that 8% has come from the 1000+ little innovations that come in mass manufacturing and synchronising supply chains (A Chinese Speciality). So these panel could be the first time we actually make a jump forward rather than incremental progress.

China will reverse engineer this and essentially start mass producing this by the time Oxford get around to their mass production. Your video mentioned YEARS before they scale production. Who knows what tech advancements will come in that time.

1:13 "Oxford have increased the efficiency by a further 20%." - in relation to what? That shold've been mentioned up front. I thougt they came up with an extra 20% of the solar power potential here on Earth, which would've been indeed revolutionary - going up to 40-45%. Anyway, one big issue with perovskites was the fast degradation of the solar cells. It would've been nice to touch on that topic and tell us what they've come up with for the production version of their panels. Maybe they achieved a _"good enough for now"_ durability, but I doubt they're anywhere close to the currently installed panels, which last for decades. Hopefully they got a lot better than they were just 1-2 years ago. Otherwise the bang for buck is still not there. P.S. I checked, and their press release from September 5th doesn't mention durability at all. These panels may be great for utilities who recoup their investment before the panels degrade, so it makes sense they're interested. For home owners who want to use them over the long term, it's unsure they're at the level required for a reasonable return on investment.

Suggest you explain WHY your house is cooler when PV is on roof- some know, some will wonder, it is a huge, free, advantage IF the air between the PV and roof is let to escape on its own, for example, on a pitched roof or many inches above the existing flat roof.

[@WJV9]

I think it is self explanatory that solar panels on a roof will shade the original roof and block the solar radiation from heating the roof and attic of the home. Of course all solar panels have to be mounted on rails about the roof a few inches to allow rain to drain normally down to the gutters. I don't like the idea of drilling holes in a roof to mount solar panels as that will set up a possibility of water leaking when wind pushes and pulls the solar panels and causes roof fasteners to loosen.

[@MarcoNierop]

@3:42 STARLINK! Awesome installation dude! I have 14 solar panels on my roof since 2014, they have a 275Wp rating, I bet your panels of the same size have a 450wp rating, right? almost twice the capacity. I have added an Enphase 1Q Battery 5P last week, and my house is at time of writing running on battery power! Making me even more independant of the grid. So during the night it runs on the battery, but early in the morning it charges up in just 2 hours back to 100% Maybe in a few years I will replace the solar panels with new ones with higher rating, if these Perovskite panels become available at cheaper prices, that would be awesome, but then probably a new converter is necessary as well, or just add one to the existing one, I don't know, we will see. Then I will also start charging my Tesla Model Y with my solar panels, right now that is not possible yet as I can not park my car in my front yard, I need a permit for that.

27%? They're not that high, not yet at least. 24.5% was quoted for the commercialised perovskite so not much higher than existing commercial panels and the degradation rate is unproven.

[@elduderino7767]

from 20% to 26% is quite a jump but at the end of the day it always comes down to cost, if it's only about 50% more expensive then great, for a small premium you can increase the power density of your solar array but if it costs twice as much then just use old tech and throw on an addition panel or 2 to get the same power capacity ultimately the tech (or a derivative of it) will need to be mass produced by competitors for it really get market adoption - only then will it change the game imho

Grid blindness, it's sunk cost and ROI is overlooked in most people's thinking. The grid has to run more fossil fueled peaker plants. With more battery capacity, they will have to turn off more nuclear plants. I have been told that it has happened at a big Canadian nuclear power plant now. Just one unit, but it may be the beginning in other provinces or states. Hydro can respond fastest. Government is under heavy pressure to maintain grid needs for the winter weeks.

However, although this one here in the video has a higher efficiency - these hydrogen panels are on orders of magnitude cheaper to produce than ones using silicon; Which means it has the lowest cost per MWh. Also these panels produce hydrogen in their cells passively even when the sun is not out - although the production is higher when the sun is present.

So people are negating it in both directions, Chinese panels are better, and Oxford panels have a short life. Whereas at the moment it is actually exactly the other way around. They will not be manufactured in the UK, because the UK uniquely arranges itself to give advantage to playing with numbers on paper, and taxes manufacturing plants twice as much as in Germany and about four times as much as in China.

In tech it's not that 9 out of 10 technology "breakthroughs", e.g. your battery comments, will fail. It's the 1 in 10 technologies that make it and become a game changer. Keep the faith.

[@OG.551.98]

Thanks for sharing, where can I see an actual Spec sheet and it's Pascal wind resistance?

[@yp77738yp77739]

W/$ invested is the important measure. With panels as cheap as chips these are not a significant advantage unless you are very limited in installation area.

[@GreyDeathVaccine]

What about longevity of these new panels?

[@colinhudson7426]

The roof stays cooler if the panel is supplying power. If the sun's rays that are perpendicular to the panel have an intensity of 1000 watts per square metre and 240 watts are drawn off as electricity (24% efficiency), then the panel will be as hot as it would be if disconnected and receiving just 760 watts. First law of thermodynamics - conservation of energy. This is counter intuitive since, in general, devices that supply or supplied with an increased current get hotter !

1970: "Solar energy is free and is going to change the world forever..." 2024: "New solar panels will change the world forever. This is the breakthrough that we have been waiting for".

[@markfp9705]

Panel efficiency has increased by 50%? Where does that come from? We got solar panels fitted last year, I was shocked to find how little efficiency had increased since these things were released 15 years ago. We're in Scotland, energy produced in the winter is virtually nothing, which is a shame because its when we need it.

[@MichaelGammon21bravo]

where are the solid state graphene batteries?

[@charlesdonly776]

The issue is not mis-led or not.. the issue is the valley of death, which is the trough between 2 modes: the first is the proof of concept followed by a news release, but the technology is not ready for production or reliability or cost. The second distribution is scale. In between is the valley of death, and plenty of good technology dies in the valley. That is how it goes. It is not mis-led or personal…

[@igorpupkinable]

«Groundbreaking 24.5% efficiency». No, thank you. Please let me know when it gets to at least 50% - a real breakthrough. Happy for engineers to achieve even that.

[@aggiewoodie]

What’s the lamp in the corner behind the chair?

[@adamanthony7465]

Extraordinary. Wind is going the way of coal.

[@wallacegrommet9343]

Night says otherwise

[@bilgyno1]

Definitely not. There will be wind and solar in a nice mix with some battery storage. Then some other stuff to fill in the rest, such as hydro and nuclear. The mix will be different depending on the location of course.

[@T_157-40]

What is the web site of Oxford EV?

[@patclark2186]

When the company I work for puts solar panels on it's roof, I'll know its cost effective. Meantime I'll watch the technology improve.

[@ThePhilcam]

Twice the performance or half the price technology only gets better!

[@pleongv1]

I recall panel in Malaysia already hitting 26% efficiency

[@marccracchiolo4935]

27% is impressive it’s approaching the theoretical maximum of 30% this is a great application of AI I hope it lives up to the hype

[@marccracchiolo4935]

27% is impressive it’s approaching the theoretical maximum of 30%

[@q.e.d.9112]

Wikipedia doesn’t agree with you. They quote “As of 2024, the world record for solar cell efficiency is 47.6%, set in May 2022 by Fraunhofer ISE”

[@ahnilatedahnilated7703]

But the question once again about perovskite is, how long do the solar cells last? We all know perovskite has a low life span.

[@DileepaRanawake]

Glad you mentioned the insanity of an Oxford spin off manufacturing in Germany (and possibly US owned). We thank Margaret Thatcher for the collapse of British Manufacturing and then Cameron for the loss of access to the EU single market.

[@SigFigNewton]

Is it not better for the British consumer if the solar panels are produced where production will be less expensive? That’s the standard argument, isn’t it?

[@protagonist9716]

They need to be produced in China coz German panels will be more than 20% more expensive then Chinese thus negating cost brevity benefit ratio

[@Links-Plus2]

Are they hail proof?

[@UtubeRfarlefty]

Any news on recycling solar?

[@202AMERICA]

The ONLY knock on perovskite is "Operating Life / Duration" --- wonder what THAT is !

[@davidhollocher7924]

Progress does happen, but 70% of the time the hype falls well short of the actual results. I worked in high tech for decades. 20% of the new products made 80% of the new product revenue. So progress involves a lot of failures. The naysayers are usually right. Predicting which new innovations will succeed is a fools errand...

[@carusmike]

You've got it all wrong. I'm a nay-sayer. A nay-sayer to mass early adoption when the rate of progress is so dramatic. We're getting there. We will get there. Solar panels. Wind. Even fusion. Etc. I am happy to wait for the technology and the cost.

[@litestuffllc7249]

Presenting something as a breakthrough when it "claims" to increase solar panel efficiency from 20 to 25% is the sort of hype that end in dissapointment. What is the price of these panels? You can already buy solar panels with 40% efficiency; but they cost so much the are mostly used on satellites. If they cost isn't comparible; then the improved efficiency will mean nothing; higher efficiency must be met with equal or lower price to have any impact. Even if solar panels literally cost nothing; it sn't the panel costs that make the ROI low; it is the cost of installation and battery storage that makes them uneconomical in most locals with modest sun.

[@ianhaylock7409]

You know they won't be cheap because they're made in Germany. The country where all the manufacturing is currently closing down due to high energy costs.

[@timypp2894]

Not just Britain manufacturing is down the pan, it's also the EU is trying to emulate the US green incentive bill. Britain is hard up whilst the EU is giving green subsidy

[@JimmyDoyel-by2cp]

cool, but is it cheap? 😁

[@ChrisR-xs9wp]

For utility scale, it won't matter much. Most of the solar costs are for the land and connection costs. Higher efficiency makes better use of the land.

[@stephenbrickwood1602]

​@ChrisR-xs9wp rooftop is dirt cheap realestate 😊. Rooftop has no grid transmission costs, it is at the customer's building or home. Millions and millions of rooftop acreage. Free for the customer to install new PV panels. 👌 😊

[@Withnail1969]

The internet did work in the 1990s.

[@dylanthomas12321]

I remember. Text-based. And no Trolls!

[@keithjansen1734]

I am a scientist and when you say you did DAYS of research it means very little. Also these panels are 2% better than ones available now but the next ones will be 4% more efficient so why not wait? Lastly no cost factor was given,2% more energy for 20% more cost is hard to make financial sense of.

[@robcooper5813]

What about building a new roof from solar panels? Can you update what the latest is in this development? This will increase adoption.
