@mnomadvfx Now I gotta do more research? I'm so sick of the web and social media in particular. I used the Internet before the web, back in the 70s at a research university. It should've never been made available to the general public. They weren't ready. Still aren't.
Two or three generations ago, the Academy of Linguistics started adding technical words to Spanish. This breakthrough doesn't surprise me. After all, the saying goes, "Language structures the mind." The Viking described a trial-and-error process to get to 60+ % efficiency sounds like Thomas Edison describing his trial-and-error process for his light bulb.
I'll believe it when I see it coming off the end of a production line and being sold en mass. Because whoever does that will have a hit on their hands.
Efficiency is wonderful, but I think the thing that will boost solar the most is CHEAPNESS, ease of manufacture, eco-friendliness (meaning no toxic materials and byproducts), and ease of installation. What ever happened to the printable solar cells? Those seem like they were pretty great. They were cheap. They could be printed onto almost any material, including flexible fabric. It doesn't matter how efficient something is if it is 10 years away and made out of either toxic or expensive materials. And we need to really be working on energy storage, since that is the key to adding renewables to any energy system.
60% is almost certainly using concentrators, and it is stated that it is purely a lab achievement rather than a production ready technology. Previous concentrator based multi junction cells had managed >50% efficiencies.
An additional statement is, it is only applicable to red/yellow light. Given the lowest energy light is red, and the highest blue, for the external light spectrum, most of the energy would be lost as heat.
@electric Viking,, I don't think you are understanding this correctly. Gallium phosphide is most likely the bulk material and gallium is extremely expensive and hard to find and currently under Chinese control and they have greatly limited exports. Not a wise move to depend on gallium. Titanium is most likely just a surface film for optical properties. I think gallium comes out of aluminum smelting process if I recall correctly. This is going to be impractical probably even if they achieved much higher efficiency than polysilicon. First solar's Telerium is probably a better value when it gets its efficiency towards its theoretical maximum.
Titanium is $90 per kg. Gallium is $900 per kg. The price of silicon used in conventional solar cell is $9 per kg. These cells will be at least 10x more expensive, for a 1.6 x increase in energy yield. This technology will go nowhere, fast.
Eh? Perovskites are relatively chip as production requires much lower temperatures than silicon cells, and you only need a very thin layer of the material compared to silicon for the same conversion efficiency. The overall cell will be more expensive than pure silicon based cells as it is a tandem (multi junction) cell, but the additional cost will be nowhere near 10x even at the beginning, let alone once it has scaled.
And reliable, durable, consistent, etc. Yes, exactly. I'm all for solar getting better. But I'm all for reporting objective reality vs. endless hype for clicks.
its all about cost you can build compound semiconductor cells that achieve 80% and they have been around for years but they are extremely expensive to manufacture
The highest efficiency record for solar cells I have heard of was 48% (Scientific American) for 4 layer cells. I would be interested in your reference.
Perhaps they will hit the market in time for the Aptera II. (the stock footage of reflector array boilers seems a bit off topic, I recall an observation calling that technology no longer cost competitive)
Coal and gas are dying. As solar, wind, and storage prices drop, coal and gas will die faster. The renewable energy technology we have right now is good enough. Improvements make things better.
Assuming your numbers correct, then it would be 60% of 65% (avg) or about 39% efficient. Compared to "the most efficient varieties built using high-performance N-type monocrystalline cells, enabling panels to reach up to 24.3% efficiency" Moving from 24% to 39% would be a very major improvement. Let's hope it works out. At this point the major costs for solar are the frame, cover glass, and installation. A more efficient wafer taking us from 24% to 39% would generate far more power per dollar spent. But having followed renewable energy, EVs, and batteries for more than three decades I've learned not to get my hopes up.
@@slavko321 I've roofed a few houses, both shingles and steel panels. Robots can have that job. What I don't understand is why we don't have solar panel roofing. Not solar panels installed over roofs, but solar panels being the actual skin of the roof. I know at least one company is doing that, but it hasn't caught on.
This 60% efficient solar cell will remain in the lab, indefinitely as the materials and elements used to produce them, are EXTREMEY expensive. First Solar's modules are also gallium and cadmium, and are produced at roughly 3-times the price of silicon cells. Scientists confirmed 45%+ efficiencies in cells, in the lab, years ago, that have never come to market, for the same reason. Lab results and market worthy products, are very different animals.
While the materials are expensive, the amounts needed may not be deal-killers. And, since these materials are not "used up" but can most likely be recovered and reused then some of the initial cost may be recoverable.
No one would want to use cadmium in a solar cell : it is a toxic metal, and the flimsy construction of a solar panel would result in its release into the environment.
@@michaeledwards2251 You are correct. It would be a bad idea to use cadmium in solar cells. That's why CdTe, cadmium telluride in solar panels. CdTe is a very stable and non-harmful compound. "The only pathways by which people might be exposed to PV compounds from a finished module are by accidentally ingesting flakes or dust particles, or inhaling dust and fumes. The thin CdTe/CdS layers are stable and solid, and are encapsulated between thick layers of glass or plastic. Unless the module is ground to a fine dust, dust particles cannot be generated. The vapor pressure of CdTe at ambient conditions is zero. Therefore, it is impossible for any vapors or dust to be generated when using PV modules. You don't want to be eating sodium or drinking chloride. But putting table salt, NaCl, on your food is fine.
Achieving 60% energy conversion is one thing. But to make it work on a commercial scale is quite something else. Mind you, if it does work, they need to install it in the southwestern quadrant of the continental USA and the Australian Outback to really capture electric power from solar power on a truly massive sacle.
5:51 theoretically lol, Its like theoretically I can be the champion of 100m, gymnastics and shortput at the same time. Yes, its theoretically possible as I am a functional human being just like other olympians. 😂
Mate you need to start putting your sources in the description. if it’s not acceptable for a high school assignment to leave out references, it’s not acceptable here.
I have heard quantum dot solar could reach as high as 66% in the future. Right now it is quite low and increasing fast. These numbers are challenging to believe, but the last thing I want to do is say its impossible.
Even after reading the article, I'm not completely sure if their 60% conversion limit is of the suns total energy, or just 60% in the 550nm wavelength and above. Which would mean the overall efficiency will be lower.
Guess it depends on the Panel prices if they are also 2/3x current prices but hopefully change!

They only last minutes to a few hours under lab conditions so don't get too excited.. A fairly stable cell in the high 30's can last close to a year but one that can last several decades and be in mass production is still a decade away.. Layering and enhancing the cells with a substance that readily releases electrons with minimal excitation from sunlight like a nuclear element also produce lots of electric but they degrade at an atomic level and have no longevity..
Article title in PV Magazine: "First attempt to build solar cells based on gallium phosphide, titanium" Quote: _«“Research on these cells has been going on for over 15 years in our group,” the research's lead author, Javier Olea Ariza, told pv magazine. “We published the first article in the series in 2009 and, in our latest article, we have moved on to making the first real devices. The devices do not work well yet and their current efficiency is very poor. Although more work is needed, these cells have the theoretical potential could reach efficiencies of around 60%.”»_
A lot of different achievements are being talked about solar panels and batteries. Much of those remain in research laboratories only. My approach is "WHEN WE SEE IT, WE SEE IT." Until then it is NOTHING for a common man.
Correct. It's fun to see new ideas appear, but many "breakthroughs" never make it in the real world. There's a huge danger in getting excited about what might come to market and using that as an excuse to not move faster with what we have in hand. We are getting our butts kicked by climate change. We would be stupid to let it get stronger than need be by not working diligently to limit the extreme.
This is all fine for the continent called Australia . Sam you should look over the insolation maps for the world. It will illustrate the energy available problems for the United States and Canada.
@@Leo555ZZZ Viking(and his mate Albo) said solar panels work at night.Still waiting for how much power he has produced(night time), he never tells us..
more EV... i mean PV porn from Sam! LOVE IT! keep it coming! even _if_ 95% is just hype... just 5% of REAL POSSIBILITIES in future solar Photo Voltaic panels or batteries -whether doped lithium, silicone, solid state, or whatever - that truly would be PHENOMENAL, anyone who DIDN'T put solar panels on their roof would be a burning-money fool
3:21 small slip up: you said the efficiency limit of silicon is 33%, and that means it cant use 77% of the sun enegry, while actually it would be 67%. 33% plus 77% would be 110%
Yeah, the mistake is in the article. It says 33.7% efficiency limit means you can't use 77.3% of the suns energy, so their math adds up to 111% somehow. Doesn't give me a lot of confidence in the accuracy of the article.
Someday we'll be able to generate power from the energy of the full electromagnetic spectrum, not just limited bands of visible light. #SwitchToSolar #SwitchToElectric #OneEarth #EndFossilFuels
China has the world’s largest reserves of titanium. China produces the most titanium and China’s consumers consume the most titanium In 1985 as part of Lockheed’s test flight team, we saw a Chinese cargo plane with a cargo deck made from titanium. The reactions would have been similar if the streets were paved with gold
"Titanium is mined in Australia, Sierra Leone, South Africa, Russia and Japan." "These minerals (including titanium) are primarily sourced from beach sands in Australia, South Africa, and India, as well as from hard rock deposits in Canada, Norway, and Ukraine." People often confuse "reserves" and "occurrence". China may have the largest reserves, the largest amount on hand and/or the highest ability to refine titanium. That's been true of other important materials such as lithium. China, due to low cost labor and a lack of environmental regulations, took over the production of many materials and products. The US, for example, used to extract and refine lithium in North Carolina but those operations shut down due to China undercutting with lower prices. The US has vast deposits of lithium. The US has a high occurrence of lithium.
Passive design is high efficiency, but the building industry moves slowly. e.g. Using glass tiles on a roof, if you're not careful will get growing moss lifting them off.
55 seconds in shows solar panels installed on a dark colored roof . Installing solar panels on a dark roof in a no no. Solar panels installed on a dark colored roof will produce less power than panels on a white or silver roof. The enemy of solar panels are heat. Black or dark colored roofs produce heat that lowers the amount of electricity produced. Painting roofs white before installing solar panels called “cool roofing,” is an expanding business in the US. Australia should be doing the same. Some states in the US have building code by laws that require that industrial buildings must have white roofs. For example: California has stringent cool roof requirements under its Building Energy Efficiency Standards. These regulations often require roofs to meet minimum solar reflectance and thermal emittance values, which can be achieved with white or other light-colored roofing materials. New York City mandates cool roofs for certain buildings under its building codes. Phoenix, Arizona and Los Angeles, California also have specific cool roof regulations.
Avg Solar efficiency for purchase 1970:6% 1990:12.5% 2010:20% 2024:24.1% 2030: 27% 34.1% wouldn’t be reached til 2050 at this rate, hopefully it’s the beginning of exponential S curve advances similar to silicon chips and computer memory. How are you all scoffing at this story & our massive improvements to solar. ICE went from 10-20% efficiency in 100 years. A propane generator is atleast 30% efficient.
Pervskite captures a different frequency range than polysilicon. Has stability issues (lifespan), hard to layer on the Silicon, inputs have other uses and Lead in the mix is considered a risk factor!
Gas and coal is already doomed with the current solar panel efficiency. Solar electricity is 1/8 the price of coal and and 1/6 th cost of natural gas. And, the price of solar is going down while the price of coal and gas are going up. As people realize the enormous negative health impacts of fossil fuels the momentum will grow.
Sam: you have a great channel but your understanding of physics is limited. Laws of physics don’t allow a conversion of photons to electrons at 60 percent. Conversion of one form of energy to another form always leads to losses governed by the laws of thermodynamics
Sorry :) Orm Stórolfsson ;) I'm tired of getting caught up in brand-new tech that is beyond my lifetime before it hits the market. I. like most people, want to see what we can install NOW!! Matt Ferrel, and many others do the same, tantalises us, then tells us that is going to be available to the public in 15 to 20 years!!!!!!!!!!!!!!!!!!!!
Over rated. Existing solar panels are essentially free... the cost is with installation and regulation (grid connection primarily). Transmission network capacity is the next bottleneck. Maybe a doubled capacity solar panel will help incrementally as first generation panels are replaced a decade into the future.
Reduce or eliminate your connection. Storage. Micro grid. They are stealing from you. Too much energy generated in day time. This kills the market. Zero cost value at peek time
Cook your roof with solar panels. Raise the price of homeowners' insurance. Maintenace cost to eat away any gain. Predatory financing. And when you have figured out solar is a rip off it's too late. Damage to roof and little to no resale on any of it. Government assistance is evaporating quickly. 60% better??? from 180% loss to 120% if that. Once it's attached to your roof and you pay the bill, you will forever complain and cry you did the thing!
IDK, if I put those on my house and garage, I would not know what to do with it all. Oh wait, it will be my great grand kids that would actually realize this, MAYBE. Never mind.
Brother, it's not the generation through solar that's the problem. It's the storage and on demand nature of that generation. If you have extended cloudy weather, then you have problems. Today batteries can only provide cities with a couple of hours of power, factories such as smelters we are talking minutes. We need on demand power 24/7 for reliability and most importantly affordability. As you know Sam, here is Oz we are being smacked by power prices. Where in reality, we should have the cheapest prices on earth. Ideology by Chris Bowen the energy minister clown has destroyed business and plunged families into poverty. It's a joke.
You can find solar cells that already get 40% which are used on satellites; but they are super costly. You made no mention of cost. Your understanding of the contribution of solar at present is wrong. Solar only produces 2% of world energy production; thus if magically you could replace all cells with ones 3x more effective it would only come to 6% of world production and of course cells are not the big expense - installation and batteries are the main high cost component of Solar power. If you can ever get some cheap efficient cells and cheap storage; maybe it would be worth investing in; at present and the last 20 years Solar has been a failure.

It is 60% but only at wavelengths >550nm, and approximately 60% to 70% of the total solar energy reaching Earth has wavelengths greater than 550 nm
Assuming your numbers correct, then it would be 60% of 65% (avg) or about 39% efficient. Compared to "the most efficient varieties built using high-performance N-type monocrystalline cells, enabling panels to reach up to 24.3% efficiency"
Moving from 24% to 39% would be a very major improvement. Let's hope it works out. At this point the major costs for solar are the frame, cover glass, and installation. A more efficient wafer taking us from 24% to 39% would generate far more power per dollar spent.
But having followed renewable energy, EVs, and batteries for more than three decades I've learned not to get my hopes up.
@@bobwallace9753 you know what that means... roofing robots!
@@slavko321
I've roofed a few houses, both shingles and steel panels. Robots can have that job.
What I don't understand is why we don't have solar panel roofing. Not solar panels installed over roofs, but solar panels being the actual skin of the roof. I know at least one company is doing that, but it hasn't caught on.
This 60% efficient solar cell will remain in the lab, indefinitely as the materials and elements used to produce them, are EXTREMEY expensive. First Solar's modules are also gallium and cadmium, and are produced at roughly 3-times the price of silicon cells. Scientists confirmed 45%+ efficiencies in cells, in the lab, years ago, that have never come to market, for the same reason. Lab results and market worthy products, are very different animals.
Thank you for the context. I was going to pass this off as BS but maybe it’s only BS for mass production.
While the materials are expensive, the amounts needed may not be deal-killers. And, since these materials are not "used up" but can most likely be recovered and reused then some of the initial cost may be recoverable.
No one would want to use cadmium in a solar cell : it is a toxic metal, and the flimsy construction of a solar panel would result in its release into the environment.
@@michaeledwards2251
You are correct. It would be a bad idea to use cadmium in solar cells. That's why CdTe, cadmium telluride in solar panels. CdTe is a very stable and non-harmful compound.
"The only pathways by which people might be exposed to PV compounds from a finished module are by accidentally ingesting flakes or dust particles, or inhaling dust and fumes. The thin CdTe/CdS layers are stable and solid, and are encapsulated between thick layers of glass or plastic. Unless the module is ground to a fine dust, dust particles cannot be generated. The vapor pressure of CdTe at ambient conditions is zero. Therefore, it is impossible for any vapors or dust to be generated when using PV modules.
You don't want to be eating sodium or drinking chloride. But putting table salt, NaCl, on your food is fine.
Not 60% efficient, it's 60% MORE efficient than the previous record holder.
Achieving 60% energy conversion is one thing. But to make it work on a commercial scale is quite something else. Mind you, if it does work, they need to install it in the southwestern quadrant of the continental USA and the Australian Outback to really capture electric power from solar power on a truly massive sacle.
5:51 theoretically lol, Its like theoretically I can be the champion of 100m, gymnastics and shortput at the same time. Yes, its theoretically possible as I am a functional human being just like other olympians. 😂
Mate you need to start putting your sources in the description. if it’s not acceptable for a high school assignment to leave out references, it’s not acceptable here.
This one is in the description, near the end. The one from the interesting engineering website.
yeah I think the average is more like around 20 % for most of the best installed stuff. yeah those are expensive materials.
Tbh it was a bit hard to wait until 1:45 to finally get confirmation, that it will be a game changer.
Pass the salt, please.
I have heard quantum dot solar could reach as high as 66% in the future. Right now it is quite low and increasing fast. These numbers are challenging to believe, but the last thing I want to do is say its impossible.
Where high efficiency solar cells could really be game changing is on the roof of a RV or a solar powered house boat.
Even after reading the article, I'm not completely sure if their 60% conversion limit is of the suns total energy, or just 60% in the 550nm wavelength and above. Which would mean the overall efficiency will be lower.
Well I'm happy with my off grid system, but I may have to upgrade in a couple years if things keep improving.
Guess it depends on the Panel prices if they are also 2/3x current prices but hopefully change!
They only last minutes to a few hours under lab conditions so don't get too excited.. A fairly stable cell in the high 30's can last close to a year but one that can last several decades and be in mass production is still a decade away.. Layering and enhancing the cells with a substance that readily releases electrons with minimal excitation from sunlight like a nuclear element also produce lots of electric but they degrade at an atomic level and have no longevity..
Article title in PV Magazine: "First attempt to build solar cells based on gallium phosphide, titanium"
Quote: _«“Research on these cells has been going on for over 15 years in our group,” the research's lead author, Javier Olea Ariza, told pv magazine. “We published the first article in the series in 2009 and, in our latest article, we have moved on to making the first real devices. The devices do not work well yet and their current efficiency is very poor. Although more work is needed, these cells have the theoretical potential could reach efficiencies of around 60%.”»_
Given them 10 years and 60% may be achieved : ideal for islands, space use, and super efficient EVs.
A lot of different achievements are being talked about solar panels and batteries.
Much of those remain in research laboratories only.
My approach is "WHEN WE SEE IT, WE SEE IT." Until then it is NOTHING for a common man.
Correct. It's fun to see new ideas appear, but many "breakthroughs" never make it in the real world. There's a huge danger in getting excited about what might come to market and using that as an excuse to not move faster with what we have in hand. We are getting our butts kicked by climate change. We would be stupid to let it get stronger than need be by not working diligently to limit the extreme.
At 4:36, "the theoretical potential ...is therefore 60%". No one has got anywhere near that yet and is unlikely to ever.
Substitute silver for gold. There's already a lot of silver used in PV panels
This is all fine for the continent called Australia . Sam you should look over the insolation maps for the world. It will illustrate the energy available problems for the United States and Canada.
Not even fine for Australia ,,,,night time and cloud guarantees it.
@@Leo555ZZZ Viking(and his mate Albo) said solar panels work at night.Still waiting for how much power he has produced(night time), he never tells us..
more EV... i mean PV porn from Sam!
LOVE IT! keep it coming! even _if_ 95% is just hype...
just 5% of REAL POSSIBILITIES in future solar Photo Voltaic panels or batteries -whether doped lithium, silicone, solid state, or whatever -
that truly would be PHENOMENAL, anyone who DIDN'T put solar panels on their roof would be a burning-money fool
3:21 small slip up: you said the efficiency limit of silicon is 33%, and that means it cant use 77% of the sun enegry, while actually it would be 67%.
33% plus 77% would be 110%
Yeah, the mistake is in the article. It says 33.7% efficiency limit means you can't use 77.3% of the suns energy, so their math adds up to 111% somehow. Doesn't give me a lot of confidence in the accuracy of the article.
NiCe 👍
Appreciate it!
👍👍
60 pissent conversion!
Sam, what’s your system size?
To much good news is usually a dream
Dont perovskite cells give you about 60% efficiency?
Someday we'll be able to generate power from the energy of the full electromagnetic spectrum, not just limited bands of visible light.

A Piped Dream
China has the world’s largest reserves of titanium. China produces the most titanium and China’s consumers consume the most titanium
In 1985 as part of Lockheed’s test flight team, we saw a Chinese cargo plane with a cargo deck made from titanium. The reactions would have been similar if the streets were paved with gold
"Titanium is mined in Australia, Sierra Leone, South Africa, Russia and Japan."
"These minerals (including titanium) are primarily sourced from beach sands in Australia, South Africa, and India, as well as from hard rock deposits in Canada, Norway, and Ukraine."
People often confuse "reserves" and "occurrence". China may have the largest reserves, the largest amount on hand and/or the highest ability to refine titanium. That's been true of other important materials such as lithium. China, due to low cost labor and a lack of environmental regulations, took over the production of many materials and products. The US, for example, used to extract and refine lithium in North Carolina but those operations shut down due to China undercutting with lower prices. The US has vast deposits of lithium. The US has a high occurrence of lithium.
Thermal solar is 80 percent. And is in use today.
Concentrating and Parabolic solar are problematic. The big players returning to PV. China is making them so cheaply
Passive design is high efficiency, but the building industry moves slowly. e.g. Using glass tiles on a roof, if you're not careful will get growing moss lifting them off.
lol the more green we go the more fossil fuel we need! Drill baby drill! Poke holes everywhere!
Nice, but you're showing pictures of mirrors
Don’t waste money on solar now; when this new technology comes out, it will be cheaper and better.
Mobile applications should use these first where square footage is limited.
And by sheer coincidence, it gets wetter and cloudier. **cough ***cough cough seeding
55 seconds in shows solar panels installed on a dark colored roof . Installing solar panels on a dark roof in a no no. Solar panels installed on a dark colored roof will produce less power than panels on a white or silver roof. The enemy of solar panels are heat. Black or dark colored roofs produce heat that lowers the amount of electricity produced. Painting roofs white before installing solar panels called “cool roofing,” is an expanding business in the US.
Australia should be doing the same. Some states in the US have building code by laws that require that industrial buildings must have white roofs. For example: California has stringent cool roof requirements under its Building Energy Efficiency Standards. These regulations often require roofs to meet minimum solar reflectance and thermal emittance values, which can be achieved with white or other light-colored roofing materials.
New York City mandates cool roofs for certain buildings under its building codes.
Phoenix, Arizona and Los Angeles, California also have specific cool roof regulations.
Black whirley birds as well. Oh dear.

Avg Solar efficiency for purchase
1970:6%
1990:12.5%
2010:20%
2024:24.1%
2030: 27%
34.1% wouldn’t be reached til 2050 at this rate, hopefully it’s the beginning of exponential S curve advances similar to silicon chips and computer memory.
How are you all scoffing at this story & our massive improvements to solar. ICE went from 10-20% efficiency in 100 years. A propane generator is atleast 30% efficient.
Pervskite captures a different frequency range than polysilicon. Has stability issues (lifespan), hard to layer on the Silicon, inputs have other uses and Lead in the mix is considered a risk factor!
link?
Great news. It's only getting better. ... the end is near. Hahaha , or the beginning
Gas and coal is already doomed with the current solar panel efficiency. Solar electricity is 1/8 the price of coal and and 1/6 th cost of natural gas. And, the price of solar is going down while the price of coal and gas are going up. As people realize the enormous negative health impacts of fossil fuels the momentum will grow.
Gas and coal are dead? Do those new solar cell work at night?
Sam: you have a great channel but your understanding of physics is limited. Laws of physics don’t allow a conversion of photons to electrons at 60 percent. Conversion of one form of energy to another form always leads to losses governed by the laws of thermodynamics
Don't clikbait is only 34%
35% is already too much..
40% is impossible..or too Costly..
60% is limited by Carnot's Cycle..
Except for Thermal Combined Cycle..62%
Solar sucks for homes…Solar farms with Nat. Gas backup and night production if the way forward…
Don't tell Elon.... unless you want more of his projects.
Ah… already thursday bullsh1t’0 clock…
Solar is dodgy because weather
Wanna bet once we finally invent decent solar panels, the climate change will result to 24 hour cloud cover.
Solar cells are not that hard to make they shouldn't cost more than a TV but they do.
Sorry :) Orm Stórolfsson ;) I'm tired of getting caught up in brand-new tech that is beyond my lifetime before it hits the market. I. like most people, want to see what we can install NOW!! Matt Ferrel, and many others do the same, tantalises us, then tells us that is going to be available to the public in 15 to 20 years!!!!!!!!!!!!!!!!!!!!
What's the catch: made of platinum, mercury and cadmium? 60% in bright sunlight only, cloudy 2.3% efficient? lasts 3-4 years?
Over rated. Existing solar panels are essentially free... the cost is with installation and regulation (grid connection primarily). Transmission network capacity is the next bottleneck. Maybe a doubled capacity solar panel will help incrementally as first generation panels are replaced a decade into the future.
Reduce or eliminate your connection. Storage. Micro grid. They are stealing from you. Too much energy generated in day time. This kills the market. Zero cost value at peek time
Storage is the key. Reduce your cost to zero
There is not enough titanium. What there is? Is Russian.
Cook your roof with solar panels. Raise the price of homeowners' insurance. Maintenace cost to eat away any gain. Predatory financing. And when you have figured out solar is a rip off it's too late.
Damage to roof and little to no resale on any of it. Government assistance is evaporating quickly. 60% better??? from 180% loss to 120% if that. Once it's attached to your roof and you pay the bill, you will forever complain and cry you did the thing!
IDK, if I put those on my house and garage, I would not know what to do with it all. Oh wait, it will be my great grand kids that would actually realize this, MAYBE. Never mind.
Brother, it's not the generation through solar that's the problem. It's the storage and on demand nature of that generation. If you have extended cloudy weather, then you have problems. Today batteries can only provide cities with a couple of hours of power, factories such as smelters we are talking minutes. We need on demand power 24/7 for reliability and most importantly affordability. As you know Sam, here is Oz we are being smacked by power prices. Where in reality, we should have the cheapest prices on earth. Ideology by Chris Bowen the energy minister clown has destroyed business and plunged families into poverty. It's a joke.
We know...
You can find solar cells that already get 40% which are used on satellites; but they are super costly. You made no mention of cost. Your understanding of the contribution of solar at present is wrong. Solar only produces 2% of world energy production; thus if magically you could replace all cells with ones 3x more effective it would only come to 6% of world production and of course cells are not the big expense - installation and batteries are the main high cost component of Solar power. If you can ever get some cheap efficient cells and cheap storage; maybe it would be worth investing in; at present and the last 20 years Solar has been a failure.
Mr. Viking... I've been in the EV and renewable energy industries for 25+ years. To me you have been on the ragged edge between legitimate reporting and clickbait misrepresentation. You are gonna have to do better or I will choose to unsubscribe. This definitely qualifies as clickbait misrepresentation.
