Dawn of Solar Age Declared as PV Beats All Other Forms of Power (bloomberg.com)
Solar power blossomed faster than for any other fuel for the first time in 2016, the International Energy Agency said in a report suggesting the technology will dominate renewables in the years ahead. From a report: The institution established after the first major oil crisis in 1973 said 165 gigawatts of renewables were completed last year, which was two-thirds of the net expansion in electricity supply. Solar grew by 50 percent, with almost half new plants built in China. "What we are witnessing is the birth of a new era in solar PV," Fatih Birol, executive director of the IEA, said in a statement accompanying the report published on Wednesday in Paris. "We expect that solar PV capacity growth will be higher than any other renewable technology through 2022." This marks the sixth consecutive year that clean energy has set records for installations. Mass manufacturing and a switch by governments away from fixed payments for renewables forced down the cost of wind and solar technology. The IEA expects about 1,000 gigawatts of renewables will be installed in the next five years, a milestone that coal only accomplished after 80 years. That quantity of electricity surpasses what's consumed in China, India and Germany combined.

Photovoltaics (PV) is a term which covers the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. A typical photovoltaic system employs solar panels, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop mounted or wall mounted. The mount may be fixed, or use a solar tracker to follow the sun across the sky.

Maybe it will kick-start companies to do more battery research. Better batteries will fundamentally change a lot of items, especially transportation. Get a battery to 1/10 the energy density per volume as gasoline, and you won't need internal combustion engines anymore. Get battery tech cheaper, and Tesla Powerwall like whole-house UPS systems become common, which can allow battery banks to charge when it is cheapest, as well as provide a couple hours of power if the grid drops.
That's already figured into the cost. Still comes out ahead. And once we start using photovoltaic energy to make photovoltaics, we take fossil fuels out of the picture entirely.

yeah, after 25 years it "only" has 80% of its initial rated max output. Which means you can use them for 50 years easily.
I have seen a few reports that they are lasting quite a bit longer than expected and still performing, in some cases 10 years past their estimated 20 year functional lifespan. If we have to make a lined pit in the ground and throw them all in it every 30 years, that will be fine.
They have no moving parts (unless you use trackers) and they take advantage of "free" energy that will be here as long as the earth is habitable. It is inevitable that they will take over energy production.

In 25 years solar "panels" will be as cheap and flexible as plastic sheeting. Energy will be nearly free and we'll be struggling with who should be allowed to have children and deciding which grossly overpopulated areas need to "purged".
Gosh, if only Solar arrays were like coal, gas, and nuclear plants that require absolutely no maintenance, part replacement or waste disposal.
Oh wait.
Seriously, in 20 years, they can expand their system to cover increased demand, and if these cells fail, they can recycle the valuable metals and purchase new ones. You might as well be complaining that the sun could go out, or that the cleaner air they breathe lets them go outside so much they get skin cancer.
Falling off is not the same thing as not working at all. In some installations, where you have space restrictions and power requirements; this will matter. In other locations (rural/solar farms?) where space is less critical; it won't matter so much. Why get rid of the old panels when you can add a single (newer/cheaper) panel and end up with more total capacity then before? Even users with space restrictions are likely to be able to sell their reduced output panels to someone who doesn't have that restriction. There are airplanes built in the 60s still being used commercially because people still get value out of them. While I doubt that panels will remain viable after 60 years, they might do 30 or 40. The last user might have even bought them at the cost of shipping/handling just so the previous owner didn't have to dispose of toxic materials. Eventually, it will be time to scrap them; but that may well be far removed from the original purchaser and we will have plenty of time to make that as easy as getting rid of used motor oil.
The largely overpopulated areas will be the same like today: ... feel free to add your selection.

Population growth on the planet will probbaly stop in 30 - 50 years, so no worries there.
Energy will never be free. The production might be close to free, perhaps you pay 1cent per kWh, however transport, gridstability, balancing power, reserve power, and simple things as metering snd billing: will always have significant costs.
So when we are close to free energy, the prices will drop by half, but not go doown to 1cent or less.

No they are not projected to last 50 years at full or even majority output.

You are welcome on my lawn.
Personal anecdote, but I have a former neighbor who still has PV panels up that he threw in his backyard back in the 1980s, and they are still running at their rated wattage, if not a little bit above it.
The nice thing about solar panels is the fact that once set up, assuming no active tracking system, you don't have to do much upkeep. No moving parts, everything is solid state, and if one has an on-grid system, there are no batteries to have to keep watered or replaced.
I really can't think of anything wrong with solar, other than the obvious... it only works a part of the day.
I've had solar panels for two years now. I pay nothing in the spring, summer and fall months for electricity and far less in the winter than I ever did in the past. There no moving parts. The panels have a 25-year life span. The only thing left for me to do is buy a lithium-ion rechargeable battery for my home so I can have power when the sun goes down or it's really, really cloudy. It's kind of a no-brainer.
Is is it true that it still takes more energy to fab the silicon, make the frames, and deploy the panels than they ever get back in their operational lifetime?
Although I'm sure Exxon would like that misinformation to stay popular, that question was put to rest long ago, both in terms of the panels themselves and the PV industry as a whole. And that's reaching back to pay for panel development when production was inefficient.

Nothing. A well-made solar panel will last 40 years (there are some 40 year old solar panels still operating fine) and will probably last over 70 years: https://us.sunpower.com/sites/...
And nuclear plants have absolutely no expense involved in maintenance or refurbishment.
Most people have purchased solar through power purchase agreements that are typically 15 to 20 years long. At the end of that time, they can either buy the cheaper solar panels themselves or resign another PPL. Typically, the solar provider charges a set price -- today $500 -- to remove old panels. So, no. Consumers won't get sticker shock in 20 years. In fact, solar panels are becoming more efficient, so in 20 years, you'll need fewer panels to produce the same energy and they'll be cheaper to manufacture.
So assuming the non-renewable expansions averaged a 50% capacity factor, we get:
Actually wind and solar are over 5% of average power supply now and growing exponentially, with large double digit year-on-year percentages. And wind is already well over 10% of power in Europe.
-WolfWithoutAClause
"Gravity is only a theory, not a fact!"Is is it true that it still takes more energy to fab the silicon, make the frames, and deploy the panels than they ever get back in their operational lifetime?
It's called embedded (or embodied) energy. It's not true, unless there's an incredibly inefficient production/distribution method being used somewhere. Even if it were true, it would still make sense to produce them using other renewable energy types (i.e. hydro, geothermal) and use them where they were replacing non-renewables (though still not ideal).
Silicon is a *metal*. Sand is a silicate.
https://en.wikipedia.org/wiki/Silicon
There's an OSHA limit for silicon particle exposure at the end of the article but it doesn't seem particularly toxic.
The manufacturing process for panels reportedly uses chemicals that are quite toxic, however.
Sorry, are you referring to solar or current power plants? Because everything you said can apply to either.
As a society, we already see drops in performance when parts aren't replaced or maintained. We already deal with sticker shock when we need to repair or replace everything from turbine blades to scrubbers to pistons that can fail for any number of different mechanical or chemical reasons. We already have to dispose of filters and other parts that are contaminated with toxic materials. None of this is new.
What is new, however, are the rapidly falling prices for solar installs, zero emissions during operation, less frequent maintenance, and the fact that it's looking like 15-20 years may have been a conservative estimate, since we're already seeing them lasting far longer than originally expected. Which isn't to say that they solve all of our problems, nor that they come with no new ones, but suggesting that we shouldn't use solar until we deal with the issues you listed—issues which we already face—is like saying that we shouldn't allow a drug that cures 50% of patients suffering from an otherwise terminal disease, because it doesn't save 100% of them.
"When the performance of these things starts to drop off ..." ...their new lights, gadgets and appliances will need much less power, so the surplus to be sold is even higher.
Or you just do it like with a heating system, car, roof ...you replace it.
'I winter in Germany, solar output is almost non-existant.'
Get a brush until climate change takes care of the snow.
"Do solar panels work in the winter?
A common myth is that solar panels do not work during winter, but in contrary, the cold temperature will typically improve solar panel output. The white snow can also reflect light and help improve PV performance. Winter will only hurt solar production if the panels are covered with snow."
http://news.energysage.com/sol...
I would present the same starter question to you: Are you fucking serious? .5 * energy hitting those square feet of your roof during winter > 0 * energy hitting those square feet of your roof during winter.
Oh no, it's not perfect. Well, better that we do nothing at all and continue burning oil and coal until the perfect solution based on unicorn gall bladders is announced!

Honestly, I don't understand photovoltaic installations. Parabolic dish collectors with a sterling engine were like 34% efficient and what in the hell is this?!
You can get higher efficiency off thermal because you can get 100% of the light (you know, thermal) as energy. The most-efficient sterling engine ever built hit 38.5% thermal efficiency or 77% of carnot. At 73% efficient light redirection, you're looking at over 28% total thermal efficiency.
The only way you're beating a 73% efficient reflector feeding a 38.5% efficient sterling-driven generator is to make transparent solar cells capturing different bands. Current cells are doped with split-band crystals which excite in multiple bands; if you absorb those bands and transmit the unabsorbed bands, you can use a different material for the next layer down, which absorbs one of the transmitted bands. In other words: capture 19% of the thermal energy as electricity in the first layer, and 15% of the thermal energy (18.5% of what was transmitted) in the second layer. 34%.
Such a cell would be enormously-difficult to construct and have high costs. Maybe next decade.

Looks like both charts project majority output in 50 years.
100%-(.05%*50)=75%
or 100%-(20%*2)=60%
Your point is stronger if you use words like "dramatic reduction" or "just over half of the output remaining" or you don't link to things that contradict what you say as support.
Wow, sent an e-mail as suggested when clicking on "use classic" banner, and got a fast response that addressed my msg
Won't cheap panels combined with better/cheaper battery storage lead to a trend of just breaking grid ties and running standalone?
I think it's already somewhat practical now if you're willing to accept some limits on max current output, especially at night.
Western population growth already has stopped long long ago.
Nothing to fix if you have no clue at all.

The two references you provide indicate that a reasonable , even conservative estimate is about 0.5% degradation per year. After 50 years that leaves 78% of initial output. Pretty good I'd say!

Depends where you life.
In europe household battery storages are more and more connected into so called 'virtual power plants'.
They are used for balancing power snd reserve power.
That earns the owners money.
Going disconnected would make them lose that money.
In other words in the center of a city it makes no sense to go disconnected.
In a hut in a forrest up the mountains, perhaps it does.

I'm always amused that engineers miss the giant fusion reactor in the sky.
I'm still waiting for quantum tunneling junctions. These are solid-state devices which are currently researcher voodoo: you can make one, but most of its surface is useless. Boeng has confirmed they work, just that you make one the size of a quarter and you get a few square micrometers of useful area.
A quantum tunneling junction has something like 55% carnot efficiency for any given temperature drop at any absolute temperature which doesn't physically damage the material. It's similar to a peltier junction, which has 8% efficiency. Essentially, a peltier junction has electrons shifting more or less easily across a junction when a voltage potential is applied, which may cause them to release or absorb heat. A quantum tunneling junction has electrons crossing a dielectric when a voltage potential exists across two plates; the electrons have higher probability of crossing if they have higher energy, so "hot" electrons (absorb photons, i.e. thermal energy) move more-frequently, cooling one side and heating the other.
Cute. What can we do with it?
Ever filled a scuba tank?
When you compress a gas, it releases heat. release the gas elsewhere and it absorbs heat (gets cold). In fact, if you chill the tank enough and open it, you won't get any pressure: you freeze N2 into liquid N2 and now the N2 doesn't contain enough energy to produce force, thus pressure. Boiling is just molecules moving so forcefully they shove fluid out of the way and escape the vessel (buoyancy in a boiling liquid only occurs because the molecules in the bubble have enough energy to push the liquid away, making a low-density region that happens to be in the gas phase; add gravity and the low-density region is pushed to the surface by the heavy liquid).
So set up two compression chambers. Feed from a pump run off an engine; power the engine off this chamber. Use electricity from a battery (charged from an alternator off the engine) to run a quantum tunneling junction and pull heat emitted and from the atmosphere into the compressed air vessel.
Engineers like to point out here that you can't run a heat engine off a heat pump that shares its reservoir. They're talking about the atmosphere being the heat reservoir.
It's not an ideal reservoir.
You're emitting cold air into the atmosphere: the engine expands the air, which absorbs heat and spits out expanded (cooled) air. That air exits at a lower temperature than the air being pulled into the compression vessel, as well as the air from which the quantum tunneling junction is driving heat into the vessel. You're not injecting the cold output (engine exhaust) into the reservoir from which the heat pump (QTJ) is drawing--that is: the temperature of the exhaust isn't averaged with the atmosphere at point of contact with the heat pump.
Second, the atmosphere is heated by the sun.
Not only is the atmosphere big and capable of absorbing a huge amount of cold exhaust before your heat-engine-slash-heat-pump consumes the energy in its shared vessel and finally runs dry, but it's being fed energy from an external power source.
That external energy prevents the atmosphere from averaging its temperature out (in which case, it would already be at a temperature by which you can't run this machine). The heat from the sun is changing the entropy in the atmosphere, essentially playing the part of Maxwell's Demon--a thought experiment about exactly what I describe, with the mistake of not accounting for the work that the little cretin sitting on the gate expended to sort out hot particles from cold particles. The "demon" is being fed from the sun.
I've described nothing more than a Rube Goldberg machine that achieves solar power generation.
Whether you can build one is another matter; but the theory isn't totally-unsound, at least not for the reasons most engineers immediately cite.

Oh, it's grimmer than that. The father was first put in jail as a young man. Gaining a felony record and never having a chance at a regular life.
Meanwhile, the white kid wasn't even stopped, and if he had been stopped, would not have been searched, have been let off with a warning, or if he had actually have been arrested would have been given a deferred sentence (because he had a bright future), and finally if he had actually been sentenced- it would have been 50% to 90% lighter than the sentence given to the black youth for the same crime.
And yes- everything I just wrote has happened to black and white kids over the last 5 years. It's STILL happening. We need equal justice. If the laws fell as harshly on white families (especially rich white families) then the laws would be changed to be less harsh.
Within the last decade, while minority mothers are going to jail for 11 years for less than a joint- willie nelson was paying a $4,000 fine and being let off for a damn bag of pot.
And it's the same story all over the country.

Actually you could not even reach it as most of the road to the ferry was a dam: closed for cars because of fear of damage to the dam.
Now we rarely have a high water, because there is not enough snow in the mountains to cause it in spring.
The days with highest *percentage* of solar contribution are actually winter holidays with clear skies, like 1st of January. Of course the reason is: it is a holiday, peak demand is only 60% of a work day. But it looks amazing when you see around 12:00, 50% of your power comes from solar alone.

It is true that solar PV is the largest new build electricity generation component in non-military sources (and, actually, even in military sources, supply lines are difficult to maintain).
The problem is that:
1. residential total energy use is shrinking. Part of this is, in fact, residential purchases of solar PV and powerwalls or similar batter systems that doesn't feed back into the grid, but part is literally the more efficient appliances and lighting of modern homes.
2. the existing base on non solar energy use is quite large. We see the drop of oil and coal and the replacement is mostly natural gas (and also LNG CNG propane etc) for shaping purposes in systems that add solar PV and wind.
3. the cost of solar PV is cheapest in commercial usage (rooftop dead space, think LA warehouses) but most buildings before 2010 were not built to a standard needed to support the electrical and weight components to support adding solar PV, except in a few counties. this is changing quickly, but the lowest cost of solar is industrial scale solar, which costs about half what residential solar PV panels do.
That said, it's good news for the planet. Or, more specifically, the humans on the planet. Earth doesn't care if we go back to dinosaurs, they lasted a heck of a lot longer than humans have.

It's like that in texas too. We used to have 6 good weeks of winter with regular periods longer than a week where there was ice on the ground while I walked to school.
Now, we get a few hours at night of freezing temperatures. But (on topic) we did get 8 weeks of overcast a couple years ago. That would have been a bad case for solar.
That said...

Germany has gotten 85% of their total power generation from solar some days this year and projects that such days will become increasingly common going forward. By 2030, they project year round coverage (which means during sunny months they will have power to spare.).

It ain't your grandpa's solar panel anymore. The system is evolving.
Beware of the Leopard.
So you're saying solar is not some magical energy source? Yeah, right.
Next you'll be telling me Keebler cookes are not baked by little elves in a hollow tree.
I'll see your senator, and I'll raise you two judges.
Out on the bleeding edge, you can already build electrical storage that is maintenance-free, and does not require grid connection. I built a pilot installation for my radio trailer - I'm a ham operator - where the storage is entirely ultracap based. I've got enough out there to provide about as much power as two 110 AH car batteries, which is more than enough to run the three LED lights in the trailer and my 265 watt consume / 100 watt output (on transmit only, it's about 10 watts consumption on receive) radio. I mostly listen, so that's an excellent consumption to supply ratio.
One of the thing that many people don't appreciate about standard solar panels is that they produce energy on cloudy days, albeit a reduced amount; my system never, ever goes down, because there is sufficient capacity to keep it up as compared to the amount of use it gets.
In the future, I expect the cost of ultracaps to come down considerably, and if that happens, the whole battery issue will go right out the window. Ultracaps have very long lifetimes, just as solar panels do. They're not nearly as toxic, either.
For now, I freely admit up front that the cost to do this was not something that is practical for a large installation, such as that which would be required to run a home with a typical 10 KW electrical service. You'd need a lot of panels and a lot of ultracaps (ultracaps are presently at about 10%-20% of energy storage as compared to a comparable size / weight bank of batteries.) However, that 10 KW service is almost always that large to deal with surge demands, rather than constant demand, and that means that you'd need fewer panels overall. The ultracaps are actually far better at delivering surge power than either the grid or batteries, so that cost is only about what you use on average, not peak usage. The converter (ultracaps have a very different discharge curve than batteries do, and require dedicated electronics to produce a steady output comparable to batteries), however, still has to handle the peaks.
I've fallen off your lawn, and I can't get up.
There is not turning off your lights, Leaving your TV on. Buying appliances that have more power vs Energy Star Ratings. Getting bigger stuff...
Just like when Fuel Prices go down, people buy Large Cars and Trucks, when prices get high, they buy the smaller cars or ones that use less fuel.
In college we didn't have to pay (directly) for Heat or electricity. So we left our Desktop Computers on all the time, with the monitors playing fancy screen savers which looked cool. If in winter it was too hot in the room, we just opened a window vs turning the heat down, because it takes less time to warm up again if it got too cold. We would take long Hot Showers...
In short our power usage is based on what we pay. If Solar Energy is very cheap, when we upgrade, we would probably be using more power so will get more power as to maintain your comfort level.
It is easy to fall into a comfortable life style, it is harder to go back.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
Well, in europe people learned how to conserve power decades ago.
This window opening thing is frowned upon very severly.
I know no one who sold his car to by one which needs less fuel because the fuel price changed.
Anyway ... unless I get a new electricity consuming hobby, I hardly can imagine how I need/consume more.
The only thing would be a Sauna in the house ...

All great points, and you're right. Storage is definitely the next hurdle and one that will be difficult to overcome. But we have to start somewhere. It wasn't all that long ago when driving ~250 miles on a battery was considered impossible -- or cost prohibitive at best. It's not acceptable to just throw our collective arms in the air and keep doing what we're doing just because the numbers don't work out today. What SCE and other utilities are doing in this area is important, even if the overall impact seems insignificant right now.
Beware of the Leopard.
My 10 year old PV array is still going strong and has paid for itself many times over. I know it wont last forever but its required no maintenace in that time and im really happy with it. Of course I should give it a wash to get a couple of % back but hey.

If dRumpF says fake news, he thinks it makes him look bad and is in denial. It is probably also not fake.
Only I can judge you.
I suggest you actually read what you linked. Or check out the real world where an early (1980s) solar installation in Sweden was dismantled after 25 years to be found generating within original manufacturing specs. It's absolutely possible with quality panels to look at potential five decades of operation, the worst problem being perhaps catastrophic encapsulation failure (with moisture ingress).

I'm not too sure about that. The cynic in me says that he does it because he doesn't like it and it goes against what he's selling today. To be in denial would mean there's a potential understanding somewhere in there. Until there's some sign of that, I am not holding out hope. After all, does a 3 year old throwing a tantrum realize he looks like an idiot? Or is he only interested in whatever has attracted his attention at that moment and is being denied him?

Actually not as much as you would think. All most all of the technology has been developed. The oil industry has been poking holes in the bottom of the ocean for 30+ years. They have gotten really good at it. The only technology that I'm not sure has come to maturity is the storage part.
The term is called glassfication. Basically the waste is mixed in with slag and turned in to glass. This could be ground up and pumped in to the holes along with a binding agent.
An if you don't want to poke more holes in mother earth just for this issue. Then we can make it even cheaper by piggy backing on oil extraction. If oil exploration comes up with a dry hole examine it for the feasibility of waste storage.
The object is to get the waste so deep in the bedrock that it will eventually be carried into the planets mantel for a few billion years. But the important thing is to get it out of the biosphere.
I read at +2. If your post doesn't reach that level I will not see or respond to it.
You are correct. I should have previewed that before I posted it.
I should have said is you grind up the waste then you mix it for the glassifictaion process. I would imagine that you want to keep the final product small, say the size of a marble so it can be easily mixed with a medium for pumping. I wonder if ordinary concrete would work for this part of the process.
