The first commercial PV solar product was nah just in 1909.
See story above, and original article in Modern Electrics magazine in 1909:

EDIT
Since people didn’t read past the headline, the article is about a startup company in 1905 that developed a commercial electrical solar panel by 1909 and was worth 160 million in today’s money.
In 1909, the inventor of the solar panel was kidnapped and ordered by his kidnappers to destroy all information about this solar panel. He was eventually released, although he did not destroy the solar panel or his documentation, he did shut down his company.
So this is a pretty fascinating development considering that at this time period we actually did have early production electric cars that were manufactured in larger quantities than gas vehicles, and now we learn that solar panels were commercially available, at least for a short time.
And the solar panels could generate a fair amount of electricity:
500 volts per 10 square ft, and a smaller demonstration panel that was 3 ft x 4 ft could generate 60 watts of power (10 volts @6 amps).
Additionally, the panels were designed to charge a battery backup system.
I think it would have played out roughly the same. Energy density of fossil fuels is ahead of everything, along with it’s portability. Not to mention no one knew or cared about environmental issues then.
Might have made the transition easier though.
Some cared or questionned it. A local newspaper which is more than a century old, republished some old articles. One of those was about the coal consumption, how luch they comsumed back then, and how it would be consumed in the incoming decades, and asked what was going to be the outcome.
In the 30s, some english scientist pointed the raise of temperature too. It was minimal, but visible.
Exxon had detailed climate change predictions in the 1970s:
I did not read any of your linked articles, but the answer is yes, fossil fuels most certainly would have dominated the 20th century because they are:
- Cheap
- Stable, you don’t have to depend on the sun shining
- Nobody really cared about climate change back then, they were estimating a few centuries and humans… aren’t that forward thinking
Edit: I was beaten by another commentator lol
LOL sorry bro
That being said, free electricity is free electricity. There are so many use cases for distributed small power systems, particularly in rural areas. I would bet that early solar could have found widespread use while yes, fossil fuels would still have dominated.
It’s not free though, solar panels back then would be prohibitively expensive for the number required to get any amount of useful power. I suspect they weren’t all that durable or weatherproof either, so that’s even more cost in periodic replacement.
Meanwhile your neighbour is burning this black stuff that’s almost as cheap as dirt and getting huge amounts of energy out of it.
Coal required someone to dig the mine, build the railroad and powerplant, not to mention build the electricity infrastructure. That was a huge expense and made a lot of people rich.
We do t have a cost information to judge these by, but the infrastructure costs were certainly far lower for solar panels.
I fully agree. In cities and places with a grid, fossil fuels will absolutely dominate, while rural grids/independent homeowners could use solar. However, I do think the cost of acquiring such panels could be prohibitively expensive for some rural homeowners.
Yes, but in 1909 they didn’t have a grid yet.
These solar panels must have been using some older technology fundamentally different from the one used in current solar panels because the PN junction, basis of the photocell, was not invented until 1939
Likey also didn’t contain rare earth minerals - no where near as effective but could have been less damaging and easier to make.
Then again, could have been a combination of arsenic, asbestos and cocaine so who knows.
I was too curious:
Cove’s device was a sort of thermocouple, and thus not based on newly-discovered natural processes or scientific principles. In the patent application the device was described as follows: A thermo-electric battery and appurtenances comprising a block of incombustible, non-conductive material, a series of pairs of elements comprising a plurality of elements formed of an alloy of antinomy and zinc, and a plurality of elements connecting said antinomy and zinc elements, said elements connecting said first-mentioned elements being alternatively of copper and of an alloy of nickel, copper and zinc.

No such thing as too curious… unless you are a cat. Little dangerous there.
If im reading this correctly, and translated to english:
-
non conductive block
-
two different alloys - zinc and opposite to zinc (antinomy) v copper and nickle/copper/zinc.
-
assuming light hits, produces difference between metal and opposite metal, results in current flow through wire to equalize. Not sure how rare earth Nickle and zinc are, but suppose its not cobalt.
So it’s a Seebeck Effect generator and really isn’t what we’d call a solar device today.
Seebeck Effect
This is how fridges work in reverse right? Apply current and make one side really cold?
Fridges work on gas pressure - compress a gas it heats up, decompress a gas it cools…
Wait… then what am I thinking of? I’m sure this effect is used somewhere
The device you’re thinking of might be a peltier or thermoelectric cooler (TEC). But yes. They’re way less efficient than a vapor compression refrigerator, though.
Ohhhh… Thanks!
Like the very small fridges that work for a single soda can? Refrigerators use the liquid/gas transition to move heat around. It’s much more efficient.
The only real advantage of Peltiers are simplicity and size.
Sorry - above my pay grade knowing what that is. Got a bit of education to get through.
Basically when there’s a temperature difference been two different metals that are touching a small current is produced. You can also go backwards and use electricity to create a temperature difference (Peltier Effect).
They have niche applications because the effect is pretty small. Hardly a realistic substitute for solar panels that use the photovoltaic effect.
Does this mean - in theory - I can put one metal plate out in sun, one in shade, connect with a wire? Or is it a contact surface area thing?
Nickel and zinc are very common to my knowledge. And much easier to mine than lithium

What is the typical conversion efficiency of a solar powered thermocouple?
“Cove presented his second solar electric generator there in 1909. This 1.5m2 panel could produce 45 watts of power and was 2.75% efficient in converting solar energy into electricity.”

I want to read more about this, as there is some speculation that the guy may have invented an actual PV panel. Difficult to say without more research… He was also a prolific inventor.
Photoelectric efficiency was pretty bad back then. It had only been discovered in 1887. Einstein had just studied the photoelectric effect in 1905 and won a Nobel prize for analyzing it in 1921.
https://www.aps.org/publications/apsnews/200501/history.cfmIt wasn’t like getting rid of the guy would’ve destroyed knowledge about it or the potential for the business. The devices were listed in the patent office and the technology was public knowledge. It just couldn’t compete with cheaper and more energy dense sources like oil. Electric cars were a thing even in the late 1800s but the technology was so poor they lost to internal combustion.
Interestingly, my parents remember electric milk delivery trucks in the 1950s & 60s.
The technology could have been improved if there was investment. Just look how much has been invested in ice vehicle drivetrains… It’s a wonder they work at all!
Yes.
Doubtful that it would have been very different. We would probably have more solar for home electrification. But with storage options being even less viable back then, we still would have needed a grid.
but the biggest benefit for fossil fuels were cars. And there I don’t see how EVs would have been viable (yes, I know there were prototypes back then)
Fun fact - for a short time, there were more electric cars than gas:
“In 1897, the bestselling car in the US was an electric vehicle: the Pope Manufacturing Company’s Columbia Motor Carriage. Electric models were outselling steam- and petrol-powered ones. By 1900, sales of steam vehicles had taken a narrow lead: that year, 1,681 steam vehicles, 1,575 electric vehicles and 936 petrol-powered vehicles were sold. Only with the launch of the Olds Motor Works’ Curved Dash Oldsmobile in 1903 did petrol-powered vehicles take the lead for the first time.”

Here’s a whole lot more detailed information with sources:
https://www.resilience.org/stories/2021-10-21/how-to-build-a-low-tech-solar-panel/
Whoa, thanks for the link! Fascinating! So this WAS potentially an early non-silicone PV panel.
“If Philip Pesavento’s historical account and hypotheses are correct, George Cove set out to build a thermoelectric generator but accidentally made a photovoltaic generator – a PV solar cell.”
“By mid-1909, Cove had moved to New York City, where he presented his third prototype, a solar array consisting of four solar panels of 60 watt-peak each, which charged a total of five lead-acid batteries. The total surface area was 4.5 m2, the maximum power output was 240 watts, and efficiency rose to 5% – similar to the first solar panel presented by Bell Labs. [18]”
Sadly, reference #18 does not actually list a reference but a statement by t Mr. Cove which is impossible as he is currently deceased.
ITT: people who didn’t read past the headline
Maybe, but the result is the same. The arguments in the article sound good but aren’t really that compelling. The points people make here are good.
This is one of the rare cases where the answer to a headline question is “yes”
Put up a shitty leading headline and this is what you’ll get.
You weren’t allowed to put your own headline up for these types of posts.
The point is, the behavior is to be expected, regardless of how it got there.
