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.

Sure that does work but it’s not efficient.

Thermal solar generators do exist but they use a liquid as a heat transport mechanism. These use mirrors to focus the sun into a single point. In general you get more efficiency when there’s a larger temperature difference.

You could also get infinite energy by digging a deep hole since it gets hotter there deeper you dig. It’s just pretty expensive.

Geothermal is the solution we need more of.
