Rare earth minerals are often all over the place, they are just very messy to get to and that gets in the way of EU pollution regulations. China is not a sole producer - they are just cheap enough to make mining elsewhere not worth the hassle. That will change fast if they bottleneck the supply.

There's a big find in Norway, largest in Europa according to new estimates[1].

The updated estimate shows that the total rare earth oxide (TREO) content in the mapped resources (Indicated and Inferred) has increased from 8.8 million tonnes in 2024 to 15.9 million tonnes in 2026 – an increase of approximately 80 percent. For the first time, parts of the resource are also classified in the Indicated category, reflecting a higher degree of geological confidence

The WSP report further shows that the proportion of neodymium and praseodymium (NdPr) can be increased from approximately 17 to 19 percent of TREO. These REEs are regarded by the European Commission as the most critical raw materials in terms of supply risk and are important in the manufacturing of permanent magnets for EVs, green energy and defence.

There's no mine there yet though, and they haven't yet determined if it's economically viable. So yeah.

And once enough panels start nearing the end of their lifetime, it's likely that we should be able to recover nearly all the rare earth minerals from them with proper recycling. They don't actually get used up the way, say, fossil fuels do.

Solar panels contain negligible amounts of rare earths, compared to the amount used in wind / gas / steam turbines. They're also still used in oil & natural gas refining (though less than in the past).

Fossil fuel generators are most reliant on them, wind less so, solar barely at all.

Oh, I completely agree—but they're so frequently used as a gotcha for why the rise of solar is just trading one "foreign master" for another. "Oh no, solar panels rely on rare earth minerals, so that means you have to kowtow to China!!!"

And it's true that there is some in them, so it's good to have at least a long-term answer for how we deal with them.

It's the old saying about a man and fish and giving vs. teaching.

Solar panels bought now, at least the quality glass-glass kind, doesn't really go bad in a way that makes them depreciate at-all-quickly. If in locations that are not themselves at a premium, so lower yield only matters if maintenance overhead per yield becomes so bad it's cheaper to replace& upgrade, they can be expected to stay there for 30~50 years depending on how fast they'll mechanically fall apart after their warranty expires (which is expected to be the duration until which most stay alive). I'd guess something like an agricultural east/west fence install would stay more towards 50y and get individual modules replaced when they break, as they're easy to get to unlike roof/wall installs and the like where they're hard to get to and given they are very low complexity in mounting system ("fence panel") there's little engineering complexity in retrofitting a plain new future panel of the same physical size and sufficiently similar voltage/current.

Solar panels hold and work for more then fifty years..
