> Especially, but not exclusively during unexpected power loss

Though in my experience as a technician installing 2.5" consumer grade / entry level Kingston/ADATA SSD to several clients, this is what generally will kill NAND flash devices, it's not an exclusive phenomenon to uSD cards.

I have a few running RPi's on premises for years. Ranging from v1 to now v4, certainly the only uSD 3 failures I have had has been with the early models and reliability went up with...... just a No-break power source. Just that.

It seems a lot of people think a sudden power loss it's what's only dangerous for electronics and NAND flash devices but for devices that are highly sensitive to browning down power rails (specially those first v1 raspis) any unstable power source is a rave party from which is hard to get out unscathed.

One of the first things I bought for my Raspberry was a battery hat, it’s great. When the power goes out, it keeps on trucking. I would love to add a solar panel or wind turbine as an extra power source.

Yeah! That has been my idea for a long time! When thought about it, I began looking into devices that can output DC and charge a backup battery but with a variety of input power sources, Solar as main source and line AC as backup. Didn't get that many practical search results.

But it seems what I was looking for are boat chargers. They're meant to provide energy through solar/battery and charge at the same time while parked on a deck. Didn't followed it up though.
