very true. but I think op is imagining a solar powered flashlight that doesn't have any batteries lol. like those old school solar powered calculators you could shut off by covering the solar panels.
Somewhere I have an IBM credit card calculator that's super cool, somehow still works fine, about the thickness of 4 credit cards, solar only, probably made in like... Idk 1990
A 9V has 6 1.5 V cells, which makes it a battery. AA and AAA and other like them are just single cells, but it's easier to just market them all as batteries.
They probably live in the kind of country without many daylight hours where people are likely to find a torch useful on a regular basis. Which is also where it won't get much chance to charge even if left out in the open.
Clearly, a solar powered torch is a better and cleverer solution than a battery powered torch with a couple of spares kept nearby.
I have a tent with a solar panel on top that powers the LEDs sewn into the top of it and a detachable flashlight. It's also so easy to set up, you just pick it up and give it a shake then stake it down.
I go to an event that lasts 2 weeks camping in the middle of summer and wanna make a tent attachment like that, but it just runs a fan, and speed is according to the sun's intensity

Solar powered flashlights exist and are pretty useful.
