Ok, I didn't really string 10,000 of these mini solar panels together; yet. Psych! But you could, since it's always the cheesy battery that goes out first in these, and not the panel. The LED is usually fine too, so you could also replace the battery, but it needs to be a rechargeable one, so the benefits gained here are dubious.
I also lack a house to power, as I have committed to being homeless (more fun, anyway) until I can get an earth ship built on my own permacultured land; but that's another story. I have begun collecting these, a couple of years ago, stashing them at friends' or family's houses in whatever locale I happen to be in.
The LEDs may be saved for other projects, and they are pretty tolerant of voltage variations. The body of the light, with the top removed, makes a great rain gauge or mini vase, or you can stick them back out on the driveway border and fill them with glow stick stuff to have another temporary light, for as long as it lasts. The black stem makes great predator habitat for the garden, and I bet you could come up with about 50 more uses to keep these out of our landfulls. Start collecting!
