I got the "solder cell" to work with Epsom salt and distilled water.
I did alot of research on lead acid battery chemistry yesterday and kept bumping into sites that talked about rejuvenating weak batteries using Epsom salt and distilled water. Since I already knew that the Alum (aluminum sulfate) worked on my solder cell I wondered if maybe Epsom salt (magnesium sulfate) would work. It did.
I also looked into lead alloys --specifically the lead acid battery plate alloys and solder alloys. I am pretty sure now that my cheap solder is mostly lead with only a slight amount of tin.
Last night I hooked up one of my "Penny" oscillators to the solder cell that I had charged up with the 3v solar cell. It ran the light all night (at a low setting) and still had 1.4v on it this morning.
I made a 4 sinker cell that is also performing well but oddly has a negative
electrode that is black and a positive that is dark brown. That sinker metal might be some kind of alloy also instead of pure lead.
According to my research the lead plates in acid batteries are usually lead with a slight amount of tin and antimony. The sulfate (SO4) appears to be the chemical player in why my simple cells work with either an Aum or Epsom salt electrolyte---but I'm just guessing.

Maybe you could find some wheel weights or lead sinkers and try it again. This cheap solder that I found might be not that common.
