I have a few solar panels/cells lying around that I've gotten from a pack of solar powered garden lights.
The marking on the back of the panels say: Excell EXC53.5*53.5 However I'm not sure if the last "L" in Excell is part of the name or just a graphic part of the logo. The last "L" has two rays coming out of it. The numbers are consistent with the panel/cell size in millimetres.
Anyways I can't find any datasheets for the given info, so before I go fry anything, is there a way to get the absolute maximum ratings for current and voltage?
Any other tips that might be useful when working with unknown hardware would also be useful.
