[QUOTE="HedgePig, post: 529667, member: 35203"] I hope the title was self-explanatory but I was hoping someone might give me a few pointers on how to test a handful of used solar panels I am going to see tomorrow? Aside from the more obvious things I can think of, like cracked glass or rust or damage, how do I safely test each panel to make sure each is actually working? I assume the plug in bit will have a + and a - and I can simply hold a multimeter to them and hold the panel in the sun? Am I going to zap myself? Do I just measure amps and volts and multiply to get watts? And is there any way I can see how much each panel will have degraded from when it was new? I am going to assume I can't do any of these things, but certainly I hope some of it is possible. Any suggestions welcome? HP. [/QUOTE]
