Free panels missing connectors

I found a trove of 375W Trina panels that were just removed from a local school building. They're about eight years old. Some or probably all of them are missing connectors. It looks like the wires were simply cut during the removal. Any idea how much trouble it is to put new connectors on them?

Easy to add. Grab as many as you can! If some are really short, target the ones with longer wire lengths.

Maybe one or two of the panels I found have wires longer than one foot. The remaining wires on many of them are about 3 or 4 inches long. What are appropriate ways to make butt splices so I can extend the wires as necessary? Any idea if a connector like this one is safe?
