Seasons greetings from La Paz, Mexico. ... They are thin foil and already damaged

across the joint... Not quite sure of how that would work in detail,
though...

Any ideas out there?

Thanks!

Solar panels are often made with soldered copper tape busses.
So copper tape and solder would be one way to go.
There is a siver loaded epoxy that can do reasonably well in thin
layers. It's expensive, naturally.
