we have a 100w Zamp flex panel and want to add a second panel. these pix show how the current panel is wired. anyone here know what I need to connect the second panel to this setup?

Is your panel plugged into a charge controller?

You should be able to cut the wires and splice them together anywhere between the panels and the thru hull connection. I have 4 90W panels connected that way on my fishing cabin with a 15A controller that I've used without a problem for at least 10 years. The wires all come together in a junction box with one set of leads going to the controller. Solder the connections together and finish with several layers of waterproof tape.

Just to make sure, yes about the cut, but make sure you solder the joint and if possible use heat shrink tubing line with glue, instead of the tape.it will be done for good. 😊
