    It's meant to sit flush but first things first, need to see if running jumpers make the panels work again.

      Best things to use is component leads work real good this type of repair

      Unless you have battery tabbing wire on hand would be best thing to use

        Ok repaired two broken traces and I quickly measured over 5v under my led lit magnification lamp. Will try today under proper sunshine to see what the panel puts out.

        I used some really small gauge insulated wire to bridge the traces. I think I will redo that work after a little fact finding with the panel itself now that it's working.

          After you finally fix the breaks seal the repairs with marine epoxy I would also apply some over just the tabbing material only you do not need to make very thick but you need thick enough to seal it so moisture does not continue eat away at it

            I brought it out into the sun today and registered 6.9v unloaded.

            Next step (after making the repairs permanent) is to decide which electronics to use and what type of battery.

            Is a Li-ion cellphone battery a good choice for this application ?

              I have a solar panel I wish I could repair, would be nice if it's just the interconnect but the tracks on the wafers themselves look oxidized. Should take another look at it, and without the charge controller... (BTW, problem I'm seeing is that it cuts in and out, sometimes generating power but sometimes not, and sometimes hitting the panel makes it work again...)

              Sort of spoiled now with the 100W panels, the bad panel is probably no more than 5W or so if that much -- drop in the bucket compared to trying to get the 100W panels optimized.
