Did you attach the 2nd panel to the yellow & black? I was hoping to still use those for some exterior lights. I was wondering if I can daisy chain into the existing solar panel easily?
You can use one harness for both solar panels. I just chose not to. I ran a separate wiring harness from each solar panel to the Jackery because it has two solar input connections. This avoids having to combine the panels into a single circuit, keeps each connection within its applicable electrical limits, and makes troubleshooting easier. It may also improve performance when one panel is partially shaded.
