Title: Repair
Notes: This panel had been under (salt) water at Yampah. The junction box on the back was all rotted out. I scraped the box off and the four junctions to the two 6V cell strings were still good. I soldered wires to the junction pads and added a screw terminal with two diodes. The panel was 20V and 4.5A in the sun. I cut the structure out of the junction box and reglued it to the back on the panel to protect the wiring and screw terminal. I think this panel is good to go.
