Thanks LB. Based on the first picture in my original post, it looks like I have an SAE to MC4 at the roof entry and then two MC4 connectors to the solar panel wires. Once I get up there and remove the existing Sikaflex maybe there will be enough slack in the wires to just use a pair of MC4 connectors and seal the hole.
