I would not be surprised if many manufactures defined "solar ready" as... "has a roof". :D
Seriously, those wires are probably what they define as solar ready. They probably terminate next to the converter. Everything I have read says that the solar controller should be put as close as possible to the solar panels. So you put the solar controller in the cabinet then breach the roof to run wires to the solar panels. I have also read that even a partial shadow on a single panel can greatly reduce the output of a bank of panels.
