Best would be to run the cabling in PVC conduit fixed to the frame holding the solar panels.
Then run the cabling under the tiling and into the roffspace to where it is required.
Try keeping the solar panels wet for at least two weeks. They should root provided they are in a proper growing medium.
You can also try growth hormones to help them root.
