Trying to run solar cable from roof into trunk without drilling

I have a roof top tent currently on my CX-5 (2017 GT) and I'm looking to add some flexible solar panels to the top so I can power a small fridge in the trunk for extended camping trips. Currently trying to find a nice route to run the external solar cable into the trunk. There seems to be enough of a gap where the trunk meets the roof to slide the cable in, however I can't seem to find a nice weather-proofed way to then get the cable into the trunk.

I've seen videos where people just slide the cable under the trunk's weather seal strip, however this adds a big bump to the seal and doesn't look great. Alternatively I could cut a notch in the weather sealing and then add some Sikaflex/sealant around there to re-seal the notch. I've also seen someone go behind the rear lights, however there's another sealed off grommet that I can't really access unless I cut it and reseal it after.

Anyone else have some ideas before I start carefully cutting and resealing some existing sealed grommets?
Thanks
 
I've seen a product consisting of flexible solar panels on the hood, and the cable runs down through the windshield cowl to enter through the door area. I saw it on facebook, but I can't recall the name.

Another place might be where the cables for the trailer lights exit under the rear bumper.

Let's see pics of your car camping setup 😁

Could your cable in through the grommet at the top of the tailgate where the wiring for the tailgate goes through?
