Wiring Solar closer to 12v fuse panel vs. directly to batts?

I went through all the installs. None are quite exactly my situation, but they are all informative. Wow some of them are not my style, I really want the wiring to be invisible. I am hoping I might be able to fish the wires through the tv antenna cable route. I have yet to see an install that tried it. Off to look for a tv antenna mount diagram because the cable seems to be stapled or something.
