Wait.....now we’re introducing 3M dual lock Velcro to the mix?!? While I hold that stuff in high regard, I’m not sure I would use it to secure panels to the roof, flexible or otherwise. I don’t think it has a VHB backing either.
I like leaving the option open to be able to swap out panels as needed if one fails or as better, higher wattage ones become available. No swapping things out if it’s directly adhered to the roof with 5200, a little more doable but still difficult with the VHB but much easier if it’s just bolted into a track.
I’ve done it all, I used VHB on four 1’ sections of 2” angle aluminum to secure a panel to our travel trailer without any issue, no tracks, so not much of a choice. The van has them bolted to the roof rack on the CCV too for easy upgrades, and I used to have a setup on the SMB poptop using brackets into the Thule tracks, which can also be added to your top.
Good luck, but I’d reconsider using dual lock
