Also, solar panels put out a lot of heat. A cheap sheet of plastic corrugated board that you can get from Home Depot, cut to fit below the panels, will provide air flow and lower the roof temperature.
Good luck!

I'm assuming these are flexible panels, not rigid framed panels. I'm not sure why you're biased against two-sided tape. 3m VHB tape has much more holding power. Eternabond is a sealing tape and has very little tensile strength. If the top layer is damaged, it's essentially zero.
Personally, I'd adhere the panels to the roof with VHB tape and protect the front edge with Gorilla All Weather Outdoor Waterproof Duct Tape. It's UV and temperature resistant and is stronger and much easier to remove than Eternabond. For this application, you don't need the sealant properties of Eternabond. I've had some on my van for several years an it looks like new and it's parked outside in the Sacramento area summer heat.
I'm not anti-Eternabond, I use it on all my roof fittings (vents, etc.) that require sealing against leaks.
