Due to the insane heat problems mentioned up thread, I removed my flexible solar panels and scraped off all the old VHB. If you choose to mount flexible panels, I recommend using less VHB than I did. :
Designed a new beef-bar based roof mount. I used 2020 extrusion to keep things light. The flexible panels have a single layer of coroplast underneath to help stiffen them. I really didn’t want to use the beef bars, but when I found they were only like 7lbs each and I already had them, I changed my mind.
Made all the brackets and mounts and some custom metric track nuts. Special thanks to a couple special people here for helping out with info.
Here’s the rack flipped upside-down.
Took way longer than it should have, but I managed to build and mount the same panels rigid-style.
I’ll post some more pics and detail some other time.
