I tried well nuts for my solar panel mount (using Z mounts). They pulled right out.
Well, 17 years later it's obviously too late to argue about how exactly you did the install... but in my limited experience (putting several of them in last fall/winter), on the first attempt (or two) they *did* pull 'right out'. Turned out it was a mistake on *my* part, and when I went back and did it correctly, they held very solidly.
The metal version aka 'riv-nuts' should work at least as well, with the slight difference of not being inherently water-tight. Since most people are going to cover everything in sight with some kind of sealant, it's debatable whether that's worth it or whether it's better to go with some thing that is mechanically stronger like you did.
Either way works.
What was your mistake in putting in the well nuts and how did you do it correctly? I distinctly remember drilling the proper size hole, inserting the well nut, and tightening the screw. In my case, the brass insert in the rubber pulled out quite easily.
