I'm trying to figure out the torque specifications for the clips on my 410W solar panels, but there's nothing mentioned in my manual. I was thinking of using around 8 pounds, but I'm worried about making them too loose or over-tightening and damaging the panels. I'm curious to hear what others typically use for torque settings.

For most solar panels, the torque spec ranges from 13 to 17 foot-pounds. That's a pretty standard range, so if you're tight around that, you should be good.
Last year, I set mine to 12 foot-pounds, and it seems to work fine. That’s a solid number to aim for! Definitely agree that the specs should be included in the manuals, though!
Thanks! That sounds like a good number. You'd think they'd include that info.
Just a heads up, the panel itself might not specify the clamping torque. I usually go by the manufacturer of the mounting hardware. For instance, the Iron Ridge UFO clamp recommends about 80 inch-pounds, not foot-pounds, so it’s worth checking those specs.
Thanks for the info! It's a bit frustrating not having the specs on the paperwork.
