Re: [RE-wrenches] TJI rafters
If you can take multiple 1/4" lags, you can consider the Hollaender Speed Rail square flange. I have used this to built steel pipe rack, then attaching solar rail to the pipe with u-bolts.

Re: [RE-wrenches] TJI rafters
I am pretty sure if you look a the TJI specifications for holes and notching you have just about zero options when it comes to using them to resist an array's uplift. Blocking is about the only option unless you use the attachment method that secures each module to the roof's plywood sheathing.

We have done different things, but simple solution is to add blocking and lag into that instead and avoid the TJI's.
