I used these Fast Jack E- Series 3"
Professional Solar Products Inc. (Prosolar)
They don’t need to be for a metal roof. You screw the lag bolts into the roof trusses.

The clamps that are designed for metal roof are not that great and they are expensive.

I did call them and talked to one of their engineers and explained what I wanted to do to them and he said that would be fine.

As long as you are putting lag bolts into roof trusses there is really not much difference between metal roof and a shingle roof. Except you don’t need a metal plate to mount under the shingles.
When I drilled into the truss I injected sealant I also put sealant over the bolt head.

I just looked it up and the second racking I used was renusol VS rails
Solar Mounting Systems for Flat Roof and Pitched Roof
This racking was even cheaper and went up faster. I used there L foot bolted with lag bolts into the roof trusses

Here are some pictures of my racking install. As you can see you just make sure you are on a flat part of the metal and also hitting a roof support.

If you put the microinverters back to back it saves on cable. It also lest you buy portrait and not landscape engage cable witch is cheaper and has lower resistance loses.
