Hello, this is my first post, but have gained from this forum for some time now.
I'm helping a neighbor upgrade his system. He's getting (12) new bifacial panels. I'm designing a ground rack for him. If you'd care to, I'd love any feedback. See any problems with my design? Think it'll blow over? Gut check? Any feedback is much appreciated.

- Snow loads are minimal. It'll snow a foot at most here, and then melt.
- Wind can be stiff, but we have no hurricanes or tornadoes here.
- All of the fittings are standard unistrut fittings.
- Fitting attachment to the piers is deep jbolts embedded, not drilled expansion bolts.
- The only non-unistrut stuff besides the concrete is the diagonal cross braces, which I'm thinking I'll use something like ~1-2"dia galvanized metal fence pipe.
