Yeah, I've used uni-strut (or Super Strut) in lots of industrial applications but it has its limitations too. You need a special bracket or clip for everything. As you can see, I have a couple outlets and my conduit is strapped to the back board since, NEC requires it to be supported within 3' of a connector. I use 1/4" lag bolts mostly for the hardware. I know this is residential but I cut my teeth in heavy manufacturing. Even certified in Allen Bradley PLC (Programmable Logic Controllers) controls, NEC70E and OSHA 30. Enough of that!
I have 42 solar panels on my roof so, I'm tied into them too. My trench is only ~70' long. Some states don't allow separate meters on smaller properties.
