Excellent. That's just about exactly what I have planned. At 39" x 61" the 3 high x 4 wide will fit the 10 x 20' footprint. Have considered sched 40 pipe for the lateral supports to secure the unistruts like you have. Thanks for the photo example.I gave a lot of thought about making an adjustable tilt and after seeing the numbers, it is not really worth it. Something like 71% ideal production without adjusting and 73% ideal with adjusting seasonally.
I built a 6 post (4"x4") stand for 12 large panels. I put 2, 2"x4" on the taller back legs for braces. These were diagonal from the center rear post to the outer rear posts. I could shake it pretty well before the bracing and after the bracing, much stiffer. Mine were 3 high. 4 high, maybe bracing front to rear would help. Try to shake it like a strong wind would and see where bracing might be needed. Also, I have seen metal corrode from the chemicals in the treated wood where it contacts steel, even galvanized. Maybe the galvanize was bad/cheap. I would consider a piece of roof felt or something like that on the metal to wood interfaces. I might have some photos of my wood mount. It was built temporary and then removed when I got a steel pipe structure built. Nothing wrong with wood, just was not my real plan.
edited...found the photo. correction, mine was 4 high, 3 wide in landscape orientation.
