I'm planning to DIY this vertical solar wall 90ft wide and 24 ft tall. 30 ft I beams will be lifted into the excavation holes and the foundation piles will be poured around them. I think the hardest part of the construction will be the erection of the columns in a way that is perfectly planar. Solar panels aren't very tolerant of bending stress so I need them to be planar within a 1/4 inch more or less. I am thinking to install scaffolding opposite the crane truck position so that I can reach the entire I-beam area from top to bottom. But the challenge remains getting those beams perfectly in plane . The I beams will be prefabricated with bolt holes for the horizontal support rails. The horizontal support rails will be HSS steel with bolting plates set at each column . They come in 20' lengths and 10' lengths .So I am thinking at the very least, I can bolt the HSS to the I beams to provide substantial alignment. I also have a builders scope level. Just posting here about it to see if anyone here has experience in this matter. Anyone have advice? Will post more details.

>>2994918wait a minute lol 30ft pole 24ft height perfectly planar construction so this is a wind up then?anyway actually getting posts plumb and plane is easy, you put the two end posts in first, use a plumb to get them vertical.now before you fix them in, run a string line between them.use the string line to rotate the post so the string is flat to the face of the postthen with a string line top and bottom between two fixed posts, you can offer up all the intermediate posts to the string line before fixing them.next: don't bury steel anything. concrete footers and then fix the steel to the concrete. unless you live in the desert. 24 ft is not to be fucked with. if you want i guess you could contract a piler to do it.also solar panels usually are installed at an angle. i.e. pointed towards the sun.

>>2994964Steel has to be embedded in the post in this case for bending moment resistance. >angleThis is a winter array , we already have enough angle arrays for the summer
