You need way more research and to come up with a business plan and cost analysis to see if this is even worthwhile to do.  You're picking numbers out of a hat and I don't think you've really determined if what you're attempting to do will even be profitable.

You might be better off just building a data center and hosting other people's miners and giving them a reduced electrical cost thanks to your Solar Panels.

Realistically though, solar panels in Ohio are not optimal (I live in the same State, near you) and we get a LOT of cloudy weather, not to mention... Snow.  So it's not a great idea.  And electricity here is not that expensive compared to most of the rest of the world.   (Though not all of it.)

You need to factor in cooling costs, and whether or not your local power company can deliver the kind of wattage you need to your location (Which sounds like a farm out in Medina or Elyria something).   Your property needs to be zoned for that kind of activity as well.

I wouldn't mind having access to a low cost data center near me.  But the margins on mining are very thin, and if you think you're going to spend half a million building this thing and then make that back through mining you're nuts.
