This is harder than it looks.
See those rows of crops? On most farms, you need to be able to drive a tractor through them. I don't mean a riding mower, I mean a giant thing that pulls a tool that's working on 5-10 rows at a time doing things like tilling, seeding, fertilizing, harvesting, etc. If there's big metal pillars every row or every other row, that tool can't be used.
Thus, as pictured, those kinds of panels can only be used on a farm that's not using large multi-row agriculture machinery. That means it'll work for small family farms but not the large ag operations where this sort of tech could really kick ass.
What I would really love to see is more solar over commercial parking lots. That means a million little projects instead of a few huge ones, but think about how much surface area that is overall. It's huge.
The key to doing that is twofold- 1. create a few cookie-cutter designs for the frameworks that can be tweaked for individual projects, and 2. remove red tape from their implementation.
It should be possible for a business to buy off the shelf plans for such a thing, have a local engineer tweak them for the project specifics, and then have a local contractor do the installation, and have this happen in under 6 months.
As it stands, building anything above where humans will be involves a nightmare of engineering and insurance and liability, making it cost-prohibitive for most companies. That needs to get easier. I believe every parking lot should have solar above it- that not only will produce a ton of power, but it'll keep the cars cooler in summer.
Might be a crazy idea but maybe they can just use smaller tractors. I'm not sure if we have the technology to build Smaller tractors. But since they are needed maybe there could be a Lot of R&D to make a tractor that fits under the space available in these installations.
Small tractors are easy. The issue is efficiency. The big tractor is big because the tool it pulls behind it covers ~10 rows per pass. You can easily build a small tractor that does 1-2 rows per pass, but that means you need a lot more passes, which means doing anything takes a lot longer.
