A friend of mine wants to know the environmental impact of a solar farm.

Why is that? I have been a landlord for thirty years and my leases specify the property would be returned in the same condition, otherwise the tenant does not get the security deposit back. I would assume for a transaction of that magnitude and length that the OP's friend would get some professional help drafting or negotiating terms.
I've been a landlord for 25 and have worked on many comercial sites. My idea of cleanup and someone else's seldom matches, and most commercial cleanups I've seen are typically done quickly with little attention to detail (if not burying some of the mess, only to be found long afterwards). Obviously this is a generalization. Regardless, if this were my property, the aftermath would be my biggest concern.
 
Yes, residential has its issues too. That is why I get a security deposit. I assume that is the same with commercial leases?
The idea of a performance bond is likely better than a deposit; I doubt you could get cleanup costs for 25 years out as a deposit.
 
Sonoma Raceway isn't bum frak Missouri or Arizona or Nebraska. I stand by the argument that they are impractical for much of RURAL North America unless you want intensive management. Homesteader/small holder types, sure. I don't see any farm of a decent size running them because they are too intensive to deal with. They die if you look at them the wrong way and they have no built in self-defense.

Edit: I would love if this weren't the case as I love lamb and mutton and it's expensive here.

2nd edit: methane/smeshane. Grassland needs ruminant animals for healthy soil...and there's no longer millions of bison to perform this function.
Ive seen what a pack of wild dogs can do to half a dozen sheep in a few minutes. Killed them all. A horrible, bloody mess and dealing with disposing the carcasses was a nightmare itself.
My neighbors quit 4h after that.
 
Some general thoughts.

Use bifacial panels to allow some light to penetrate to the ground beneath (and to harvest more power.)
Use ground screws for mounts since they are easily removed.
Choose a height based on what you want to do with the ground beneath. For sheep, you are going to want to locate feeder cables higher than they can reach.
Avoid trackers. They come with a significant amount of limitations on elevation changes and row spacing, and they can leak.
Set row spacing to allow sunlight through.
Do some hardscaping to ensure that the front edge of the panels (where they drain) will not erode too quickly. Could be as simple as planting tough grasses there.
 
The limit will be they own creativity, it's possible (as an example) to build a vegetable garden below the solar panels if it's high enough. I don't see much damage besides the space occupied on the field. It isn't like the solar panels will release toxic gases or chemicals while the time passes.

Most plants don't grow well in full shade.

Investigate the run off from rainwater of solar panels.
 
Agrivoltaics.

From the World Economic Forum:
  • Agrivoltaic farming is the practice of growing crops underneath solar panels.
  • Scientific studies show some crops thrive when grown in this way.
  • Doubling up on land use in this way could help feed the world’s growing population while also providing sustainable energy.

It's a niche thing but can work well in some areas.
