A much better solution, sheep. Have a few friends doing this.Weed/tree control needs to happen. Without it they would shade the panels. Herbicide is the cheapest way I imagine.
If you want to know about returning ground to production look into what it takes to return conservation reserved program land back to production. There probably is a good bit written about that. And with grain prices up farmers are probably interested too. Guess that you would see reduction in yields for a while. When we have broken out sod it takes 10+ years of farming to make similar yields. All dirt is not equal.
