I have heard from a couple farmers that some venture energy corporation will pay a yearly fee to put panels on the farmland, which is probably the 20k/year he gets paid from a corporation like that. I doubt he's selling the power directly, nor was able to invest money for all those panels. He just get's a check every month. He also doesn't know the risks he's taking allowing that.
