To some extent that falls into the category of "fiddly details." Solar panels are probably not the best choice for use alongside bulk harvested crops like corn, wheat, soybeans and even potatoes, but an awful lot of "produce" crops are harvested by hand.

The reason I say "fiddly details" is because questions like "what's the best spacing between rows of panels" and "do I plant under the panels or just between rows" can be decided as people look into available equipment, land prices, crop variation and flexibility, etc.
