Really? That’s the dunk you were trying to work towards?

The animals keep the grass and weeds under the solar panels trimmed, saving on mowing. This also provides food to the animals, who love grass, meaning you don’t need as much hay during the spring/summer seasons. The cows get fed, the solar field gets maintained, and the farm gets energy output as a bonus.

Leave a grassy field untrimmed for a few months and guess what you wind up with? A hay field.
