Across the country, from California to Minnesota and North Carolina, farmers are mulling the benefits of adding solar to their land.

The Department of Energy now provides a “Farmer’s Guide to Going Solar” on its website, answering common questions, and the Department of Agriculture offers grants for agricultural producers and rural small businesses to install renewable energy or energy efficiency systems.

While land-use clashes between communities and renewable energy developers are still around, they seem to have mellowed. Instead, many farmers are getting in on the investment, and solar has proved to be a valuable crop.
