Solar ranch in Tennessee aims to prove grazing cattle under the panels is a farmland win-win

CHRISTIANA, Tenn. (AP) — From a distance, the small solar farm in central Tennessee looks like others that now dot rural America, with row upon row of black panels absorbing the sun’s rays to generate electricity.

But beneath these panels is lush pasture instead of gravel, enjoyed by a small herd of cattle that spends its days munching grass and resting in the shade.

Silicon Ranch, which owns the 40-acre farm in Christiana, outside of Nashville, believes cattle-grazing is the next frontier in so-called agrivoltaics, which mostly has involved growing crops or grazing sheep beneath the panels.

The solar company debuted the project this week and will spend the next year working to demonstrate to farmers that much larger cattle also can thrive at solar sites. If successful, advocates say, that could jump-start new projects to meet the soaring electricity demand driven by rapidly expanding data centers — without contributing climate-warming carbon emissions — and help cattle producers hold onto their land and livelihoods.

“Solar is one of the most powerful tools we have for cutting emissions and ... is cost-competitive with fossil fuels,” said Taylor Bacon, a doctoral student at Colorado State University who has studied ecological outcomes at solar grazing sites. “I think we’re starting to see enough research that, when you do it well, the land use can be more of an opportunity than a downside.”
