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.”
Though there are far more cattle than sheep in the U.S., their size poses challenges at solar sites, where both expensive equipment and the animals, which can weigh more than half a ton, must be protected.
Solar panels often pivot to near-vertical angles to capture the sun’s rays, leaving little room underneath for cattle; simply raising the panels is cost-prohibitive because of the amount of steel required. So Silicon Ranch raised the panels a little but also developed software that workers activate to turn the panels close to horizontal when cattle are grazing, giving them room to wander, said Nick de Vries, the company’s chief technology officer.
Workers rotate the cattle — currently 10 cows and their calves — between paddocks every few days so panels on the ungrazed portion of the site operate normally, generating a supply of roughly 5 megawatts of electricity for Middle Tennessee Electric, a rural electric co-op.
