The sun will soon help power some operations at the Biltmore Estate: The company is preparing its new solar farm — a six-acre, 1.5 mega-Watt system of some 5,000 interconnected solar panels — for action next week. Among the largest of such installations in Western North Carolina, it can be glimpsed along Interstate 40 in Asheville. The final electrical inspection was set for Wednesday, Dec. 14, and project managers hope that the installation will be commissioned for operation the following week.

Why is Biltmore getting into solar power generation? According to Chuck Pickering, Biltmore's vice president for Agriculture and Government Relations, give the credit to the early vision of George Vanderbilt, who aimed to develop a self-sustaining agricultural operation that emphasized stewardship of the land and its resources. Vanderbilt was interested in cutting-edge technology in every aspect, Pickering argues, from sustainable forestry to advanced agricultural practices to electric lights and laundry drying racks — and all back in the days when electrical power was new.

“We are looking at ways to really make a difference, both within our agricultural operations and our energy supply," says Pickering. "This particular array is one of the most advanced systems," he continues, explaining that it was built and engineered by Sun Energy1, a contractor out of Mooresville. "The system uses Bosch panels, chosen for their track record for performing in Europe, where cloudy days can impact solar performance. We finished our testing yesterday," Pickering reports, "and they’re testing at 12 percent above norm. They’re running great.”

Pickering says the goal is for the entire Biltmore Estate to be net zero — that is, producing as least as much power as Estate operations need, plus excess power that is put back on the grid. “I would like to see that within five years, maybe faster," he says. "It just depends on technology and the economics of it.”

The power generated by this array will service the buildings at Antler Hill Village, the Estate's newest commercial development. Situated on about six acres, and visible on the south side of I-40 as it passes the Estate, the array consists of 19 rows of carefully calibrated racks, each holding twenty-eight 240-Watt solar panels, tilted to maximize solar uptake. The installation is laid out on a slight slope that allows the racks of panels to be placed as close together as possible without casting a shadow on the neighboring row.

This power project is just part of Biltmore's larger sustainability efforts, Pickering points out. “We’ve been working hard for several years to put [green] things into practice,” he says, from the basic principles of reduce-reuse-recycle, to systematic plans for every department to reduce its carbon footprint. Estate staff and owners are now looking at the prospect of a solar thermal installation for the Biltmore Winery.

But they're taking their time. “We do an extraordinary amount of due diligence on projects like this,” Pickering says.
