Solar Panel Fence Powers Farm
 ✖  |
Irish dairy farmers are putting their north/south fence lines to good use with solar panels on each side. The vertical bifacial panels concept was developed by Next2Sun, a German company, and adapted to Irish farms by Sunstream Energy owner Gene Hourihane. Instead of covering an area in panels, it harvests the sun.
By mounting the panels vertically on a specially designed frame, the resulting power curve has two energy peaks with a trough at midday. Hourihane says that type of solar production is well suited to dairy farms.
“They have high variations in electric loads, especially those batch-milking cows in the morning and evening, with those peak loads typically 10 times greater than midday loads,” he explains.
Hourihane notes that standard solar panels have peak production midday “Yes, this energy can be stored in a battery to recycle, to heat water for wash down or to build an ice bank for evening milking to chill the milk, but this is just shifting the energy use. It’s not a perfect match,” he says. “Every unit that can be consumed directly is one that doesn’t have to be purchased from a supplier, and the farmer doesn’t have to pay for battery storage.”
David Foran is one of Hourihane’s agricultural customers. He installed a 27-kW system in 2019 with 30 percent covered by a government grant. In a testimonial, he estimated he recouped his share ($21,800) of the cost in less than 2 years. Initially, he expected a payback in 7 years, but higher-than-expected energy costs reduced the payback period dramatically.
He noted that his system generated 27.5 MWh in 2020, half his total electricity consumption for the year. More importantly, 74 percent of the energy generated was consumed on the farm.
While Sunstream works only in Ireland, Next2Sun has announced a partnership with iSun, a Vermont company. The two plan to install a vertical bifacial solar fence with panels up to 6 1/2 ft. high on 30-ft. spacings on a Vermont vegetable farm early in 2024.
In announcing the new venture, iSun CEO Jeffrey Peck stated, “Thanks to the vertical mounting of the modules and the adaptability of the installation to the needs of the farmer, the valuable land is almost completely preserved for agriculture.”
