When Byron Kominek returned house after the Peace Corps and later working as a diplomat in Africa, his household’s 24-acre farm close to Boulder, Colo., was struggling to show a revenue.
“Our farm has mainly been hay producing for fifty years,” Kominek mentioned, on a latest chilly morning, the solar illuminating a dusting of snow on the foothills to his West. “This is a big change on one of our three pastures.”
That large change is definitely an eye fixed opener: 3,200 solar panels mounted on posts eight ft excessive above what was an alfalfa area on this patch of rolling farmland on the doorstep of the Rocky Mountains.
Getting thus far, a neighborhood solar backyard that sells 1.2 megawatts of energy again into the native grid wasn’t straightforward, even in a progressive county like his that wished to broaden renewable power. When Kominek approached Boulder County regulators about placing up solar panels, they initially advised him no, his land was designated as historic farmland.
“They said, land’s for farming, so go farm it,” Kominek says. “I said, well, we weren’t making any money, you all want to be 100% renewable at some point so how about we work together and sort this out.”
They finally did, with assist from researchers at close by Colorado State University and the National Renewable Energy Lab, which had been finding out flip all that in any other case unused land beneath solar panels into a place to develop meals.
With shut to 2 billion {dollars} dedicated to renewable energy within the newly handed infrastructure invoice, the solar business is poised for a win. But there have lengthy been some tensions between renewable builders and a few farmers. According to NREL, upwards of two million acres of American farmland might be transformed to solar within the subsequent decade.
But what if it did not need to be an both or proposition? What if solar panels and farming might literally co-exist, if not even assist each other.
That was what piqued Kominek’s curiosity, particularly with so many household farms barely hanging on in a world of company consolidation and so many older farmers nearing retirement.
For about 50 years, Byron Kominek’s household grew alfalfa and raised some cows on their farm close to Boulder, Colo.

Last yr, Boulder County up to date its land use code. And quickly after Kominek put in the solar panels on one in all this pastures. They’re spaced far sufficient other than each other so he might drive his tractor between them.
Still, when it got here time to plant earlier this yr, Kominek was initially skeptical.
But he quickly found that the shade from the towering panels above the soil truly helped the crops thrive. That intermittent shade additionally meant a lot much less evaporation of coveted irrigation water. And in flip the evaporation truly helped preserve the sun-baked solar panels cooler, making them extra environment friendly.
By summer season, Kominek was a believer.
Walking the intricately lined rows of veggies beneath the panels, he beams declaring the place the peppers, tomatoes, squash, pumpkins, lettuces, beets, turnips, carrots had been all lately harvested. The farm is nonetheless bursting with chard and kale even in November.
“Oh yeah, kale never dies,” Kominek says, chuckling.
Kominek’s farm, rebranded as Jack’s Solar Garden (Jack is his grandfather’s identify), is a part of a burgeoning business often called agrivoltaics. It’s a comparatively new area of analysis and Kominek’s farm is one in all solely about a dozen within the United States recognized to be experimenting with it.
But agrivoltaics is drawing explicit curiosity within the West, now within the grips of a 22 yr megadrought.
“Around the western US, water is the reason to go to war,” says Greg Barron-Gafford, a University of Arizona professor who is thought of one of many nation’s foremost specialists within the area.
“Water is the reason we have to have real big arguments about where we’re going to get our food from in the future,” he says.
Barron-Gafford’s analysis within the Arizona desert confirmed some crops grown beneath solar panels wanted 50% much less water. He and different scientists have their eyes on the infrastructure invoice and are pushing to get among the estimated $300 million included in it for brand spanking new solar initiatives to go towards agrivoltaics.
“If you really want to build infrastructure in a way that is not going to compete with food and could actually take advantage of our dwindling resources in terms of water in a really efficient way, this is something to look at,” Barron-Gafford says.
Researchers say there must be monetary incentives for household farmers so as to add solar to their portfolio, if solar gardens like Byron Kominek’s are actually going to take off and change into mainstream.
In Kominek’s case, he literally wager the farm to be able to finance the roughly $2 million solar arrays.
“We had to put up our farm as collateral as well as the solar array as collateral to the bank,” he says. “If this doesn’t work, we lose the farm.”
But farming is all about taking up danger and debt, he says. And early on anyway, it is wanting like his wager might repay.
“That humming [you hear] is the inverters making us money,” he says, pointing towards an electrical converter field mounted close to a row of kale. A collection of wires carry the facility out to the county freeway and onto the native Xcel Energy grid.
The inverters right here generate sufficient energy for 300 properties to make use of in a yr. Kominek hopes to quickly develop sufficient meals beneath the panels to possibly feed as many native households.
