Maine Blueberry Farm Pioneers Agrivoltaic Project

Blueberries are big business in Maine, contributing upwards of $250 million to the state economy each year. That’s why a new partnership among blueberry growers, researchers, and the solar industry to harness the power of sun caught our attention.

“The potential for this project to pave the way in providing farmers with alternative income streams while still producing the iconic Maine wild blueberry is exciting, and we’re thrilled to be a part of it,” said Dr. Lily Calderwood, University of Maine Extension Wild Blueberry Specialist.

Currently, 38 U.S. blueberry farms contribute more than $4.7 billion to the economy annually. In Maine, blueberries contribute to $250 million to the economy.

“We’re pleased to be working alongside the University of Maine as well as industry leaders like Navisun and BlueWave Solar on this innovative project that will help promote the growth of the agrivoltaics market as well as support local farmers,” said Chris Ichter, director of business development at CS Energy.

Research indicates that the co-location of solar arrays with crops may reduce water usage by 30% and increase crop production by 70%. With an already large contribution to Maine’s economy, blueberry farmers, as well as others, may benefit greatly from combining crops and solar.

The pilot program outlined what are known as “dual-use challenges.” This study will attempt to understand some of those concerns by using half of the 10-acre project as a control group to study “optimal solar construction techniques.”

“CS Energy, Navisun and BlueWave Solar have all been incredibly engaged and cooperative throughout the whole process, which is crucial, as this is not only the first project of its kind for the University of Maine, but also for the entire state,” said Dr. Lily Calderwood, University of Maine Extension Wild Blueberry Specialist.

The research findings of this program will not only help future developers plan and execute effective dual-use systems, but ultimately will help support local farmers through advancing clean energy and discovering new income streams.

The Maces Pond Agrivoltaics Pilot Project in Rockport, Maine is the result of a collaboration between Bluewave Solar, Navisun LLC, and CS Energy, and the University of Maine. Read more about this partnership, here.

NPR Visits AgriSolar ‘Garden’ in Colorado

NPR recently visited Jack’s Solar Garden, a Colorado farm among about a dozen in the U.S. investing in the colocation of solar energy and farmland.

When Byron Kominek returned home after the Peace Corps and later working as a diplomat in Africa, his family’s 24-acre farm near Boulder, Colo., was struggling to turn a profit.

“Our farm has mainly been hay producing for fifty years,” Kominek said, on a recent chilly morning, the sun illuminating a dusting of snow on the foothills to his West. “This is a big change on one of our three pastures.”

That big change is certainly an eye opener: 3,200 solar panels mounted on posts eight feet high above what used to be an alfalfa field on this patch of rolling farmland at the doorstep of the Rocky Mountains. – NPR

Now, Kominek sells renewable energy back into the local power grid.

As much of the western U.S. has been plagued by a 22-year megadrought, NPR reports that agrisolar is gaining momentum.

“Around the western US, water is the reason to go to war,” says Greg Barron-Gafford, a University of Arizona professor who is considered one of the country’s foremost experts in the field.

“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 research in the Arizona desert showed some crops grown underneath solar panels needed 50% less water. He and other scientists have their eyes on the infrastructure bill and are pushing to get some of the estimated $300 million included in it for new solar projects to go toward 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. – NPR

Greg Barron-Gafford is among more than 30 partners of NCAT’s AgriSolar Clearinghouse.

NCAT Launches Nation’s First AgriSolar Clearinghouse

In less than a decade, solar installations are expected to cover more than 3 million acres of the United States, creating a big opportunity to pair solar with agricultural land to produce food, conserve ecosystems, create renewable energy, increase pollinator habitat, and maximize farm revenue.

The National Center for Appropriate Technology, a nonprofit focused on sustainable energy and agriculture solutions, has launched the nation’s first AgriSolar Clearinghouse to connect farmers, ranchers, land managers, solar developers, and researchers with trusted, practical information to increase the co-location of solar and agriculture.

“There are tremendous benefits of pairing solar and agriculture,” NCAT Energy Programs Director Stacie Peterson, PhD said. “As America’s appetite for sustainably grown products and renewable energy continues to increase, agrisolar has the potential to provide both resources. AgriSolar is a win-win.”  

NCAT’s AgriSolar Clearinghouse features a library of peer-reviewed information, a media hub featuring videos, podcasts, and relevant news, and a user forum to connect people interested in agrisolar development in real-time.

“The AgriSolar Clearinghouse will present a platform open to all Americans for sharing the nationwide efforts in agricultural integration at solar facilities,” said American Solar Grazing Association Executive Director Lexie Hain. “The exciting thing for us at ASGA is that the AgriSolar Clearinghouse will amplify a thoughtful and trusted approach to expanding America’s efforts in solar and agricultural land use.”

The project’s diverse group of more than 30 partners and stakeholders representing private business, renewable energy, sustainable agriculture, national energy laboratories, the Smithsonian, and leading universities will be a key ingredient in supporting the expansion of agrisolar developments across the country.

NCAT’s AgriSolar Clearinghouse is funded by a three-year, $2.03 million cooperative agreement with the U.S. Department of Energy’s Solar Energy Technologies Office within the Office of Energy Efficiency and Renewable Energy. The Solar Energy Technologies Office supports early-stage research and development to improve the affordability, reliability, and domestic benefit of solar technologies on the grid.

“NCAT and our partners are well positioned to help solar developers and farmers connect to make the most out of co-locating solar arrays and agricultural land,” NCAT Executive Director Steve Thompson said. “For 45 years, NCAT has been a trusted broker of practical information to advance locally-grown and sustainable agriculture and energy solutions.”

The AP Reports on the Benefits of AgriSolar Development

The Associated Press is reporting on the benefits of agrisolar development, that is, the co-location of solar panels on appropriate farm land.

“There’s lots of spaces where solar could be integrated with really innovative uses of land,” said Brendan O’Neill, a University of Michigan environmental scientist who’s monitoring how planting at a new 1,752-panel facility in Cadillac, Michigan, stores carbon.

Elsewhere, solar installations host sheep that reduce need for mowing. And researchers are experimenting with crop growing beneath solar panels, while examining other potential upsides: preventing soil erosion, and conserving and cleansing water.

The Associated Press

As the AP reports, the U.S. Department of Energy is searching for the best agrisolar ideas in a project it has called InSPIRE.

The U.S. has about 2,500 solar operations on the electric grid, most generating one to five megawatts, according to the Energy Information Administration. A five-megawatt facility needs around 40 acres (16 hectares). While some occupy former industrial sites, larger installations often take space once used for row crops.

Depending on how quickly the nation switches to renewable electricity, up to 10 million acres (4 million hectares) could be needed for solar by 2050 — more than the combined area of Massachusetts and New Jersey, an analysis by Argonne found. Solar developers and researchers hope projects with multiple land uses will ease pushback from rural residents who don’t want farmland taken out of production or consider solar panels a blight.

“We need healthy agricultural communities, but we also need renewable energy,” said Jordan Macknick, the renewable energy lab’s lead analyst for InSPIRE.
