Agrivoltaics — co-locating solar arrays with farming operations — is generating enthusiasm among both farmers and clean energy advocates as a way to promote sustainability in agriculture. 

When implemented correctly, agrivoltaics provides a vital dual income stream for farmers — in solar energy generation, but also as a means of providing an optimal growing environment for compatible crops and herds. The added revenue may allow more farmers to retain their land for themselves and future generations. 

While pilot projects around the country are identifying best practices, not all have been successful, and practitioners say that advancing the technology will require an equitable approach that centers farmers’ needs first.

A discussion during the recent Solar Farm Summit in Rosemont, Illinois, directly addressed the issue, featuring a majority-Black panel of practitioners and service providers. Three major themes emerged during the discussion: maximizing compatibility of solar arrays with existing land use, demonstrating the financial benefits of agrivoltaics, and addressing how solar power can help BIPOC farmers hold on to their land.

“I think one thing that, through our work in this technical assistance, has become very, very clear [is] that people don’t just want to build an agrivoltaics project for the sake of building an agrivoltaics project,” said Jordan Macknick of the National Renewable Energy Laboratory (NREL), who also served as moderator for the discussion. “How does agrivoltaics enable you to take that next step and focus on things like succession planning or farmer training?”

Benefits for farmers

Miles Braxton started his company, Okovate Sustainable Energy, to work exclusively on “farmer-focused” solar development.

Braxton said after several years of developing community solar projects, he “really saw the inefficiencies” of taking farmland out of production for solar projects. “That’s a problem that is just going to keep piling on top of itself until it gets to the point where we can’t develop anything.

“We target crop farmers who are growing a very specific suite of crops that we know works well with our design,” Braxton said.

Cetta Barnhart, owner of Seed Time Harvest Farms in Florida, also cultivates her own plot of fruits and vegetables, and cited her background in food and wellness in promoting the compatibility of solar and agriculture to benefit the bottom line for farmers.

“This is more hands-on of what a farmer can really do in their current practices. If they’re raising cattle, there’s a way that they implement solar with that. If they are having bare land, the pollinator is another way that they can benefit from that,” she said. “So how these solar projects are developed and created for real farmers is still a big conversation to be had.“ 

Ena Jones, owner of Roots & Vine Produce and Café, and president of Community Partners for Black Farmers, cited her dual role as a working farmer and an advocate as an advantage in promoting the potential compatibility of agrivoltaics and cultivation — especially for Black farmers.

“We advocate and we also lobby for farmers at the state level for the state of Illinois and the state of Georgia. And I’m here to kind of segue to help farmers understand … how different solar opportunities can help them with production on their farms, and be an asset to the production on their farms. And also, to help solar developers understand farm[ing],” Jones said.

Noting that solar projects can help cut energy costs, Jones said “Energy use is one of the farmer’s [major] expenses outside of diesel, and of course seed. So, if they can reduce that cost dramatically, even by a third, that would impact their bottom line in revenue extensively. It is very important, especially for BIPOC farmers, to be ushered into this technology so that they won’t be left behind in the process.”

Making connections

Agrivoltaics can be a valuable tool to reduce overall costs, expand potential revenue – or both – as a means of promoting optimal use of farmland. A both-and approach can work to address what is often an inherent tension between the best use of large, flat plots of land for large solar arrays – parcels that also frequently comprise some of the richest soil for cultivation. 

For example, the 180 MW Madison Fields project in Ohio represents a test ground for large-scale agrivoltaics – farming on 1,900 acres between the rows of a utility-scale solar array. One of the project’s focuses is determining which crops and herds are the best prospects to coexist with large-scale solar developments.

“People have a lot of questions with regard to energy development going forward in this state … Finding a balance where you can do a number of things on the same ground — in this case energy production as well as agricultural production — is obviously huge,” Dale Arnold, director of energy policy for the Ohio Farm Bureau told the Energy News Network in July.

Macknick highlighted another project where NREL and Clean Energy to Communities (C2C), along with the Black Farmers Collaborative, worked on a proof of concept project which incorporated solar panels on a demonstration farm cultivated by Barnhart that features citrus trees, leafy greens, and other produce.

“I had already looked into doing solar on my property and was just looking at it to have solar as the backup,” Barnhart said. “But when we started talking as a team and then we found out about the agrivoltaics portion [and] how that can be incorporated into farming, it really brought forth a bigger and better opportunity to not just benefit by having it but also sharing that with other farmers,” Barnhart told NREL in 2023.

Mike DellaGala of Solar Collective said taking a farmer-centered approach can also be beneficial to product and service providers.

“I think a lot of the conversation … has been the difference between farmers and developers, and how we are or [are] not communicating and getting projects over the finish line or not. And I think… if you’re farmer-first or farmer-centric, I think that’s the way to success for everybody… allowing [farmers] to dictate a lot of the project details has been really successful for us. And it makes our job easier, frankly,” DellaGala said.

A farmer-centric and collaborative approach is especially vital in ensuring equitable access to the benefits of agrivoltaics for BIPOC farmers, Barnhart said.

“I stand in the gap somewhat between having conversations with [BIPOC] farmers and having conversations with project developers because you need someone in the middle. I’m a community advocate. I hope there are more of us in the room than not. They have to be in place in order to bridge the conversation as to how this really works well in real-life time,” Barnhart said.

Braxton cited the need to rein in the power of utilities, which he says frequently raise roadblocks to community-level projects to protect their own interests. 

“Utilities have too much power. They have too much money to lobby. They don’t want you to sell power back to your community because [of the impact to] their own rates that they can control. So that’s a risk. The root of those problems is that here in the U.S. … we have 50 little countries [states] that make up their own policies and do their own thing… I think there needs to be a policy to incentivize solar to be developed innovatively. I don’t think policy makers at the state level understand the importance of that,” Braxton said.

Jones noted that policy change will likely be driven by farmer demand, which by extension benefits the larger community.

“In my opinion, once the farmers understand [how solar can] help them on their farms, I can’t say this enough, they will force politicians to comply. The money will be there; the funding will be there. But the engagement needs to happen. It desperately needs to happen,” she said.

Land retention for BIPOC farmers

Loss of land –through racism and other factors, has long been a contentious topic among BIPOC farmers – and Black farmers in particular. According to a 2022 study, discriminatory federal policies contributed to Black farmers losing roughly $326 billion worth of acreage during the 20th century. In July, the Biden-Harris administration announced a distribution of $2 billion to thousands of Black and other minority farmers, created through the Inflation Reduction Act as a means to begin to address this inequity.

Agrivoltaics may not intuitively track as a relevant strategy for land retention; but Barnhart touted its value, especially for Black farmers. 

“[Black farmers] have lost a lot of land because we just couldn’t afford to keep it… We didn’t just lose land because it was confiscated… What solar does is add an income stream or a reduction in your expenses so that there’s more you can do on your farm and create an opportunity for the next generation. 

“It gives us a reason to keep the land going, and it gives us, in our community, resiliency we are experiencing through our climate change storms. For the families that can have that piece of land, that builds a resiliency to protect them in their neighborhoods, protect their own backyard, and protect the future generations, give the future generations something they can look forward to that makes sense to them. Then we build into something that takes care of our wealth building opportunities, our succession planning, and our look into the future to make a change,” Barnhart said.

A factory filled with clean white structures produces solar panels, visible in blue at the front of the picture.

DALTON, Ga. — Growing up in Cartersville, Georgia, Lisa Nash saw what happens to communities when factory jobs disappear. It was the 1980s and corporations were offshoring production to reduce costs and raise profits. The jobs that remained in this northwest corner of the state were typically lower-paying ones that didn’t offer the same ladder to the middle class.

“My parents and grandparents were in manufacturing, and they were the ones saying, ​‘Don’t do it,’” Nash recalled.

Nash disregarded their advice, embarking instead on a long career in manufacturing — first in textiles, followed by stints in aviation, automotive, and steel. Now she’s helping to bring higher-tech, higher-paying factory work back to the corridor between Atlanta and Chattanooga. 

Nash is the general manager of the Qcells solar panel factory in Dalton, a town of 34,000 located 50 miles up I-75 from her hometown. It opened in January 2019, after the Trump administration imposed a fresh round of tariffs on Chinese-made panels. The Korean conglomerate Hanwha owns Qcells, and initially planned to hire several hundred people at the site, Nash told me on a recent visit to the factory. By the end of 2019, it employed more than 800. 

Then, in 2020, Georgia helped elect President Joe Biden and sent two Democrats to the Senate, clinching a thin majority. Senators Jon Ossoff and Raphael Warnock got to work crafting detailed policies to promote domestic manufacturing of clean energy technologies, which China had dominated for years; they wanted solar panels and batteries made in America — specifically Georgia — instead of in China, a geopolitical rival.

Those measures made it into the Inflation Reduction Act, which passed in August 2022 — two years ago this week. The legislation created the nation’s first comprehensive policies to support domestic clean energy manufacturing. Qcells broke ground on a second facility in Dalton in February 2023. Completed that August, the expansion added two football fields’ worth of manufacturing space with four new production lines — which produce 1.5 times more solar panels than the original three lines, thanks to technological advances. Now the whole complex employs 2,000 people full time and makes 5.1 gigawatts of solar panels a year, more than any other site in the U.S.

Politicians have been promising for decades to retrain American workers and revive long-lost manufacturing, with little to show for it. Now, though, the U.S. has entered a new era on trade: Leaders of both parties have rejected the long-standing free-trade consensus and its penchant for offshoring jobs. Biden married that reshoring impulse with a desire to boost clean energy production, to both stimulate the economy and fight climate change. 

This grand experiment remains in its infancy, and the success of the clean energy manufacturing revolution is by no means guaranteed. Cheap imports could outcompete even newly subsidized American products. 

And if Republicans win the presidency and retake Congress, they’ve threatened to stop subsidizing low-carbon energy resources and instead double down on fossil fuel production. House Republicans — including Dalton’s representative, Marjorie Taylor Greene — have voted repeatedly and unsuccessfully to repeal the domestic manufacturing incentives in the IRA. (Greene’s press office did not respond to multiple requests for comment.)

“Donald Trump and his Republican allies promised to gut the Inflation Reduction Act if he’s reelected, so there’s a lot at stake here,” Representative Nikema Williams, who leads the Georgia Democrats, told me.

Since the IRA passed, Georgia has received $23 billion in clean energy factory investment, much of it flowing to northwest Georgia. I wanted to see what impact this is having on communities formerly hit hard by industrial decline, so I followed the money trail to Dalton earlier this summer. 

I found a population that seems to like having advanced solar manufacturing in their backyard. Dalton’s solar jobs are boosting wages, invigorating the historic town center, and employing local high school graduates. Those benefits are starting to spread to nearby communities, where new solar factories are springing to life. In November, voters will weigh two very different visions of America’s energy future on the ballot, but Dalton is already reaping the rewards from slotting solar into its storied history of industrial production.

From carpets to solar

Both CSX and Norfolk Southern run Class I rail lines through Dalton, a testament to its industrial legacy, and freight trains bellow day and night.

That legacy harks back to 1900, according to local historians, when Catherine Evans Whitener sold a hand-tufted bedspread from her front porch for $2.50. The cottage industry took off in this land of forested ridges and stream-crossed valleys, and over time, local factories consolidated into global carpeting giants Shaw Industries and Mohawk Industries.

“The carpet industry was born here,” Carl Campbell, executive director of economic development at the Greater Dalton Chamber of Commerce, told me when I visited the Chamber. The New Georgia Encyclopedia states that 80 percent of America’s tufted carpet production happens within 100 miles of Dalton.

The conference room where we spoke sported large-format aerial photographs of the major factories nearby: the largest Shaw site, 650,000 square feet; and the new Engineered Floors colossus, 2.8 million square feet. 

“You feel like there’s enough carpet in that building to cover the whole world,” said Campbell, who grew up in Dalton. 

Dalton employment numbers peaked at 80,200 in 2006, per the Chattanooga Times Free Press. But the Great Recession crushed the homebuilding industry, cratering demand for Dalton’s carpeting products. 

Dalton ​“was a ghost town in 2011, nothing going on because everybody was hurting,” Campbell added. From June 2011 to June 2012, Dalton notched the dubious distinction of most jobs lost of all 372 metro areas surveyed by the Bureau of Labor Statistics. By that point, one-quarter of Dalton’s pre-recession jobs had vanished, and unemployment surged to 12.3 percent. 

Since then, the industry has recovered somewhat. Engineered Floors, Mohawk, and Shaw still dominate local employment, with some 14,000 jobs among them, Campbell said. Those companies have had to adapt to evolving consumer tastes, shifting from wall-to-wall carpets to hardwood and other flooring materials. They’ve also automated aspects of production, reducing the number of workers needed.

In the wake of the Great Recession, local leaders sought to diversify Dalton’s industry. The county acquired an undeveloped lot south of town, and Campbell later pushed to clear and level the site, so it was shovel-ready for some future tenant. When Trump’s solar tariffs kicked in, Campbell’s counterparts at Georgia’s Department of Economic Development sent Qcells his way. 

Qcells showed up in February 2018, looking to spin up its first American solar-panel factory in less than a year. ​“Suddenly, we had exactly what they needed,” Campbell said.

Thus Dalton managed to bring in new industry to balance out its base of carpets and flooring. Qcells originally promised to invest $130 million and hire 525 people within five years, Campbell said. 

“They did it in three months,” he added. ​“In terms of an economic development project, they check all the boxes: Everything they said they would do, they did it faster than they said they would do it.”

Domestic solar manufacturing, by humans and robots

When I asked folks around town what they thought of Qcells, they kept mentioning the dozens of air-conditioning units arrayed on the factory roof, like a field of doghouses, easily visible from I-75. I later learned that Qcells brought in helicopters to install those units, which made for a bit of small-town spectacle. Still, it struck me as a surprising detail to dwell on for a business that somehow turns the sun’s rays into cheap, emissions-free electricity. 

Once I crossed Qcells’ sizzling parking lot and stepped indoors, it started to make sense. Georgia gets hot, and carpet factories get hot, but the vast floors of the twin solar factories are quite literally cool places to work. 

The climate control is not unique to assembling solar panels, but it is required for the sensitive, precisely calibrated product. The air conditioners are but one sign that high-tech manufacturing has arrived, and that it makes for pretty comfortable work.

I met my two tour guides, Wayne Lock and Alan Rodriguez, in the factory lobby, and they quickly confirmed the physical appeal of Qcells jobs. Lock, now a quality engineer at Qcells, previously worked in carpet manufacturing; he had to wear special heat-resistant gear to handle carpeting materials that would otherwise deliver third-degree burns. Rodriguez, an engineering supervisor at Qcells, used to apply the coating material underneath carpets.

“You’re sandwiched between the steamer and the oven, so it gets quite hot,” Rodriguez told me. Attending to those machines exposed him to temperatures that could exceed 100 degrees Fahrenheit.

Even more than Qcells’ air conditioning, though, people I spoke to kept bringing up the pay.

By offering more for zero-skill, entry-level positions than the other factories in town, Qcells started attracting workers and pushed up wages across Dalton, Campbell said: ​“Competition brings everybody, so everybody’s had to kind of equalize to keep employees.” 

Now Qcells hourly wages for non-experienced hires start at $17.50 to $22 — that amounts to $36,400 to $45,760 a year for full-time work. Workers with experience in robotics and manufacturing can take home much more than that. Employees can raise their pay through a variety of on-the-job training, most of which involves handling and troubleshooting the in-house fleet of robots.

Lock, Rodriguez, and I walked into the newest factory, past meeting rooms with names like Naboo and Mandalore, Star Wars locales where quirky robots coexist with all manner of creatures. As we strolled across the floor, squat wheeled autonomous vehicles rolled past us down pathways marked by tape on the smooth floor, ferrying bales of materials or hauling out hulking boxes of finished panels.

“We try to stay out of their way, and if we don’t, they yell at us,” said Lock. ​“It’s fun.”

As we stood talking, I noticed that one such robo-buggy was waiting for us to move. Barely discernible over the background drone of machines, a female voice intoned, ​“Robot is moving. Please look out.” When humans hold up more time-sensitive deliveries, Lock explained, the voice switches to male and gets louder. 

Other robots remain fixed in place, carrying out repetitive precision tasks. I stared, mesmerized, at one machine that split wafer-thin silicon cells in half, first scoring them with a laser, then slicing them with a concentrated jet of water. A taller machine grabbed nearly 8-foot metal frames and sliced them through the air like a master swordsman in a Kurosawa film, to slot them around glassed-in silicon panels. 

Throughout the process, cameras scan cells and use artificial intelligence to shunt defective items off the line for manual correction. 

In the 2019-era factory next door, humans carry out many of these tasks. Lock, though, didn’t see the robots as competitors — he said they were taking on more physically demanding jobs so the humans could step into higher-skilled roles tending to robots.

“The ergonomics are better for you,” he said, and the new lines are more productive. 

Hiring local, spending local

When Qcells was first staffing up, it relied on Quick Start, a Georgia state program that funds worker training for new factories before they open — a major draw for executives deciding where to locate their factories.

Qcells still recruits to meet ongoing staffing needs, and it has been paying special attention to high schoolers who are graduating and looking for employment. Nash speaks passionately about Qcells’ recruitment efforts; she’s seen the civic fallout from decades when local families encouraged kids to avoid manufacturing.

“Small communities cannot thrive with kids graduating and leaving those communities to live elsewhere, to get high-paying technical jobs,” Nash said. ​“That’s what’s happening across the country. Bringing manufacturing back, and bringing highly automated manufacturing, is offering job opportunities where now these students are staying here.”

Some 56 percent of Dalton-area students enroll in postsecondary education within 16 months of graduating high school, said Stephani Womack, director of education and workforce development for the Greater Dalton Chamber of Commerce. For the remainder, the chamber wants to make sure family-supporting jobs are available.

For two weeks in June, Womack helped run Project Purpose, a crash course in how to start and navigate careers that pay living wages. Recent high school graduates prepped for interviews, shopped for professional clothes, and toured housing options and downtown hotspots — the kinds of places they could frequent once they join the workforce. 

But the centerpiece of the program amounted to professional speed dating, as Dalton’s major employers offered tours and entry-level jobs. Last year, Dalton’s first time running Project Purpose, seven young adults completed the program, and Qcells hired one of them. This time, 18 finished, and Qcells hired 12 of them to start on July 1.

“Next year, we hope to double that, or more,” Nash said. 

Several participants came in knowing about Qcells, betting that the intensive crash course would increase their odds of landing good roles there, Womack told me over a table at Garmony House, a downtown coffee shop that draws lines for its statuesque strawberry cupcakes and coffee-glazed cinnamon rolls.

“Qcells is providing a diverse set of options for our students who need to go to work but want to stay in our community,” Womack said. ​“They see a climate-controlled facility with entry-level opportunities — that’s exciting for them. … Manufacturing isn’t what it used to be.”

For younger people to stay in town and build a life, Dalton needs more housing, and now it’s getting its first large apartment complex in over two decades, Campbell said. In total, 900 apartment units are slated to come online from last August through this November — not enough to catch up on a long-running housing deficit, but a step in the right direction.

That renewed real estate activity is reflected in downtown Dalton’s bustling core. 

Locals pack the booths at the Oakwood Cafe, perhaps the only place in America that sells a platter of egg, sausage, toast, and grits for just $3.65. Multiple microbreweries beckon, as does a plush cocktail bar, the Gallant Goat, which stocks fresh mint by the fistful to garnish its drinks. Down the road, diners can sample ceviche of shrimp shipped in from coastal Mexico, succulent chicken wings, and high-end Southern cuisine. 

This spring, the plush Carpentry Hotel opened across from the Oakwood Cafe, decked out with vibrant textile art to commemorate the town’s carpeting heritage.

“That’s been big for us, getting that hotel in downtown. That’s indicative of a robust local economy that people are coming to participate in,” local real estate agent Beau Patton told me as the late afternoon sun streamed into the Gallant Goat. Patton works with Qcells employees who want to buy homes in the area. He sees the factory’s decision to locate there as ​“very mutually beneficial” for Qcells and Whitfield County: ​“What you hope is Whitfield County grows with it, and it grows with Whitfield County.” 

From Dalton to towns across Georgia

Dalton got in early on the national clean-energy factory revival, and has already seen its solar factory push up wages, enable high school graduates to stay and start careers, and inject money into a reinvigorated downtown. Many more communities in Georgia are following close behind with their own cleantech factories, seeking a similar economic jolt.

“There is a palpable and intense sense of excitement across the state about how these manufacturing and infrastructure policies are supercharging Georgia’s economic development,” said Senator Jon Ossoff, the Georgia Democrat who authored the IRA manufacturing incentives that Qcells is tapping into. ​“And I would add, it’s not just the primary industrial facilities; it’s all of the secondary and tertiary suppliers and vendors and service companies and the financial services firms needed to support them.”

Qcells is building an even bigger factory compound down in Cartersville, which won a conditional $1.45 billion loan guarantee from the Department of Energy on August 8. This facility will take advantage of Inflation Reduction Act tax credits to onshore more steps of the solar supply chain: slicing silicon wafers, carving them into solar cells, and assembling finished modules with even newer robots than the ones I saw in Dalton. Until now, those high-value precursors to solar panels were shipped in from overseas. Workers in Dalton complete just the last step: assembling modules. Cartersville promises to bring the dream of American-made solar a bit closer to reality.

To achieve that dream, the industry has a few other challenges to confront. For one, 97 percent of the glass that encloses solar panels comes from China. Besides the geopolitical implications of that dependence, glass is so fragile and heavy that its shipping costs make domestic production enticing both economically and environmentally. 

“We need domestic glass to have an efficient supply chain,” said Suvi Sharma, founder and CEO of solar recycling startup Solarcycle. His company is breaking ground on a combination solar-panel recycling facility and solar-glass factory in Cedartown, some 70 miles southwest of Dalton. Sharma expects to invest $344 million in the community and hire 600 full-time employees.

Compared with Dalton and Cartersville, ​“Cedartown is more off the beaten path — this would be the first large-scale factory going up there,” said Sharma. After years in which the population declined and young people looked elsewhere for jobs, ​“this enables them to keep people and bring in more people. There’s a cascading impact.”

Solarcycle will use its rail spur to ship in low-iron silica from a mine in Georgia, plus soda ash and limestone. Over time, it will supplement those raw ingredients with increasing amounts of glass the company will pull from decommissioned solar panels, including those made by Qcells. The goal is to produce enough glass for 5 gigawatts of panels per year; Solarcycle will ship the glass to nearby customers. At that point, workers in northwest Georgia will have a hand in all the major steps of solar-module production except the processing of raw polysilicon. Hanwha recently became the largest shareholder in REC Silicon to secure access to domestic polysilicon from the Pacific Northwest. 

Georgia also nabbed a hefty chunk of the electric-vehicle factory buildout catalyzed by IRA incentives. Hyundai is dropping nearly $1 billion on its ​“Metaplant” near the deepwater port of Savannah and building an adjacent $4.3 billion battery plant with LG. Kia erected a new EV9 SUV manufacturing line at its plant in West Point, about halfway down Georgia’s border with Alabama. The first EV9 rolled off the line in June — less than two years after the IRA was signed into law.

Dalton, then, is a leading indicator of the industrial invigoration that clean energy factories are bringing to cities and towns across Georgia. People broadly appreciate it — if not for the role in combating climate change or countering China’s industrial might, then for high starting wages, comfortable working conditions, and opportunities for advancement. 

But for this nascent factory boom to endure, the policies that triggered it need to stay in effect. The people of Georgia played a decisive role in spurring this manufacturing revival; this November, they’ll have an outsize role in deciding if it continues.

Darryl Moton is ready to “get on a roof.”

The 25-year-old Chicago resident is among the latest graduates of an intensive 13-week solar training course that’s helping to connect employers with job candidates from underrepresented backgrounds.

Moton was referred by another job readiness program meant to keep youth away from gun violence. He “never knew about solar” before but now sees himself owning a solar company and using the proceeds to fund his music and clothing design endeavors.

He and others interviewed for jobs with a dozen employers assembled at a church on Chicago’s West Side on August 1 as part of the fourth training cohort for the 548 Foundation, which is partnering with Illinois Gov. J.B. Pritzker on a recently-announced $30 million initiative to create 1,000 solar jobs in Chicago’s South and West side neighborhoods.   

The 548 Foundation is part of 548 Enterprise, a suite of renewable energy and affordable housing development projects, launched in 2019 and named after the public housing unit where co-founder A.J. Patton grew up. 

The idea is to help keep housing affordable by using solar to lower energy bills, while training people left out of the traditional energy economy to supply that solar. 

“When you invest in a community, the biggest question is who benefits, who gets the jobs?” asked Patton, during the job fair. “This is as good as it gets,” he added, about the recent state investment. “We just have to keep advocating for quality policy.” 

Employers at the job fair said such training programs are crucial for them to find workers in Illinois, where robust solar incentives are attracting many out-of-state companies eager to hire and hit the ground. Mike Huneke, energy operations manager for Minnesota-based Knobelsdorff said he has hired 18 employees from previous 548 cohorts, and he expected to make about six job offers after the recent interviews. 

“Illinois is on fire,” said Huneke. “We’re not from Illinois, so finding this new talent pipeline is what we need. We have a ton of projects coming up.” 

Lisa Cotton, 30, has dreamed of being an electrician since she was a kid. She had received two job offers at the August 1 fair before the group even broke for lunch. 

“A lot of times you go through a training program, get a certificate, and that’s the end of it,” said Jacqueline Williams of the Restoring Sovereignty Project, a partner which administers the wraparound services for the training program. 

The 548 program makes sure to connect graduates with employers, and only companies with specific openings to fill are invited to the job fair. 548 and its partners also stay in contact with graduates and employers to make sure the placement is successful. 

“We have a post-grad program where they can call us any time, and an alumni fund. If an employer says, ‘This guy can’t come to work because his radiator is busted,’ we’ll take care of that,” said Williams.

Achieving equity   

After Illinois passed an ambitious clean energy law in 2017, multiple solar training programs were launched in keeping with the law’s equity provisions. But employers and advocates were frustrated by a seeming disconnect in which many trainees never got solar jobs, and employers weren’t sure how to find the workers. 

Since then, the state has passed another clean energy law – the 2021 Climate & Equitable Jobs Act, with even more ambitious equity mandates; and non-profit organizations have developed and honed more advanced workforce training programs. To access incentives under the law, employers need to hire a percent of equity-eligible applicants that rises to 30% by 2030. The program prioritizes people impacted by the criminal justice system, alumni of the foster care system, and people who live in equity-designated communities. 

548 affiliates help employers navigate the paperwork and requirements involved in the equity incentives. Several employers at the job fair said this is a plus, but noted that regardless of equity, they are desperate for the type of highly-trained, enthusiastic candidates coming out of the 548 program. 

“This is a great way to bridge what the state is trying to do with its clean energy goals, and connecting under-represented people with these opportunities,” said Annette Poulimenos, talent acquisition manager of Terrasmart, a major utility-scale solar provider. “We came here ready to hire, and I think we’re going to walk away with some new talent.”   

Member organizations of the Chicago Coalition for Intercommunalism do outreach to recruit most of the training program participants. 

Nicholas Brock found out about the training thanks to a staffer at one of these organizations who noticed his professional attitude and punctuality as he walked by every morning to a different workforce program. 

“Whatever I do, nine times out of 10, I’m the first one to get there, before the managers,” said Brock, 20. “He noticed that and asked me, ‘Have you ever heard about solar panels?’” 

Brock knew little about solar at that point, but now he aims to be a solar project manager. 

“I’m so glad I came here,” he said. “They bring out the best in you.” 

Full service 

Wraparound, holistic services are key to the program’s success. During the training and for a year afterwards, trainees and alumni can apply for financial help or other types of assistance. 

“There are so many barriers, it might be child care or your car is impounded,” said Williams. “We might be writing a letter to a judge asking to ‘please take him off house arrest so he can work.’ It’s intensive case management, navigating the bureaucratic anomalies that arise when you’re system-impacted.”

Moises Vega III, 26 – who always wanted to work in renewables because “it’s literally the future” – noted that his car battery died during the training program, and he was provided funds to get his vehicle working again. 

While ample support is available, the program itself is rigorous and demanding. Classes meet from 9 a.m. to 3 p.m. each day, and trainees are required to check their phones at the door and be fully focused, notes instructor and 548 workforce strategies director Michael Thomas. During the hands-on boot camp week, the day starts at 6 a.m. 

“That’s when the trades start,” noted Thomas. “You need to figure out how that works, how will you get child care at 5:30 a.m.?” 

Sixty-one trainees started in the first three cohorts, and 46 graduated, the first group in July 2023. The fourth cohort started with 25, and as of the job fair, 18 were on track to graduate. Eighty-five percent of graduates from the first three cohorts are currently working in the field, according to 548. 

“Even though I wish the graduation rate were higher, the people who commit to it, stay with it,” said Kynnée Golder, CEO of Global HR Business Solutions, which has an oversight role for the 548 Foundation. “It’s monumental, it’s life-changing for a lot of people.”

Comprehensive curriculum 

The curriculum starts with life skills, including interpersonal relationships, resume-building, financial planning and more. Each day begins with a spiritual reflection. 

The students learn about electricity and energy, and soon move into specific instruction on solar installation and operation. Rooms at St. Agatha’s church served as labs, where students connected wires, built converters and eventually mounted solar panels on a demonstration pitched, shingled roof. 

Terrance Hanson, 40, credited Thomas as “the best instructor ever.” 

“I’m not a young kid, my brain is no longer a sponge,” Hanson said. “He made sure I got it all. Now I feel like I know so much, I’m confident and prepared to get out and show what I can do.” 

He added that people in disinvested neighborhoods have ample untapped potential to be part of the clean energy workforce.  

“You see a lot of basketball players in my community because there are a lot of basketball hoops,” he said. “If there were golf courses in the hood, you would see more golfers. It’s about opportunities. And this was the most amazing and empowering thing I’ve ever been through.” 

Jack Ailey co-founded Ailey Solar in 2012, making it the oldest still-operating residential installer in Illinois, by his calculations. He noted that there can be high turnover among installers, and intensive training and preparation is key. 

“You’re out there in the sun, the cold, it’s heavy physical labor, wrestling 40-pound panels up to the roof,” he said. “You have to know what you’re getting into.” 

“Some training programs vary in quality,” Ailey added, but he was impressed by the candidates at the 548 job fair. 

Trainees test for and receive multiple certifications, including the OSHA 30 for quality assurance, and the NCCER and NABCEP for construction and solar professionals, respectively. The program is also a pre-apprenticeship qualifier, allowing graduates to move on to paid, long-term apprenticeships with unions representing carpenters, electricians, plumbers and laborers – the gateway to a lucrative and stable career in the trades. 

Thomas noted that most trade unions still don’t have a major focus on solar. 

“We’re ahead of the unions, and our graduates bring real value to them, and to the companies,” he said. “The students might know more than a company’s foreman knows. It’s a win-win situation. Solar is a nascent industry, there’s so much opportunity in this space.” 

When Tredgett Page, 38, connected with 548, his auto detailing work and other odd jobs were not going well. He had always loved science and been curious about photosynthesis and the sun’s power. 

“I had been in the streets before, and I was leaning back toward that, but God brought me here,” he said. “Now I have the confidence, I know what I’m talking about, I know about megawatts and kilowatts, net metering, grid-connected, pretty much anything about solar.” 

He sees metaphorical significance in his new trade: “Energy is life, and it teaches you balance, it’s all about negative and positive ions.” He feels like “the sky is the limit” after the training. 

“I have so much skill that they gave me, now I’m hungry to use it,” he said. “I’m a little nervous, but optimistic, excited, very exuberant!”

Saxon Metzger stands in a field of wildflowers with the Chicago skyline in the distant background.

Growing up in Southern California, Saxon Metzger and his brother Ayda Donne — now 29 and 26 — didn’t think much about their Indigenous heritage in Oklahoma. Their great-grandmother’s family fled the reservation after her aunt saw her mother murdered during the Osage Reign of Terror, when locals brutally attacked tribal members over oil resources, as the brothers learned while researching the family history.

In the past decade, the brothers began exploring this history, including the fossil-fuel linked violence and exploitation recently showcased in the film “Killers of the Flower Moon.” Today, the Osage Nation is home to the country’s highest concentration of abandoned, uncapped oil and gas wells, which continue to leak methane and other dangerous pollutants. 

Now, Metzger and Donne are seeking to connect with and give back to the Osage Nation and other tribal communities by making sure clean energy does not leave its own legacy of abandonment or disinvestment. 

Eighth Generation Consulting, an organization Metzger founded, aims to provide solar decommissioning workforce training and project management, as well as promote solar installation. 

“Tribal nations, along with many other historically disenfranchised communities, are justifiably skeptical of development that doesn’t fully acknowledge its potential shortcomings, having been bearing the brunt of fossil fuels,” Metzger said. 

Osage Nation Chief Geoffrey Standing Bear has officially pledged support for the brothers’ vision. In March, Eighth Generation won a U.S. Department of Energy Community Energy Innovation concept phase prize, meaning a $100,000 grant, mentorship and the chance for more DOE funding. Metzger was also recently awarded a Grid Alternatives Tribal Energy Innovators Fellowship, which comes with $50,000 and mentorship, and he is a finalist for MIT’s Solve Global Challenges Indigenous Communities Fellowship program. 

Family roots 

Metzger studied economics at Southern Illinois University and the University of Utah, then returned to Southern Illinois to help facilitate the deployment of solar in the largely rural, lower-income region. 

He was program director for the nonprofit Solarize Southern Illinois, then worked as a project developer for StraightUp Solar, a residential and commercial solar installer focused on underserved areas in Illinois and Missouri. Metzger got an MBA with an emphasis in sustainability from Wilmington University, then worked for a decommissioning company in California. 

Striking out on his own, he co-founded a company called Polaris Ecosystems that does solar decommissioning project management and consulting. Polaris is under contract to support commercial and utility-scale repowering in California and Texas, Metzger said, declining to give more details because of confidentiality clauses in the contracts. 

The company collaborated with a Georgia solar waste management company called Green Clean Solar, whose founder, Emilie Oxel O’Leary, said she plans to partner with Polaris on more contracts. Her company has found ways to reuse solar packaging and components – for example, using thousands of cardboard boxes from solar delivery as mulch for a tree nursery in Hawaii, where landfill space is especially scarce. 

“Saxon and I find these solutions together. We find sustainability. We bring circularity to our conversations,” she said. “Very few [companies] do what we do. These billion-dollar companies have never stopped and thought about this.” 

Metzger now leads Eighth Generation and Polaris from Chicago, while also teaching a sustainable business class at Wilmington University. 

Donne is in charge of grant-writing for Eighth Generation, while pursuing his doctorate in English literature at New York University, with a focus on Indigenous literature and environmental justice. Donne also collaborates with NYU professor and toxicologist Judith Zelikoff, doing blood and urine testing and health workshops with the Ramapough Lenape Nation in New Jersey, who face serious health threats from a former Ford Motor Company illegal dump that is now a Superfund site. Donne hopes to further intertwine the humanities and STEM sides of academia in pursuit of environmental and energy justice for tribes.  

“My family is very scarred by what happened during the reign of terror. They tried to run” from that legacy, said Donne, who also works as chief librarian at the International Center for MultiGenerational Legacies of Trauma. “But repressing things like that rarely works, rarely protects you for very long. I like to think that Saxon and my work is kind of a departure from that history of denying our identity and running from the pain that’s in our family.”

On visits to the Osage Nation, the brothers say they’ve recognized the cultural as well as economic importance that fossil fuels still hold for the tribe. They strive to acknowledge and respect this dynamic while promoting clean energy. The tribe currently has no large-scale solar on its land, and this year a federal judge ruled that a controversial wind farm must be removed because it failed to get proper permits a decade ago. The tribe has long opposed the wind farm, which was built on sacred land.    

“We’re trying to plug into the existing things that they’re doing, and not show up and say, ‘Hey, we know what the solution is,’” said Metzger. “This is my tribe, these are my folks, my culture, my people. But I am approaching it with the understanding that to a certain degree, I’m also an outsider from a market that they don’t have access to.” 

Metzger added that when he first visited the Osage Nation, “I didn’t see a single solar panel, on the entirety of the reservation. I looked for it. I was shocked. It was one of the few places I’ve ever seen that there were no Trump flags, and there were no solar panels.” 

Metzger said that it is still likely a long road to installing solar on the reservation, but he’s been encouraged by tribal leaders, and received a letter of support in July from Osage Chief Standing Bear. 

A growing need 

More than half of states have decommissioning policies that require financial assurances be put up in advance, according to a 2023 year-end report by the North Carolina Clean Energy Technology Center and DSIRE. Nineteen states have no state-level decommissioning policies at all, the report shows, including Wisconsin, Iowa, Arizona and Pennsylvania.

“When it comes to assurance policies, you want to make sure landowners won’t be stuck with the bill at the end of the day, a dine-and-dash situation,” said Justin Lindemann, a co-author of the report and policy analyst at North Carolina State University’s Clean Energy Technology Center. “In most states, you have to have these finances in place well before the project decommissions.” 

Solar project contracts and permits typically include a decommissioning estimate. In states with financial assurance requirements, developers are usually required to put up incremental amounts of financing over time for decommissioning, so that there is not a major financial burden tacked on to the project’s startup cost. 

Metzger said that in his experience, estimates can be unrealistically low, a situation that in the near-term can benefit everyone, as the project cost appears lower. 

“The reality is that our industry doesn’t really want to have that conversation” about decommissioning costs and logistics, “because a developer, if they included the full cost of decommissioning, would not sell as many projects,” Metzger said. “No one really wants to hear that the project is going to cost more.” 

Lindemann said he hasn’t seen major problems with low-balled estimates, but there still have been relatively few large-scale decommissions. State laws and policies can try to ensure that estimates are accurate and large enough financial assurances are available. For example, Ohio requires that estimates be revised periodically, and if the estimate has increased, the required bond must be increased too.  

Ideological opponents of solar have stoked fears about solar panels filling up landfills and presenting hazardous waste. Those concerns are often exaggerated, as solar panels are made up primarily of steel and glass and the toxic compounds in the cells present relatively little risk, experts say. Even as solar farms expand exponentially, solar waste will still be much smaller than other waste streams, like construction debris and municipal garbage. 

Nonetheless, responsible and smooth decommissioning is crucial for the industry to thrive, experts agree. 

“We live in a social media environment where bad stories, singular bad examples do spread,” said Lindemann. “We need to make sure that relationships don’t get strained because of a lack of direction regarding deconstruction and decommission. Do people involved in or impacted by a project understand what’s in front of them 20 to 25 years down the line? That level of trust and transparency can be built, and comprehensive directives from states and other entities provide the first step.” 

In 2023, almost 33 GW of solar were installed nationwide, and solar deployment is only expected to keep growing. 

“In order to handle that, it’s important to make sure state and local governments have the right rules in place to handle mass decommissioning,” said Lindemann.  

Many challenges 

Metzger notes there are many costs and logistics to decommissioning that can be easy to overlook: the need to remove fences and drive over fields to haul panels off, lodging for workers, renting equipment like pile drivers, dealing with buried electrical conduit or other hazards. 

“If you look at a site, there isn’t one solution,” Metzger said. “Say you have 20,000 panels, that’s a bunch of metal. How heavy is that? What kind of tractor trailers are you going to need to pull it? What about the labor, how many 40-pound panels can someone lift in an hour?” 

Metzger and Donne are developing a decommissioning workforce training curriculum, and hope to eventually train Osage tribal members and others in various aspects of decommissioning work and project management.  

“We’re thinking about what this is going to look like for our tribe in 100 years,” said Donne. “Are these structural resources available when Saxon and I are long gone?”

That perspective is what inspired the name Eighth Generation, Metzger explains. 

“It’s often cited as an indigenous principle to think of an action through seven generations of impact, and that phrase always reminded me that some problems just won’t show up until the eighth generation,” he said. 

“And it feels like that is what’s happening here, as we’re staring down millions of panels annually needing decommissioning. It’s all solvable problems to an industry that genuinely is making the world a better place. We need to follow through on the promise we made as an industry to be meaningfully different than previous energy systems, and taking care of our legacy assets is a necessary component of that.”

Editor’s note: An earlier version of this story described Eighth Generation Consulting as a nonprofit; it is a for-profit entity that is exploring nonprofit status.

Studies will explore whether multi-use farming mixes with utility-scale solar, focusing on both scientific and practical questions.

Research underway at a Madison County solar farm promises to shed light on how well multi-use farming can work at a large scale. The answers will help shape best practices for future projects, while addressing some concerns raised in ongoing debates over siting large solar projects in rural farm areas.

Spread across more than 1,900 acres, the 180 MW Madison Fields project will be one of North America’s largest test grounds for research into agrivoltaics — essentially farming between the rows on photovoltaic solar projects.

As farmers seek to lease land for solar arrays to diversify their incomes, the practice could help them maximize their income and fend off opposition from critics concerned that solar development will take prime farmland out of production.

Some farmers have also said the revenue from clean energy can help keep their farms operating amid pressure from housing developers. A recent report from the American Farmland Trust says Ohio could lose more than 518,000 acres of farmland to urban sprawl by 2040.

That number dwarfs the roughly 95,000 acres for certified and other projects noted on the Ohio Power Siting Board’s most recent solar case status map

Yet solar projects generally deal with big chunks of land at once, while urban sprawl happens bit by bit over time, said Dale Arnold, director of energy policy for the Ohio Farm Bureau. Helping people understand and appreciate that is “absolutely huge,” he said.

Savion, a Shell subsidiary, developed the Madison County project, and it began commercial operation on July 11 with Amazon as the long-term buyer for its energy. Yet work began much earlier this year to set up the site for research by Ohio State University scientists, Savion’s Between the Rows subsidiary, and others.

“People have a lot of questions with regard to energy development going forward in this state,” particularly when it comes to taking land out of use for agricultural production, Arnold said.

Yet today’s industry continues to shift away from coal to a diversified portfolio of natural gas, nuclear, hydropower, wind energy, solar energy and other types of generation. Forecasts also show there will be growing demand for electricity by mid-century, he said.

“Finding a balance where you can do a number of things on the same ground — in this case energy production as well as agricultural production — is obviously huge,” Arnold said. If agrivoltaics is to become more than a buzzword, though, both farmers and solar project developers need to work out best practices.

One big issue is what crops can work well for large-scale utility projects. Compared to most solar farms projects in Eastern and Piedmont states, utility-scale solar projects in Ohio and other Midwestern states can spread across 1,000 acres or more, Arnold said.

“You hear a lot about produce and specialty crops,” for example, said Sarah Moser, Savion’s director of farm operations and agrivoltaics. But raising them is “hard to do on 1,000 acres.”

Hay, you!

Moser and Ohio State University researchers think forage crops like alfalfa and hay hold promise. Operations can be scaled up for large areas, said Eric Romich, an Ohio State University Extension field specialist for energy development. And the crops wouldn’t grow too tall amid the panels.

“We also wanted something that we felt had the potential to be economical,” Romich said.

Two 2023 reports by Ohio State University Extension researchers found raising hay and alfalfa between rows of solar panels was feasible and that the harvest’s nutritive value was good. But that small-scale work at the Pigtail Farms site in Van Wert County used data from only a few test plots and controls, which is an important limitation, Romich said.

Work at Madison Fields will now test whether similar results can be achieved at large scale. Part of a $1.6 million grant from the Department of Energy will help pay for that work over the course of four years.

Other research will test how well plants do in sun versus shade, Romich said. That matters because some portion of the land among solar panels will always be shaded.

Researchers planted the crops on test fields and control areas this spring, with an eye toward starting to collect data next year. “Forages are quite temperamental in terms of trying to get them established,” said Braden Campbell, an animal scientist at Ohio State University who is also working on the project. The team has found compacted soil around the solar panels, “but we are relieved to see that the seeds that we put into the ground are growing,” he said.

Moser plans to work with other crops, too. Soybeans are one example. They were already used as a cover crop before alfalfa and hay were planted. Soybeans can also work into a crop rotation when forage crops need to be replanted every few years.

“The market is there for it, and it does well” as a hardy crop which can also loosen soil and restore nutrients to it, Moser said, adding that local communities have expressed interest in the crop as well.

Send in the sheep

Other work at Madison Fields will explore complementary grazing. The goal is to harvest the forage crops as efficiently as possible. But there will still be a need for vegetation control under and around panels and other infrastructure, said Campbell. So, after harvesting, sheep will go to work.

“To me, that’s three commodities that we can get off one unit of land,” Campbell said: Solar panels will produce electricity. Hay and alfalfa growing will provide a crop. And the land will help support sheep, which in turn can produce meat, milk and fiber.

Other solar farms already use or plan to use sheep for vegetation control. But “there is a big difference” between using sheep to keep plants under control and relying on that for their nutrition, Campbell said.

Studies will need to test the health of sheep that do complementary grazing, compared to other sheep. Other questions include finding optimal grazing rates of sheep per acre, as well as other logistics. But first, the forage needs to establish good roots so it can withstand the pressure of grazing.

Tractors and more

A third bucket of research questions under the Department of Energy grant will focus on farm equipment. Tractors and other farm vehicles need to fit between the rows with their attachments. There’s been a trend in the agricultural sector toward wider equipment, which can cover more ground quickly but may not fit between rows of solar panels, Moser said.

“But a lot of farmers still have smaller equipment,” Moser continued, because some parcels aren’t appropriate for wider machinery. Maneuvering 15-foot-wide equipment works fairly well, and 17-foot and even 20-foot widths can still work. 

“I could get my 20-foot drill in there,” Moser said. “I just have to be careful.”

Arnold speculated that some companies may develop special equipment whose attachments can fit under solar panel rows more easily. Other possibilities could include raising panels or even feathering them when agricultural equipment is in use, he suggested.

Farm equipment doesn’t just need to go down an alley between two rows of solar panels. It will also have to turn around at the end to go down another one, Arnold said. So, there needs to be an adequate turning radius, without cables blocking farm vehicles’ paths. Poles, stands, and other equipment also can’t block the path of the farm equipment, he said.

The research can help guide the design of future solar projects to be “hay-ready” sites, Romich suggested. At the same time, agricultural operations shouldn’t jeopardize the safe and efficient operation of a solar facility. “It’s an operating power plant,” Romich said.

Arnold has additional questions about infrastructure needs: What facilities will be necessary to dry, bale and store forage? What facilities will other crops need? And how will they be trucked out to markets?

Likewise, what equipment and facilities will be needed for any sheep kept on site?  That includes paddock fencing, water, and so forth. And where will their caretaker live? 

“You’re going to have to have people there full-time,” Arnold said.

Precision agriculture

The Ohio State researchers, Moser, and others also wonder how well precision agriculture can work with solar farms. The term refers to methods that rely on technology and data to guide farmers’ work. The range of technologies includes remote sensing of field conditions with drones, in-ground sensors, automated weeders and more.

The big question is which precision agriculture technologies can work well for crops planted between rows of solar panels as they generate electricity.

It’s unclear what any of the studies will show until data has been collected and analyzed, Romich said. By the end, he feels the work will provide a better understanding of what will or won’t work.

Economics questions about business models, contractual arrangements and more also must eventually be worked out, Arnold said. At the end of the day, farmers will need to make a profit if agriculture is to successfully blend with solar projects.

“The possibilities are limitless, really,” when it comes to business arrangements, Moser said. “My motto is always, ‘farmers figure it out.’ And if we work with them, we’ll figure…out how to do this with best practices.”
