Sunzaun CEO Interview | Clean Power Hour
Sunzaun CEO Interview | Clean Power Hour 336 333 Sunzaun

“Everybody was just asking for incentives, […] but I’m like, […] you should stop talking about incentives. How about the idea that if you don’t do agrivoltaics, you won’t have the biomass yield you need in the future — period. Because the climate is changing.”  — Helge Biernath, CEO of Sunzaun


This powerful call to action served as an opener on a recent episode of The Clean Power Hour, setting the tone for the types of conversations that are reshaping how we think about the future of agriculture. 

As the clean energy transition accelerates –  largely driven by climate change, energy security, and economic opportunities – stakeholders are increasingly turning to farmland. Not to replace crops, but to use solar infrastructure as a complementary partner to agriculture. In this episode, host Tim Montague is joined by Helge Biernath of Sunzaun and Sunstall, and Ian Skor, CEO of Sandbox Solar, to dive into the growing world of vertical agrivoltaics. 

The Roots of Agrivoltaic Innovation

Sandbox Solar, founded over a decade ago, began testing crop performance under solar arrays back in 2018. What they found was that certain crops actually performed better under semi-transparent solar panels compared to traditional full-sun conditions. 

“[Too much] sun can be stressful for some plants,” Montague elaborated during the podcast. “We’re learning a lot — and there’s still so much to learn.” 

This duality — where crops grow within the sheltered space between solar arrays — may play a critical role in the future of sustainable agriculture. This is especially true for regions that face water scarcity and extreme heat events.

Meanwhile, Sunzaun, which grew out of the solar installation company Sunstall Inc., peered over at European trends. CEO Biernath observed the emergence of vertical racking systems that allowed crops and solar to share the same land with minimal footprint loss. With few domestic options for such systems, Biernath saw an opportunity to bring this innovation stateside.

Most recently, the two companies teamed up to launch an agrivoltaics testing site at Colorado State University. This site was designed to demonstrate real-world applications of agrivoltaics using vertically-aligned modules. With adequate spacing between rows, tractors seed and harvest crops with ease, proving that solar and agriculture don’t have to compete. 

Field crops like corn are being evaluated for their growth under panels, while researchers also monitor how the crops, in turn, affect solar output. The project is already collecting valuable data that could help inform and educate the community, as well as pave the way for the expansion of agrivoltaics nationwide.

The agrivoltaics research site at Colorado State University. In 2024, researchers planted corn within rows of bifacial vertical arrays to monitor crop growth, PV energy output, and a variety of other metrics such as soil moisture and temperature. Sunzaun’s flexible racking system enables panels to be raised by several feet if necessary — an adaptive feature to accommodate taller crops or future design needs.

Europe and Asia: A Glimpse Into the Future

Montague emphasized that Northern Europe and parts of Asia are nearly a decade ahead of the U.S. when it comes to agrivoltaic deployment. Why? Biernath believes space constraints have driven these regions to integrate solar directly into the built and agricultural environment.

“In the U.S., we have lots of land,” Biernath states. The issues lie between where that energy is needed and where it is being generated. Bringing solar photovoltaics to agricultural land found near urban hubs could reduce the need to curtail energy, a challenge recently spotlighted in parts of California. 

As the population expands, so will the pressure to balance land use among conservation, development, agriculture and energy production. Pairing solar with farming, as already seen in parts of Europe and Asia, is critical for sustaining projected growths. 

The Challenge: Awareness and Policy

If agrivoltaics offers so many benefits, why aren’t we seeing it everywhere?

According to the guests, the biggest hurdles might be awareness. Farmers may not be aware of the sheer benefits of incorporating vertical solar on agricultural land. Additionally, policy frameworks may not yet be set up to support dual-use systems, but the movement is growing. Vertical solar offers a low-footprint, high-impact solution that aligns with fostering agricultural productivity, climate mitigation and farmer resilience.

Key Takeaways

  • Vertical agrivoltaics allows solar energy and agriculture to share the land, increasing efficiency and resilience.
  • European and Asian countries are leading in adoption, offering insights for U.S. researchers, developers and the agricultural community.
  • Real-world test sites, like the one at Colorado State University, are proving that tractors, crops, and solar panels can work together.
  • Barriers remain, including public awareness and permitting processes — but growing data and interest are breaking new ground.

Art to Inspire: Visions for the Next Generations at Hamilton Elementary School
Art to Inspire: Visions for the Next Generations at Hamilton Elementary School 2560 1226 Sunzaun

In the heart of Novato’s Hamilton community, a vibrant mural sits above a set of windows, now brightening the library walls at Hamilton Elementary School. This piece does more than decorate a wall; it reveals a story of progress, sustainability, and connection to the natural environment and to others. Painted by local artist Linsey Vera, known as “Miss Vera”, the mural took one month to complete and was the largest and most detailed piece she had completed to date. The piece was spearheaded by school librarian Beatriz Garcia De Gallegos and commissioned by Sunstall Inc. to promote education and environmental stewardship by planting seeds of inspiration in the minds of the young students.

“I want to have something in the library that can inspire the kids [firstly] to take care of our Mother Earth, and secondly, to dream big and become interested in science and engineering, (…) and especially encourage girls to be part of this field”, Garcia De Gallegos shared her motivations behind the project. She worked closely with Miss Vera to be sure she captured this idea while incorporating all of the important elements. 

At first glance, the mural is a colorful celebration of nature and children. Upon a closer look, deeper messages unfold. “From what I see, it’s all about inclusion and equality between everyone, like, see how they are doing different tasks, working together?” eighth grader, Jesus, explains his interpretation of the mural as he nods to the painted figures.

In the foreground, three smiling children stand close together, each symbolizing a different facet of interests and cultural background. One cradles a bundle of freshly harvested vegetables, representing local food systems. Another wears a shirt with the text Solar Power with a beaming sun, referencing renewable energy. The third supports a stack of books about plants, clean energy, biology, and the history of California and the Miwok tribe, highlighting the importance of knowledge and cultural roots. Behind them are two more children with hard hats, huddling near solar panels and reviewing documents. They look like “construction workers”, Samantha, a third grader, describes.


Set against a lush green backdrop, the background features rolling farmland, grazing animals and Californian flora coexisting with solar panels and wind turbines. Samatha again, a lover of animals, expressed that she “was amazed” when she first saw the mural. 

Fourth grader, Saul, said the mural is “really nice because it shows the green stuff, solar power, and farms. You can use solar panels to power [the farm] and shield the animals [from the sun].” “I feel like if there is a story [to the mural], it is Protect Nature because solar power is helping the environment by using electricity, so it’s teaching people to help the environment more.” 

Solar array systems and farmlands are elements of a real-world concept called agrivoltaics, where renewable energy and agriculture come together on shared land in a mutually beneficial relationship. Examples of the dual use of agrivoltaic systems with photovoltaics (solar energy) include crop production, livestock grazing and pollinator habitats. These types of arrangements are particularly compelling because solar infrastructure provides microclimates to the surrounding environment. The shade generated from the panels allows for increased moisture retention for plants and serves as a reprieve for livestock during hot summer days. In turn, plants cool the solar panels, increasing their efficiency, and therefore, increasing their energy production. This mural shows that it is entirely possible to incorporate renewable energy and food production, alongside a healthy thriving ecosystem. 

The attention to detail is what makes this art piece special. Each element is thoughtfully placed to spark joy, curiosity and empowerment. Beatriz Garcia De Gallegos hopes people have a connection with the mural as much as she does, “I had this idea for years and thanks to Helge, it became possible.” Helge Biernath, President and CEO of Sunstall Inc., explains his reason for funding the mural, “[We wanted it to] serve as inspiration for children to pursue knowledge while promoting social responsibility and climate awareness.” By blending natural landscapes with clean energy technology, it serves as a daily reminder that sustainable progress is possible and comes from collaboration across interests, fields and backgrounds. A green future includes interdisciplinary cohesion.

On sharing her initial thoughts about her involvement in the mural, Vera, the artist, was “happy this mural was going to be focused around the kids’ futures in renewable energy jobs. Anything that gets them thinking, whilst also enjoying the art is something I’m super excited to work on”.

Garcia De Gallegos, Vera and Biernath have plans to meet with the students in the fall for an in-depth talk and project relating the themes present in the mural. “Hamilton is really a special place and I hope to work more with the kids in the future” Vera stated.

Whether it’s a child who dreams of working with plants, animals, people, or in renewable energy, this mural invites every student to see themselves as part of an environmental stewardship narrative. So now, as students walk through their library this fall, surrounded by stories on the shelves and on the wall, the hope is that this mural will empower students. “What kind of future will you help build?”

When it Comes to Land Use, Solar Power Outshines Corn
When it Comes to Land Use, Solar Power Outshines Corn 618 626 Sunzaun

A recent study published in Proceedings of the National Academy of Sciences and featured in Anthropocene Magazine delivers a compelling message: when it comes to using land to produce energy, solar power significantly outperforms corn-based bioenergy. Researchers find that it requires over 30 hectares of cornfields to generate the same amount of energy, in the form of ethanol, that just one hectare of photovoltaic (PV) panels can provide¹.

This has major implications for land use, especially as development faces growing pressure from population growth and environmental degradation. Unlike corn production, solar energy requires no fertilizer, herbicides, or irrigation—resources that are increasingly scarce or harmful when overused. The shift to solar not only increases energy yield per acre, but could free up land for other uses.

The benefits of replacing corn with solar power extend well beyond land efficiency. Corn, while a crucial crop for human consumption and livestock feed, does little to support biodiversity, especially when grown in large monocultures. Corn is self-pollinating and is not considered a primary food source of pollinators. Additionally, the heavy use of pesticides in cornfields inadvertently kills off bees, butterflies, and other important insects. This lack of ecological refuge contributes to the decline of pollinators—many of which are already at risk of extinction from habitat loss and climate change². 

Biodiversity Benefits From Solar; Dual Land Use

In response, stakeholders such as research institutions, private companies, and governmental organizations are promoting dual land use systems that combine pollinator-friendly habitats and solar arrays. By integrating native vegetation, these initiatives create new habitats for at-risk species, helping restore biodiversity³. 

This is where vertical PV systems such as Sunzaun offer real, cutting-edge solutions. These upright solar structures allow sunlight to reach the ground between rows, making it possible for native vegetation and pollinator-friendly plants to thrive among them⁴. Additionally, cash crops such as strawberries, buckwheat, and flowering herbs have been found to perform well under solar arrays while supporting pollinators and soil health, providing additional income opportunities. These systems enable landowners to replace monoculture with multi-functional, living landscapes; a combination of clean energy production with ecological benefits.

A Sustainable Approach: The Future of Energy

Corn remains an essential crop for food and feed, thus its role in agriculture is not under debate. However, using corn to produce fuel is resource-intensive, particularly when better alternatives like solar power exist. By reducing our reliance on corn for energy and reserving farmland for food, we can strike a future-forward balance between energy needs and ecological wellbeing. 

Research demonstrates that PV infrastructure can enhance, rather than displace, natural systems. As the climate crisis intensifies and agricultural pressures mount, the smartest path forward is one that balances our energy demands with sustainability. Vertical PV systems promote a more regenerative, biodiverse, and resilient energy future.

Sunzaun on Track: Vertical Bifacial Solar PV for Railways
Sunzaun on Track: Vertical Bifacial Solar PV for Railways 1024 1024 Sunzaun

As railroads intersect countries and connect cities, they offer a unique opportunity for energy generation. Vertical bifacial solar systems are well-suited to turn these corridors into high-efficiency, low-footprint power sources—without interfering with train operations or requiring additional land.

Why Railways Are Ideal for Vertical Bifacial PV Infrastructure

Railway networks offer miles of underutilized space that is already cleared, maintained, and graded. Traditional horizontal solar systems struggle to fit into these narrow strips. That’s where Sunzaun’s vertical design excels:

  • Small Footprint: Vertical PV (photovoltaic) systems require only a narrow strip of land, making them ideal for trackside positioning in right-of-way areas or even between dual-track corridors (CleanTechnica, 2025).
  • Reduced Afternoon Glare: Unlike tilted PV panels, Sunzaun’s vertical installation reduces glare risks, enhancing railway safety compliance.
  • Preexisting Infrastructure: Panels can be mounted along existing fences, barriers, or access roads, reducing construction effort and regulatory friction.
  • Dual-Sided Generation: Panels absorb direct and reflected light from both sides, increasing energy capture and generation.
  • Morning and Evening Peaks: Energy generation aligns with early and late demand periods—often matching train station energy usage (Overeasy.no, 2024).

Integration with Railway Power Systems

  • DC Coupling Options: Vertical solar systems can feed into traction substations, minimizing energy losses from AC-DC conversion (Electric & Hybrid Rail Technology, 2024).
  • Smart Grid Compatibility: Integration with inverters enables future compatibility with train station microgrids and auxiliary systems.
  • Removable and Modular: Sunzaun structures can be installed with temporary or quick-release mounts to allow access for track maintenance, drawing on concepts similar to the Sun-Ways system in Switzerland (Euronews, 2024).

Additional Benefits for Rail Operators

  • Security Fencing + Energy: Sunzaun infrastructure can double as secure fencing, used to protect both railroad operations and the public from hazards, reducing material and installation costs.
  • Noise Mitigation Potential: Mounted along sound barriers, they attenuate noise pollution, benefiting wildlife and neighboring communities, increasing community acceptance.
  • Low Maintenance: Vertical alignment limits soiling from dust and debris stirred up by passing trains (SolarWA.org).

Vertical Bifacial PV can unlock huge potentials for decentralized, cost-effective renewable energy generation without competing for land or disrupting preexisting infrastructure. Railways have the opportunity to not only serve as transportation arteries, but climate-neutral power corridors.

From Runways to Renewables: Vertical Solar Power at US Airports
From Runways to Renewables: Vertical Solar Power at US Airports 512 288 Sunzaun

As the world intensifies efforts to reduce carbon emissions and embrace renewable energy, the role of airports in this transition is often overlooked. Traditionally seen as major energy consumers due to the constant demands of air traffic and facilities, airports are now becoming key players in sustainable energy generation. A particularly innovative approach gaining traction is the use of vertical solar farms. This article explores how vertical photovoltaic (PV) systems can revolutionize energy production at airports and contribute to a greener aviation industry.

Airports as Ideal Locations for Solar Installations

Airports represent some of the most promising locations for large-scale solar energy generation. With large expanses of unused or underutilized land around runways and taxiways, airports can install solar farms without impacting air traffic. In fact, airports are already being recognized for their potential as renewable energy hubs. Around 20% of public airports in the U.S. have adopted some form of solar power, including rooftop and ground-mounted systems [https://solartribune.com/solar-power-takes-off-at-u-s-airports/].

Vertical solar systems like this installation by Sunzaun offer a variety of innovative applications, e.g. on farms or airports

How Vertical Solar Farms Benefit Airports

Energy Savings and Reducing Airports’ Carbon Footprints

Vertical solar farms can help airports significantly reduce energy costs by generating clean, renewable electricity on-site. This cuts down on utility bills and also reduces the airport’s overall carbon emissions, contributing to a greener, more sustainable operation.

Opportunities for Additional Revenue Streams

In addition to energy savings, airports with large solar installations have the potential to sell excess power back to the grid, creating additional revenue streams. This economic benefit adds to the appeal of solar farms for airport operators.

Impact on Operational Efficiency and Public Image

Adopting solar energy can enhance an airport’s operational efficiency by providing a stable, renewable power source. Furthermore, it can improve the airport’s public image, positioning it as a leader in sustainability and innovation, which is increasingly important in the eyes of environmentally conscious travelers.

Challenges of Installing Vertical Solar Farms Near Airports

Potential Concerns About Aviation Safety, Including Glare and Air Traffic Disruption

One of the key concerns about solar farms near airports is the potential for glare, which could impair pilots’ vision during takeoff or landing. However, vertical solar farms tend to produce less glare than traditional horizontal installations, as they are designed to absorb sunlight from different angles. Strategic placement and the use of anti-glare technologies can further mitigate these risks [https://www.airsight.de/projects/item/solar-farms-at-airports-a-key-to-the-transition-to-renewable-energy-at-aerodromes/].

Engineering and Regulatory Challenges Specific to Airport Environments

Solar farms at airports face unique regulatory and engineering challenges, particularly regarding aviation safety standards. Developers must ensure that solar installations do not interfere with radar or communication systems, and they must comply with strict Federal Aviation Administration (FAA) regulations.

Solutions: Anti-Glare Technology, Strategic Placement

To address these challenges, developers are employing advanced anti-glare technology and carefully planning the placement of vertical panels. By positioning panels at the correct angles and distances from runways, airports can enjoy the benefits of solar energy without compromising safety.

Future Prospects: Expanding Solar Farms on U.S. Airports

Case Studies of U.S. Airports with Solar Installations

Several U.S. airports have already embraced solar energy. Indianapolis International Airport is home to one of the largest airport-based solar farms in the world, generating enough power to supply 10,000 homes annually. Denver International Airport has also made strides in solar energy, with four separate solar arrays that collectively generate over 10 MW of power [https://solartribune.com/solar-power-takes-off-at-u-s-airports/].

Highlight Key Projects, Such as the Frankfurt Airport Vertical PV Installation

Globally, airports are setting the stage for the adoption of vertical solar farms. Frankfurt Airport, for example, has recently launched the world’s largest vertical PV installation, covering 30.8 hectares and generating 17.4 MW of power [https://www.linkedin.com/pulse/worlds-largest-vertical-pv-system-welserprofilenorthamerica-jatvf]. This project serves as a model for U.S. airports looking to adopt similar systems.

How U.S. Airports Can Replicate These Successful Projects

U.S. airports can follow in the footsteps of international leaders like Frankfurt by investing in vertical solar technology, adapting it to local regulations, and addressing safety concerns through engineering solutions. Collaboration between solar developers and airport operators will be key to realizing these projects.

Conclusion

Vertical solar farms have the potential to transform energy production at airports. As technology advances and policy support for renewable energy grows, vertical PV installations can become a cornerstone of sustainability initiatives at airports across the U.S. With their ability to optimize space, reduce energy costs, and lower carbon emissions, vertical solar farms offer a bright future for the aviation industry.

Why Vertical Bifacial Panels Along Canals Could Be a Game-Changer
Why Vertical Bifacial Panels Along Canals Could Be a Game-Changer 1021 571 Sunzaun

Solar energy systems are evolving—not just in what they’re made of but also in how and where they’re installed. One innovative approach gaining attention is using vertical bifacial solar panels on the sides of irrigation canals.

These panels collect sunlight from the front and back, allowing them to harness more energy throughout the day. But beyond the tech itself, it’s the placement strategy that makes this idea stand out.

Why Go Vertical — Along a Canal?

Traditional solar arrays are typically installed at a tilt (e.g., 20°) facing south. That works well, but it requires open land, is prone to dust accumulation, and creates steep seasonal production curves with big summer peaks and winter valleys.

In contrast, vertical bifacial systems can:

  • Collect light on both sides, especially when ground or nearby surfaces reflect sunlight.
  • It stays much cleaner in dusty environments—vertical orientation reduces soiling by up to 95% compared to tilted panels¹.
  • Perform better in winter months, leading to a flatter seasonal production profile — important for grid stability².

When placed along a single canal bank, these panels avoid the need for complex mounting over the water. This is a major advantage in regions where canal access is only available from one side or where installing overhead structures is too costly or logistically impractical.

What About the Energy Output?

Modeling shows that a south-facing vertical bifacial array, without any reflector, can deliver about 87% of the annual energy of a standard south-facing 20° tilted monofacial array — but with superior performance in the non-summer months².

Adding a simple reflective tarp across the canal (or part of it) can increase that output by another 19%–24 %. If a hybrid reflector is used — combining a durable base with a shiny aluminized Mylar top layer — the boost can reach 41%–44%³.

In addition, this setup helps to reduce evaporation from the canal by about 61%, thanks to shading and reduced wind-driven losses — a valuable bonus in water-stressed regions⁴.

To put that into perspective: saving 610,000 gallons per year (from a canal segment losing 1 million gallons annually) is equivalent to the annual water use of 9 to 22 Californians, depending on regional consumption habits⁵.

In agriculture, this amount of water could irrigate around 0.37 acres of rice or 0.63 acres of field crops, showing how solar canals help conserve both water and energy⁶.

Now scale that up: California has approximately 4,000 miles (6,400 km) of irrigation canals⁷. If similar systems were deployed along the canal network, they could save up to 63 billion gallons of water per year⁸ — enough to supply more than 2 million people annually or to irrigate over 50,000 acres of farmland⁸.


Where and When Does It Make Sense?

This design is particularly well-suited to:

  • North-south oriented canals less than 17 feet (5.2 m) wide⁴
  • Dusty, high-soiling environments (e.g., California’s Central Valley)¹
  • Locations where land availability is limited
  • Projects where only one canal bank is accessible

In these scenarios, vertical systems can be cost-competitive or even cheaper than traditional canopy systems – especially as structural and installation costs (e.g., steel, concrete) continue to rise. Modeling suggests that vertical systems could remain economically viable even on canals up to 25 feet wide, depending on material and labor costs⁴.

Conclusion

Vertical bifacial systems – like SunZaun – offer a promising alternative to conventional solar designs, especially for dual-use applications like canals. They’re more space-efficient, resilient to dust, and better balanced across seasons. And when paired with a smart reflector design, they can rival — or even surpass — traditional systems in total output.

Rethinking orientation and placement may be just as important as improving the panels themselves.

 Addressing Heat Stress in Berry Crops with Innovative Shade Solutions
 Addressing Heat Stress in Berry Crops with Innovative Shade Solutions 6400 3600 Sunzaun

Heat stress is becoming a concern in berry farming, with rising temperatures putting crops at risk. While moderate heat stress levels can benefit berries by extending the growing season and enhancing flavor profiles. Excessive heat can have detrimental effects. The same heat that may initially boost plant health and fruit development can, when it becomes too intense, turn against the crop. Excessive heat disrupts plant growth, compromises productivity, and throws off the delicate hormone balance within the plant. This often results in problems such as sunscald and fruit cracking.

To mitigate these issues, farmers are exploring innovative solutions, such as providing shade during the hottest parts of the day. By offering protection from the intense afternoon sun while allowing the morning and evening sunlight to continue ripening the berries, the growth cycle can be optimized. This strategy not only prevents overheating but also promotes healthy berry development.

One such solution is the Sunzaun system, which provides a practical method of shading crops during peak heat hours. By using vertical solar panels, the Sunzaun system creates shade that helps prevent excessive heat from reaching the berries. This system allows farmers to protect their crops from the harmful effects of heat stress, all while enabling them to harness solar energy.

The integration of solar energy through agrovoltaic systems offers an additional benefit to farmers. Not only does the shade from solar panels protect the crops, but the system also generates electricity. This allows farmers to offset the cost of the solar installation by using the energy produced on-site or selling it back to the grid. In this way, the combination of agriculture and solar energy production increases the overall value of the farm, providing both environmental and economic benefits.

By embracing these sustainable solutions, berry farmers can enhance productivity and reduce the risks associated with extreme heat. The Sunzaun system and agrovoltaic technology provide a promising pathway to adapting to climate change and improving crop resilience, ultimately leading to healthier, more robust berry production.

 Exciting Launch of Agrovoltaics at Rutgers: The Cow PV Initiative
 Exciting Launch of Agrovoltaics at Rutgers: The Cow PV Initiative 996 751 Sunzaun

On September 30th, Rutgers University celebrated a significant milestone with the ribbon-cutting ceremony for its groundbreaking Sunzaun vertical photovoltaic (PV) system at the Cook Campus in New Jersey. This innovative agrovoltaic project is prominently visible from Highway 1. It serves as a striking example of how sustainable agriculture and renewable energy can harmoniously coexist.

The Cow PV Initiative uniquely integrates vertical solar panels with cattle grazing. Creating a dual-use environment that benefits both energy production and agricultural practices. This pioneering approach not only enhances land efficiency but also exemplifies the potential for synergy between renewable energy and livestock management.

As part of a comprehensive study, researchers have established three experimental blocks. One at a standard height and two at varying heights. To investigate how these configurations influence cow grazing patterns and the quality of the surrounding grass. By analyzing the interplay between solar panel height and pasture health, the team aims to uncover the optimal setup for maximizing both energy output and the nutritional quality of the pasture.

The primary objective of this research is to understand how cattle graze in relation to the solar infrastructure. Insights gained from this study could lead to innovative practices that enhance productivity for farmers. All the while advancing renewable energy initiatives.

We extend our heartfelt gratitude to the many supporters who joined us in celebrating this important milestone for sustainability. A special thanks goes to Executive Dean Laura Lawson, Rutgers Senior Vice Provost of Research Denise Hein, New Jersey Senator Bob Smith, New Jersey Secretary of Agriculture Ed Wengryn, New Jersey Board of Public Utilities Commissioner Marian Abdou, U.S. Department of Energy Solar Energy Technologies Office Director Becca Jones-Albertus, and New Jersey Assemblywoman Andrea Katz. Their commitment to advancing renewable energy solutions has been instrumental in bringing this project to fruition.

This initiative not only marks a significant step forward in agrovoltaic research but also highlights Rutgers’ dedication to fostering innovative solutions for a sustainable future. We invite you to stay tuned as we continue to explore the potential of agrovoltaics. It has a transformative impact on both farming and energy production. Together, we can build a greener tomorrow!
