Agrivoltaics, which combines solar energy generation with agricultural production, represents a cutting-edge solution to land use challenges. The University of Hawaiʻi’s Office of Sustainability and College of Engineering participated in a tour of the Hawaiʻi Agriculture Research Center (HARC) Agrisolar project in November. The event highlighted the intersection of renewable energy and agriculture, offering students a firsthand look at an innovative approach to sustainable land use.
The HARC Agrisolar project, established in collaboration with AES Corporation, Longroad Energy and Clearway Energy Group, spans a 230-acre solar farm in Mililani. Underneath the panels, researchers have successfully cultivated crops such as lettuce, strawberries, radish and poha berries since the project’s inception in June 2022.
“We learned and witnessed how growing agriculture under solar produces higher yields of both food and energy,” said Miles Topping, director of the UH Office of Sustainability.
The dual-use system enhances sustainability by creating microclimates that reduce heat stress, conserve water and support biodiversity.
Hands-on experience for students
For engineering students, the tour offered a chance to connect classroom learning with real-world applications. Participants observed thriving crops beneath solar panels and engaged with researchers to understand the challenges and successes of agrivoltaics.
“It was really cool seeing land being used for both agriculture and clean energy production,” said Nicholas Atkins, a UH engineering student. “I am excited to see where their research will take sustainability on Oʻahu.”
The HARC Agrisolar project showcases dual-use systems that address land scarcity, enhance food security, and advance renewable energy while prioritizing Indigenous and locally significant crops. Learn more about the project at Agrisolar Clearinghouse.
