CASE STUDY
Iowa State University Agrivoltaics
Horticulture and agriculture students will plant crops to study how they perform under solar arrays of various heights and configurations. Engineering students will review solar production data to see how various crop plantings impact solar production.
The research project received a four-year $1.8 million grant from the U.S. Department of Energy via a program called Foundational Agrivoltaic Research for Megawatt Scale (FARMS). ISU was one of only six recipients of the $8 million dollar program. The research team is led by Ajay Nair, Associate Professor of Horticulture; Matt O’Neal Professor in Plant Pathology, Entomology and Microbiology; and Anne Kimber, Director of the Electric Power Research Center.
Researchers plan to explore which crops thrive in a modified solar microclimate. They plan to plant vegetables, fruits, and pollinator habitat. They also intend to study how solar site maintenance impacts cultivation.
