A groundbreaking study from Iowa State University (ISU) suggests that crops, particularly vegetables, can thrive under solar panels, with some even growing better than those in full sunlight. The research, conducted at a 10-acre Alliant Energy solar site near Ames, examines the potential of agrivoltaics—using land for both agriculture and solar energy production.
Initial findings indicate that the partial shade provided by the solar panels benefits heat and drought-sensitive vegetables, offering a promising solution for land use as solar energy demand grows. Although it’s early to determine if fruits like strawberries and grapes will see higher yields, the study shows that vegetables can be grown commercially on solar farms.
ISU’s ongoing research expands this year to include crops like tomatoes, pest management trials, and additional pollinator habitats. The university aims to improve crop yields and economic viability for farmers while supporting Iowa’s clean energy transition. Free public tours are being held to share these promising findings.
