Agrivoltaics: A Win-Win for Farmworkers and Crops

Putting solar panels above agricultural crops may do more than produce food and clean energy on the same land: It can also significantly augment quality of life for farmworkers, according to new research to be presented at AGU's 2025 Annual Meeting in New Orleans. Worker-reported benefits include shelter from the sun, cooler drinking water and reduced fatigue, while physical measurements indicate the panels can help farms avoid conditions conducive to dangerous heat stress. "In a lot of [food] sustainability conversations, we're thinking about resource use and not about farmworkers and their bodies," said Talitha Neesham-McTiernan, a human-environment researcher at the University of Arizona who led the research. She will present herworkon 15 December atAGU25, joining more than 20,000 scientists discussing the latest Earth and space science research. Hybrid solar-food fields, better known as "agrivoltaics" systems, typically involve solar panels mounted at or above head height, spaced among crops to allow sunlight to pass through the gaps between. In addition to making efficient use of land, these systems can benefit crops by reducing both sun damage and water lost to evaporation—and even by trapping some heat near the ground during colder months, Neesham-McTiernan said. In her four years of fieldwork on farms like these, often during brutal Arizona summers, Neesham-McTiernan noticed a pattern: Researchers and farmworkers alike would strategically plan to work in the panels' shade during the hottest hours.
