During a 2023 field trial in San Severo, Italy, researchers grew six crops under solar panels that tracked the sun. The results were mixed. The deep shade helped stop water loss from evapotranspiration by 81.1%. However, that same shade also reduced fresh plant biomass by as much as 48.8%. If you have ever wondered whether solar farms and farmland must compete for the same land, this study offers a clear answer. The study is relevant because it connects crop production, water use, and solar energy.
