Abstract
This study demonstrates that agrivoltaic systems can deliver measurable benefits for both solar energy production and vineyard performance. Elevated PV modules operated 3.6°C cooler than a conventional ground-mounted system, improving instantaneous module efficiency by around 1.1%. The vineyard canopy and agrivoltaic system design also increased reflected light to the rear of the modules, creating 64% higher rear-side irradiance and significantly improving the energy yield potential of modern bifacial solar panels.
Importantly, these energy gains were achieved without compromising grape production. Grapevine photosynthesis, yield and berry sugar concentration remained unchanged, while berry acidity increased and juice pH decreased. These are valuable quality improvements for wine production in warming Mediterranean climates. Together, these findings strengthen the case for agrivoltaics as a solution that simultaneously enhances renewable energy generation and supports climate-resilient viticulture.
