At Sun’Agri, our research and results demonstrate the utility and numerous benefits of agrivoltaics for improving wine quality in vineyards. Inspired by advancements in this field, an article in Wine Spectator highlights the use of dynamic photovoltaic shutters in vineyards, an approach that we have effectively implemented and enhanced through our research.

Innovation and concrete results for wine quality

Sun’Agri’s dynamic solar panels, developed and tested in pilot vineyards in southern France, are designed to create optimized microclimates for vines. These installations enable the production of grapes with lower alcohol potential, higher acidity, and enhanced aromatic profiles. “We use dynamic photovoltaic shutters to precisely adjust the exposure of vines to sunlight while protecting them from climatic hazards, such as heatwaves or frost,” explains Nathanaël Kasriel, Deputy Director of Sun’Agri.

Note: To date, 36 vineyard and orchard operations are already equipped with agrivoltaic systems, and 60 more are under development.

Positive impacts on viticulture

Our research results show healthier vines and increased yields between 30 to 60% depending on the grape varieties. This technology also significantly reduces the need for irrigation, a major asset in regions often faced with drought. Discover the results of the 2024 harvest: +30% yields thanks to agrivoltaics.

Economic viability of agrivoltaics

Agrivoltaics not only offer an environmental advantage but also an economically viable solution. “In France, particularly in Mediterranean areas, investment in agrivoltaic installations proves to be profitable on its own,” emphasizes Nathanaël Kasriel.

Farmers, investment funds, or independent power producers can expect a positive return on investment thanks to the combined production of energy and improved agricultural yields.

What’s next?

Encouraged by promising results, we plan to extend our research to white grapes, such as Viognier, to deepen our understanding of the effects of agrivoltaics on the aromatic profiles of white wines. These new studies, set to begin in 2025, aim to further refine our agrivoltaic technologies.
