Les Serres des Marais: first greenhouse to adopt Voltiris solar modules

‍

Les Serres des Marais, operated by Alexandre Cudet and Patrice Brestaz, is Switzerland’s largest producer of cherry tomatoes, with over 10 tons produced daily. Located in the Canton of Geneva, their state-of-the-art greenhouse covers more than 6 hectares.

In 2023, convinced by the potential of Voltiris' innovative solar solution, Les Serres des Marais became the first commercial greenhouse to implement the technology—a major milestone in Voltiris’ development.

The project received support from Romande Énergie, the Swiss Federal Office of Energy, the Fonds VitaleVert of the Services Industriels de Genève (SIG), and the Foundation for the Climate.
