The Bagatelle solar plant: a complex site brought back to life

On a site with complex terrain and strict environmental constraints, Ecostal supported the construction of an 18 MWp solar plant. With hybrid structural solutions and carefully managed logistics, we helped turn a sensitive area into a high-performing, long-lasting energy asset.

Project details

• Location: France
• Total installed power: 18 MWp
• Number of modules: 29,000
• Estimated annual production: 19,000 MWh
• Equivalent consumption: electricity for 8,500 people
• Environmental impact: 5,700 tonnes of CO₂ avoided each year

Site specifics

The plant sits on land that is both flood-prone and environmentally sensitive. Several exclusion zones were defined to protect local wildlife and vegetation, along with an area where drilling was strictly prohibited. These technical and ecological constraints required a precise engineering approach, where every design decision needed to balance energy performance, site safety, and environmental protection.

Our solutions

To meet these challenges, SigueSol deployed hybrid structures engineered specifically for heterogeneous terrain. Their anchoring flexibility and resistance to extreme conditions ensure optimal stability—even in flood zones. Combined with carefully coordinated logistics, these solutions enabled the efficient installation of 29,000 photovoltaic modules, delivering an annual output of 19,000 MWh.

This level of precision reflects our ability to adapt both technology and support to the realities of each site—without compromising on reliability or long-term performance.
