After demonstrating its performance in real-world conditions, the new Neluma™ Floating PV solution now enters large-scale, continent-based deployment, with strong prospects in Europe, India, and Brazil.
Neluma™ is a turnkey floating PV solution designed to address the limits of existing systems. It combines high layout modularity to adapt to various lake configurations, easy and lightweight installation, and an eco design approach that helps reduce carbon footprint and environmental impact.
Montmélian pilot site: proven in real conditions
The Neluma™ concept has been tested under real world conditions since 2024, with a first pilot installation of around 260 kWp in Savoie, France, in partnership with Enercoop, a pioneer in renewable electricity. The project confirmed the system’s robustness, performance, and ability to integrate into its environment.

Modularity as a core advantage
Neluma™ adapts to a wide range of lake configurations through flexible layouts, enabling efficient solar energy capture and production. It delivers strong performance through flexible module layouts (north‑south, portrait, up to 15° tilt) and compatibility with almost every PV module on the market.
Modularity also shapes installation with the Neluma™ MobileFactory, an innovative industrialization process: components are produced and assembled directly on the project shoreline. This approach offers an alternative to land artificialization while optimizing space use, and helps reduce transport needs, logistics complexity, and overall project costs, bringing new perspectives to the manufacturing and deployment of floating solar plants.

Eco-designed approach
To limit the environmental impact of energy production on water—an inherent challenge of floating PV—the system has been developed with an eco designed industrial approach that aims to go beyond standard industry practices. By relying on a mobile micro factory production process on site, it reduces transport needs and lowers long term footprint on lake shores, without permanent soil sealing. Its aluminum catamaran style structure, combined with a flexible anchoring and mooring system, also helps limit material use and reduce shading on water surfaces.

Strong prospects for global rollout: a step further for ARaymond
ARaymond has initiated its international deployment with first installations in Goiânia, Brazil, and Dhule, India. In Brazil, Neluma™ aims to support agricultural producers in generating solar energy from their water reserves. In India, development targets the significant potential of large‑scale reservoirs. In Europe, the solution targets quarries and industrial water bodies, addressing constraints on land use.
Known for its PV fastening systems, ARaymond has already contributed to more than 22 GW of ground‑mounted solar capacity worldwide. With Neluma™, the company’s expansion into turnkey floating solar systems marks a significant step in its scale‑up and diversification strategy.

Montmélian pilot: from concept to reality with Enercoop
ARaymond developed the Montmélian pilot based on a patent acquired from the French start‑up HeliosLite, further advancing the floating PV concept in collaboration with Enercoop, a cooperative renewable electricity supplier committed to environmental protection and solidarity. Operational since 2024, the system was deployed using ARaymond’s mobile micro‑factory, directly on the Alpespace site—a former gravel pit reservoir near Grenoble, within the territory of the Communauté de Communes Cœur de Savoie—in coordination with the local stakeholders, including the fishing community.
Covering around 20,000 m²—about 7% of the lake surface—the installation has a capacity of just over 260 kWp and generates around 310 MWh per year, supplying round a hundred households with renewable energy. Based on a fully recyclable aluminum floating structure, the project demonstrates Neluma™’s ability to combine reliable energy production with careful integration into local uses and ecosystems.
