Engineering Notes

Floating solar arrays must withstand wind, waves, currents and changing water levels. Learn how mooring lines, anchor types and site-specific engineering keep FPV plants safely in position.

Is your lake, reservoir, quarry, industrial basin or port suitable for floating solar? Use this practical checklist to assess site conditions, access, mooring, grid connection, environmental constraints and project viability.

Floating solar reliability depends on understanding the real forces acting on every component. Discover how site-specific load analysis, fatigue assessment and properly engineered mooring systems help FPV plants withstand decades of wind, waves and changing water conditions.

Floating solar can do more than generate renewable electricity. With careful site selection, ecological design and long-term monitoring, it may also support aquatic habitat enhancement.

HelioRec’s W300A floating solar demonstrator in Brest Port combines clean energy generation with advanced real-time monitoring. The 10 kWp platform collects marine and structural data to validate and optimise floating solar technology for larger coastal and port applications.

Learn how the Environmental Impact Assessment process works for floating solar projects in Europe, including the key stages, realistic 18–24-month timeline, typical costs, and how low-impact system design can simplify permitting.

HelioRec has deployed a 2 kWp floating solar demonstrator at Les Salins in Arles, France, to validate floating solar technology in one of the world's most challenging hypersaline environments. The project evaluates corrosion-resistant materials, mooring systems, and electrical components exposed to salt-saturated water and salt spray, paving the way for future large-scale floating solar power plants in highly saline industrial and coastal locations.

How do you know if a floating solar system is ready for real waves? Discover how HelioRec tested its technology in one of Europe's leading ocean engineering wave tanks, why experimental validation is essential for floating solar innovation, and what every FPV developer should know before deploying a project at sea or in nearshore environments.

What makes a floating solar project attractive to investors and lenders? From proven FPV technology and third-party certification to realistic floating solar cost assumptions, insurance, and revenue models, bankability goes far beyond engineering. Discover the key factors that determine whether a floating solar power plant can secure financing and deliver reliable returns over its lifetime.

Introduction Floating photovoltaic (FPV) technology is rapidly expanding beyond lakes and reservoirs into more challenging environments such as ports, industrial basins, and nearshore areas. While these new applications unlock significant opportunities for renewable energy generation, they also introduce new engineering challenges - especially wind loading. To better understand these challenges, HelioRec collaborated with leading academic and research institutions: Faculty of

Introduction Floating solar is no longer limited to calm inland reservoirs. Across Europe and globally, developers, ports, and industrial operators are now looking toward coastal and nearshore waters as the next frontier for renewable energy deployment. Ports, sheltered bays, industrial basins, and maritime infrastructure offer enormous untapped potential for floating photovoltaic (FPV) systems. These locations already have strong electricity demand, existing grid infrastruct

Introduction Solar PV can be deployed in three main forms: ground-mounted, rooftop, and floating. Each addresses a different combination of available surface, project scale, and consumption profile. Floating solar (FPV) is most often benchmarked against ground-mounted systems, since both are typically utility-scale and grid-connected. In practice, however, asset owners considering on-site generation may also compare FPV with rooftop options - particularly on industrial, port,

Introduction Floating solar design is strongly influenced by environmental loads. Wind, waves, current, and water-level variation do not act independently; together they determine how the floating platform moves, how loads are transferred through connectors and support elements, and how the mooring system must be configured to keep the plant stable and serviceable over time. For a professional project, these conditions are not treated as secondary details. They are core desi

Introduction A floating solar power plant is a photovoltaic installation deployed on a water surface rather than on land or on a rooftop. The system is typically installed on lakes, reservoirs, industrial basins, or other sheltered water bodies where the environmental conditions, access constraints, and operating requirements are compatible with floating infrastructure. At a basic level, the concept combines conventional PV modules with floating support structures, connector

The 8kW off-grid floating solar power plant in Tanzania was succesfully installed in collaboration with AquaBioTech Group , marking our first step in East Africa! This project is part of the EU-Horizon initiative, PrActiCe ( more information ). Our innovative solar system has been installed on two artificial ponds in Morogoro, creating a Living Lab that has already generated more than 700kWh of clean energy since July 5th. This small project is a significant milestone for us

We are thrilled to announce that HelioRec, in collaboration with Centrale Nantes , has successfully completed wave tank testing of the W200CM model! The full-scale prototype was manufactured in Bretagne at EMP ROTOMOULAGE and meticulously assembled by the HelioRec team, with invaluable assistance from the Bassins d'essais de Centrale Nantes team. Our tests were conducted under various conditions, including different sets of regular and irregular waves, reaching a maximum wa
