The pilot aims to demonstrate the viability of offshore floating PV by testing its structural integrity, mooring and electrical systems. It also serves to gather practical knowledge on manufacturing, assembly, offshore installation and maintenance—key factors for future commercial-scale deployment.
12 kilometers off the Scheveningen coast
Merganser is a 0.5 MW pilot system located 12 kilometres off the coast of Scheveningen in the Dutch North Sea. The scalable concept comprises six interconnected platforms designed to withstand harsh offshore conditions. The floating units have been successfully moored in 20-metre-deep waters. RWE continues to support the project with its offshore expertise and technical know-how.
Accelerating the deployment of offshore floating PV
Sven Utermöhlen, CEO of RWE Offshore Wind: “Standalone or also in combination with offshore wind farms, offshore floating solar could open up further offshore renewable energy opportunities – especially for countries with lower average wind speeds but lots of sunlight. With Merganser, we are gaining unique insights and first-hand experience in one of the most challenging offshore environments in the world.”
Following the waves like a carpet
Taking solar farms offshore requires technology capable of withstanding harsh marine conditions. SolarDuck’s triangular platform is engineered to float several metres above the water, flexing with the waves like a carpet. This keeps critical components dry, clean and stable, while protecting the structural integrity of the semi-submersible floating system. The design recently received the world’s first certification for offshore floating PV (OFPV) from Bureau Veritas.
SolarDuck
Koen Burgers, CEO SolarDuck: “The successful installation of Merganser is proof of the dedication of SolarDuck’s team to electrify the world with offshore floating solar. However, we are not doing this alone. Our project partner, RWE, is a supporter of our technology and vision, in addition to other partners such as TNO, TU Delft, MARIN, and Deltares. Together with numerous supply chain partners, including Damen Shipyards, TMA, and Norsk Hydro, we have turned hard work into a positive change for the energy space.”
More than 180 monitoring sensors
The combination of RWE´s leading global market position in offshore wind and SolarDuck´s technological ingenuity sets the perfect base for accelerating the deployment of OFPV. Over the coming two years, Merganser will be monitored remotely with its more than 180 sensors fitted to monitor structural loads, connector and mooring loads and electrical performance, among other important performance criteria.

Further to the above, Deltares – a Dutch independent institute for applied research – will support an extensive monitoring campaign on the ecological impact of OFPV. (hcn)
