Ocean Sun pioneering floating solar power solutions
- Published 12 August 2026; updated 21 September 2026; estimated reading time 2 minutes. Listed as available under Solar energy (Energy).
- Ocean Sun’s patented floating-solar design uses modified silicon solar modules mounted on large floating structures and supported by a thin hydro-elastic membrane. The page says the membrane helps prevent wave breakage and saltwater intrusion. Floating installations can use reservoirs and coastal waters, placing generation near population centres and using water as a heat sink to increase panel output.
- The company says the structures are built for harsh conditions and certified to withstand category 4 typhoons or winds up to 275 km/h. DNV GL reviewed the system against design guidelines originally developed for Norwegian fish farms. Components are described as using environmentally friendly materials with a low carbon footprint.
- Ocean Sun reports that at a Singapore site its water-cooled panels achieved almost 11% higher efficiency than an air-cooled system. The page presents the system as a low-cost, high-performance option; it gives no detailed levelized-cost figure.
- Market context: a 2018 World Bank/Seris Singapore report is cited for potentially terawatt-scale floating solar capacity on freshwater reservoirs. Ocean Sun says it has installed systems in Norwegian fjords, Singaporean waters and at the Magat hydropower dam in the Philippines. It also cites an extensive intellectual-property portfolio as supporting capital costs, material use, logistics and levelized energy costs.
- The page opens with the statement that half the global population lives in coastal areas, framing floating solar as generation close to demand. It also notes the limitations of land-based solar sites near population centres.
- Linked to SDG 7, Affordable and clean energy, and SDG 9, Industry, innovation and infrastructure, through renewable generation and siting near users to reduce transmission costs.
