DAS Solar, a leader in N-type PV technology, is helping drive China's energy transition from land to open sea. The nation's first open-sea floating photovoltaic (FPV) project developed at Sinopec Qingdao Refining & Chemical Company has officially entered operation. This milestone project, built entirely with DAS Solar's high-efficiency N-type modules, marks a breakthrough in offshore renewable energy development and underscoring how technological innovation is accelerating the clean energy revolution.
Located within the Qingdao Refining Hydrogen Energy Demonstration Park, the project spans approximately 60,000 square meters and boasts an installed capacity of 7.5 MW. The entire installation utilizes DAS Solar's high-efficiency N-type modules. Unlike conventional pile-mounted systems, this floating system features a dynamic design that rises and falls with the tides, reducing the distance between the modules and the water's surface to just one-tenth of that of traditional structures. This near-surface layout creates a natural seawater cooling effect, lowering module operating temperatures by 3-5°C and increasing power generation efficiency by 5-8%. The project is expected to generate 16.7 million kWh of green electricity annually, offsetting approximately 14,000 tons of CO₂ emissions and cutting investment costs by around 10% compared to traditional methods. Its success opens new pathways for energy transitions across coastal cities, islands, and offshore platforms.
With 18,000 kilometers of coastline and over 3 million square kilometers of territorial waters, China's offshore renewable potential exceeds 100 GW. The nation's 2025 energy policies explicitly support offshore aquaculture and the construction of marine ranches. Under this policy framework, the "blue granary" strategy continues to advance steadily, with the integrated development of "PV + marine ranching" emerging as a mainstream trend.
As the core technology provider for this project, DAS Solar has placed strong emphasis on the innovation and application of offshore PV in recent years. Its floating PV systems feature proprietary aluminum-like polymer composite materials, which offer significant advantages over traditional HDPE-based systems. These materials are highly environmentally friendly and exhibit exceptional weather resistance, durability against UV, heat, and salt mist, and enhanced safety and ease of installation. They also improve power generation per unit area and offer excellent wind and wave resistance, maintaining stable operation even under extreme sea conditions, and maximizing returns for clients.
To date, DAS Solar holds over 140 patents related to floating PV systems. Its DAS Floating solution—anchored by its proprietary aluminum-polymer composite—offers outstanding resilience, anti-corrosion performance, and major breakthroughs in cost-efficiency. The success of this project validates the strength of DAS Solar's "technology-driven, scenario-based" strategy and reflects the broader ambition of Chinese solar companies to lead the global transition from land-based installations to offshore deployments.
Looking ahead, DAS Solar will continue to chart a course toward deeper and broader marine territories, actively engaging in global offshore renewable energy development and cooperation. Through innovation and collaboration, the company aims to contribute to the global energy transition and the shared goal of carbon neutrality.
