Shanghai, Apr. 26, 2025 - As the world marked World Intellectual Property Day with a renewed focus on empowering innovation through IP, DAS Solar took part in the China Intellectual Property and Innovation Summit (CIPIS) in Shanghai—one of APAC's leading conferences focused on IP strategy and technological innovation. Mr. Zhijun Chen, Director of Intellectual Property at DAS Solar, was invited to join a panel discussion on “Safeguarding Innovation through Intellectual Property” and delivered a keynote titled “High-quality Patent Development Driven by Industrialization”.

In his presentation, Chen emphasized the importance of aligning patent strategies with each phase of a company's growth. For early-stage businesses, building a foundational IP portfolio is critical, and in the growth phase, comprehensive protection around core technologies becomes key. As companies mature, monetizing IP through licensing or transfers can unlock commercial value, while in transition phases, IP transformation and reuse can support business restructuring.

DAS Solar's results speak for themselves. As of April 2025, the company has filed 1,302 patent applications and secured 626 granted patents. These have contributed to over RMB 10 billion in revenue, underscoring the strategic role IP plays in value creation. Meanwhile, DAS Solar ranks among the top patent holders in the renewable energy sector and continues to expand its global IP presence across a range of emerging technologies.

At the core of DAS Solar's innovation strategy is its focus on N-type PV technology and future-oriented solar applications. The company operates under a “One Core, Three Branches” R&D model—centered on TOPCon, and supported by DBC, TSiP, and SFOS technologies. Its latest tandem solutions have achieved up to 33.5% efficiency in two-terminal designs, while four-terminal tandem modules have already entered pilot deployment. DAS Solar is also advancing toward 40% theoretical efficiency through its SFOS research, in partnership with leading academic institutions.

Beyond cell technology, the company is expanding its all-scenario PV system solutions, including DAS Floating scenario solution, DAS ECO scenario solution, and DAS Urban scenario solution. In the offshore floating PV sector, DAS Solar has built a fully integrated supply chain covering float structures, anchoring systems, support structures, modules, and O&M platforms. Novel materials and underwater cleaning systems are being deployed to combat salt buildup, corrosion, and biofouling, helping bring down system costs to near onshore levels. With its original proprietary aluminum-polymer material, DAS Solar has cut costs while enhancing durability. Addressing challenges like biofouling, corrosion, and salt accumulation, the company has deployed underwater cleaning robots and high-pressure water jetting technology to boost offshore O&M efficiency. These innovations have brought the cost of offshore PV systems close to parity with onshore projects. To date, the company holds more than 140 patents related to floating PV technology.

With the global push toward clean and sustainable energy, intellectual property and innovation are becoming defining factors in market competitiveness. DAS Solar remains committed to advancing both, investing in long-term R&D and actively collaborating with technology partners across the value chain. Through a strong IP framework and continuous innovation, the company aims to help accelerate the global energy transition and deliver high-value solar solutions for a cleaner future.
