Shanghai, Jun. 11, 2025 - DAS Solar, a leader in N-type PV technology, made a major appearance at SNEC with its signature “One Core, Three Branches” high-efficiency product portfolio and all-scenario PV solutions spanning ecological, urban, and floating applications. As one of the world's most prestigious solar events, SNEC integrates policy trends, product innovation, cutting-edge technology, supply chain collaboration, financial services, and business opportunities, making it a critical barometer for the industry's development.

DAS N-type: Pioneering Excellence with “One Core, Three Branches” Strategy

As PV technology evolves at breakneck speed, DAS Solar has consistently focused on the N-type pathway since its founding. With sustained R&D efforts, the company's TOPCon 5.0 cells have now reached over 27% average mass production efficiency, with an open-circuit voltage of 746 mV, placing DAS Solar at the forefront of N-type innovation.

At the event, DAS Solar showcased a range of flagship products, including high-efficiency TOPCon 5.0 modules, TSiP 2.0 perovskite tandem modules, and all-black Diamond series back-contact (DBC) modules featuring N-type DBC 3.0 Plus technology.

Among the highlights is DAS Solar's 745W N-type module with steel frame, engineered for high-reliability, high-load environments. The module features a large-format 78-cell design with 23.4% efficiency and excellent UVID resistance, delivering long-term energy yield and lower LCOE. The steel frame is not only more environmentally friendly by offering 80% lower carbon emissions than aluminum, but also provides superior corrosion resistance and self-healing edge protection through zinc-aluminum-magnesium coating, making it ideal for utility installations.

Leveraging its deep technical foundation, DAS Solar continues to push forward with its TOPCon+ platform, integrating novel materials and tandem technologies. Its latest large-format perovskite-silicon four-terminal modules now deliver up to 755W with 26.8% efficiency, representing a major milestone toward commercialization.

Since 2020, the company has been pioneering DBC cell and module development by combining TOPCon tunneling oxide layers with full-area passivated contact structures. The latest all-black DBC modules feature a busbar-free front design for maximum light capture and seamless integration into architectural aesthetics. Module efficiency has reached 24.8%, and cell efficiency has surpassed 27.2% in mass production. The DBC series is also equipped with advanced electrical safety features, including string-level arc fault protection and module-level rapid shutdown, reducing voltage to 0V within one second—a key innovation to address fire safety risks in PV systems.

DAS ECO: Flexible Mounting System Expands Ecological Integration

In the DAS ECO PV scenario solution area, the company presented its flexible mounting system for ecological scenarios such as deserts, hills, and farm land. Using pre-stressed cable structures, the mounting system offers high wind resistance, large spans, and elevated clearance, ideal for uneven terrain. The slide-in module installation method increases installation efficiency while reducing system costs. Compared with traditional mounting, DAS Solar's flexible design saves more than 25% in land use, enabling harmonious coexistence between PV arrays and the natural environment.

In southern China, DAS Solar's flexible mounting system was deployed in a fishery complementary PV project. After enduring level-17 Super Typhoon Yagi, the system remained fully intact and later passed strict post-storm testing without microcracks, earning strong recognition from the project owner.

At the event, DAS Solar also introduced its flexible tracking system, equipped with an advanced flexible drive system that precisely follows the sun's trajectory. Compared to fixed mounting, this system increases energy output by over 10% while significantly lowering failure rates and O&M costs. With its adaptable layout, the system addresses challenges in land reuse and cost optimization, enabling widespread deployment in agri-PV, forestry-PV, and fishery complementary PV applications.

DAS Floating: Leading Aquatic PV Innovation with Long-Term Value

In terms of DAS Floating PV scenario solution, the company displayed its fully self-developed floating solar ecosystem—from floats and anchors to racks, modules, and O&M tools. For inland applications such as lakes, reservoirs, and subsidence areas, DAS Solar uses marine-grade polymer floats that are resistant to UVID and saltwater corrosion, ensuring high durability and environmental compatibility.

To address the challenges of offshore deployment, DAS Solar has developed specialized high-sealing, UVID-resistant and salt-resistant floating modules with a 25-year service life. These modules features a composite frame that reduces costs by 20-25% compared to aluminum, while maintaining long-term mechanical strength and environmental resilience. The floating system also delivers ecological benefits: the shading reduces water evaporation and inhibits the growth of harmful aquatic plants, contributing to water conservation and quality improvement.

Today, DAS Solar floating systems are operational across multiple regions, including coastal demonstration projects deployed in aquaculture farms, thermal outfall zones, and offshore islands, all of which have proven the system's resilience under harsh marine conditions.

DAS Urban: Customizable Lightweight Modules Support Sustainable City

Speaking of DAS Urban PV scenario solution, the spotlight is on lightweight modules designed for distributed urban applications. The ECOSKY series includes frameless back-contact lightweight modules that are 50-70% lighter than conventional modules depending on configuration. These are installed using adhesive systems—no drilling, no framing, no complex reinforcement—making them ideal for flat roofs, metal panels, carports, and other weight-sensitive structures.

The modular design supports a wide range of applications from commercial rooftops to airport tarmacs and highway sound barriers. In high-rise settings, DAS Solar also showcased balcony PV kits in various colors, complete with mounting brackets, turning idle outdoor space into micro-energy hubs. The booth also featured lifestyle PV products such as solar-powered backpacks and foldable charging panels, highlighting the growing integration of renewable energy into everyday life.

Building a Smarter, Greener, and Brighter Future

With N-type technology as its core, DAS Solar continues to lead through forward-looking innovation and system-level integration. From technology breakthroughs to intelligent manufacturing and scenario-based applications, the company remains focused on delivering value-driven, high-efficiency solutions across diverse application scenarios.

Looking ahead, DAS Solar will continue to deepen its global strategy by expanding partnerships and strengthening its presence across global markets. With technology as the engine and sustainability as the goal, the company is working together with global partners to unlock the full potential of solar energy, and shape a cleaner, more sustainable energy future for all.
