Munich, May 8, 2025 - DAS Solar, a leader in N-type PV technology, made a powerful impression in Munich with a showcase of its flagship products, including the DAS Black series, Diamond series back-contact (DBC) modules, lightweight modules, etc. Unveiled at at Intersolar Europe 2025, these offerings demonstrated the company's differentiated innovation strategy and high-efficiency product matrix, drawing significant attention from visitors and industry professionals alike.

Germany, a pioneer in solar development since the late 20th century, has seen steady growth in renewable energy demand driven by recent geopolitical tensions and energy security concerns. According to Germany's Federal Network Agency, the country's cumulative installed PV capacity surpassed 100 GW as of January 2025. With a national goal of reaching 215 GW by 2030, Germany continues to maintain its position among the top five global solar markets.

DAS Black Modules: When Efficiency Meets Aesthetics

DAS Solar's Intersolar booth displays the latest 460W N-type DAS Black modules, 630W N-type dual-glass rectangular modules, 470W DBC modules, 500W lightweight modules, and 630W self-cleaning modules. The full portfolio showcases the company's technological strength, product reliability, and versatile application range.

Among the, the N-type DAS Black series, which features options such as black cells, black frames, black or transparent backsheets, is tailored for premium residential and architectural projects where appearance is paramount. In regions like Europe with frequent overcast conditions, these modules deliver superior performance thanks to excellent low-light response and conversion efficiency. Their innovative design also streamlines transport, handling, and installation. Combining aesthetics with advanced functionality, the DAS Black series has become a standout choice in the European residential market.

Pushing Cell Efficiency to New Heights

As a pioneer in N-type technology, DAS Solar continues to drive breakthroughs in TOPCon development. The company's TOPCon 5.0 cells have reached 27% efficiency in mass production, with an open-circuit voltage of 746 mV and module efficiency up to 23.8%.

At the event, DAS Solar's DBC modules drew significant attention. Built on a next-generation N-type back-contact (BC) structure, these modules utilize advanced TOPCon 5.0 tunnel oxide layers and full-passivation techniques. The front side is completely busbar-free, eliminating light obstruction and significantly boosting conversion efficiency. The DBC 4.0 cells have reached 27.2% efficiency and 747 mV in open-circuit voltage, with module efficiency up to 24.8%. Featuring a sleek, modern design and low temperature coefficient, they offer both aesthetic and performance advantages across distributed PV applications.

Addressing UVID with Technological Precision

While N-type modules dominate the market with their high power, low degradation, and bifacial advantages, UV-induced degradation (UVID) remains a concern in large-scale TOPCon deployment. To tackle this challenge, DAS Solar has implemented atomic layer deposition (ALD) technology to enhance the UV resistance of hydrogen-silicon bonds. Partnering with industry-leading material suppliers, DAS Solar also developed a multi-layer encapsulation structure to ensure optimal compatibility between cell and encapsulant. This innovation ensures long-term power stability even under intense UV exposure, reducing maintenance costs and maximizing system performance throughout the module life-cycle.

Differentiated Products for Diverse Scenarios

As competition intensifies across the solar industry, DAS Solar is responding with targeted solutions for niche markets. Its self-cleaning module, featuring an innovative short-edge frameless design, enables rapid drainage of rainwater and dust even on rooftops with low tilt angles (as low as 5°). This reduces hot spot risk and cleaning costs, making it ideal for dusty environments like Southern Europe and the Middle East.

Meanwhile, the lightweight module designed with a glass-free encapsulation structure, weighs just 4.7 kg/m², over 50% lighter than conventional modules. Able to withstand 5400Pa snow load and 2400Pa wind load, it offers high durability, excellent fire resistance, and is well-suited for rooftops with limited structural load capacity, such as metal-clad and aging industrial buildings.

Global Expansion and Project Success Across Europe

DAS Solar continues to propel its globalization strategy with a steady pace. Recognized as a BloombergNEF Tier 1 module supplier, the company has also ranked among the TOP 10 global module shippers, earning PV ModuleTech's bankability A-rating.

With its German subsidiary as the anchor point, DAS Solar has developed a localized network across Europe, covering sales, technical support, and logistics. The company has delivered benchmark projects across Germany, France, UK, Greece, and the Netherlands, spanning utility, C&I, and residential applications, supporting Europe's clean energy transition with tailored “PV+” system solutions.

Against the backdrop of global climate challenges, DAS Solar is committed to advancing innovation, building deeply integrated supply chains, and fostering sustainable partnerships. The company will continue contributing to the global low-carbon transition with resilient, high-performance solar solutions.
