As the global PV industry accelerates toward higher efficiency, greater scenario specialization, and lower carbon intensity, conventional one-size-fits-all modules are increasingly unable to meet the demands of diverse application environments.

DAS Solar's newly launched DBC (Diamond series back-contact) series breaks through these limitations by placing all-scenario adaptability and performance optimization at the center of product development. Anchored in a deep understanding of real-world deployment challenges, the DBC series targets three core application domains—lightweight urban rooftops, utility ground-mounted power plants, and C&I distributed systems, delivering integrated, scenario-specific solutions that redefine both the technical ceiling and application boundaries of PV modules.

Lightweight Series RF96TE: Redefining Urban Rooftops with Structural Efficiency and Aesthetic Integration

As urban skylines continue to evolve, aging buildings and color-steel rooftops present increasingly strict requirements for module weight, installation flexibility, and architectural compatibility. Designed specifically for these constraints, the RF96TE lightweight DBC module introduces a new benchmark for rooftop PV deployment by combining structural weight reduction with refined visual integration.

The series is engineered to address load-sensitive rooftops while maintaining high safety margins and visual harmony. Its adaptability makes it suitable for older residential buildings, industrial color-steel roofs, and other scenarios where both structural limitations and aesthetic considerations are critical. By integrating full-black visual design with advanced thermal and electrical optimization, the module enables seamless rooftop deployment without compromising building integrity or visual coherence.

At the core of this design is a breakthrough in lightweight engineering. The module adopts a 1.1 mm fully chemically tempered front glass, achieving a significant reduction in overall weight compared with conventional glass configurations while preserving mechanical strength. This structural optimization effectively resolves rooftop load concerns and expands the addressable market for distributed PV systems. At the cell level, optimized design significantly suppresses hotspot formation, reducing hotspot temperatures by approximately 50°C compared with conventional TOPCon modules and ensuring stable operation even under partial shading conditions. The fully black, low-reflection surface further enhances architectural integration, allowing the module to blend in building envelope. Installation efficiency is also substantially improved through compatibility with bracket-free adhesive mounting solutions, enabling rapid deployment and reduced on-site construction complexity.

Advanced emitter passivation and composite technologies further enhance durability, effectively suppressing ultraviolet-induced degradation and limiting power loss to below 1.5% after prolonged UV exposure. Combined with uniform thermal-field string welding and low-stress structural design, the series delivers long-term reliability validated through multiple IEC-level reliability tests, ensuring consistent energy output over its operational lifetime.

Utility Series DH132TE: Delivering High-Power Reliability in Desert and Gobi Environments

In expansive desert and barren landscapes, where extreme temperatures, strong winds, and high irradiance define operating conditions, utility PV systems demand uncompromising reliability, high output, and stable performance under weak-light conditions. The DH132TE series has been engineered specifically to meet these challenges, establishing itself as a high-power solution for large-scale ground-mounted power plants.

The module's design prioritizes high output, enhanced durability, and superior energy yield, making it particularly suited for desert, plateau, and other harsh environments. Through electrode pattern optimization and process innovation, the series achieves a weak-light response exceeding 95%, enabling sustained power generation during early morning, late afternoon, and low-irradiance conditions. This improvement directly contributes to lower LCOE and higher long-term project returns.

Structural optimization further enhances system performance and operational efficiency. The frame design eliminates water and dust accumulation zones, reducing soiling losses and maintenance requirements while delivering measurable system-level energy gains. High mechanical strength is ensured through rigorous static load validation, with power degradation remaining below one percent even after exposure to extreme load conditions. This capability allows the module to operate reliably in regions characterized by high wind speeds, heavy snow loads, and abrasive sand environments. Precision spacing and seamless structural integration further elevate module output, contributing additional power gains and pushing conversion efficiency to new levels.

Durability is reinforced through precision thermal-field control string welding and UV-resistant laminated films, ensuring long-term power stability even in high-altitude regions with intense ultraviolet radiation. Together, these innovations position the series as a cornerstone solution for next-generation utility solar projects.

C&I Series DH96TE: Protecting Performance in High-Pollution Environments

Industrial and commercial rooftops present a distinct set of challenges, including persistent dust accumulation, oil residue, and chemical emissions that can compromise module performance and increase maintenance costs. The series is designed to address these conditions directly, serving as a reliable energy solution for factories, processing facilities, and other pollution-intensive environments.

Optimized for industrial rooftops, the series integrates anti-soiling design, enhanced ultraviolet resistance, and high energy yield into a single, robust platform. Its frame architecture prevents dust and contaminants from accumulating, allowing pollutants to naturally shed from the surface and reducing cleaning frequency. This feature significantly lowers operational expenditure while maintaining stable output in demanding environments.

Advanced surface and passivation technologies further protect the module against combined ultraviolet exposure and chemical corrosion. Even after extended UV exposure, power degradation remains tightly controlled, ensuring long-term generation stability. The fully black appearance not only enhances visual consistency across industrial buildings but also helps mitigate glare-related concerns in densely developed areas. Output is further boosted through precision spacing and weak-light optimization, delivering measurable gains in total energy yield and reinforcing the module's value proposition for commercial and industrial users.

Thermal management is also significantly improved, with hotspot temperatures reduced by approximately 50°C compared with conventional TOPCon modules. This enhancement minimizes the risk of hotspot-related failures and ensures safe, stable operation under partial shading and complex rooftop conditions.

Continuous Innovation Driving Industry-Leading Efficiency

Through sustained technological iteration, DAS Solar's DBC (DAON-BC) platform has achieved cell efficiencies of up to 27.77%, module efficiencies exceeding 24.61%, and output power approaching 665 W. These advancements place the DBC series firmly at the forefront of industry performance benchmarks and demonstrate DAS Solar's commitment to pushing efficiency boundaries through applied innovation.

From lightweight urban rooftops to large-scale utility power plants and pollution-intensive industrial applications, the three DBC series are purpose-built solutions tailored to distinct scenario requirements. Each design decision is rooted in practical deployment experience, addressing real-world challenges through material innovation, process refinement, and structural optimization. Together, these pathways deliver higher safety margins, lower system costs, improved efficiency, and enhanced environmental compatibility.

As PV applications continue to expand from flat terrain to complex landscapes and from single-purpose generation to integrated "PV+" models, DAS Solar's DBC series provides a reliable technological foundation for applications spanning building integration, industrial energy systems, and desert ecological management. Looking ahead, DAS Solar will continue to deepen its focus on scenario-driven innovation, advancing DBC technology to empower the global PV industry's transition toward higher quality, greater sustainability, and long-term value creation.
