DSND Back Contact Solar Panel 625W~660W
High efficiency dual-glass bifacial N type solar module
DSND 625~660 Series – Back Contact Solar Modules for Utility-Scale Excellence
Maximum Energy Output Over the Entire Lifecycle
The DSND 625~660 series is engineered for utility-scale applications, offering sustained high-performance energy generation throughout its operational life. Enhanced system design results in over 6.5% increased energy yield, driving greater long-term efficiency.
Advanced Back Contact with TaiRay Wafer Integration
Powered by TaiRay wafer and back contact (BC) technology, these modules deliver outstanding reliability, superior current collection, and reduced energy loss-ideal for high-demand solar installations.
Smart Manufacturing & Quality Standards
Built under DS's intelligent manufacturing systems and rigorous lifecycle quality protocols, these modules meet the highest standards in durability, consistency, and performance.
DS Technology for High Conversion Efficiency
Incorporating gettering processes and microcrystalline silicon (µc-Si) technology, DSND modules achieve improved cell-level efficiency and enhanced overall power output.
Up to 95% Bifacial Gain
Thanks to a naturally symmetrical bifacial design, the modules capture additional irradiance from the rear side, significantly boosting energy yield.
PIB Sealing for Harsh Environments
Framed with integrated PIB coatings, each module exceeds IEC salt-mist corrosion resistance Level 8, ensuring strong performance in coastal and humid regions.
Utility-Ready, Cost-Efficient Solar Solutions
Optimized for large-scale solar farms, the DSND 625~660 series helps reduce Balance of System (BOS) costs and achieve a lower Levelized Cost of Energy (LCOE), maximizing ROI for investors and developers.
