Description
VSUN 590W TOPcon Bifacial (Pallet of 31) Assembled in USA VSUN590N-144BMH-DG
Made in USA
The VSUN590N-144BMH-DG is a high-output N-type TOPCon bifacial dual-glass solar module designed for utility-scale, commercial, and large ground-mount installations. Built with advanced TOPCon technology and multi-busbar (MBB) cell design, it delivers strong efficiency, improved temperature performance, and long-term reliability with low annual degradation.
Key Technology
-
N-Type TOPCon Cell Technology
Higher power output with improved long-term performance and lower degradation versus conventional technologies. -
Bifacial Dual-Glass Construction
Bifaciality of 80% ± 10% supports additional rear-side energy gain depending on albedo and racking height. -
MBB Technology with Circular Ribbon
Enhanced current collection, better performance under partial shading, and improved reliability. -
Strong Mechanical Load Rating
Tested for +5400 Pa front and -2400 Pa rear loads for demanding site conditions.
Best Uses
-
Utility-Scale Solar Farms
High wattage and bifacial gains help reduce BOS costs and improve project economics. -
Commercial & Industrial Ground-Mount
High efficiency and dual-glass durability support long-life performance on large systems. -
Hot & High-Irradiance Environments
Low power temperature coefficient helps maintain output as operating temperatures rise.
Warranty
-
Product Warranty: 12 years (Quality Assurance)
-
Performance Warranty: 30-year power output guarantee
-
Degradation: 1.0% first year, then 0.40% annually through year 30
