Products Description
Maximize your project's energy yield and long-term investment security with our high-efficiency TOPCon solar panel series. Engineered specifically for commercial utility-scale projects, distributed generation, and heavy-industrial microgrids, this bifacial dual-glass module leverages next-generation N-type technology to drive down the Levelized Cost of Energy (LCOE) while delivering exceptional reliability in extreme environments.
Product Features
N-type Technology
N-type modules with Tunnel Oxide Passivating Contacts (TOPCon) technology offer lower LID/LeTID degradation and better low light performance
HOT 3.0 Technology
N-type modules with JinkoSolar's HOT 3.0 technology offer better reliability and efficiency
Dual-Sided Power Generation
Dual-sided power generation gain increases with backside exposure to light, significantly reducing LCOE
Mechanical Load Enhanced
Certified to withstand: 6000 Pa front side max static test load 4000 Pa rear side max static test load
SMBB Technology
Better light trapping and current collection to improve module power output and reliability
Anti-PID Guarantee
Minimizes the chance of degradation caused by PID phenomena through optimization of cell production technology and material control

Industry-Leading 30-Year Linear Power Warranty
Secure your long-term asset performance with an uncompromising warranty framework. We provide a 15-year product warranty alongside a 30-year linear power warranty. With a guaranteed first-year degradation of less than 1% and a mere 0.40% annual degradation over the next 30 years, this module ensures steady, predictable energy yields for decades.
FAQ
Q: How do the long-term degradation guarantees translate to financial asset protection?
A: We back this product with an industry-leading 15-year product warranty and a 30-year linear power warranty. The first-year degradation is strictly guaranteed to be under 1%, with a negligible 0.40% annual degradation over the remaining 30 years.
Q: Which international quality and safety certifications does this module hold?
A: This module complies fully with the latest international tier-1 standard criteria, holding IEC 61215:2021 and IEC 61730:2023 certifications.
Q: What is the exact quantity per 40'HQ shipping container?
A: Standard packaging configures 37 pieces per pallet, packed double-stacked at 74 pieces per stack. A full 40'HQ container fits exactly 962 pieces.
Q: What are the default connector and cable configurations?
A: The default setup includes an IP68-rated junction box paired with standard **4.0 mm² cables-measuring (+) 400 mm and (-) 200 mm in length. Default connectors are JK03M or JK03M2, but standard MC4 and MC4-EVO2** connectors are fully available upon request.
Q: What is the power measurement tolerance, and do you sort modules to prevent mismatch losses?
A: The standard power measurement tolerance is tight at 3%, but we enforce a positive power tolerance of 0-3% on all shipments.
