Qiqiang Solar JKM610N-78HL4-BDV 610W N-Type TOPCon Bifacial Solar Panel
JKM610N-78HL4-BDV | N-Type TOPCon | 156 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Qiqiang Solar JKM610N-78HL4-BDV 610W N-Type TOPCon Bifacial Solar Panel delivers exceptional energy performance for modern solar installations. This advanced module features a nominal power output of 610 Watts with a high efficiency rating of 21.82 percent. Constructed with N-type monocrystalline cells, it utilizes TOPCon technology to minimize degradation and enhance reliability. The bifacial design captures sunlight from both sides, significantly boosting total energy generation. It supports a maximum system voltage of 1500V, making it ideal for large-scale commercial projects. The panel includes a robust 34.6 kg weight and dimensions of 2465x1134x30 mm for easy mounting. With a 12-year product warranty and 30-year linear power warranty, this solar panel ensures long-term value. Its positive power tolerance of 0 to +3 percent guarantees consistent performance under varying conditions. The anti-reflection coating glass and anodized aluminum frame provide superior durability against environmental stress.
Key Benefits
High Power Output: Generates 610 Watts with a 21.82% efficiency rate for maximum energy yield.
Bifacial Technology: Captures light from both sides to increase total power generation by up to 25%.
N-Type TOPCon Durability: Reduces LID/LeTID degradation for better long-term reliability and lower maintenance costs.
Superior Weather Resistance: Certified to withstand wind loads of 2400 Pascal and snow loads of 5400 Pascal.
Extended Warranty Coverage: Includes a 12-year product warranty and a 30-year linear power warranty for peace of mind.
How It Works
This solar panel operates by converting sunlight into electricity using advanced N-type monocrystalline cells with TOPCon technology. The bifacial design allows the module to absorb light from the front and rear surfaces simultaneously. This dual-sided absorption significantly increases the total energy output compared to traditional single-sided panels. The SMBB and Hot 2.0 technologies further optimize light trapping and current collection efficiency. These features ensure that the panel maintains high performance even in low-light conditions or partial shading. The robust construction protects internal components from environmental stress while maximizing power generation over decades.
Dual-Sided Light Absorption: The bifacial structure captures sunlight from both the front and back, increasing power gain by up to 25%. This reduces the overall Levelized Cost of Energy for the installation.
TOPCon Technology Efficiency: Tunnel Oxide Passivating Contacts minimize electron loss and degradation. This technology ensures better low-light performance and lower thermal degradation rates.
Advanced Current Collection: SMBB and Hot 2.0 technologies improve current collection efficiency. These features lead to higher module power output and enhanced reliability over time.
