Model 54HL4R-BDB | N-Type TOPCon | 108 Half-Cell Mono-crystalline | Bifacial Dual-Glass | 1500V System Voltage
The CiFi SUN 54HL4R-BDB 435W N-type TOPCon bifacial solar panel delivers high energy density in a compact footprint. This module is built around Jinko’s advanced N-type mono-crystalline cells, using HOT 2.0 TOPCon technology for strong performance. Its 435 W rated output and 21.77% efficiency help maximise yield on residential rooftops and small commercial arrays. Dual-glass bifacial construction allows energy capture from both front and rear surfaces in suitable installations. The panel operates reliably from −40 °C to +85 °C, making it suitable for diverse climates and harsh environments. A maximum system voltage of 1500 V and a 30 A series fuse rating support flexible string design for installers. With a 25-year product warranty and a 30-year linear power warranty down to 87.4% output, long-term value is protected. The all-black frame and dual-glass design also provide a clean aesthetic for projects where appearance matters.
High power and efficiency: With 435 W output and 21.77% efficiency, this module delivers strong power density on limited roof space.
Advanced N-type TOPCon cells: N-type mono-crystalline cells with HOT 2.0 technology offer low degradation and excellent long-term performance.
Bifacial dual-glass design: The bifacial glass-glass structure enables additional energy yield from reflected light at the rear side.
Robust mechanical strength: Enhanced mechanical load ratings up to 5400 Pa front and 2400 Pa rear support challenging site conditions.
Long-term warranty protection: A 25-year product warranty and 30-year linear power warranty safeguard your investment over decades.
Flexible system integration: Compatibility with 1500 V systems and standard MC4-type connectors simplifies design and installation work.
Sunlight hits the front surface of the 54HL4R-BDB module and is absorbed by N-type TOPCon cells. These high-performance mono-crystalline cells convert incoming photons into direct current electricity with strong efficiency. The bifacial design also collects reflected and diffuse light on the rear side when installed over bright or reflective surfaces. Direct current from the module flows through factory-fitted cables into a compatible string inverter or hybrid inverter. The inverter converts DC power into usable AC electricity for household loads or commercial equipment. Surplus energy can be exported to the grid or stored in batteries, depending on the system configuration used. Low temperature coefficients support better energy yield under hot operating conditions during summer days. Over decades, degradation remains low thanks to N-type cell chemistry and dual-glass encapsulation that resists moisture and stress.
N-type TOPCon cell conversion: N-type mono-crystalline cells use HOT 2.0 TOPCon passivation to reduce recombination losses. This results in higher conversion efficiency and slower power degradation over the module lifetime.
Bifacial dual-glass energy gain: The glass-glass structure exposes active cell surfaces on both sides. When mounted above bright ground or reflective rooftops, the rear side harvests additional light and boosts overall energy yield.
System integration and protection: Factory-installed MC4-compatible connectors and 4 mm² cables provide reliable DC connections. The IP68 junction box and Class II protection safeguard internal components against moisture, dust, and environmental stress.
