JA Solar JAM54-D41 440W Bifacial Solar Panel

About This Product

The JA Solar JAM54-D41 440W Bifacial Solar Panel is a 440W bifacial monocrystalline module from JA Solar’s JAM54D41 series. It uses 108 half-cell construction with N-type TOPCon cell technology and a bifacial design that can generate power from both the front and rear sides of the module when installed over a suitable reflective surface. The panel features a black frame, transparent rear construction, 16-busbar cell design, and genuine MC4-EVO2 connectors. Its 1500V DC system-voltage capability makes it suitable for properly engineered residential and commercial PV systems.

Who This Product Suits

The JA Solar JAM54-D41 440W Bifacial Solar Panel suits residential and commercial installers looking for a high-output N-type module in a compact 108 half-cell format. It is particularly useful where bifacial energy collection can be taken advantage of, such as elevated arrays, light-colored roofing, carports, and other installations with useful rear-side irradiance. System designers should confirm string voltage, inverter compatibility, racking requirements, and applicable NEC requirements before installation.

Specifications Explained

• 440W rated output: Provides 440 watts of nameplate DC power under standard test conditions.
• N-type TOPCon technology: Uses N-type passivated-contact cells designed for strong electrical performance and low long-term degradation.
• Bifacial construction: Allows the rear side of the module to contribute additional generation when sufficient reflected or rear-side light is available.
• 108 half-cell design: Uses electrically divided cells to support efficient current flow and practical module-level performance.
• 16-busbar design: Uses multiple cell interconnections to collect and transfer current across the module.
• 1500V DC maximum system voltage: Supports appropriately designed PV strings and equipment rated for 1500V DC operation.
• MC4-EVO2 connectors: Factory leads use genuine MC4-EVO2 connectors for industry-standard PV connections.
• Long-term coverage: Backed by a 25-year manufacturer product warranty and a 30-year linear performance warranty with stated annual degradation of 0.40% over 30 years.

Summary

The JA Solar JAM54-D41 440W Bifacial Solar Panel combines 440W output, N-type TOPCon cells, bifacial construction, 108 half-cells, and a 1500V DC system rating. For US installers, it is a practical option for residential or commercial arrays where module efficiency, bifacial capability, and long-term performance coverage are important. Final system design should always account for inverter limits, string sizing, racking, rapid-shutdown requirements where applicable, and current NEC requirements.
