JA Solar JAM54D41-440/LB — 440W Bifacial TOPCon Module

High-efficiency solar power in a compact footprint. This 440 W bifacial, glass-glass module delivers premium efficiency and rugged durability for cabins, off-grid homes, RVs, fifth-wheels, and mobile power systems looking to maximize production with fewer panels.

Why you’ll love this

High output — 440 W of rated power with 22.0% efficiency helps reduce the total number of panels needed.
Bifacial gain — captures reflected light from snow, rooftops, decks, and bright ground surfaces for additional energy harvest.
Glass-glass durability — rugged dual-glass construction offers excellent long-term reliability in harsh weather and mobile applications.
Excellent low-light response — strong morning, evening, and cloudy-day performance helps extend charging hours.

Built for cabins, RVs & mobile rigs

Fewer panels required: higher output reduces roof space requirements for cabins and RVs.
Mobile-friendly durability: glass-glass construction stands up well to vibration, hail, and heavy snow.
Better real-world production: strong low-light characteristics help maintain charging performance throughout the day.
Bifacial advantage: ideal for reflective environments like snow, white roofs, gravel, and elevated ground mounts.
Easy integration: compatible with modern MPPT charge controllers and 12V, 24V, and 48V battery systems.

Controller & Wiring Notes

Use an MPPT controller sized appropriately for the panel's Voc and Isc.
Typical controller sizing: approximately 40A for 12V systems or 20A for 24V systems per panel.
Integrated MC4-compatible connectors simplify series and parallel array wiring.
Use properly sized fuses, breakers, and outdoor-rated solar cable for safe installation.

Fit & mounting tips

Panel dimensions are approximately 69.3" × 44.6" × 1.18". Always verify roof clearances around vents, fans, air conditioners, and racks before ordering.

For RV and trailer applications, leave an airflow gap beneath the panel to reduce operating temperatures and improve performance.
