The JA Solar JAM54D41-460/LR with 460 W is a monofacial high-performance N-type double-glass solar module from the DeepBlue 4.0 Pro series. With a module efficiency of 23.0 %, modern N-type cell technology and robust glass-glass construction, the PV module is ideal for private and commercial photovoltaic systems with high requirements for performance, reliability and long-term energy yields.The combination of 460 W rated power, compact dimensions of 1762 × 1134 × 30 mm and a weight of only around 22 kg enables high area efficiency. At the same time, N-type technology offers low light-induced degradation, good low-light behaviour and a favourable temperature coefficient. This makes the JA Solar 460 W module ideal for durable PV systems with high self-consumption and attractive solar yields.Highlights at a glance460 W module powerWith a maximum output of 460 W, the JA Solar JAM54D41-460/LR offers high performance on a compact module area and is therefore particularly suitable for roof areas on which a high installed total output is to be achieved.23.0 % module efficiencyThe high module efficiency of 23.0 % enables efficient conversion of incident solar energy and supports high energy yields even with limited available roof area.Modern N-type technologyThe modern N-type cell technology of the DeepBlue 4.0 Pro series is designed for high energy yields, low degradation and improved behaviour in weak sunlight. This enables the module to achieve stable yields over its entire operating life.Robust double-glass constructionThe JA Solar JAM54D41-460/LR is designed as a monofacial double-glass module with 1.6 mm front glass and 1.6 mm rear glass. The glass-glass structure increases mechanical stability and protects the solar cells from environmental influences over the long term.High mechanical load capacityThe module is designed for a maximum static load of 5400 Pa on the front and 2400 Pa on the rear. This provides high resistance to mechanical loads caused by, for example, snow and wind.Long-term performance warrantyJA Solar offers a 25-year product warranty and a 30-year linear performance warranty for the module series. The stated degradation is 1 % in the first year and then 0.4 % per year. This supports long-term plannable solar yields and a high level of investment security.Efficient solar power generation for private and commercial PV systemsWith its combination of 460 W output and 23.0 % efficiency, the JA Solar JAM54D41-460/LR is ideally suited for modern residential PV systems, balcony power plants, garages, carports and commercial roof-mounted systems. The compact module size enables flexible area planning and facilitates the implementation of high-performance solar systems.Optimised for long-term solar yieldsThe temperature coefficient of maximum power is -0.290 %/°C. This means that the power loss as cell temperatures rise is comparatively low. Together with the good low-light behaviour of N-type technology, this ensures efficient energy production under different weather conditions.Technical data ModelJA Solar JAM54D41-460/LR Product seriesDeepBlue 4.0 Pro Module typeN-type double-glass, monofacial Maximum power (Pmax)460 W Module efficiency23,0 % Power tolerance0 to +3 % Open-circuit voltage (Voc)40,60 V MPP voltage (Vmp)33,68 V Short-circuit current (Isc)14,43 A MPP current (Imp)13,66 A Temperature coefficient Pmax-0,290 %/°C Temperature coefficient Voc-0,250 %/°C Temperature coefficient Isc+0,045 %/°C Number of cells108 (6 × 18) Dimensions1762 × 1134 × 30 mm Weight22 kg Front glass / rear glass1,6 mm / 1,6 mm Junction boxIP68, 3 diodes Cable cross-section4 mm² (IEC) / 12 AWG (UL) Maximum system voltage1500 V DC Maximum string fuse25 A Operating temperature-40 °C to +85 °C NOCT45 ± 2 °C Maximum static load front side5400 Pa Maximum static load rear side2400 Pa Protection classClass II Fire protection classificationUL Type 38 / Class C Product warranty25 years Linear performance warranty30 years Who is the JA Solar JAM54D41-460/LR suitable for?The JA Solar 460 W double-glass module is ideal for:Private rooftop systems with high demands on performance and durabilityBalcony power plants and mini PV systems with high-performance solar modulesCarports, garages and outbuildings with suitable mounting areaCommercial PV systems with a focus on area efficiency and long-term energy yieldsScope of delivery1x JA Solar JAM54D41-460/LR N-type double-glass solar module with 460 WFAQs about the JA Solar JAM54D41-460/LR 460 W solar moduleWhat is the efficiency of the JA Solar 460 W module?The JA Solar JAM54D41-460/LR achieves a module efficiency of 23.0 %.

JA Solar JAM54D41-LB – 460W Bifacial Glass-on-Glass Full Black (N-Type)
The JA Solar JAM54D41-LB 460W is an absolute premium solar module that combines maximum performance, exceptional durability and a sophisticated ‘Full Black’ aesthetic. Thanks to the advanced N-type cell technology this module achieves an impressive rated output of 460 watts on a standard surface area (under 2 m²), making it the perfect choice for modern homes with limited roof space.The Double-glazed construction (glass-glass) makes the module extremely resistant to environmental factors such as hail, salt or ammonia and ensures significantly higher fire safety than conventional glass-foil modules. As bifacial module, it also utilises diffuse light falling on the rear surface to generate electricity, which increases the yield, particularly on cloudy days.Key features at a glanceN-Type technology: Uses state-of-the-art cell chemistry for higher efficiency, better low-light performance and virtually zero light-induced degradation (LID).Bifacial power generation: The active module backside also converts reflected light and ambient light into energy, which can increase the total yield (depending on the mounting method) by 5-30%.Glass-to-glass construction: Two layers of tempered glass provide hermetic protection for the cells, resulting in outstanding mechanical strength and durability.Elegant all-black design: A black frame, black cells and a dark rear side ensure a uniform, unobtrusive appearance that blends perfectly into dark roofs.High efficiency: With a peak output of 460 watts in compact dimensions, it is one of the most powerful modules in its class (108 half-cells).Long-term warranty: Benefit from an industry-leading 25-year product warranty and a 30-year linear performance warranty.Areas of applicationPrivate rooftop installations: Ideal for homeowners who value maximum aesthetics (black finish) and the highest level of safety (glass-glass).Carports & patios: Thanks to its bifacial design and robust glass rear side, it is also well suited to semi-open canopies.Commercial & industry: For projects where durability and fire protection class (often better with glass-glass) are crucial.Installation & safety instructionsClamping range: When installing, ensure you adhere to the manufacturer’s specified clamping ranges on the 30 mm frame to maintain the warranty and ensure snow load capacity (5400 Pa).Glass handling: Glass-glass modules are stable, but sensitive at the corners. Never place the modules on their corners without protection during installation (use edge protection!).Cable management: Bifacial modules often have a slightly shorter junction box or cable (approx. 1.2 m). Before planning your string layout, check whether the cable length is sufficient for your planned installation method (portrait/landscape) or whether extension cables are required.

The "extra gain" here is lower than on a flat roof with a white surface, but the bifacial cell still helps to make better use of diffuse light. The main advantage of "Full Black" here, however, lies in the glass-glass stability and the appearance.Why is N-Type better than P-Type?N-Type cells have a different doping (phosphorus instead of boron). As a result, they do not suffer from the "LID effect" (Light Induced Degradation), so they do not lose any power in the first hours of operation. They also have a better temperature coefficient – so they deliver more electricity than conventional modules even on hot summer days.Will the module fit my balcony power station?Yes, absolutely. With 460 watts, it is extremely powerful and gets a lot out even at unfavourable angles. The dimensions (approx. 1.76 x 1.13 m) fit almost all standard mounts. The weight of 22 kg is very moderate for glass-glass and easy to handle.
