Full Black Bifacial Solar Panel JA Solar 460W jam54d41-460 / lb

Benefits of the solar panel JA Solar 460W Full Black Jam54D41-460 / LB

Until recently, who wanted a panel all-black to integrate it into the roof of your house, it had to give up bifacial technology and part of efficiency. The JAM54D41-460 / LBS break that commitment: unites an aesthetic Full Black well-kept n-TYPE cells of last generation, , double glass and production by both faces, in the compact format of 108 stockings cells it has become the standard of domestic self-consumption.

N-Type BYCUM + cells with up to 26% cell efficiency

JA Solar uses your cells in this series no-Bycium + with technology 16BB and architecture MBB of Media Cell, who reach a cell conversion efficiency up to 26%. At the module level, the 460 W model offers a 23.0% of efficiency, which is equivalent to some 230W per square meter deck.

The 16 Busbars distribute the current in more ways, reduce the resistive losses and they make the cell more tolerant to microfixes. In addition, JA Solar highlights a best answer with low irradiance, useful in east-west orientations, first hours of the day and cloudy days.

Bifiality in residential format

The rear glass of 1.6 mm it allows the back face of the module to capture the reflected light. With a 80% bifiality ± 10% and a 10% rear irradiance ratio, JA Solar indicates a power of 497 W, some 37 W plus by panel (around 8%). Where this advantage is more used is in high assemblies:

• Pergolas and solar porches, where the light reaches the back from the ground.
• Flat covers with inclined structures and clear surfaces.
• MARQUESINS AND ROOMS in gardens or parking areas.

In a tilted roof with coplanar mount, the rear gain will be reduced, but the module maintains the advantages of double glass in durability and aesthetics.

Performance against heat and degradation

With a pMAX temperature coefficient of -0.290%/°C, the heat power loss is contained: by way orientative, with the cell 65 ° C, the theoretical reduction would be a 11.6% regarding laboratory conditions. Technology NO-Type also presents a Very low, which is reflected in a demanding guarantee: 1% degradation the first year and 0.4% per year for 30 years, up to the 87.4% of the original power. According to the comparative curve of JA Solar, a standard module would stay at the 83.1%.

Product guarantee of 25 years

Unlike many panels that offer between 12 and 15 years, this series Full Black has 25 years of product guarantee, a very relevant coverage in a residential facility designed to last decades. On Tienda Solar we work with solar panels of first level manufacturers as JA Solar for your investment to be protected in the long term.

How to integrate JA Solar 460W Full Black in your installation

Mounting on roof and pergola

With 1762 x 1134 x 30 mm and 22 kg, each module supposes some 11 kg / m² on the cover, not including the structure. Is a comfortable format of manipulating by two operators and compatible with the majority of structures for solar panels coplanares, tile, sheet or tilt. Supports 5400 PA Front Static Charging and 2400 Pa on the back face.

Wiring and connectors

The modules incorporate 4 mm² cable with connectors QC 4.10-35 / MC4-EVO2A. The lengths are designed for each orientation: 400 mm (+) / 200 mm (-) in vertical and 1200 mm (+) / 1200 mm (-) in horizontal. The module is Class II security and admits a maximum system voltage of 1500 V DC.

Configuration of Strings: Orientation example

With a VOC 40.60 V and a vOC coefficient of -0,250%/°C, to -10 ° C the open circuit tension of each module would rise up to some 44.2 V. In a inverter residential 600 V DC of maximum voltage could theoretically connect up 13 modules by string, and even 22 modules with a inverter of 1000 V DC. These values should always be validated with the MPPT window of the equipment and the minimum temperature of the area.

Inverter and storage

The IMP of 13.66 A in STC (14.75 with a 10% rear gain) it is compatible with the entirety of inverters hybrid and of inverters networking residential, as well as many microinverters of last generation. If you want to take advantage of solar energy also at night, combine them with lithium batteries.

Frequently Asked Questions (FAQ)

1. Does a bifacial panel mean in the roof of a home?

Yes, although the rear gain depends on the assembly. In a tilted roof coping the back face receives little light, but the module continues to contribute the advantages of double glass, the technology N-Type and the 25 years of product guarantee. Where bifiality marks the difference is in pergolas, , porches and flat covers with tilted structure, where you can approach the 497 W indicating JA Solar with 10% rear irradiance.

2. What does it mean that the panel is Full Black?

That both the cells and the frame and the general aspect of the module are black, no visible silver lines. It is the preferred finish for dwellings with dark roof or slate, modern facades and pergolas in visible areas, because the panel is very discreetly integrated.

3. How many panels JA Solar 460W I need?

As a reference, 8 modules added 3,68 kWp, , 10 modules reach 4.6 kWp and 13 modules come to 5.98 kWP, occupying some 2 m² per panel. If you prefer a complete solution with inverter, structure and wiring already dimensioned, consult our solar kits.

4. Is it compatible with microinverters?

With a IMP of 13.66 A and one ISC 14.43 A in STC, it is compatible with many microinverters current, provided that its entry current also supports the increase by bifacial gain (ISC 15.58 A with 10% rear irradiance). Always review the tab of the microinverter before choosing.

5. What guarantee does the JA Solar JAM54D41-460 / LBS?

JA Solar offers 25 years of product guarantee facing manufacturing defects and 30 years of linear power guarantee, with a maximum degradation of 1% the first year and from 0.4% annually, which ensures at least a 87.4% of the initial power in the year 30.
