JA Solar 610W N-type Bifacial Double Glass Solar Panel – Deep Blue 4.0 Pro

610 W Peak Power n-Type Bycium+ Cell Bifacial Double Glass 23.1% Module Efficiency Up to 26% Cell Efficiency 1500 V DC System Voltage 30-Year Linear Power Warranty

The JA Solar JAM72D40-610/LB is a 610 W n-type bifacial double-glass solar module from the Deep Blue 4.0 Pro series — one of JA Solar's highest-performance commercial and utility-scale panels. Built around n-type Bycium+ cells with 16 busbars (16BB) and Multi-Busbar (MBB) half-cell technology, the module achieves up to 26% cell conversion efficiency and a 23.1% module efficiency at STC. The bifacial double-glass construction captures additional energy from reflected rear irradiance — rated at 80% ± 5% bifaciality — while delivering significantly lower Light-Induced Degradation (LID) than conventional p-type modules. With a maximum system voltage of 1500 V DC, MC4-EVO2A connectors and a robust IP68 junction box, the JAM72D40-610/LB is engineered for large commercial rooftops, ground-mount arrays and utility installations.

Key Features & Technology

n-Type Bycium+ Cells — Up to 26% Cell Efficiency

JA Solar's proprietary n-type Bycium+ technology combines a boron-doped n-type silicon base with tunnel oxide passivated contact (TOPCon-derived) architecture and 16 busbars (16BB) MBB half-cell layout. The result is significantly lower recombination losses, delivering cell efficiencies of up to 26% — well above conventional PERC p-type cells.

Bifacial Double Glass — Harvest Rear Irradiance

Both front and rear surfaces generate power. The 80% ± 5% bifaciality factor means the rear face produces up to 80% of the front-face output under equivalent irradiance. Combined with the 2.0 mm / 2.0 mm double-glass construction, the module captures reflected light from rooftops, ground albedo or snow — meaningfully increasing annual energy yield versus monofacial panels.

Very Low LID — n-Type Advantage

n-type silicon is inherently resistant to light-induced degradation (LID) caused by boron-oxygen complexes — a common loss mechanism in p-type PERC modules. The JAM72D40 LB is rated with very low LID, preserving more of its rated power output immediately after commissioning and throughout its operating life.

Superior Temperature Coefficient

At -0.290%/°C (Pmax), the JAM72D40-610/LB loses less power in hot weather than standard PERC modules (typically -0.35%/°C). On a 60°C roof surface this equates to several percentage points of additional output — a meaningful advantage in warm UK summers and critical for hot-climate deployments.

Better Low-Irradiance Response

n-type cells maintain higher relative efficiency in diffuse and overcast conditions, which is particularly valuable in the UK climate. The module continues to generate meaningful power even when irradiance drops well below the STC 1000 W/m² test condition — improving overall annual yield.

1500 V System Voltage — Fewer Strings, Lower BOS Cost

The 1500 V DC maximum system voltage allows longer strings with fewer parallel branches, reducing cable runs, combiner boxes and associated balance-of-system costs. This is the preferred configuration for commercial and utility-scale projects using modern 1500 V string inverters.

IP68 Junction Box & MC4-EVO2A Connectors

The IP68-rated 3-diode junction box provides robust moisture and dust ingress protection even in permanent outdoor immersion conditions. MC4-EVO2A connectors ensure secure, reliable connections compatible with the industry-standard MC4 ecosystem and rated for the full 1500 V system voltage.

30-Year Linear Power Warranty with Enhanced Retention

1% first-year degradation, then just 0.4% per year for 30 years — guaranteeing a minimum 87.4% of rated power at year 30, compared to 83.1% for standard module linear warranties. Combined with a 12-year product warranty, this represents best-in-class long-term performance assurance.

Frequently Asked Questions

What is the difference between this n-type module and a standard p-type PERC panel?

The JAM72D40 LB uses n-type Bycium+ silicon, which is inherently free from the boron-oxygen defects responsible for Light-Induced Degradation (LID) in p-type cells. This means lower first-year power loss, better temperature coefficient (-0.290%/°C vs ~-0.35% for PERC), superior low-irradiance performance, and higher cell efficiency (up to 26%). The 16BB MBB half-cell layout further reduces resistive losses and improves shading tolerance compared to conventional full-cell p-type modules.

How much extra energy does the bifacial design produce?

Real-world bifacial gain depends on installation conditions — ground albedo, mounting height, tilt angle and whether there are obstructions blocking rear irradiance. Typically, bifacial modules on open ground-mount systems with light-coloured ground cover yield 5–15% additional energy versus equivalent monofacial panels. On flat white membrane rooftops gains of 3–8% are commonly achieved. JA Solar's datasheet uses a 10% bifacial irradiance ratio to calculate NOCT bifacial output — at 610 W nominal, this yields a 659 W effective NOCT output.

Is the 610 W variant compatible with standard commercial inverters and mounting systems?

Yes. The 1500 V DC maximum system voltage is the current industry standard for commercial and utility inverters from Huawei, SMA, Sungrow, Fronius and others. The module uses MC4-EVO2A connectors, cross-compatible with the standard MC4 ecosystem. At 2333 × 1134 mm it fits most commercial mounting rail systems — confirm with your racking manufacturer for exact clamp positions and load ratings, noting the 5400 Pa front / 2400 Pa rear maximum static load ratings.

What does the 30-year linear warranty cover?

JA Solar guarantees ≥ 99% of rated Pmax after year 1 (i.e. maximum 1% first-year degradation), then ≤ 0.4% annual degradation for years 2 through 30, resulting in a guaranteed minimum output of 87.4% of rated power at year 30. This is meaningfully better than the standard industry warranty (typically 0.55%/year = 83.1% at year 30). The separate 12-year product warranty covers manufacturing defects and workmanship.

What are the double-glass construction advantages over a glass-backsheet module?

Double-glass modules replace the polymer backsheet with a second pane of glass, providing superior resistance to potential-induced degradation (PID), UV degradation and moisture ingress. The glass-glass sandwich eliminates the main UV degradation pathway, contributing to the low annual degradation rate. It also means no flammable backsheet material — the UL Type 29 / Class C fire rating reflects this. The trade-off is slightly higher weight (32.5 kg vs ~25 kg for glass-backsheet panels of similar size), which should be accounted for in roof load calculations.
