Standard PERC panels typically suffer 1–2% LID loss in year one; in this series that mechanism is effectively eliminated, resulting in measurably higher energy yield throughout the module's service life. - **Bifacial – additional rear-side energy harvest** - The glass-glass bifacial construction (JAM72D30 LB) captures reflected irradiance from the mounting surface. At albedo values of 0.2–0.4 (light-colored gravel, concrete, snow) bifacial gain realistically ranges from 5–15%, equivalent to an effective 30–87 W of additional output on top of the 580 W front-side STC rating. - **Half-cut 144-cell layout + MBB busbars** - Splitting cells in half reduces operating current by 50%, cutting resistive losses (P = I²R) and improving shade tolerance. Multi Busbar (MBB) design shortens current paths and reduces thermomechanical stress on the cell, contributing to longer-term module reliability. - **30-year linear power warranty** - JA Solar backs this series with a 30-year linear power warranty — one of the longest in the PERC segment. For bank-financed commercial and prosumer installations, this underpins higher loan-to-value ratios and provides the production forecast certainty required in DCF project models. - **BNEF Tier-1 manufacturer, 100 GW annual capacity** - JA Solar holds BNEF Tier-1 bankable status (confirmed Q2 2026) with 100 GW annual production capacity. This ensures eligibility for institutionally financed projects and provides supply chain stability and warranty service continuity across the full 30-year operational horizon. ## Cons - **Lower efficiency vs. N-type peers** - Peak module efficiency tops out at 21.9%, while direct peer comparables — Emmvee Titanium Duo/Clear and ZNShine ZXM7-UHLD144 — reach 22.44–22.45% at the same 580 W power class. The ~0.55 percentage-point gap (~2.5% relative) translates to roughly one additional module required per ~40 modules in roof-constrained installations. - **Temperature coefficient -0.35%/°C (PERC)** - PERC technology yields a Pmax temperature coefficient of -0.35%/°C, versus -0.30 to -0.32%/°C typical of N-type TOPCon modules. At a representative module temperature of 60°C (∆T = 35°C above STC), that differential means approximately 0.10–0.17% less power output versus N-type alternatives — accumulating to tens of kWh per year in a 10 kWp system. - **12-year product warranty** - The workmanship warranty covers 12 years, while several premium competitors in the same power class — including LONGi Hi-MO 6 and Trina Vertex S+ — offer 15-year product warranties. For commercial projects with 15–20 year investment cycles, a shorter product warranty may reduce project scoring with insurers and lenders. ## About this series The JA Solar DeepBlue 3.0 Pro LB series is based on high-efficiency M10 cells, which represent an optimal solution for maximizing energy yields while maintaining stable system costs. The innovation of this line is based on the use of **gallium-doped cell technology**, which effectively eliminates the problem of light-induced degradation (LID) and guarantees the long-term performance of the modules. Thanks to the use of **half-cut structure and MBB busbars**, the panels are characterized by lower resistive losses and better operation in partial shading conditions. This series solves the key problem of limited installation space by offering **above-average power density**, which allows for generating more electricity from a smaller roof area. It is a solution dedicated primarily to demanding prosumer and commercial installations, where a low LCOE and reliability in difficult weather conditions matter. Compared to standard modules, the DeepBlue 3.0 Pro LB series stands out with **optimized temperature parameters**, which translates into real gains on hot days. This is a proposal for investors focusing on proven technology that combines innovative design with exceptional resistance to aging effects, ensuring safe operation for decades. ## Notable figures - At 21.5% efficiency, this panel is on par with typical \*\*PERC 550-600W\*\* modules - At 215.4 W/m² power density, roof space requirements are typical for \*\*PERC 550-600W\*\* panels - At -0.35%/°C, hot weather performance is typical for \*\*PERC 550-600W\*\* panels - Weight of 32.5 kg is 1.7 kg above \*\*PERC 550-600W\*\* median (30.8 kg) - verify structural support - 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces ## Questions ### What warranty does the JA Solar DeepBlue 3.0 Pro LB Series come with? The DeepBlue 3.0 Pro LB Series includes a 12-year product warranty covering manufacturing defects and a 30-year linear power output warranty. As a Bloomberg NEF Tier 1 manufacturer, JA Solar maintains strong warranty service infrastructure in Europe. The 30-year power guarantee puts this series among the best-covered modules available on the market today. ### Are the DeepBlue 3.0 Pro LB panels bifacial, and does it pay off in real-world conditions? Yes, the LB designation indicates bifacial modules that harvest energy from both the front and rear sides by capturing light reflected from the ground surface. In mid-European climates, rear-side gain typically ranges from 5 to 15%, depending on albedo and tilt angle. The highest gains are achieved on bright surfaces such as light-colored gravel, concrete, or snow, and with sufficient clearance between the module and the mounting surface. ### What is gallium doping and why does JA Solar use it in the DeepBlue 3.0 Pro LB? Conventional boron-doped PERC cells are susceptible to light-induced degradation (LID), which can reduce output by 2–3% in the first year of operation. Replacing boron with gallium as the dopant eliminates this degradation mechanism. As a result, DeepBlue 3.0 Pro LB panels operate at or very close to their rated 580 Wp from day one and deliver more lifetime energy than standard PERC modules without this improvement. ### What is the maximum power output of the JA Solar DeepBlue 3.0 Pro LB, and how many panels are needed for a 10 kWp system? The top variant in this series reaches 580 Wp under Standard Test Conditions (STC). A 10 kWp system therefore requires approximately 18 modules. The high power density enabled by M10 half-cut cells means you can fit more kilowatts on the same roof area compared to older, lower-efficiency series, which is a key advantage for installations with limited roof space. ### Do the DeepBlue 3.0 Pro LB panels perform well on hot summer days? Yes. The DeepBlue 3.0 Pro LB series features optimized temperature coefficients, with a Pmax temperature coefficient of approximately -0.35%/°C, which is among the better figures for PERC-based modules. At an operating temperature of 60°C, these panels lose less power than older designs with higher coefficients. In practice, this translates to measurably higher energy yield during peak summer months. ### How does the JA Solar DeepBlue 3.0 Pro LB differ from standard PERC modules without MBB and half-cut technology? Conventional full-cell PERC modules with fewer busbars have higher resistive losses and greater sensitivity to partial shading. The DeepBlue 3.0 Pro LB combines half-cut cells, which halve the current per circuit and reduce thermal losses, with MBB technology that shortens the current path to the busbars. The result is higher overall efficiency, better output under cloudy conditions, and improved resistance to microcracks throughout the module's service life. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/20240112032829776-5583bbc0cb08.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.1 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 16 kg lighter, +2.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.9 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.9 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +2.8 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.7 pp | | [JA Solar JAM72D30-555/LB/1500V](https://comparepv.com/panel/ja-solar-jam72d30-555-lb-1500v) | 555 W | -15 W, -0.5 pp | | [JA Solar JAM72D30-560/LB/1500V](https://comparepv.com/panel/ja-solar-jam72d30-560-lb-1500v) | 560 W | -10 W, -0.3 pp | | [JA Solar JAM72D30-565/LB/1500V](https://comparepv.com/panel/ja-solar-jam72d30-565-lb-1500v) | 565 W | Very close match | | [JA Solar JAM72D30-575/LB/1500V](https://comparepv.com/panel/ja-solar-jam72d30-575-lb-1500v) | 575 W | Very close match | | [JA Solar JAM72D30-580/LB/1500V](https://comparepv.com/panel/ja-solar-jam72d30-580-lb-1500v) | 580 W | +10 W, +0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +80 W, cooler, +3.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +110 W, cooler, +3.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +105 W, cooler, +3.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +75 W, cooler, +3.5 pp | --- Source: https://comparepv.com/panel/ja-solar-jam72d30-570-lb-1500v Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
