The glass-glass encapsulation enhances mechanical durability and minimizes moisture ingress. - **N-type cells - low LID degradation** - N-type cell technology eliminates Light-Induced Degradation (LID) typical of P-type PERC cells, resulting in higher actual output in the first years of operation. Annual degradation for N-type is typically \<0.45%/yr vs ~0.55%/yr for PERC - over a 30-year lifespan this translates to approximately 3 percentage points more retained power. - **1500 V DC system compatibility** - The 1500 V system voltage enables longer string configurations (up to ~28 modules/string with a typical 1500 V inverter), directly reducing BoS costs - fewer cables, fewer combiners, and lower resistive losses. A critical feature for utility-scale PV farms and commercial installations above 100 kWp. - **30-year power warranty, BNEF Tier-1 manufacturer** - The series carries a 30-year linear power warranty and a 12-year product warranty. JA Solar maintains continuous BNEF Tier-1 status (confirmed on the Q2 2026 list), ensuring bankability for project financing and reducing warranty recourse risk for investors and lenders. - **Half-cut + multi-busbar: shade tolerance** - Half-cut cell splitting reduces resistive losses (I²R) and limits the impact of partial shading on the full string - each half-row operates independently. Multi-busbar design shortens current path length and reduces the risk of degradation from microcracks. ## Cons - **Discontinued series (since 2022)** - The JAM72D10 405-425/TB/1500V was discontinued in 2022 after only two years of production (2020-2022). This limits availability of replacement modules for system expansions, raises the risk of power mismatch if a single module needs replacing, and may complicate warranty service fulfillment for the identical product. - **Efficiency below current peer comparables** - Maximum series efficiency is 20.8%, while direct competitors in the same segment achieve: Hyundai DG G12 PERC Shingled - 21.4%, Trina Vertex S - 21.3%, Tongwei TERRA 5K - 21.4%. The 0.5-0.6 pp gap translates to a larger required roof or land area to achieve the same peak power output. ## About this series The JA Solar JAM72D10 405-425/TB/1500V series are bifacial glass-glass modules, designed for stable energy production not only from the front side but also from the rear side via reflected radiation-truly enhancing yield in ground-mounted installations, membrane-covered roofs, or with well-designed structures. The use of N-type monocrystalline cells translates to lower susceptibility to degradation and better performance consistency over time, which is crucial where predictable energy balance over years is key. The half-cell with multi-busbar construction helps minimize losses due to partial shading and supports higher module reliability in challenging operating conditions. A key advantage of this series is its compatibility with 1500 V systems, facilitating longer string designs and optimizing BOS components in larger installations. This is an excellent choice for PV farms, commercial projects, and investors seeking the benefits of bifacial technology without compromising on durability and parameter stability. ## Notable figures - At 20.8% efficiency, this panel is 1.1pp below the \*\*N-type 400-450W\*\* median of 21.9% - 207.6 W/m² power density is 10.8 W/m² below \*\*N-type 400-450W\*\* median (218.4 W/m²) - requires larger installation area - -0.31%/°C temperature coefficient - 0.02pp worse than \*\*N-type 400-450W\*\* median (-0.29%/°C), expect higher hot weather losses - At 25.0 kg (3.0 kg above \*\*N-type 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - Bifacial design (75% factor) captures reflected light - adds 4-11% yield on ground-mount or white roof ## Questions ### What is the warranty on JA Solar JAM72D10 405-425/TB/1500V panels? JA Solar offers a 12-year product warranty on the JAM72D10 405-425/TB/1500V series. The power output warranty extends to 30 years, guaranteeing that panels retain a specified percentage of their nominal power over three decades. This is one of the longer warranty standards in the bifacial module segment and reflects JA Solar's confidence in the long-term durability of the glass-glass construction. ### Do the JAM72D10 405-425/TB/1500V bifacial panels actually generate more energy? Yes, provided the installation conditions are right. The bifacial modules in the JAM72D10 series capture additional energy by converting reflected irradiance on the rear side of the panel. Real gains depend on ground albedo - light-colored gravel or a white roofing membrane yield better results than dark soil. In practice, rear-side gains can range from a few percent up to roughly 25% additional output over the front side alone. ### What are N-type cells and why do they matter in the JAM72D10 405-425/TB/1500V panels? The N-type cells used in this series are phosphorus-doped monocrystalline silicon wafers, making them less susceptible to light-induced degradation (LID) and heat-induced degradation than boron-doped P-type cells. In practice, this means more stable energy production over time and a lower annual degradation rate compared to P-type PERC modules - a key advantage for investors expecting predictable output throughout the full 30-year power warranty. ### What types of installations are the JA Solar JAM72D10 405-425/TB/1500V panels best suited for? This series is particularly well suited to utility-scale solar farms and large commercial installations. The 1500 V system voltage compatibility allows designers to configure longer strings and reduce BoS costs through less DC cabling and fewer connections. The bifacial design and sealed glass-glass construction excel in ground-mounted systems with high ground albedo. With up to 425 Wp from N-type cells, the series delivers high power density per square meter. ### What are the advantages of the JAM72D10 405-425/TB/1500V panels being rated for 1500 V systems? Support for system voltages up to 1500 V DC lets designers string more modules together than in standard 1000 V systems. The result is fewer strings, less DC cabling, and lower BoS component costs per watt of installed capacity. This advantage is most significant in large utility-scale PV farms, where lower BoS expenditure directly improves the LCOE of the entire project. ### Is the JA Solar JAM72D10 405-425/TB/1500V series still available for purchase? The JAM72D10 405-425/TB/1500V series has been discontinued by JA Solar and is no longer actively stocked through standard distribution channels. Limited inventory may still be available at select distributors, but relying on it for new project planning is not advisable. For installations requiring similar performance characteristics, currently manufactured JA Solar N-type series modules are the recommended alternative. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/20200619044346382-9b2fcfe5c185.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +50 W, +3.2 pp, +10 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +40 W, lighter, +3.0 pp | | [JA Solar JAT54S40-475/LR](https://comparepv.com/panel/ja-solar-jat54s40-475-lr) | 475 W | +50 W, lighter, +3.0 pp | | [Tongwei TWMNH-48HW475](https://comparepv.com/panel/tongwei-solar-twmnh-48hw475) | 475 W | +50 W, cooler, +3.0 pp | | [Astronergy CHSM48RN(DG)/F-BH-475](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-f-bh-475) | 475 W | +50 W, cooler, +3.0 pp | | [AIKO AIKO-A475-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a475-mce54mw) | 475 W | +50 W, cooler, +3.0 pp | | [AIKO AIKO-A475-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a475-mah54mw) | 475 W | +50 W, cooler, +3.0 pp | | [JA Solar JAM72D10-390/MB/1500V](https://comparepv.com/panel/ja-solar-jam72d10-390-mb-1500v) | 390 W | -35 W, hotter, -1.7 pp | | [JA Solar JAM72D10-395/MB/1500V](https://comparepv.com/panel/ja-solar-jam72d10-395-mb-1500v) | 395 W | -30 W, hotter, -1.5 pp | | [JA Solar JAM72D10-400/MB/1500V](https://comparepv.com/panel/ja-solar-jam72d10-400-mb-1500v) | 400 W | -25 W, hotter, -1.3 pp | | [JA Solar JAM72D10-405/MB/1500V](https://comparepv.com/panel/ja-solar-jam72d10-405-mb-1500v) | 405 W | -20 W, hotter, -1.0 pp | | [JA Solar JAM72D10-410/TB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam72d10-410-tb-1500v) | 410 W | -15 W, -0.8 pp | | [JA Solar JAM72D10-415/MB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam72d10-415-mb-1500v) | 415 W | -10 W, hotter, -0.5 pp | | [JA Solar JAM72D10-420/MB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam72d10-420-mb-1500v) | 420 W | Hotter, -0.3 pp | | [MY Solar MS480NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms480nc-hjtpbft) | 480 W | +55 W, cooler, +1.3 pp | | [MY Solar MS475NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms475nc-hjtpbft) | 475 W | +50 W, cooler, +1.1 pp | --- Source: https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam72d10-425-tb-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.
