On reflective surfaces (gravel, concrete, white membranes), bifaciality can increase energy yield by 5-15% compared to monofacial equivalents. - **Half-cut 144-cell layout - shade resilience** - The half-cut format (144 cells vs. 72) splits the module into two electrically independent halves, reducing resistive losses and limiting the impact of partial shading on the entire string. This results in more stable output in installations with obstacles such as chimneys or antennas casting partial shadows. - **Low temperature coefficient: -0.354%/°C** - The Pmax temperature coefficient of -0.354%/°C is below the typical -0.36 to -0.40%/°C range for standard PERC modules. At Tcell = 65°C (ΔT = 40°C above STC), power loss is ~14.2% vs. ~14.4-16.0% for lower-grade modules - a measurable difference in annual energy yield. - **1500 V DC system - lower BoS costs** - Support for a 1500 V DC system voltage allows longer strings (up to ~30 modules in series at a typical Voc of ~49.5 V), reducing the number of cables, MC4 connectors, and MPPT inputs. In commercial and utility-scale PV projects, this realistically cuts BoS costs by 5-8% compared to 1000 V systems. - **30-year linear power warranty** - JA Solar guarantees a linear power degradation of no more than 0.5%/year over 30 years (>83% of Pnom after 30 years), consistent with Tier-1 standards. This is favorable for LCOE calculations compared to older models that applied a first-year degradation step (-3%) followed by 0.7%/year linear decline over 25 years. ## Cons - **Series discontinued since 2022** - The JAM72D10 400-420/MB/1500V series was manufactured between 2019 and 2022 and is officially discontinued. This means no new supply from JA Solar directly, limited availability of replacement modules in case of damage, and potentially reduced technical support and service coverage over a 15-20 year installation lifetime. - **Efficiency 20.3-20.5% - below current peers** - Peer comparables in the same 420 Wp power class achieve higher efficiencies: 20.98% (Phono Solar TWINPLUS), 21.5% (GCL-M10/54H), and 21.51% (Solarspace SS8-54HSB). The ~1-1.2 percentage point gap translates to measurable differences in energy yield per m² of roof area - critical where mounting space is limited. - **PERC (2019) - superseded by TOPCon/HJT** - Modules from 2019 based on PERC technology carry higher LID degradation (~1-2% in year one) and lower bifacial gain potential compared to newer N-type TOPCon or HJT cells available since 2023. For new projects commissioned in 2025-2026, N-type modules deliver a better LCOE at comparable purchase prices. ## About this series The JA Solar JAM72D10 400-420/MB/1500V series is designed for stable energy production under real-world operating conditions-including when the installation faces high temperatures, intermittent shading, or grid-side DC requirements. This series employs **bifacial PERC technology** and a **double glass** construction, which helps better utilize reflected light (e.g., from light-colored roofs, gravel, or concrete) and simultaneously enhances resistance to environmental factors. The **half-cell** cell configuration minimizes losses and supports higher operational reliability under partial shading, translating to more predictable yields in practice. A key advantage of this series is its **low temperature coefficient**, making power drops less noticeable on hot days compared to many standard modules. These modules operate in **1500 V** systems, facilitating longer string designs and optimizing cabling costs. This makes them an excellent choice for large commercial rooftops, PV farms, and projects where durability, stability, and cost-effectiveness are key priorities. ## Notable figures - Efficiency of 20.3% matches the \*\*PERC 400-450W\*\* median - At 202.7 W/m², this panel generates 3.5 W/m² less per unit area than \*\*PERC 400-450W\*\* median (206.2 W/m²) - Temperature coefficient of -0.35%/°C matches the \*\*PERC 400-450W\*\* median - At 25.0 kg, this panel is 3.0 kg heavier than the \*\*PERC 400-450W\*\* median (22.0 kg) - more demanding for installation crews - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface ## Questions ### Is the JA Solar JAM72D10 400-420/MB/1500V series still available for purchase? The JAM72D10 400-420/MB/1500V series has been officially discontinued by JA Solar. New units may still be found in limited quantities through distributors with existing warehouse inventory. If you are planning a new installation, consider newer JA Solar series such as the Deep Blue 3.0 line, which offers higher power output and a comparable mechanical form factor. ### What is the warranty on JA Solar JAM72D10 400-420/MB panels? JA Solar provides a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. Maximum annual power degradation is 0.5%, with at least 83% of nominal power guaranteed at the end of year 30. This is a robust warranty standard consistent with Tier 1 manufacturer benchmarks. ### What does bifacial PERC technology mean in the JAM72D10 series, and is it actually worth it? Bifacial PERC cells generate electricity from both the front and rear surfaces by capturing reflected light from the mounting substrate (albedo). With a bright surface such as gravel, concrete, or a white roofing membrane, rear-side gain can add several to over ten percent of additional yield compared to a monofacial equivalent. The double glass construction protects cells from both sides, improving moisture resistance and overall durability. For ground-mount systems and flat commercial rooftops, bifacial is a financially sound upgrade. ### How do JAM72D10 400-420/MB panels perform in hot weather - do they lose a lot of power in summer? The power temperature coefficient for this series is -0.354%/°C, meaning at a cell temperature of 70°C (a typical summer peak), power loss relative to STC is approximately 16%. This is better than many older polycrystalline modules and consistent with the upper range of quality PERC performance. The double glass construction also aids thermal management, helping to limit peak cell temperatures. ### Why does the JAM72D10 series use 144 cells, and what does the half-cut configuration mean in practice? JAM72D10 modules use 144 half-cut cells - standard PERC cells sliced in half. This layout reduces internal resistance and thermal losses while improving shade tolerance. Shading one section of the module affects only the bypass diode zone for that area rather than blocking the entire string. In practice, this translates to more predictable energy yield on rooftops with chimneys, dormers, or antennas. ### Can JAM72D10 400-420/MB modules be strung at 1500 V DC, and what are the benefits? Yes, these modules are certified for a maximum system voltage of 1500 V DC per IEC standards. Higher system voltage allows for longer strings with fewer parallel branches, reducing cable losses and Balance of System (BoS) costs. This is especially valuable in commercial and utility-scale PV projects where cable run lengths are significant and BoS optimization directly impacts overall project economics. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/20201013031530175-d2e4f3b92d36.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [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 | +50 W, cooler, +3.5 pp | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +50 W, cooler, +3.5 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +45 W, cooler, +3.3 pp | | [Luxor Solar LX-465M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-465m-182r188-108-gg) | 465 W | +50 W, cooler, +3.3 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +45 W, cooler, +3.3 pp | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +45 W, cooler, +3.2 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +45 W, cooler, +3.2 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | Cooler, lighter, +3.2 pp | | [JA Solar JAM72D10-390/MB/1500V](https://comparepv.com/panel/ja-solar-jam72d10-390-mb-1500v) | 390 W | -25 W, -1.2 pp | | [JA Solar JAM72D10-395/MB/1500V](https://comparepv.com/panel/ja-solar-jam72d10-395-mb-1500v) | 395 W | -20 W, -1.0 pp | | [JA Solar JAM72D10-400/MB/1500V](https://comparepv.com/panel/ja-solar-jam72d10-400-mb-1500v) | 400 W | -15 W, -0.8 pp | | [JA Solar JAM72D10-405/MB/1500V](https://comparepv.com/panel/ja-solar-jam72d10-405-mb-1500v) | 405 W | -10 W, -0.5 pp | | [JA Solar JAM72D10-410/TB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam72d10-410-tb-1500v) | 410 W | Cooler, -0.3 pp | | [JA Solar JAM72D10-420/MB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam72d10-420-mb-1500v) | 420 W | Very close match | | [MY Solar MS480NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms480nc-hjtpbft) | 480 W | +65 W, cooler, +1.8 pp | | [MY Solar MS475NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms475nc-hjtpbft) | 475 W | +60 W, cooler, +1.6 pp | --- Source: https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam72d10-415-mb-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.
