IEC 61215 mechanical load tests confirm that glass-glass modules offer meaningfully higher structural durability than standard backsheet panels, resulting in a longer service life. - **Bifacial cells - higher annual energy yield** - The module harvests energy from both the front and rear surfaces. Per the manufacturer's datasheet and independent field measurements, bifacial PERC glass-glass modules typically deliver 3-15% more energy than their monofacial equivalents at ground albedo ≥20%. The gain is most pronounced on white roofing membranes, light-colored gravel, and high-albedo ground surfaces. - **Half-cut PERC - shade tolerance** - Splitting cells in half reduces operating current by ~50%, lowering resistive I²R losses and minimizing the impact of partial shading (chimneys, antennas, trees) on full-string output. The power temperature coefficient Pmpp = -0.354%/°C ranks the series in the upper tier of PERC modules for thermal performance. - **1500 V DC system compatibility** - A rated system voltage of 1500 V DC enables longer string configurations (more modules per string), reducing the number of inverters, DC cable runs, and overall BoS costs by an estimated 5-10% compared to 1000 V systems in commercial rooftop and utility-scale PV projects. - **BNEF Tier-1 manufacturer, 30-year power warranty** - JA Solar has maintained BNEF Tier-1 bankable status continuously for over a decade and exceeded 100 GW annual manufacturing capacity in the Q1 2025 ranking, lending credibility to its warranty commitments. The 30-year linear power warranty guaranteeing ≥87.4% output after that period exceeds the 25-year standard offered by most peers. ## Cons - **Discontinued series (since 2023)** - The JAM60D10 series was manufactured between 2020 and 2023 and is no longer in active production. This results in limited new-module availability on the open market, risk of no compatible replacements in the event of failure, and difficulty expanding an existing installation with identical panels in the future. - **P-type PERC - older-generation cell technology** - Newer series from market leaders (Jinko Tiger Neo, LONGi Hi-MO 6) use N-type TOPCon or HJT cells, which exhibit lower LID degradation rates and better performance under high-temperature conditions. By choosing this series, the investor forgoes the advantages of N-type technology that became the premium industry standard after 2023. - **Efficiency below segment leaders** - The series' peak efficiency is 20.4% (350 Wp variant), while direct peer comparables achieve: Jinko JS Solar 120 - 20.7%, YS Solar YS SM-90 - 21.0%. The 0.3-0.6 percentage-point gap translates to needing 1-2 additional modules per 10 kWp system to reach the same nameplate power on the same roof area. ## About this series The JA Solar JAM60D10 325-350/MB/1500V series is designed to maximize energy output on limited rooftop space, prioritizing reliability without compromise. These monocrystalline modules feature a **glass-glass** construction, enabling better resistance to micro-cracks, moisture, and aging compared to many standard film-based panels. The implementation of **bifacial** technology allows capturing additional reflected light energy-particularly on light-colored roofs, membranes, and high-albedo grounds, significantly improving annual yield. This series utilizes **half-cut** cell architecture and **PERC** technology, which helps minimize resistive losses and maintain performance under partial shading (e.g., from chimneys, antennas, or trees). An additional advantage is the **1500 V system**, facilitating longer string designs and reducing losses in commercial installations. This makes it an excellent choice for homes, businesses, and utility-scale PV farms, where stable yield and durable module construction are essential. ## Notable figures - At 19.5% efficiency, this panel is on par with typical \*\*PERC 0-400W\*\* modules - At 194.8 W/m² power density, roof space requirements are typical for \*\*PERC 0-400W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 0-400W\*\* median - At 22.0 kg, this panel is 1.5 kg heavier than the \*\*PERC 0-400W\*\* median (20.5 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 JAM60D10 325-350/MB/1500V series still available for purchase? The JAM60D10 325-350/MB/1500V series has been discontinued by JA Solar. New units may occasionally be found at distributors with remaining warehouse stock, but the series is no longer in serial production. If you are planning a new installation, consider current JA Solar series with higher power output and newer cell technology. ### What warranty does the JA Solar JAM60D10 350W panel carry, and what does it cover? JA Solar provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty. After 30 years, the panel should retain at least 80.7% of its rated power. These are standard Tier 1 terms from JA Solar. Always keep your purchase invoice, as the warranty is typically tied to the installation date. ### Does the bifacial design of the JAM60D10 actually improve energy yield on a typical rooftop? Yes, though the gain depends on the surface below. On light-colored membranes, white gravel ballast, or high-albedo ground, the rear side of the panel can contribute 5 to 15% additional annual yield. On dark bitumen or in tight roof-flush mounts with no rear clearance, the gain is minimal. The glass-glass construction of the JAM60D10 is well suited to bifacial operation and provides superior moisture resistance compared to conventional backsheet modules. ### How do the half-cut PERC cells in the JAM60D10 handle partial shading from a chimney or antenna? The half-cut architecture splits each cell into two halves, reducing the current per half-cell and lowering resistive losses. Under partial shading from a chimney or antenna, the unshaded portion of the module continues producing power with fewer losses than a standard full-cell panel. The PERC technology further boosts cell efficiency, giving the JAM60D10 350W a module efficiency of approximately 20.4%. ### Does the 1500 V system voltage on the JAM60D10 require a special inverter, and is it suitable for residential use? The 1500 V DC system voltage is designed primarily for commercial installations and solar farms, where it enables longer strings and reduces BoS wiring costs. For residential use, a standard 1000 V inverter is fully compatible with this series. Before purchasing, confirm that your inverter's MPPT input voltage range matches the planned string configuration. ### How heavy is the JA Solar JAM60D10 350W panel, and can it be installed on a standard pitched roof? The JAM60D10 350W weighs approximately 22 kg and measures 1711×1005×30 mm. The glass-glass construction is somewhat heavier than conventional backsheet modules, which should be factored into roof load calculations. Installation on standard pitched roofs is feasible, but a structural check by your installer is recommended, especially for older roof trusses. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/20201013025305231-be9151547a4e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Cooler, lighter, +3.8 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +3.8 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +3.6 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +3.6 pp | | [Heckert Solar ZEUS 3.2 285WP FullBlack](https://comparepv.com/panel/heckert-solar-zeus-3-2-285wp-fullblack) | 285 W | Cooler, lighter, +3.6 pp | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | -50 W, lighter, +3.5 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -35 W, lighter, +3.5 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -15 W, lighter, +3.5 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +3.5 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | +25 W, lighter, +3.5 pp | | [JA Solar JAM60D10-320/MB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam60d10-320-mb-1500v) | 320 W | -15 W, -0.9 pp | | [JA Solar JAM60D10-325/MB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam60d10-325-mb-1500v) | 325 W | -10 W, -0.6 pp | | [JA Solar JAM60D10-330/MB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam60d10-330-mb-1500v) | 330 W | -0.3 pp | | [JA Solar JAM60D10-340/TB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam60d10-340-tb-1500v) | 340 W | Cooler, +0.3 pp | | [JA Solar JAM60D10-345/TB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam60d10-345-tb-1500v) | 345 W | +10 W, cooler, +0.6 pp | | [JA Solar JAM60D10-350/TB/1500V](https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam60d10-350-tb-1500v) | 350 W | +15 W, cooler, +0.9 pp | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +105 W, cooler, +3.4 pp | --- Source: https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam60d10-335-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.
