Half-cut cells combined with Multi-Busbar (MBB) design significantly reduce resistive losses and minimize microcracks. - **20.9-21.9% efficiency - top of PERC M10 segment** - The upper efficiency of 21.9% matches Longi Hi-MO 5m (G2) and Suntech Ultra V (both at 21.9%), exceeding GCL M10/72H (21.87%), placing DeepBlue 3.0 Pro at the top of its direct peer-comparable group. The 540-565 Wp power range offers flexibility for both residential prosumer installations and utility-scale solar farms. - **30-year linear power warranty** - JA Solar guarantees a linear performance curve over 30 years - 5 years longer than the 25-year standard prevailing in the PERC segment (e.g., Trina Vertex S+, Canadian Solar HiKu6). The extended warranty directly lowers LCOE for investments with a horizon beyond 25 years and facilitates project financing. - **BNEF Tier-1 (Q1 2026) - world's 3rd largest manufacturer** - JA Solar has maintained continuous BNEF Tier-1 status and reached ~100 GW/year production capacity in 2025 (3rd globally behind LONGi and Jinko Solar). Tier-1 status confirms module acceptance by at least six independent banks in non-recourse financed projects - a critical criterion for commercial project financing. - **Gallium-doped wafers reduce LID** - M10 silicon wafers doped with gallium eliminate the boron-oxygen light-induced degradation (LID) inherent in standard boron-based P-type cells. First-year degradation is ~2% and subsequent annual degradation ~0.5%/yr - significantly lower than non-doped P-type cells and consistent with the manufacturer's datasheet claims. ## Cons - **P-type PERC: inferior temperature coefficient** - The Pmax temperature coefficient is -0.35%/°C, compared to ~-0.30%/°C for modern N-type TOPCon modules (JA DeepBlue 4.0 Pro, Longi Hi-MO 6). A 0.05%/°C difference at 35°C above STC (typical summer conditions in Central Europe) yields ~1.75% lower instantaneous output. Annual PERC degradation of ~0.45-0.55%/yr vs. TOPCon \<0.40%/yr accumulates to 1.5-4.5 percentage points of residual power difference over 30 years. - **Technically superseded by DeepBlue 4.0 Pro** - The DeepBlue 3.0 Pro series (launched June 2021, SNEC) is technically superseded by the same manufacturer's DeepBlue 4.0 Pro (N-type TOPCon, efficiency up to 23.3% vs. max 21.9% for the 3.0 Pro). For new projects planned beyond 2025, selecting the newer N-type architecture may be economically more justified despite a higher upfront cost per Wp. ## About this series The DeepBlue 3.0 Pro series is an advanced solution based on M10 silicon wafers, which set a new standard for efficiency in modern photovoltaic installations. The use of **Half-Cut cell technology** in combination with multi-busbar architecture significantly reduces resistive losses and improves the resistance of modules to micro-cracks. As a result, these panels perform excellently even in demanding lighting conditions, which directly translates into higher energy yields from every square meter of surface area. What distinguishes this series from the competition is the precise optimization of dimensions for logistics and installation, which effectively lowers balance-of-system (BOS) costs and shortens investment implementation time. **High module efficiency** goes hand in hand with excellent mechanical stability, making this series an ideal choice for both residential rooftop micro-installations and large-scale solar farms. DeepBlue 3.0 Pro effectively solves the problem of limited installation space, offering investors **maximization of unit power** while maintaining cell longevity. By choosing these panels, users gain the certainty of stable operation for decades, as confirmed by rigorous endurance tests and a **low power degradation coefficient** over time. This is a reliable foundation for modern prosumer and commercial energy sectors. ## Notable figures - At 21.3% efficiency, this panel is on par with typical \*\*PERC 550-600W\*\* modules - At 212.9 W/m² power density, roof space requirements are typical for \*\*PERC 550-600W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 550-600W\*\* median - At 31.8 kg, weight matches the \*\*PERC 550-600W\*\* median - 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 come with? The DeepBlue 3.0 Pro series includes a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This guarantees the module maintains a minimum power level for three decades, protecting your return on investment. As a Tier 1 manufacturer, JA Solar has the financial stability to back these long-term commitments. ### What does Half-Cut PERC cell technology mean in the DeepBlue 3.0 Pro, and why does it matter? Half-cut cells split each PERC cell in two, reducing internal current and resistive losses. In practice, the module performs better under partial shading - for example from a chimney or dormer - because the top half keeps generating power even when the bottom half is shaded. The Multi-Busbar architecture used in the DeepBlue 3.0 Pro further reduces the risk of micro-cracks, extending the panel's service life. ### Are JA Solar DeepBlue 3.0 Pro panels bifacial, and what does that mean for energy output? Yes, the DeepBlue 3.0 Pro series is available in a bifacial version (model designation JAM72D30 with dual-glass construction instead of a backsheet). Bifacial PERC cells capture light reflected from the ground surface, potentially increasing annual energy yield by several to over ten percent. The effect is most pronounced over bright surfaces such as concrete, gravel, or snow, and on ground-mounted systems. ### How does the 565 Wp DeepBlue 3.0 Pro perform in high summer temperatures? The temperature coefficient of Pmax for the DeepBlue 3.0 Pro is -0.35%/°C, which is better than older polycrystalline modules at -0.40%/°C or worse. On a hot day when cell temperature reaches 65°C, the module loses roughly 14% of its rated power - less than older technologies. This directly translates to a higher annual energy yield under real-world operating conditions. ### Can JA Solar DeepBlue 3.0 Pro panels be installed on a pitched roof? Yes. The DeepBlue 3.0 Pro measures 2333 × 1134 × 30 mm and weighs approximately 28 kg, which is standard for 72-cell-format modules and compatible with most professional aluminum rail and roof-hook mounting systems used on pitched roofs. The front snow load rating of 5400 Pa meets European structural standards, making it suitable for regions with heavy snowfall. ### How does the JA Solar DeepBlue 3.0 Pro differ from the base DeepBlue 3.0 series? The DeepBlue 3.0 Pro uses larger M10 silicon wafers (182 mm) instead of the smaller cells found in the base series, pushing module power up to 565 Wp with efficiency exceeding 21%. The upgraded Multi-Busbar design with additional busbars cuts resistive losses and improves cell durability. The result is a higher power-per-area ratio that directly lowers system BoS costs. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/20230712105042756-f95495c7de8b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, lighter, +3.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.2 pp | | [JA Solar JAM72D30-525/MB/1500V](https://comparepv.com/panel/ja-solar-jam72d30-525-mb-1500v) | 525 W | -25 W, -1.0 pp | | [JA Solar JAM72S30-530/MR](https://comparepv.com/panel/ja-solar-jam72s30-530-mr) | 530 W | Lighter, -0.8 pp, -5 yr warranty | | [JA Solar JAM72S30-535/MR](https://comparepv.com/panel/ja-solar-jam72s30-535-mr) | 535 W | Lighter, -0.6 pp, -5 yr warranty | | [JA Solar JAM72S30-540/MR](https://comparepv.com/panel/ja-solar-jam72s30-540-mr) | 540 W | Lighter, -0.4 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/shanghai-ja-solar-technology-co-ltd-jam72d30-550-gb-1500v Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
