N-type architecture virtually eliminates LID degradation, resulting in more predictable energy yields throughout the 30-year service life. - **Up to 23.32% efficiency - top of peer group** - Peak module efficiency of 23.32% matches Canadian Solar TOPBiHiKu6 Anti-Dust (23.3%) and exceeds both Leapton LP182\*199-M-72-NH and AUSTA ENERGY AU-156MH (each at 22.54%) by nearly 0.8 percentage points. At identical roof or ground area, this translates to measurably higher annual energy yield without increasing module count. - **Bifacial dual-glass - up to 30% rear-side gain** - The dual-glass bifacial design achieves up to 30% bifacial gain (per official JinkoSolar Tiger Neo whitepaper), effectively harvesting albedo from high-reflectivity surfaces such as TPO/PVC membranes, gravel, and snow. Double-glass construction eliminates EVA yellowing risk and significantly reduces long-term PID susceptibility vs. glass-backsheet alternatives. - **30-year linear power warranty (≥87.4%)** - JinkoSolar guarantees ≥99% rated output in year 1 and ≥87.4% after 30 years, with annual degradation of approximately 0.4%. Combined with a 12-year product warranty and 0~+3 W positive power tolerance, this series carries one of the strongest warranty packages available in the >600 Wp segment. - **Jinko Solar - BNEF #1 bankability for 10 consecutive years** - JinkoSolar is the only PV module manufacturer rated 100% bankable in the Bloomberg NEF PV Module Bankability Survey (2024), maintaining Tier-1 status for more than 10 consecutive years. This simplifies non-recourse project financing and reduces counterparty risk for institutional investors and project finance lenders. ## Cons - **Series discontinued in 2025** - The 66HL4M-BDV (605-630 W) series was discontinued in 2025 (released 2023, end\_year 2025). This results in limited and declining new-module availability on the market, creates supply-chain gaps for system expansions, and may complicate long-term serviceability and like-for-like replacement of failed units. ## About this series The Jinko Solar Tiger Neo 66HL4M-BDV (605-630W) series was designed for installations where achieving high yield from the same surface area and stable performance over a long lifespan are key priorities. These are **dual-sided (bifacial)** modules in a **dual-glass** construction, effectively utilizing reflected light from the ground - a real benefit on light-colored roofs, gravel, TPO/PVC membranes, or in farms with appropriate albedo. The used **N-type TOPCon cells** stand out with low susceptibility to typical degradation in the initial years of operation and good performance under lower irradiance. In practice, this means more predictable results, even under Poland's weather conditions. The modules feature a **positive power tolerance**, facilitating precise string design without the risk of "weaker panels". This is an excellent choice for **PV farms, industrial halls, and commercial buildings**, where longevity, environmental resistance, and maximizing energy output from each structural section are crucial. ## Notable figures - At 23.3% efficiency, this panel is 0.5pp above typical \*\*TOPCon 600-650W\*\* modules (median: 22.8%) - Power density of 233.2 W/m² packs 5.5 W/m² more into the same footprint vs \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 600-650W\*\* median - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - #1012 for efficiency, #2220 for temperature performance out of 14129 panels ## Questions ### Is the Jinko Solar Tiger Neo 66HL4M-BDV (605-630W) series still available? The Tiger Neo 66HL4M-BDV series has been officially discontinued and is no longer in production. Modules may still be available in limited quantities from distributor stock. For new installations, it is worth asking about the current Jinko Solar series that have replaced this line. ### What warranty does the Jinko Solar Tiger Neo 66HL4M-BDV come with? Jinko Solar provides a 12-year product warranty covering manufacturing defects and a 30-year linear power warranty guaranteeing at least 87.4% of rated output after 30 years. The dual-glass construction also reduces moisture ingress, resulting in lower long-term degradation compared to conventional backsheet modules. ### Do the bifacial 66HL4M-BDV modules make practical sense in Polish or Central European conditions? Yes, though bifacial gain depends on ground albedo. In Poland, these modules perform best on light-colored rooftops with gravel ballast or white TPO/PVC membranes, and on ground-mount arrays with adequate clearance height. Realistic bifacial gain in this climate typically ranges from 5-15% over a comparable monofacial module at the same rated power. Dark surfaces reduce this benefit significantly. ### How does the Tiger Neo 66HL4M-BDV handle summer heat and low winter irradiance? The N-type TOPCon cells have a temperature coefficient of Pmax at -0.29%/°C, more favorable than typical PERC cells at -0.35%/°C, meaning smaller power losses on hot days. In low-irradiance conditions typical of Polish winters and overcast days, TOPCon also outperforms older technologies, delivering more predictable energy output year-round. ### What types of installations are the Tiger Neo 66HL4M-BDV 630W modules best suited for? At up to 630 Wp and 2382×1134 mm, these modules are designed primarily for utility-scale PV farms and large commercial installations such as warehouses, production halls, and industrial facilities. The 32.4 kg weight and large format require robust racking structures and an experienced installation crew. They are not recommended for typical residential rooftop systems due to their size and weight. ### How do the TOPCon cells in the 66HL4M-BDV differ from older PERC cells? TOPCon (Tunnel Oxide Passivated Contact) is an N-type technology that passivates surface defects using a thin tunnel oxide layer. This yields module efficiency up to 23.32%, lower first-year degradation, and resistance to LID (Light-Induced Degradation) that affects P-type PERC cells. The result is more stable and predictable energy production throughout the full 30-year warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/139922253066b9b360f0df1-9a1672a03d35.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +1.9 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +50 W, lighter, +1.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +45 W, lighter, +1.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +1.7 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +40 W, lighter, +1.5 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +40 W, lighter, +1.5 pp | | [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (605W column)](https://comparepv.com/panel/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-605w-column) | 605 W | -25 W, -0.9 pp | | [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (610W column)](https://comparepv.com/panel/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-610w-column) | 610 W | -20 W, -0.7 pp | | [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (615W column)](https://comparepv.com/panel/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-615w-column) | 615 W | -15 W, -0.6 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +70 W, cooler, +1.7 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +65 W, cooler, +1.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +40 W, cooler, +1.5 pp | --- Source: https://comparepv.com/panel/jinko-solar-co-ltd-jkm605-630n-66hl4m-bdv-f3-en-630w 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.
