The ~2.5 percentage-point advantage translates to a smaller array footprint and lower BoS costs for the same energy yield. - **Low Tco and controlled degradation** - The power temperature coefficient is -0.26%/°C (vs. typical PERC modules at -0.34 to -0.38%/°C), yielding measurably higher output on hot days. Linear degradation of ≤0.40%/yr after year one (≤1% in year 1) guarantees ≥87.4% of nameplate power after 30 years — a critical LCOE parameter for utility-scale projects. - **30-year linear power warranty** - Jinko Solar backs the series with a 30-year linear power output warranty at ≤0.40%/yr degradation — top tier for utility-scale modules. Peer comparables from the context (Hiwatt, Techwise, ZNShine) do not publish equivalent warranty terms for this power class, giving Tiger Neo III a clear edge in project bankability assessments. - **~85% bifaciality ±5% (dual glass)** - The dual-glass bifacial construction at 85% bifaciality (±5%) enables 5–25% additional yield from ground-reflected irradiance (albedo ≥0.25). Heat-strengthened glass on both sides delivers superior resistance to salt mist, ammonia, and mechanical loads — critical for ground-mount farms, floating PV, and harsh-environment C&I installations. - **JinkoSolar – BNEF #1 Bankability (10 consecutive years)** - JinkoSolar is the only manufacturer to achieve 100% bankability in BloombergNEF's 2025 PV Module Bankability Survey and holds Tier-1 status in the BNEF Q2 2026 ranking with ~120 GW/yr production capacity. The manufacturer's financial standing minimizes warranty risk for projects financed with non-recourse debt. ## Cons - **Higher weight – dual glass vs. backsheet** - Dual-glass modules in the 650–670 W class typically weigh 32–35 kg, roughly 20–30% more than equivalent glass-backsheet modules (~26–28 kg). For rooftop installations this may require structural load verification and increases racking and BoS costs — a particularly relevant constraint for retrofits on existing buildings. - **Product warranty: 12 years** - The workmanship warranty covers 12 years — standard for the utility-scale segment, but below premium-tier offers (e.g., REC Alpha: 20 years, Panasonic/EverVolt: 25 years). For bank-financed C&I projects with a >15-year investment horizon, this may be a meaningful parameter during lender due diligence. ## About this series Jinko Solar’s Tiger Neo III 66QL6-BDV series are bifacial modules with a **dual glass** construction, designed to genuinely increase energy yield without complicating the installation project. The application of **N-type TOPCon cells** translates into excellent performance under challenging conditions - during low light, early morning and evening hours, and overcast skies, where many standard modules lose efficiency. Another distinguishing feature is **high bifaciality**: the rear side effectively uses reflected light, which is significant on light-colored grounds, membrane-covered roofs, gravel, or elevated structure installations. This series is tailored for investors who focus on LCOE and aim to “extract more” from the same surface area - from ground-mounted farms and floating projects to large commercial and industrial (C&I) rooftops. In practice, it helps reduce BOS costs, as the high power per module means fewer units, fewer connections, and faster installation. It stands out from the competition by combining **efficiency** with a focus on stable, long-term yield and structural durability. ## Notable figures - At 24.1% efficiency, this panel is 1.7pp above typical \*\*TOPCon 650-700W\*\* modules (median: 22.4%) - 240.6 W/m² power density - 16.9 W/m² more than \*\*TOPCon 650-700W\*\* median (223.7 W/m²), more power per roof area - -0.26%/°C temperature coefficient (median: -0.29%/°C) - retains ~1% more power at high temperatures - At 32.5 kg, this panel is 2.1 kg lighter than \*\*TOPCon 650-700W\*\* median (34.6 kg) - easier handling during installation - 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces ## Questions ### What warranty does the Jinko Solar Tiger Neo III 66QL6-BDV series come with? The manufacturer offers a 12-year product warranty and a 30-year linear power output warranty. Annual degradation after the first year is only 0.4%, meaning the module retains at least 87.4% of its rated power after 30 years. This is one of the strongest warranty packages available in the bifacial N-type module segment. ### What does 85% bifaciality mean for the Tiger Neo III 66QL6-BDV and how much extra energy does the rear side generate? An 85% bifaciality factor (±5%) means the rear side produces up to 85% of the power generated by the front. On high-albedo surfaces — concrete, gravel, white TPO membrane, or elevated racking — annual energy yield increases by 5–15%. For a 670W front-side module, the rear can contribute an additional 500–570 W of peak power. ### How does the TOPCon technology in the Tiger Neo III 66QL6-BDV compare to standard PERC cells? N-type TOPCon cells achieve up to 24.8% efficiency — significantly higher than typical P-type PERC cells at around 21–22%. They also have a lower temperature coefficient (-0.26%/°C), so the module loses less power on hot days. TOPCon cells are more resistant to light-induced degradation (LID) and potential-induced degradation (PID), delivering better energy yield throughout the full 30-year warranty period. ### How do the Tiger Neo III 66QL6-BDV modules perform in low-light conditions and on overcast days? The series generates up to 3.6% more power at 200 W/m² irradiance compared to standard-class modules — a key advantage in climates with frequent cloudy mornings and evenings. The low temperature coefficient (-0.26%/°C) also limits power losses during summer heat waves when conventional modules experience noticeable output drops. ### How heavy is the Jinko Tiger Neo III 66QL6-BDV panel and does it require special racking? The module weighs approximately 32.5 kg with dimensions of 2382×1134×30 mm. The dual glass construction is heavier than standard glass-backsheet panels but provides superior mechanical durability and a longer service life. When designing flat-roof, ground-mount, or floating PV structures, the additional dead load must be accounted for — consultation with a structural engineer is strongly recommended. ### Is the Tiger Neo III 66QL6-BDV series suitable for large-scale solar farms and commercial & industrial (C&I) applications? Yes, the series is engineered for utility-scale and C&I projects. The 670W power class and 1500V system compatibility reduce the number of modules and string connections needed, directly cutting BoS costs and speeding up installation. The IP68-rated junction box ensures reliability in challenging field conditions, while the dual glass design eliminates rear-surface degradation risks in floating PV and elevated-racking deployments. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/jkm650-670n-66ql6-bdv-d1-p8-cc-en-06fccf9247a4.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Lighter, +1.1 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +30 W, lighter, +1.1 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +25 W, lighter, +0.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Lighter, +0.9 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +50 W, heavier, +0.9 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +45 W, heavier, +0.8 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +20 W, lighter, +0.7 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 | -45 W, hotter, -1.7 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 | -40 W, hotter, -1.5 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 | -35 W, hotter, -1.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +20 W, lighter, +0.7 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +20 W, +0.7 pp | --- Source: https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-650w-class 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.
