Ranked 511th in the whole database. - **23.36% module efficiency** - Top 11% of the TOPCon 500-550 W segment, against a median of 22.73%. - **233.6 watts per square metre** - Top 11% of the TOPCon 500-550 W segment, against a median of 227.4. - **Best for:** Residential, commercial and hot-climate. ## Specification ### Electrical - **Rated power (Pmax):** 505 W - **Efficiency:** 23.36 % - **Voltage at Pmax (Vmp):** 33.12 V - **Current at Pmax (Imp):** 15.25 A - **Open-circuit voltage (Voc):** 38.85 V - **Short-circuit current (Isc):** 15.86 A - **Max system voltage:** 1500 V ### Temperature - **Temperature coefficient of Pmax:** -0.260 %/degC - **Temperature coefficient of Voc:** -0.240 %/degC - **Temperature coefficient of Isc:** 0.046 %/degC ### Cell and construction - **Cell type:** Monocrystalline - **Cell technology:** TOPCon - **Cell count:** 204 - **Bifacial:** yes ### Physical - **Length:** 1906 mm - **Width:** 1134 mm - **Thickness:** 30 mm - **Weight:** 26.3 kg - **Area:** 2.16 m2 - **Power density:** 233.6 Wp/m2 ### Warranty and degradation - **Product warranty:** 15 years - **Performance warranty:** 30 years - **Output guaranteed at end of warranty:** 88.8 % - **First-year degradation:** 1.00 % - **Annual degradation:** 0.35 % - **Output after 30 years:** 449 W ## Rank in the whole catalogue | Measure | Position | | --- | --- | | Efficiency | 937 of 14005 | | Power density | 926 of 14005 | | Temperature coefficient | 511 of 14005 | | Weight | 5512 of 14005 | | Warranty | 21 of 14005 | ## Pros - **Efficiency leader among peers** - Peak efficiency of 24.06% outperforms direct comparables: HT-SAAE HT54-18X(N) at 23.8%, TCL Zhonghuan HSM-BD60-LA at 23.5%, and DAH Solar DHN-60R20/DG at 23.0%. For space-constrained installations, this translates into higher energy yield without increasing the module count. - **Temperature coefficient of -0.26%/°C** - The Pmax temperature coefficient of -0.26%/°C is approximately 35–40% better than typical PERC modules (-0.40 to -0.45%/°C) and 10–13% better than standard TOPCon (-0.29 to -0.30%/°C). At summer module temperatures of 55–60°C, this delivers roughly 4.5% higher output than a PERC module with the same STC nameplate rating. - **Low N-type degradation, no LID** - N-type TOPCon cell technology eliminates LID and minimizes LeTID. The manufacturer guarantees degradation of ≤1% in Year 1, then ≤0.4%/year linear, retaining ≥87.4% of rated power after 30 years — compared to ≤0.45%/year and ≥84.8% at 25 years for standard P-type PERC modules. - **30-year linear power warranty** - A 30-year linear performance warranty with a ≥87.4% floor exceeds the 25-year standard offered by the peer comparables. For a commercial 500 kWp project, the extended warranty horizon lowers LCOE and simplifies long-term project finance structuring. - **BNEF #1 bankability + bifacial glass-glass** - JinkoSolar is the only PV module manufacturer recognized as bankable by 100% of respondents in the Bloomberg NEF bankability survey for 10 consecutive years (2025 report), significantly easing project financing. A bifacial factor up to 85% adds 5–25% rear-side energy gain, and the dual-glass (2+2 mm) structure enhances resistance to PID, moisture ingress, and microcracks. ## Cons - **26.3 kg heavier than glass-backsheet** - The dual-glass construction results in a module weight of 26.3 kg, compared to 21–23 kg for typical glass-backsheet TOPCon panels of similar wattage. On rooftop installations of older buildings, this may require a structural load assessment, adding to project engineering costs. ## About this series Jinko Solar's Tiger Neo III 51QL6-BDV series are modules designed for maximum yield from the same surface area - especially where every square meter of roof or row in a solar farm counts. What sets them apart is the **N-type TOPCon cell technology**, engineered for more stable long-term operation and superior energy conversion in conditions where conventional modules lose their edge. In practice, this means higher yields not just under full sun but also during challenging daylight hours. A key feature is **bifaciality** - the panels can harvest energy from both sides, effectively boosting energy production on ground-mounted systems, light-colored roofs, and any surface that reflects sunlight well. The **glass-glass (double glass) construction** enhances resistance to environmental factors and ensures durability in demanding locations. Furthermore, their **low high-temperature sensitivity** means they sag less during hot summer months. This is an excellent choice for homes with limited space, companies seeking a lower LCOE, and commercial projects where predictable energy yields and long-term reliability are crucial. ## Notable figures - At 23.4% efficiency, this panel is 0.6pp above typical \*\*TOPCon 500-550W\*\* modules (median: 22.7%) - At 233.6 W/m² power density, this panel generates 6.2 W/m² more per unit area than \*\*TOPCon 500-550W\*\* median (227.4 W/m²) - Temperature coefficient of -0.26%/°C vs median -0.29%/°C means ~1% less power loss at 65°C - Bifacial design (85% factor) captures reflected light - adds 4-13% yield on ground-mount or white roof - #937 for efficiency, #511 for temperature performance out of 14005 panels ## Questions ### What warranty does the Jinko Solar Tiger Neo III 51QL6-BDV series come with? The Tiger Neo III 51QL6-BDV series carries a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. The power warranty guarantees that the module will maintain a precisely defined minimum output level over three decades. The 30-year performance warranty is especially relevant when calculating LCOE for commercial projects and utility-scale PV plants. ### Does the bifacial design of the Tiger Neo III 51QL6-BDV actually increase energy yield? Yes, though the gain depends heavily on installation conditions. Bifacial modules harvest light from both the front and rear sides, which on ground-mounted systems with gravel or grass surfaces can add several percent to annual energy yield. The largest gains come from highly reflective ground surfaces and sufficient module clearance height. On a shaded or dark roof, the bifacial contribution will be minimal. ### How does TOPCon technology in the Tiger Neo III 51QL6-BDV differ from standard PERC cells? TOPCon (Tunnel Oxide Passivated Contact) uses an N-type silicon base with lower annual degradation rates and better low-light and diffuse-light conversion compared to P-type PERC. In practice, this means higher energy output in the morning, evening, and on overcast days. The result is a better overall performance ratio (PR) for the system, which is particularly valuable in climates with significant cloud cover. ### Are the Jinko Solar Tiger Neo III 51QL6-BDV panels suitable for a residential rooftop installation? Yes. With a maximum output of 520 Wp per module, fewer panels are needed to cover a typical household's energy demand, which is a clear advantage on roofs with limited usable area. However, larger 500+ Wp modules require a structural assessment of the roof's load-bearing capacity and a compatible inverter with appropriate MPPT voltage input ranges. ### How does the glass-glass construction of the Tiger Neo III 51QL6-BDV affect module durability? Dual-glass construction replaces the traditional polymer backsheet with a second glass layer, significantly improving resistance to moisture ingress, UV degradation, and cell micro-cracking. Glass-glass modules show lower susceptibility to potential-induced degradation (PID) and better withstand harsh environmental conditions. This directly supports the 30-year power warranty, as enclosure durability is fundamental to long-term field performance. ### Do the Tiger Neo III 51QL6-BDV panels suffer significant power loss in summer heat? N-type TOPCon technology delivers a more favorable temperature coefficient than standard PERC modules. This means each degree Celsius of cell temperature rise above STC results in a proportionally smaller power loss. In summer, when modules on rooftops reach 60-70°C, this advantage over older technologies becomes measurable and contributes to meaningfully higher annual energy yield from the system. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/jkm490-520n-51ql6-bdv-f2-eu-315c34f05647.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +1.6 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | -10 W, lighter, +1.4 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +1.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +50 W, lighter, +1.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | -15 W, lighter, +1.1 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +1.1 pp | | [Jinko Solar JKM440M-60HL4](https://comparepv.com/panel/jinko-solar-jkm440m-60hl4) | 440 W | -65 W, hotter, -3.0 pp | | [Jinko Solar JKM445M-60HL4](https://comparepv.com/panel/jinko-solar-jkm445m-60hl4) | 445 W | -60 W, hotter, -2.7 pp | | [Jinko Solar JKM450M-60HL4-V](https://comparepv.com/panel/jinko-solar-jkm450m-60hl4-v) | 450 W | -55 W, hotter, -2.5 pp | | [Jinko Solar JS182MHC120-450](https://comparepv.com/panel/jinko-solar-js182mhc120-450) | 450 W | -55 W, hotter, -2.6 pp | | [Jinko Solar JKM455M-60HL4](https://comparepv.com/panel/jinko-solar-jkm455m-60hl4) | 455 W | -50 W, hotter, -2.3 pp | | [Jinko Solar JS182MHC120-455](https://comparepv.com/panel/jinko-solar-js182mhc120-455) | 455 W | -50 W, hotter, -2.3 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +55 W, lighter, +1.4 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +45 W, lighter, +1.0 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +35 W, lighter, +1.0 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +35 W, lighter, +1.0 pp | --- Source: https://comparepv.com/panel/jinko-solar-jkm495-520n-51ql6-bdv-f2-eu-505w 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.
