The Super Multi Busbar (SMBB) architecture shortens electron travel distance to the busbar, suppresses LID/LETID, and improves low-light current collection. - **BNEF #1 Bankability – 10 consecutive years** - JinkoSolar is the only module manufacturer to achieve a 100% bankability rating in the Bloomberg BNEF PV Module Bankability Survey 2024, maintaining Tier-1 status for over a decade. For project financiers and investors, this translates to reliable warranty enforcement throughout the 30-year asset lifetime. - **30-year linear power warranty** - Jinko guarantees a linear power degradation schedule over 30 years, exceeding the 25-year standard offered by peers such as JA Solar and Trina Solar. A linear warranty structure reduces financial risk in DCF models and supports stronger project IRR. - **Certified mechanical strength** - The series is certified for 5400 Pa snow load and 2400 Pa wind load, making it well-suited for utility-scale PV farms and large commercial rooftop installations in regions with heavy snowfall or high wind exposure. ## Cons - **Series discontinued (since ~2023)** - The 78HL4-(V) series ended production around 2023. This limits availability of new units on the secondary market, raises the risk of sourcing identical modules for warranty replacements or capacity additions, and may cause electrical mismatch issues when expanding existing string arrays. - **Mono-facial vs. bifacial peer set** - Direct competitors at the 635 Wp power class — LONGi Hi-MO X10 Explorer (23.50%) and Sunpro TOPCon 210R (23.51%) — are bifacial modules with approximately 0.78 pp higher front-side efficiency. In a typical ground-mounted installation, bifacial modules harvest an additional 10–15% energy from the rear side, yielding a materially lower LCOE and higher annual energy output compared to this mono-facial design. ## About this series Jinko Solar's Tiger Neo 78HL4-(V) series are N-type monocrystalline modules engineered for maximum energy yield in installations operating under conditions far from ideal. The use of N-type cells minimizes light-induced degradation, translating to more stable long-term performance, which appeals to investors focused on realistic returns rather than just catalog power ratings. In practice, these panels are distinguished by their **high efficiency under low-light conditions** and **lower susceptibility to performance losses over time**, making them ideal for locations with frequent cloud cover or less favorable roof orientations. Additionally, the application of **SMBB technology** enhances current collection and reduces losses during partial shading, while **PID resistance** is crucial for installations operating under demanding electrical and environmental conditions. Thanks to its robust construction and resistance to demanding external factors, this series is well-suited for **large commercial installations and utility-scale PV farms**, where reliability, consistent parameter performance, and predictable energy output over years are paramount. ## Notable figures - Efficiency of 22.7% matches the \*\*N-type 600-650W\*\* median - Power density of 227.2 W/m² matches the \*\*N-type 600-650W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*N-type 600-650W\*\* median - 29.5 kg weight - 3.0 kg lighter than \*\*N-type 600-650W\*\* median (32.5 kg), reducing installation effort - Ranked #3245 out of 14005 panels for efficiency in the database ## Questions ### Is the Jinko Solar Tiger Neo 78HL4-(V) series still available for purchase? The Tiger Neo 78HL4-(V) series has been discontinued by Jinko Solar and is no longer actively offered as a new product. If you require similar N-type specifications, we recommend checking with distributors for remaining stock or exploring newer Jinko Solar series that continue this product line. ### What warranty does the Jinko Solar Tiger Neo 78HL4-(V) carry? Jinko Solar offers a 12-year product warranty and a 30-year linear power output warranty on the Tiger Neo 78HL4-(V) modules. Thanks to the N-type cell technology and its inherently lower LID degradation, the declared residual power after 30 years is realistically attainable — one of the stronger warranty standards available in the utility-scale PV module segment. ### How does the N-type cell technology in the 78HL4-(V) compare to standard PERC modules? The N-type cells used in the Tiger Neo 78HL4-(V) exhibit significantly lower Light-Induced Degradation (LID) compared to PERC cells, meaning minimal power loss in the first weeks of operation and more consistent output over the full warranty period. N-type technology also responds better to diffuse irradiance, delivering a higher energy yield under overcast conditions common in Central European climates. ### Are the Tiger Neo 78HL4-(V) panels rated up to 635 Wp suitable for large commercial installations and solar farms? Yes, the 78HL4-(V) series with up to 635 Wp peak power is designed primarily for commercial rooftop systems and utility-scale PV farms. The high per-module power output reduces the total module count, lowering Balance of System (BoS) costs. The reinforced frame handles wind loads up to 2,400 Pa and snow loads up to 5,400 Pa, making it well-suited for demanding outdoor deployments. ### How do the Jinko Solar Tiger Neo 78HL4-(V) panels perform in low-light or overcast conditions? The Tiger Neo 78HL4-(V) modules are optimized specifically for real-world conditions that fall short of STC. The SMBB technology improves current collection and reduces the impact of partial shading, while a low power temperature coefficient of -0.30%/°C means less power loss on cooler, overcast days compared to older PERC modules — a meaningful advantage in northern European climates. ### What is SMBB technology and why does it matter in the Tiger Neo 78HL4-(V) series? SMBB (Super Multi Busbar) replaces a few wide busbars with many thin ribbons across each cell, improving current distribution, reducing resistive losses, and increasing resistance to micro-cracks. In practice this translates to a higher energy yield and reduced risk of module degradation from mechanical stress during shipping and long-term field operation — contributing to more predictable performance over the 30-year power warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/207290642265d1b4da9e838-621184533ffe.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +45 W, cooler, +2.5 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +40 W, cooler, +2.3 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.3 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +35 W, cooler, +2.1 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +35 W, cooler, +2.1 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.1 pp | | [Jinko Solar JKM605N-78HL4-BDV](https://comparepv.com/panel/jinko-solar-jkm605n-78hl4-bdv) | 605 W | -30 W, heavier, -1.1 pp | | [Jinko Solar JKM610N-78HL4-BDV](https://comparepv.com/panel/jinko-solar-jkm610n-78hl4-bdv) | 610 W | -25 W, heavier, -0.9 pp | | [Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W)](https://comparepv.com/panel/jinkosolar-jkm615-635n-78hl4-v-f6-en-615w) | 615 W | -20 W, -0.7 pp | | [Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (620W)](https://comparepv.com/panel/jinkosolar-jkm615-635n-78hl4-v-f6-en-620w) | 620 W | -15 W, -0.5 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +65 W, heavier, +2.3 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +60 W, heavier, +2.2 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +35 W, heavier, +2.1 pp | --- Source: https://comparepv.com/panel/jinkosolar-jkm615-635n-78hl4-v-f6-en-635w-variant Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
