Over a 30-year project lifetime, this translates to several additional percentage points of cumulative energy yield compared to legacy technology. - **Up to 23.25% efficiency – top-tier segment** - Top variants of the series reach 23.25% module efficiency, matching direct competitors BYD AURO N NLBK-39 (23.25%) and Einnova Solarline TOPCon (23.25%) and trailing Astronergy ASTRO N5 (23.3%) by only 0.05 pp. The series ranks in the top decile of the 625–650 Wp module segment. - **30-year linear power warranty, 87.4% retention** - Jinko guarantees at least 87.4% of rated power output after 30 years of operation (degradation ≤0.4%/year) and 99% after Year 1. Many competitors in this price segment offer only 20- or 25-year power warranties, representing meaningfully higher risk in long-horizon financial models (P50/P90). - **Bifacial dual glass + 5,400 Pa snow load rating** - The glass-glass bifacial design enables albedo-driven energy gain (Jinko claims up to +20% power gain depending on surface reflectivity), while certified mechanical load ratings of 5,400 Pa (snow) and 2,400 Pa (wind) allow deployment in demanding climate zones without additional racking reinforcement. - **BNEF #1 Bankability – sole 100% rating** - JinkoSolar earned the top spot in Bloomberg BNEF's 2025 PV Module Bankability Survey for the tenth consecutive year, the only manufacturer to receive a 100% bankability rating from participating financial institutions. For EPC contractors and utility-scale developers, this directly reduces project financing costs and simplifies due diligence. ## Cons - **Module weight ~34 kg – structural demands** - The glass-glass construction weighs approximately 34–34.6 kg depending on variant, roughly 4–6 kg heavier than comparable glass-backsheet modules in the same power class. For rooftop retrofits and commercial installations, this may require structural load assessment and additional BoS costs for racking reinforcement. - **2021 release – newer generation available** - The Tiger Neo 78HL4-BDV was launched in 2021; Jinko introduced Tiger Neo 3.0 in 2024–2025 with module efficiency up to 24.8%. For investors prioritizing the absolute lowest LCOE or the most advanced module in the manufacturer's lineup, the newer generation offers a meaningful ~1.5 pp efficiency advantage at a similar TOPCon architecture. ## About this series Jinko Solar's Tiger Neo 78HL4-BDV series is designed with the goal of achieving maximum yield from every square meter of installation and stable performance year after year. The use of **N-type cells in TOPCon technology** helps minimize common power losses found in older-generation modules and enhances performance in poorer lighting conditions. The key advantage of this series is the **bifacial design** combined with **dual glass** - the module can utilize reflected light from the ground, resulting in a real increase in energy production in PV farms, flat-roof installations, and systems with light membranes or ballast. Additionally, **high mechanical strength** and a robust module structure facilitate design in challenging wind and snowy regions. The Tiger Neo 78HL4-BDV is the choice for investors, EPC contractors, and companies seeking to reduce LCOE, limit degradation risks, and extract more energy from the same installation footprint. ## Notable figures - Efficiency of 23.2% is 0.9pp above the \*\*TOPCon 650-700W\*\* median (22.4%) - Power density of 232.5 W/m² packs 8.8 W/m² more into the same footprint vs \*\*TOPCon 650-700W\*\* median (223.7 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 650-700W\*\* panels - #1239 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty does the Jinko Solar Tiger Neo 78HL4-BDV come with? The Tiger Neo 78HL4-BDV series comes with a 12-year product warranty covering manufacturing defects and material faults, plus a 30-year linear power output warranty guaranteeing at least 87.4% of rated power at year 30. Jinko Solar holds Tier 1 manufacturer status, providing financial stability and reliable warranty enforcement throughout the entire coverage period. ### How does the TOPCon technology in the Tiger Neo 78HL4-BDV compare to older PERC panels? N-type TOPCon cells deliver lower LID (light-induced degradation) and higher module efficiency of approximately 22.5%, compared to a typical 20–21% for PERC. The power temperature coefficient of around -0.29%/°C means less output loss on hot days. The Tiger Neo 78HL4-BDV generates more energy from the same roof area, with the improvement being most visible during summer months. ### Does the bifacial design of the Tiger Neo 78HL4-BDV actually boost energy yield on flat roofs? Yes, the bifacial gain is most significant on flat roofs covered with a light-colored membrane or gravel. Reflected irradiance absorbed by the rear glass can increase yield by 5–15% depending on surface albedo. The dual-glass construction also protects the rear cell surface and extends module service life, especially important in installations exposed to moisture and temperature cycling. ### How heavy is the Jinko Solar Tiger Neo 78HL4-BDV and can a standard roof structure handle it? The module measures 2465 × 1134 × 30 mm and weighs approximately 34 kg. This is a standard load for industrial and flat roofs, but a structural assessment is always recommended before installation, especially on older buildings. The module is certified for snow loads of 5400 Pa and wind loads of 2400 Pa, meeting requirements for most central and northern European climate zones. ### Is the Tiger Neo 78HL4-BDV suitable for installations in regions with heavy snow and harsh winters? Yes. The certified snow load rating of 5400 Pa qualifies the panel for demanding winter conditions. The dual-glass construction provides greater mechanical strength than standard backsheet modules. The operating temperature range of -40°C to +85°C ensures the panel withstands severe frost without risk of laminate damage, making it a reliable choice for high-latitude installations. ### What is the maximum power output of the Tiger Neo 78HL4-BDV and what type of installations is it designed for? The top variant in the series reaches 650 Wp under STC conditions. The module is designed primarily for utility-scale PV plants, large commercial rooftops, and industrial installations where high energy yield per square meter and low LCOE matter most. High per-module wattage reduces the total number of modules required, cutting costs on racking, cabling, and labor. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/jkm625-650n-78hl4-bdv-f9-en-1-6891e4fbc122.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 | +30 W, lighter, +1.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +1.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +1.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +50 W, cooler, +1.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +45 W, cooler, +1.6 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +1.6 pp | | [Jinko Solar JKM605N-78HL4-BDV](https://comparepv.com/panel/jinko-solar-jkm605n-78hl4-bdv) | 605 W | -45 W, hotter, -1.6 pp | | [Jinko Solar JKM610N-78HL4-BDV](https://comparepv.com/panel/jinko-solar-jkm610n-78hl4-bdv) | 610 W | -40 W, hotter, -1.4 pp | | [Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W)](https://comparepv.com/panel/jinkosolar-jkm615-635n-78hl4-v-f6-en-615w) | 615 W | -35 W, lighter, -1.2 pp | | [Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (620W)](https://comparepv.com/panel/jinkosolar-jkm615-635n-78hl4-v-f6-en-620w) | 620 W | -30 W, lighter, -1.1 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | Cooler, lighter, +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 | +20 W, cooler, +1.6 pp | --- Source: https://comparepv.com/panel/jinko-solar-co-ltd-jkm625-650n-78hl4-bdv-650w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
