SMBB technology and the half-cut cell layout minimize partial-shading losses and suppress LID/LETID degradation. - **30-year linear performance warranty** - Jinko guarantees ≥87.4% of nominal power after 30 years with an annual degradation rate of 0.4% (post year 1), exceeding the common 25-year / 84.8% retention standard offered by P-type modules from Trina or JA Solar in the same vintage period. - **High unit power up to 635 Wp** - The 615–635 Wp power range reduces module count per installation and lowers BoS costs (cabling, racking, labor). The top-tier 635 Wp variant matches the peak wattage of comparable series including the Talesun TM7G78M and Longi Hi-MO X10 Explorer. - **Jinko Solar – BNEF bankable Tier 1** - Jinko Solar maintains continuous BNEF Tier 1 bankable status, facilitating non-recourse project financing and satisfying lender due diligence requirements for commercial and utility-scale installations. Founded in 2006, Jinko is among the global top four manufacturers each exceeding 80 GW annually. - **Robust mechanical load ratings** - Certified wind load of 2,400 Pa and snow load of 5,400 Pa ensure reliable operation in demanding climatic conditions and on rooftops with variable snow accumulation, meeting requirements common in Central European markets. ## Cons - **Series discontinued (2024)** - The Tiger Neo 78HL4-(V) line was discontinued in 2024 (released 2021). This limits availability of new modules, complicates replenishment in case of damage, and shortens the manufacturer's active technical support lifecycle compared to current Jinko product lines. - **Monofacial against bifacial peers** - All three identified peer comparables — Longi Hi-MO X10 Explorer, Sunpro TOPCon 210R Bifacial, and Talesun TM7G78M BIPRO — are bifacial modules offering a potential 10–20% additional yield from albedo reflection. The absence of bifaciality is a material limitation for ground-mount and light-membrane rooftop installations where bifacial factor directly impacts LCOE. - **Efficiency up to 22.72% trails segment leaders** - At the same module footprint, the Longi Hi-MO X10 Explorer and Sunpro TOPCon 210R reach 23.5–23.51% efficiency, exceeding the 78HL4-(V) maximum by approximately 0.78 percentage points. On a 100 kWp installation, this gap equates to roughly 3–4 m² less roof area needed — or proportionally higher yield at the same footprint. ## About this series Jinko Solar's Tiger Neo 78HL4-(V) series was designed for maximum yield from every square meter - these are monocrystalline N-type modules featuring TOPCon technology and a half-cell structure. This design handles partial shading more effectively and minimizes heating losses. This translates to more stable energy production in variable conditions, especially on rooftops with obstacles, installations near attics, and facilities where shade appears periodically. A key feature is **high resistance to degradation**, typical of N-type cells - translating to **better predictability of yield** over the long term and lower power drop risks compared to many standard P-type modules. Additionally, **a lower temperature coefficient** helps maintain performance during summer, and **a robust construction** (anti-reflective glass and housing with a high-sealability rating) facilitates trouble-free operation. This is an excellent choice for **commercial and industrial installations**, PV farms, and large rooftops, where yield, reliability, and minimizing losses in real operating conditions matter. ## Notable figures - At 22.2% efficiency, this panel is 0.6pp below the \*\*N-type 600-650W\*\* median of 22.8% - At 221.8 W/m², this panel generates 5.9 W/m² less per unit area than \*\*N-type 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*N-type 600-650W\*\* median - Weight of 29.5 kg (3.0 kg below \*\*N-type 600-650W\*\* median of 32.5 kg) allows easier transport and roof mounting - In the top 42% for efficiency among all N-type panels ## Questions ### Is the Jinko Solar Tiger Neo 78HL4-(V) series still available for purchase? The Tiger Neo 78HL4-(V) series has been discontinued and is no longer in active production. Some units may still be found with distributors clearing existing stock, but official manufacturing of this line has ended. For new installations, it is advisable to consider currently available successors within Jinko Solar's Tiger Neo or Neo N-type lineup. ### What is the rated power of the Jinko Solar Tiger Neo 78HL4-(V) and what type of installations is it designed for? The module's peak power output is 635 Wp under standard test conditions (STC). Its large footprint (approx. 2465 × 1134 mm) and high per-unit power make this series best suited for commercial and industrial installations, utility-scale PV farms, and large flat roofs where maximizing energy yield per installation hour is the primary goal. ### How does the TOPCon N-type cell technology in the Tiger Neo 78HL4-(V) compare to standard P-type PERC modules? N-type TOPCon cells deliver lower long-term degradation rates and a better temperature coefficient (approx. -0.29%/°C) compared to standard P-type PERC modules. This translates to smaller power losses on hot days and more predictable energy production over the panel's lifetime. TOPCon also eliminates LID (light-induced degradation), which is a known issue in P-type cells. ### What warranties does the Jinko Solar Tiger Neo 78HL4-(V) come with? The manufacturer provides a 12-year product warranty covering material and workmanship defects, and a 30-year linear power output warranty. The linear warranty structure caps annual degradation at approximately 0.4% after the first year, guaranteeing roughly 87.4% of nominal power output at year 30. ### Do the Tiger Neo 78HL4-(V) modules handle partial shading well? Yes. The half-cut cell layout splits each cell in two, reducing mismatch losses under partial shading and lowering internal resistive heating. In practice, this means more stable performance on rooftops with chimneys, HVAC units, or parapets where shadows fall across part of the array at specific times of day. ### What mechanical load ratings do the Jinko Solar Tiger Neo 78HL4-(V) modules carry — are they suitable for harsh climates? The modules are rated for snow loads up to 5400 Pa and wind loads up to 2400 Pa, meeting demanding structural requirements. Anti-reflective coated glass and a high IP-rated junction box ensure reliable long-term operation across a wide range of climates, including regions with heavy snowfall or strong winds. ## 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 | +30 W, cooler, +3.0 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +25 W, cooler, +2.8 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +50 W, cooler, +2.6 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +50 W, cooler, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +50 W, heavier, +2.6 pp | | [Jinko Solar JKM605N-78HL4-BDV](https://comparepv.com/panel/jinko-solar-jkm605n-78hl4-bdv) | 605 W | -15 W, heavier, -0.5 pp | | [Jinko Solar JKM610N-78HL4-BDV](https://comparepv.com/panel/jinko-solar-jkm610n-78hl4-bdv) | 610 W | Hotter, heavier, -0.4 pp | | [Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W)](https://comparepv.com/panel/jinkosolar-jkm615-635n-78hl4-v-f6-en-615w) | 615 W | Very close match | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +60 W, cooler, +3.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +55 W, cooler, +2.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +80 W, heavier, +2.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +75 W, heavier, +2.7 pp | --- Source: https://comparepv.com/panel/jinkosolar-jkm615-635n-78hl4-v-f6-en-620w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
