This results in higher actual energy yield from day one of system commissioning. - **Temperature coefficient -0.29%/°C** - The power temperature coefficient of -0.29%/°C is meaningfully better than the -0.34% to -0.35%/°C typical of PERC modules. The ~0.05–0.06 pp/°C advantage translates to approximately 1–2% higher output at a typical cell operating temperature of 60°C — a significant gain for summer peak-production periods. - **30-year linear warranty, ≥87.4% power retention** - JinkoSolar guarantees ≥87.4% power retention after 30 years, with annual degradation capped at 0.4%. The market standard remains 25–27 years at 84.8%–86% retention. The extended warranty horizon improves project bankability and simplifies financial models for utility-scale PV assets under non-recourse debt financing. - **Bifacial dual glass with ~80% bifaciality** - The bifacial dual-glass construction with ~80% (±5%) bifaciality factor captures reflected irradiance from the ground surface. On a typical white-gravel utility-scale site (albedo ~0.25), this delivers a real annual energy gain of 5–10% over a monofacial equivalent. The 2+2 mm dual-glass build also provides superior resistance to moisture ingress, thermal cycling, and corrosive environments. - **Jinko Solar – BNEF Tier-1, 100% bankability** - JinkoSolar is the only manufacturer to receive 100% bankability recognition in Bloomberg NEF's PV Module Bankability Survey for 10 consecutive years (2024/2025). Its BNEF Tier-1 status and 120 GWp annual production capacity materially reduce counterparty risk in non-recourse financed projects and support favorable insurance underwriting terms. ## Cons - **Module efficiency trails peer comparables** - The series achieves 21.64–22.18% efficiency, while direct peer comparables — HT-SAAE HT66-18X(ND)-F and Weran Solar LR7-72HTH — claim 23.0%, and MY Solar G&A N-Type TOPCon reaches 22.95% at the same 620 Wp peak power. The 0.77–1.36 pp efficiency gap requires approximately 3–6% more module area to achieve the same installed capacity, increasing BoS and land costs for space-constrained projects. - **Weight ~34.6 kg increases BoS costs** - The dual-glass construction raises module weight to approximately 34.6 kg, compared to ~26–28 kg for a typical framed monofacial panel. This requires heavier racking structures, increasing mounting system costs by roughly 8–15% and extending installation time — a relevant factor for large ground-mount projects priced per MW. ## About this series The Jinko Solar Tiger Neo N-type 78HL4-BDV series is an advanced solution for demanding investments, based on innovative **TOPCon** technology. The use of N-type cells significantly reduces light-induced and temperature-induced degradation, which translates into stable and predictable performance over long decades of use. These models are characterized by a **bifacial dual glass** design, allowing for the generation of a significant amount of additional energy from radiation reflected from the ground, which is crucial for large ground-mounted farms and industrial installations. Thanks to the use of **SMBB** (Super Multi Busbar) technology, these panels effectively minimize internal resistance and optimize current flow, which tangibly increases yields even in difficult lighting conditions or heavy cloud cover. This product is primarily dedicated to the commercial and utility-scale sector, where the priority is to maximize return on investment while reducing system costs. What distinguishes them from competing solutions is an exceptionally high **bifaciality** factor and an excellent power temperature coefficient, guaranteeing high efficiency on hot days. Choosing this series is a strategic investment in the **highest power density** and extreme structural durability, which effectively addresses the issue of long-term efficiency decline in harsh environmental conditions. ## Notable figures - Module efficiency of 21.8% is 0.9pp below average for \*\*N-type 600-650W\*\* panels (median: 22.8%) - Power density of 218.2 W/m² is 9.5 W/m² below \*\*N-type 600-650W\*\* median (227.7 W/m²) - needs more roof space - At -0.30%/°C, hot weather performance is typical for \*\*N-type 600-650W\*\* panels - At 34.6 kg, this panel is 2.1 kg heavier than the \*\*N-type 600-650W\*\* median (32.5 kg) - more demanding for installation crews - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### What warranty does the Jinko Solar Tiger Neo N-type 78HL4-BDV come with? The Tiger Neo 78HL4-BDV series carries a 12-year product warranty covering defects in materials and workmanship, plus a 30-year linear power output warranty. Jinko Solar guarantees the modules will retain at least 87.4% of their rated power after 30 years of operation. This is among the most competitive long-term warranties available for industrial-grade PV modules and reflects the durability of the dual glass construction. ### How heavy is the Jinko Tiger Neo 78HL4-BDV and is it suitable for an industrial rooftop installation? The bifacial dual glass module weighs approximately 34.6 kg and measures 2465 × 1134 × 30 mm. Due to its weight and large form factor, the 78HL4-BDV series is primarily designed for commercial and utility-scale ground-mounted installations. Before mounting on an industrial rooftop, a structural load assessment by a certified engineer is required, as the module weight significantly exceeds that of typical residential panels. ### What does bifacial dual glass technology mean in the Tiger Neo 78HL4-BDV and how much extra energy can it generate? Bifacial dual glass means the N-type TOPCon cells are encapsulated between two glass layers instead of a polymer backsheet, allowing both sides to generate electricity. The rear side captures albedo light reflected from the ground, typically yielding 5–20% additional energy compared to monofacial modules. The gain is highest on reflective surfaces such as concrete, gravel, or snow, and with elevated mounting heights typical of utility-scale ground-mounted solar farms. ### Do Jinko Tiger Neo N-type 78HL4-BDV panels lose significant power output on hot days? No – the N-type TOPCon cells in the 78HL4-BDV series have a superior temperature coefficient for Pmax compared to standard P-type PERC modules, meaning they lose less power as operating temperature rises and deliver higher real-world energy yields on hot days. The module's rated operating temperature range is -40°C to +85°C, ensuring reliable year-round performance. ### What is SMBB technology in the Jinko Tiger Neo 78HL4-BDV and what are its practical benefits? SMBB (Super Multi Busbar) replaces the traditional 5–6 busbars with a greater number of thinner ones across each cell. This shortens the current path, reduces series resistance, and improves light harvesting. In practice, it results in higher yields under diffuse light conditions and lower energy losses under partial shading — a key advantage for large commercial installations exposed to variable weather conditions. ### Is the Jinko Solar Tiger Neo 78HL4-BDV suitable for building a large utility-scale solar farm? Yes, the 78HL4-BDV series was engineered for commercial and utility-scale ground-mounted applications. High unit power up to 620 Wp, a high bifaciality factor, and certified resistance to snow loads (5,400 Pa) and wind loads (2,400 Pa) make it an optimal choice for developers focused on low LCOE and maximum power density per square meter across large PV projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JKM605-625N-78HL4-BDV-F3-EN-2257af2f6e69.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +40 W, lighter, +3.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -50 W, lighter, +3.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +3.0 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +2.8 pp | | [Longi Solar LR8-66HVD-660M](https://comparepv.com/panel/longi-lr8-66hvd-660m) | 660 W | +50 W, cooler, +2.6 pp | | [Jinko Solar JKM605N-78HL4-BDV](https://comparepv.com/panel/jinko-solar-jkm605n-78hl4-bdv) | 605 W | Very close match | | [Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W)](https://comparepv.com/panel/jinkosolar-jkm615-635n-78hl4-v-f6-en-615w) | 615 W | Cooler, lighter | | [Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (620W)](https://comparepv.com/panel/jinkosolar-jkm615-635n-78hl4-v-f6-en-620w) | 620 W | Cooler, lighter, +0.4 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +70 W, lighter, +3.4 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +65 W, lighter, +3.2 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +90 W, cooler, +3.2 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +85 W, cooler, +3.1 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +60 W, lighter, +3.0 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +60 W, lighter, +3.0 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +60 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/jinko-solar-jkm610n-78hl4-bdv Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
