Middle of its segment, needs the roof space
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.

N-type TOPCon cells virtually eliminate light-induced degradation (LID) and light and elevated temperature-induced degradation (LETID), which in conventional PERC technology causes 1–3% power loss during the first months of operation. This results in higher actual energy yield from day one of system commissioning.
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.
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.
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.
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.
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.
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.
- 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
