Solid all-round for its segment
Jinko Solar's Tiger Neo 78HL4-BDV (Dual-glass Bifacial) is designed for maximum energy yield where every square meter counts and for stable performance over years. The use of dual-glass construction reduces the module's sensitivity to environmental conditions, improves resistance to micro-cracking, and enhances predictability in the long term. The key advantage is bifacial technology - the panel utilizes reflected light from the ground, significantly boosting energy production in ground-mounted installations, flat roofs, and on light surfaces.
This series relies on N-type cells, valued for their slower degradation and good performance at higher temperatures - ideal for Polish summer conditions and industrial projects. The modules are also designed for demanding environments thanks to their high mechanical durability and refined connection structure.
The Tiger Neo 78HL4-BDV is an excellent choice for utility-scale PV farms, large commercial rooftops, and investors seeking durability and additional yield from the rear side of the module.

Signals from the data
Commercial, utility-scale and hot-climate.
TOPCon technology virtually eliminates light-induced degradation (LID), with a temperature coefficient of Pmax at -0.29 %/°C – more favorable than typical PERC cells (-0.35 %/°C). Under Central European summer conditions (30–35 °C), this translates to roughly 1.5–2% higher daily energy yield compared to older cell technologies.
Peak efficiency of 23.25% places the series on par with leading peer comparables: BYD AURO N NLBK-39 (23.25%) and Einnova TOPCon 630–650 W (23.25%). Only Astronergy ASTRO N5 edges ahead at 23.3% — a 0.05 pp gap that is negligible in real-world project design.
Jinko Solar guarantees at least 87.4% of rated power after 30 years, with annual degradation capped at 0.4% after year one. This is 5 years longer than the 25-year warranty standard offered by many competitors and directly reduces the calculated LCOE for utility-scale projects with long financing horizons.
Replacing the rear backsheet with a second 2 mm glass pane eliminates moisture ingress, reduces thermally induced microcracking, and effectively suppresses PID. The datasheet confirms a snow load rating of 5400 Pa — relevant for Central European climate conditions.
Jinko Solar achieved 100% bankability in the BloombergNEF PV Module Bankability Survey for 2024, making it the only manufacturer to hold that distinction for 10 straight years. In Q2 2026, it holds the top position in the BNEF Tier 1 ranking (120 GW/year production capacity), minimizing counterparty risk in externally financed projects.
The dual glass build raises module weight to 34.6 kg — approximately 15–20% heavier than comparable monofacial glass-backsheet modules of similar wattage (~29–31 kg). For rooftop installations on older buildings, this may require a structural engineering assessment or additional reinforcement, generating extra BoS costs.
- Efficiency of 22.5% matches the TOPCon 600-650W median
- At 225.4 W/m² power density, roof space requirements are typical for TOPCon 600-650W panels
- Temperature coefficient of -0.29%/°C matches the TOPCon 600-650W median
- At 34.0 kg, this panel is 1.3 kg heavier than the TOPCon 600-650W median (32.7 kg) - more demanding for installation crews
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
