The Tiger Neo III series represents the third generation of Jinko Solar's flagship modules, built on the latest N-type TOPCon technology, which limits cell degradation and maintains stable power output throughout the entire lifespan of the installation. The panels use a half-cut cell structure combined with advanced multi-busbar interconnections, reducing resistive losses and improving mechanical resistance to micro-cracks. Thanks to its bifacial design, the module also captures solar radiation from the rear side, generating additional energy from reflected and diffuse light - a solution especially valued by investors installing systems on light-colored surfaces, flat roofs, or ground-mounted solar farms. The series also stands out with a low temperature coefficient, translating into better performance on hot days and more stable output under low-irradiance conditions. Tiger Neo III answers the market's growing demand for high power density panels that reduce the surface area needed to reach a given system capacity, lowering overall BoS costs. It is a solid choice for both residential and commercial investors seeking proven, bankable technology backed by a long-term warranty and a low LCOE.

What owners get
Latest-gen N-type TOPCon cells

Third-generation TOPCon cells with ~27% cell-level efficiency deliver 24.8% module efficiency and a declared degradation profile of 1% in year one followed by 0.4%/year linear thereafter - a meaningful improvement over legacy PERC modules.

High power density up to 670 Wp

Unit power up to 670 Wp with efficiency up to 24.8% reduces the module count and roof/ground area needed to hit a target array size, directly lowering BoS costs (racking, wiring, installation labor).

Bifacial design with 85±5% bifaciality

The bifacial variant of the series reaches an 85±5% bifaciality factor, adding 553-570 W of rear-side output under optimal conditions - notably higher than the 70-75% typical of competing BC-technology panels.

30-year linear power warranty

Power warranty extends to 30 years with a low 0.4% annual degradation rate, one of the longer coverage periods on the market and a supportive factor for low LCOE in project financial models.

Tier-1, bankable manufacturer

Jinko Solar has operated since 2006 and holds tier-1 bankable status, easing project financing for commercial installations and supporting favorable insurance terms.

Trade-offs
No efficiency edge over rivals

The AIKO Comet 2U (AIKO-G-MCH72Mw) matches the same 24.8% peak efficiency at the same 670 Wp power rating, so Tiger Neo III is no longer the clear efficiency leader within its comparable peer set.

Uneven product warranty across variants

Product warranty ranges from 12 to 25 years depending on the variant - lower-tier models in the series only carry a 12-year product warranty versus the flagship 25 years, requiring careful variant selection at purchase.

Notes from the database
  • Efficiency of 24.8% is 1.5pp above the N-type 650-700W median (23.3%)
  • At 248.0 W/m² power density, this panel generates 14.8 W/m² more per unit area than N-type 650-700W median (233.2 W/m²)
  • At -0.26%/°C (vs median -0.29%/°C), loses ~1% less power in hot conditions
  • At 32.5 kg, weight matches the N-type 650-700W median

Common questions

6 answered
What makes the TOPCon technology in Tiger Neo III different from standard PERC panels?
The N-type TOPCon cells used in the Tiger Neo III feature an additional passivation layer that reduces carrier recombination and lowers module degradation over time compared to conventional P-type PERC cells. As a result, the panel maintains higher energy yield throughout its service life, with lower first-year and long-term degradation than older cell technologies.
What is the maximum power output of the Jinko Tiger Neo III panel, and how many modules are needed for a typical 10 kWp installation?
Panels in the Tiger Neo III series reach a maximum power of up to 670 Wp. For a 10 kWp installation, roughly 15 modules from this series are sufficient, fewer than with older 400-450 W panels. The high power density reduces the roof area needed to reach a target installation capacity and lowers BoS costs for the mounting structure.
What warranty applies to the Tiger Neo III series?
Jinko Solar provides a 25-year product warranty and a 30-year power output warranty for the Tiger Neo III series. This means the manufacturer covers not only material and workmanship defects but also guarantees a specified level of energy performance over three decades, making this series one of the more bankable offerings on the market.
Are Tiger Neo III panels suitable for a pitched roof on a single-family home?
Yes, Tiger Neo III modules are a popular choice for residential installations on pitched roofs. The half-cut cell structure and multi-busbar interconnections increase resistance to microcracks that can occur during transport and installation, and the high per-panel power output allows more system capacity to fit on a limited pitched roof area.
How do Tiger Neo III panels perform on hot days and in low-light conditions?
The Tiger Neo III series has a low temperature coefficient of power, so it loses less efficiency during heat waves than older module generations when cell temperature rises above standard test conditions. N-type TOPCon technology also responds better to weak and diffuse light, resulting in more stable energy production on cloudy days and during early morning or evening hours.
Is Jinko Solar a tier 1 manufacturer, and can it be trusted for a long-term investment?
Yes, Jinko Solar is classified as a tier 1 manufacturer, meaning stable financial standing, high production volume, and a long-established global presence. This matters in practice for a 25-30-year warranty, as it increases the likelihood the manufacturer will be able to honor warranty claims throughout the system's service life, which is relevant for both residential and commercial investors.
