The Jinko Solar Tiger N-Type 66TR series is designed to maximize energy yield from the same roof or ground area - without the need to add additional modules. Its key advantage is the N-type TOPCon technology, which helps maintain high efficiency even in hot conditions and under weaker sunlight, while also minimizing typical power losses in older systems over time. In practice, this means more stable annual returns year after year and better investment profitability.

What sets it apart from many competitive panels is its half-cell construction, which improves the module's performance under partial shading (e.g., from a chimney, antenna, or tree). The use of Tiling Ribbon (TR) reduces the gaps between cells, translating to better light utilization and an aesthetically pleasing appearance. The series also employs multi busbar technology, which reduces electrical losses and supports long-term reliability.

The Tiger N-Type 66TR is an excellent choice for both residential and commercial installations, especially where every square meter counts and resilience to real-world conditions is crucial.

What owners get
N-type TOPCon cell technology

N-type TOPCon cells degrade at approximately 0.4% per year versus 0.7% for P-type PERC. LID is only 0.26% after 60 kWh/m² exposure compared to 1.92% for conventional PERC modules (TÜV NORD test data). This translates to measurably higher energy yield across the system's full lifetime.

30-year linear power warranty

Jinko guarantees a minimum 87.4% of nominal power output after 30 years, with annual degradation not exceeding 0.4%. The market standard in this segment is a 25-year power warranty - the Tiger N-Type 66TR extends coverage by 5 additional years, directly improving project LCOE.

Up to 21.74% efficiency - leads peer comparables

The JKM415N-6RL3 variant achieves 21.74% module efficiency, while direct peers in the same power class fall short: AE Solar AURORA AE MD-108 at 21.28%, LEDVANCE M395~415P54LM-BF-F3 at 21.25%, and Aptos Solar DNA 108-Monofacial at 21.25% - a gap of 0.46-0.49 percentage points. On a 30 m² rooftop this translates to measurably higher yield without adding extra modules.

Half-cut + Tiling Ribbon + multi busbar design

Half-cut cell splitting reduces circulating currents and improves shade tolerance. Tiling Ribbon (TR) technology minimizes inactive gaps between cells, increasing the active area fill factor. Multi busbar shortens the current path and lowers resistive losses, enhancing long-term electrical reliability.

Tier-1 BNEF manufacturer

Jinko Solar is a consistent Bloomberg NEF Tier-1 bankable manufacturer - a mandatory criterion for bank and fund financing of utility and commercial PV projects. Founded in 2006 and operating as one of the world's largest module suppliers, Jinko substantially reduces counterparty risk over the warranty horizon.

Trade-offs
Discontinued series (EOL 2022)

The Tiger N-Type 66TR was manufactured between 2020 and 2022 and is no longer in production. Availability is limited to distributor stock. System expansions after inventory depletion may be impossible to match with identical modules, creating mismatch issues in degradation profiles and I-V curves between module generations.

Monofacial only - no albedo gain

The panel has no bifacial capability (is_bifacial: false). Ground-mounted systems or installations with reflective substrates (gravel, concrete, snow) cannot capture rear-side irradiance. Peer comparable LEDVANCE M395~415P54LM-BF-F3 in the same power class offers a bifacial variant (BF designation), which under favorable albedo conditions adds 5-20% additional energy generation.

About the Tiger N-Type 66TR series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

Is the Jinko Solar Tiger N-Type 66TR series still available for purchase?
The Tiger N-Type 66TR series has been discontinued. Jinko Solar has shifted focus to newer product lines such as Tiger Neo. Some distributors may still carry remaining stock, but the selection of power variants is limited. If long-term service support and supply reliability are important to you, consider purchasing a current series from the same manufacturer.
What warranty does the Jinko Solar Tiger N-Type 66TR come with?
Jinko Solar provides a 25-year product warranty and a 30-year power output warranty. After 30 years of operation, the panel is guaranteed to retain at least 87.4% of its rated power. The extended power warranty is possible because N-type TOPCon cells degrade more slowly over time than older P-type PERC technology.
What is Tiling Ribbon (TR) technology and what does it change in the Tiger N-Type 66TR?
Tiling Ribbon is a cell interconnection method where electrical ribbons overlap the edges of adjacent cells, reducing the gaps between them. The larger active cell area within the same module footprint results in higher power output. In the Tiger N-Type 66TR, TR works alongside a 13-busbar (multi busbar) layout to minimize resistive losses and improve the long-term reliability of internal connections.
How well does the Tiger N-Type 66TR handle partial shading from a chimney or antenna?
Well. The half-cut cell design splits each cell into two halves, so shading on one part of the module reduces total output less than it would in conventional full-cell panels. In practice, shadows cast by chimneys, antennas, or tree branches cause smaller energy losses. This is a meaningful advantage on rooftops with complex shapes or multiple obstructions.
What is the efficiency of the Jinko Solar Tiger N-Type 66TR and how does it compare to PERC?
The 415 Wp variant achieves a module efficiency of approximately 21.7%, which is higher than typical P-type PERC panels from the same period (around 20-21%). The power temperature coefficient is -0.34%/°C, meaning less output loss in hot weather compared to PERC modules rated at -0.35% to -0.40%/°C. The result is higher energy yield during summer and heat waves.
Is the Jinko Solar Tiger N-Type 66TR a bifacial panel?
No, the Tiger N-Type 66TR is a mono-facial module - power is generated only by the front surface. Despite the absence of a bifacial design, N-type TOPCon cell technology delivers high efficiency and low annual degradation, making it well suited for standard rooftop installations where albedo gain from the ground surface would be negligible regardless.
