This ensures project financing eligibility and warranty security throughout the full 25-year power guarantee period. - **Efficiency up to 21.48% - above peer benchmark** - The top-tier variant reaches 21.48% STC efficiency, outperforming direct comparables: VDS-S144/FNH (20.4%), Sunket SKT410M10-108D4 (21.0%), and Luxor Eco Line N-type TOPCon (21.33%). Within the 410 Wp power class, Tiger 66TR ranks at the top of its segment. - **Multi Busbar + Hot 2.0** - Multi Busbar design reduces series resistance and improves current collection per cell, while Hot 2.0 suppresses LID and LETID degradation inherent to PERC cells. The result is more stable annual energy yield and lower risk of early power drop during the first months of operation. - **Harsh-environment resistance** - The series is certified for salt mist (IEC 61701 Class C), ammonia, and PID resistance, with structural ratings of 2400 Pa wind load and 5400 Pa snow load. It is well-suited for coastal rooftops, agricultural facilities, and industrial sites without additional protective measures. ## Cons - **Series discontinued (2023)** - Tiger 66TR reached end-of-production in 2023. New orders rely on residual distributor inventory, which limits availability of matching modules for system expansions and raises the risk of unavailable original replacements during warranty claims further into the system's lifetime. - **P-type PERC vs. N-type TOPCon peers** - P-type PERC technology carries higher long-term LID/LETID degradation than N-type TOPCon despite the Hot 2.0 mitigation layer. The series temperature coefficient (-0.34%/°C) lags behind typical N-type TOPCon modules (-0.29 to -0.30%/°C), translating to roughly 4-5% higher power loss at peak summer irradiance compared to competing N-type panels. - **12-year product warranty** - Current premium Tier-1 series (e.g., Jinko Tiger Neo, Luxor TOPCon in the same power class) ship with 15-year product warranties. Tiger 66TR's 12-year coverage reflects the 2019-era standard and offers less contractual protection against mechanical failures over a 25+ year rooftop installation lifetime. ## About this series The Jinko Solar Tiger 66TR series was designed for high installation performance in real-world conditions - not just in the laboratory. Its key advantage lies in combining N-type cells with refined interconnection architecture, resulting in more stable operation across a wide temperature range and better performance under weaker sunlight. Thanks to the **Multi Busbar technology**, the module collects current from the cells more efficiently, reducing losses and improving long-term reliability. Meanwhile, **Hot 2.0** aims to minimize degradation caused by light and temperature, helping maintain higher energy yields year after year. In practice, the Tiger 66TR addresses production drops during hot weather and the risk of faster module aging in demanding environments. The series also stands out for its **PID resistance** and **enhanced resistance to salt fog and ammonia**, making it suitable for coastal, agricultural, and industrial sites. This is a smart choice for rooftop installations and PV farms, where predictable yield and long-term reliability matter just as much as catalog specifications. ## Notable figures - At 20.4% efficiency, this panel is 1.0pp above typical \*\*PERC 0-400W\*\* modules (median: 19.4%) - Power density of 204.3 W/m² packs 10.1 W/m² more into the same footprint vs \*\*PERC 0-400W\*\* median (194.2 W/m²) - At -0.35%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - In the top 82% for efficiency among all PERC panels ## Questions ### Is the Jinko Solar Tiger 66TR series still available for purchase? The Jinko Solar Tiger 66TR series has been discontinued and is no longer actively manufactured. Some distributors may still have remaining inventory, but availability is very limited. If you need similar specifications with full warranty support, consider current Jinko Solar lineups such as Tiger Neo or Tiger Pro, which offer comparable or improved performance and active production backing. ### What warranty does the Jinko Solar Tiger 66TR come with? Jinko Solar Tiger 66TR panels include a 12-year product warranty covering manufacturing defects and workmanship, plus a 25-year linear power warranty guaranteeing at least 84.8% of rated output at the end of year 25. As a Tier 1 manufacturer, Jinko Solar provides additional confidence that warranty commitments will be honored by a financially stable, globally recognized company. ### Does the Jinko Solar Tiger 66TR perform well in hot summer conditions? The N-type cells used in the Tiger 66TR feature a low temperature coefficient of power at approximately -0.35%/°C, meaning less output drop on hot days compared to standard modules. The Hot 2.0 technology further reduces light-induced and temperature-induced degradation (LID/LETID), helping the module sustain higher energy yield year after year even in demanding thermal environments. ### What does Multi Busbar technology in the Tiger 66TR actually do, and is it worth it? Multi Busbar replaces a few wide busbars with many thin wires, shortening the current path across each cell and reducing resistive losses to improve module efficiency. Combined with Hot 2.0, which reduces LID and LETID degradation, the result is more stable energy output over the full service life. For a system operating 25 years, the cumulative difference in yield is measurable and justifies the technology. ### Are Jinko Solar Tiger 66TR panels suitable for coastal or agricultural environments? Yes, the Tiger 66TR series is certified for salt mist and ammonia resistance, making it well-suited for coastal installations and locations near livestock farms or cropfields. Appropriate sealing and protective materials guard the frame and junction box against corrosion in environments with elevated salt or organic compound concentrations. The series also offers strong PID resistance, which matters for grounded system configurations. ### What is the power output of the Jinko Solar Tiger 66TR and how many panels are needed for a 6 kWp home system? The top model in the Tiger 66TR lineup delivers a maximum power of 410 Wp. To build a common residential 6 kWp system, you would need approximately 15 modules. Each panel measures roughly 1855 x 1029 mm and weighs about 20.8 kg, fitting comfortably on a standard pitched roof without posing handling or mounting challenges for typical racking systems. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JKM390-410M-6RL3-V-F2-EN-ea8ef0ea2f8f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +50 W, cooler, +2.6 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -50 W, +2.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +2.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +2.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +2.6 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +2.6 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +50 W, cooler, +2.5 pp | | [Jinko Solar JKM395M-6RL3](https://comparepv.com/panel/jinko-solar-jkm395m-6rl3) | 395 W | +0.3 pp | | [Jinko Solar JKM400M-6RL3](https://comparepv.com/panel/jinko-solar-jkm400m-6rl3) | 400 W | +10 W, +0.5 pp | | [Jinko Solar JKM405M-6RL3-V](https://comparepv.com/panel/jinko-solar-jkm405m-6rl3-v) | 405 W | +15 W, +0.8 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +85 W, +3.6 pp, +15 yr warranty | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +75 W, cooler, +3.4 pp | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +80 W, +3.3 pp, +15 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +70 W, cooler, +3.1 pp | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | Cooler, +3.1 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/jinko-solar-jkm390m-6rl3 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
