The gap is minor but could matter for roof-constrained projects seeking maximum power density. - **12-year product warranty trails select competitors** - The materials and workmanship warranty is 12 years, while some Tier-1 manufacturers in the bifacial TOPCon segment already standardize on 15-year product warranties — a factor investors comparing total service-risk cost may weigh. ## About this series The **JT SNt(B)** series from Jetion Solar is a dual-glass module lineup built for installations that demand maximum durability and stable output over decades of operation. The panels rely on **bifacial TOPCon technology** paired with half-cut monocrystalline cells, capturing additional rear-side reflected light and meaningfully lowering the levelized cost of energy (LCOE) across the system's full lifecycle. The use of a **multi busbar (MBB) cell structure** reduces resistive losses and improves resistance to micro-cracks, resulting in greater reliability under the stresses of transport and installation. Unlike conventional backsheet modules, the dual-glass construction stands up far better to moisture, UV exposure, and repeated thermal cycling, which translates into noticeably slower power degradation over time. The JT SNt(B) series works equally well for rooftop installations and ground-mounted or commercial projects, where **high resistance to mechanical damage** and a long-term product warranty matter most. It's a solid choice for investors who expect low maintenance costs, consistent performance throughout the module's service life, and compatibility with the higher DC system voltages typical of large-scale solar farms. ## Notable figures - At 23.0% efficiency, this panel is on par with typical \*\*TOPCon 450-500W\*\* modules - At 230.2 W/m² power density, this panel generates 5.0 W/m² more per unit area than \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - Bifaciality factor of 85% can add 4-13% extra yield with reflective mounting surface - Ranked #1919 out of 14005 panels for efficiency in the database ## Questions ### How does the JT SNt(B) series differ from standard monofacial Jetion panels? The key difference is the glass-glass (double-glass) construction combined with bifacial TOPCon cells. The panel recovers additional energy reflected from the ground, increasing energy yield by up to several percent compared to classic backsheet modules. The glass on both sides also better protects the cells from moisture and degradation, resulting in a longer system lifespan. ### What warranty comes with the JT SNt(B) panels? Jetion offers a 12-year product warranty and a 30-year linear power output warranty. This means the manufacturer commits to maintaining a defined performance level over three decades of operation, which is standard for premium-class bifacial modules and reflects confidence in the durability of the double-glass construction. ### Are JT SNt(B) panels suitable for large-scale solar farms? Yes, the JT SNt(B) series, with power output up to 460 Wp, is compatible with elevated DC voltage systems typical of commercial and ground-mount installations. The high mechanical resistance of the double-glass construction and stable long-term productivity make it well suited for projects requiring low maintenance costs and predictable LCOE. ### What is TOPCon technology and why is it better than PERC? TOPCon (Tunnel Oxide Passivated Contact) is a monocrystalline cell technology that delivers higher efficiency and lower recombination losses than older PERC technology. In practice, this means higher power output from the same panel area and better performance at high temperatures, which matters in summer when panels heat up on the roof. ### How much extra energy does bifaciality add in JT SNt(B) panels? The actual gain from bifaciality depends on ground albedo, mounting height, and tilt angle, but under typical conditions (light-colored ground, gravel, white roofing) you can expect an additional 5-15% energy yield compared to a monofacial panel. The best results are achieved with ground-mount or carport installations, where the rear side has unobstructed access to reflected light. ### Does the MBB multi-busbar structure in JT SNt(B) improve panel durability? Yes, the multi-busbar (MBB) structure reduces the distance between conductive paths on the cell, lowering resistive losses and distributing mechanical stress across more connection points. This makes the cells less prone to microcracks during transport, installation, and cyclic thermal loading, directly reducing power degradation over time. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/062f1e154b304c4aa6a26bdeeb67a5d1-3e168e3b660a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, cooler, +1.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, cooler, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, cooler, +1.5 pp | | [Jetion JT440SNt(B)](https://comparepv.com/panel/jetion-jt440snt-b) | 440 W | -20 W, -1.0 pp | | [Jetion JT445SNt(B)](https://comparepv.com/panel/jetion-jt445snt-b) | 445 W | -15 W, -0.7 pp | | [Jetion JT450SNt(B)](https://comparepv.com/panel/jetion-jt450snt-b) | 450 W | -10 W, -0.5 pp | | [Jetion JT455SNt(B)](https://comparepv.com/panel/jetion-jt455snt-b) | 455 W | Very close match | --- Source: https://comparepv.com/panel/jetion-jt460snt-b Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
