Solid all-round for its segment
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.
Ranking
Signals from the data
Commercial, utility-scale and shaded-installations.
Half-cut monocrystalline N-type TOPCon cells combined with a dual-glass construction allow the module to capture additional energy reflected off the ground (albedo), which can boost energy yield by up to double digits versus monofacial modules on bright ground surfaces or roofs.
The manufacturer offers a linear 30-year power output warranty, matching the best-in-class offerings among dual-glass TOPCon bifacial modules and clearly exceeding the standard 25-year warranties found in some competing products, such as the Axitec AXIbiperfect GR WB.
The multi-busbar (MBB) cell structure reduces resistive losses and increases resistance to microcracks, meaningfully lowering the risk of power degradation during transport, installation, and long-term operation in large ground-mount plants.
Jetion Solar (founded in 2004) is listed on BloombergNEF's Tier 1 manufacturer list, confirming its modules have been financed by at least six independent commercial banks — reinforcing bankability for projects using the JT SNt(B) series.
Peak efficiency of 23% puts the series on par with leading peer comparables (Phono Solar Draco N-TOPCon at 23.02%, SunKean SKT440~460M12-96D4 at 23.02%) and clearly ahead of the Axitec AXIbiperfect GR WB (22.54%).
The 23.0% maximum efficiency is marginally lower than the top comparable TOPCon modules on the market — the Phono Solar Draco and SunKean SKT440~460M12-96D4 reach 23.02%. The gap is minor but could matter for roof-constrained projects seeking maximum power density.
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.
- At 22.8% efficiency, this panel is on par with typical TOPCon 450-500W modules
- At 227.7 W/m² power density, roof space requirements are typical for TOPCon 450-500W panels
- Temperature coefficient of -0.29%/°C matches the TOPCon 450-500W median
- 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces
- #2714 for efficiency, #2165 for temperature performance out of 14005 panels
