Efficiency up to 23.8% places the series on par with top peer comparables such as Sharp GSD8K66H (23.82%) and JA Solar JAM66D46 LB (23.8%). - **30-year linear power warranty** - The manufacturer covers the series with a 30-year power warranty, a premium standard exceeding the typical 25-year coverage of older PERC technology. Low LID/LETID degradation typical of N-type cells supports a more stable power decline curve over time. - **Reinforced double-glass construction** - Tempered double glass improves mechanical resistance against snow loads, wind, and hail impact, making the module a solid choice for installations in harsher climate conditions, both on rooftops and ground-mount projects. - **Double electroluminescence (EL) inspection** - Every module undergoes two EL inspections, reducing the risk of microcracks and manufacturing defects reaching the final installation - important for the series' long-term reliability. - **Reputable Tier-1 manufacturer** - Jetion Solar has operated since 2004 and appears on the BNEF Tier 1 list of PV module manufacturers, confirming project bankability and easing financing for installations using this series. ## Cons - **Series discontinued** - The JT SPt(B) series (launched in 2020) has been discontinued by the manufacturer. This means limited market availability, and potential difficulties with warranty service or sourcing identical modules when expanding an existing installation. - **Lower efficiency range trails segment leaders** - Variants closer to 710 Wp reach only 22.9% efficiency, below top peer comparables such as Sharp GSD8K66H (23.82%) or Tongwei TNC/THC (23.8%) offered at the same 740 Wp maximum power - the specific variant should be checked carefully when selecting modules. - **Product warranty shorter than power warranty** - The 12-year product warranty is notably shorter than the 30-year power warranty, which is typical for the segment, though some Tier-1 competitors now offer a standard 15-year product warranty on comparable specs. ## About this series The JT SPt(B) series consists of dual-glass monocrystalline modules built on **N-type TOPCon cells with a multi-busbar grid**, designed for installations that demand maximum energy yield within a limited mounting area. The defining feature of this series is its **bifacial technology**, which captures light reflected from the ground surface and delivers a real gain in energy production compared to conventional single-sided panels, directly lowering the levelized cost of electricity (LCOE). The N-type cell architecture reduces LID/LETID degradation and PID risk, allowing the modules to maintain stable output throughout their operating life. The tempered dual-glass construction boosts **mechanical durability** - the panels withstand heavy snow and wind loads as well as hail impact, making them a solid choice for installations in more demanding climates. Every module undergoes double electroluminescence (EL) inspection, minimizing the risk of microcracks and manufacturing defects. The JT SPt(B) series works well for both rooftop installations and larger ground-mounted projects, where **long-term reliability** and a predictable power output curve, backed by an extended manufacturer warranty, matter most. ## Notable figures - Efficiency of 22.9% matches the \*\*TOPCon 700-750W\*\* median - Power density of 228.6 W/m² matches the \*\*TOPCon 700-750W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 700-750W\*\* median - 36.7 kg weight - 1.3 kg lighter than \*\*TOPCon 700-750W\*\* median (38.0 kg), reducing installation effort - Bifaciality factor of 85% can add 4-13% extra yield with reflective mounting surface ## Questions ### Are Jetion JT SPt(B) panels still available for purchase? The JT SPt(B) series has been discontinued by Jetion and replaced by newer models. Remaining warehouse stock may still be available through distributors, but once depleted, identical modules will no longer be obtainable, which is worth considering when planning to expand an existing installation. ### What does bifacial technology offer in JT SPt(B) panels and is it worth the extra cost? Bifacial JT SPt(B) modules capture light hitting the rear side of the panel, reflected from the ground, roof, or a light-colored surface. In practice this delivers an additional energy yield of roughly several to a dozen percent compared to monofacial panels, without increasing the installation footprint. The extra cost makes most sense on bright ground surfaces such as gravel or white roofing, and in ground-mount or east-west installations. ### What is the maximum power output of the JT SPt(B) series panels? Top variants of the JT SPt(B) series reach a maximum power output of up to 740 Wp, placing them among high-power modules built on N-type TOPCon cells with a multi-busbar grid. This power level allows for higher energy yield per panel and reduces the number of modules needed to reach a target system capacity. ### What warranty comes with Jetion JT SPt(B) panels? The manufacturer backs the JT SPt(B) series with a 12-year product warranty and a 30-year linear power warranty guaranteeing limited performance degradation over time. This is a standard typical of modern N-type TOPCon modules and offers longer protection than classic PERC panels, where product warranties rarely exceed 10-12 years. ### How does TOPCon technology in JT SPt(B) differ from PERC panels in terms of durability? N-type TOPCon cells used in JT SPt(B) are less prone to LID and LETID degradation and carry a lower risk of PID effect compared to classic P-type PERC cells. As a result, the modules maintain their rated power for longer, translating into more stable energy yields throughout the system's lifetime. ### Are JT SPt(B) panels suitable for large ground-mount installations? Yes, thanks to their high unit power of up to 740 Wp, bifacial technology, and dual tempered glass that boosts mechanical strength, the JT SPt(B) series performs well in solar farm projects and larger ground-mount installations. The construction withstands snow, wind, and hail loads, and as a Tier 1 manufacturer, Jetion ensures quality confirmed by double electroluminescence (EL) inspection of every module. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ba4c15b567c640fd9c3ae4e470c4aa9d-83a31cbc0f0e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -30 W, lighter, +2.3 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -35 W, lighter, +2.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.1 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.0 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -40 W, lighter, +1.9 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -40 W, lighter, +1.9 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -40 W, lighter, +1.9 pp | | [Jetion JT715SLk(B)](https://comparepv.com/panel/jetion-jt715slk-b) | 715 W | Cooler | | [Jetion JT720SPt(B)](https://comparepv.com/panel/jetion-jt720spt-b) | 720 W | +10 W, +0.3 pp | | [Jetion JT725SLk(B)](https://comparepv.com/panel/jetion-jt725slk-b) | 725 W | +15 W, cooler, +0.5 pp | | [Jetion JT730SLk(B)](https://comparepv.com/panel/jetion-jt730slk-b) | 730 W | +20 W, cooler, +0.6 pp | | [Jetion JT735SLk(B)](https://comparepv.com/panel/jetion-jt735slk-b) | 735 W | +25 W, cooler, +0.8 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +95 W, heavier, +2.2 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +90 W, heavier, +2.0 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +85 W, heavier, +1.9 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +80 W, heavier, +1.7 pp | --- Source: https://comparepv.com/panel/jetion-jt710spt-b Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
