Especially effective for ground-mount PV farms and installations with bright surroundings. - **30-year linear power warranty** - The manufacturer guarantees power retention over 30 years, a premium standard among modern TOPCon modules that translates into lower LCOE over the module's lifetime compared to 25-year warranties on older PERC generations. - **Tier-1 bankability per BloombergNEF** - Jetion Solar, operating since 2004, is listed on the BNEF Tier 1 list, which facilitates project financing by banking institutions and reduces risk for large commercial investments. - **1500V system compatibility and IP68 sealing** - Support for up to 1500V system voltage lowers BoS costs and speeds up integration with modern inverters, while IP68 ingress protection ensures resistance to moisture and contamination in harsh climates. - **Half-cut cells and reinforced frame** - Half-cut cell technology reduces resistive losses and improves partial-shading tolerance, while the reinforced frame increases mechanical resistance to snow and wind loads - key for industrial and commercial installations. ## Cons - **Efficiency below top-tier peers** - The maximum efficiency of 22.9% trails competing 640W series such as Hanersun Hitouch 6N (23.3%) and Luxen LUXPOWER N5 (23.14%). At equal panel area this translates to slightly lower power output per square meter. ## About this series The Jetion JT SRt(B) 610-640W series consists of bifacial photovoltaic modules built on **N-Type TOPCon cells**, combining high conversion efficiency with low power degradation over the module's operating lifetime. The **half-cut** cell design reduces resistive losses and improves the panel's resilience to partial shading, resulting in more stable energy output under real-world installation conditions. The defining feature of this series is its **bifacial construction** in a glass-glass configuration, allowing the module to also capture light reflected off the ground and generate additional energy yield without increasing the installation footprint - a solution especially attractive for ground-mounted systems, utility-scale PV farms, and sites with bright or reflective surroundings. A **reinforced frame** combined with dual-glass encapsulation delivers strong mechanical resistance to snow and wind loads, while the sealed IP68 construction protects against moisture and contaminants even in demanding climates. JT SRt(B) modules are well suited for industrial and commercial installations as well as larger prosumer systems, where maximizing return per square meter of roof or ground space is a priority. Compatibility with system voltages up to 1500V allows these panels to integrate easily with modern inverters and mounting structures, helping lower BoS costs and shorten project deployment time. ## Notable figures - Efficiency of 22.5% matches the \*\*TOPCon 600-650W\*\* median - Power density of 225.4 W/m² matches the \*\*TOPCon 600-650W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 600-650W\*\* panels - At 34.0 kg, this panel is 1.2 kg heavier than the \*\*TOPCon 600-650W\*\* median (32.8 kg) - more demanding for installation crews - Bifaciality factor of 85% can add 4-13% extra yield with reflective mounting surface ## Questions ### How does N-Type TOPCon technology in Jetion JT SRt(B) panels differ from classic PERC cells? N-Type TOPCon cells offer higher conversion efficiency and lower power degradation over time compared to the previously dominant PERC cells. In practice, this means higher energy yield from the same surface area and more stable output after many years of operation, which directly affects investment payback given the 30-year power warranty. ### Does the bifacial design of Jetion JT SRt(B) panels deliver a real increase in energy production? Yes, the glass-glass construction allows the panel to also capture light reflected from the ground beneath it. The additional yield depends on the surroundings - ground-mounted installations and PV farms on bright or reflective surfaces, such as gravel or white membrane, benefit the most. This gain comes without increasing the installed footprint, only proper mounting height above ground. ### What type of installations are Jetion JT SRt(B) panels with up to 640 Wp best suited for? The high power output of up to 640 Wp combined with the bifacial design makes this series primarily suited for industrial, commercial, and larger prosumer systems as well as PV farms, where maximizing production per square meter of roof or ground is critical, rather than small residential installations on pitched roofs. ### What warranty comes with Jetion JT SRt(B) 610-640W panels? The manufacturer provides a 12-year product warranty and a 30-year power output warranty. This means that after 30 years, the panel should still generate the guaranteed percentage of its initial power as specified in the datasheet, which is a standard for modern modules using N-Type TOPCon cells. ### Are Jetion JT SRt(B) panels compatible with 1500V inverter systems? Yes, modules in this series are compatible with systems up to 1500V, allowing them to be connected in longer strings and reducing the number of inverters and cabling required. This lowers BoS (Balance of System) costs and shortens project completion time, especially in large-scale installations. ### Are Jetion JT SRt(B) panels resistant to harsh weather conditions such as snow and moisture? Yes, the reinforced frame and glass casing on both sides provide high mechanical strength against snow and wind loads. Additionally, the IP68-rated sealed construction protects the module's interior from moisture and contamination, which is important for installations in demanding climates. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/e4d0138ad18240938e4ced17f3a3d4f8-0b8345fe5b35.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +50 W, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +45 W, lighter, +2.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.5 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +45 W, cooler, +2.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +40 W, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +40 W, lighter, +2.3 pp | | [Jetion JT610SRt(B)](https://comparepv.com/panel/jetion-jt610srt-b) | 610 W | -20 W, -0.7 pp | | [Jetion JT615SRt(B)](https://comparepv.com/panel/jetion-jt615srt-b) | 615 W | -15 W, -0.5 pp | | [Jetion JT620SRt(B)](https://comparepv.com/panel/jetion-jt620srt-b) | 620 W | -10 W, -0.3 pp | | [Jetion JT625SRt(B)](https://comparepv.com/panel/jetion-jt625srt-b) | 625 W | Very close match | | [Jetion JT635SRt(B)](https://comparepv.com/panel/jetion-jt635srt-b) | 635 W | Very close match | | [Jetion JT640SRt(B)](https://comparepv.com/panel/jetion-jt640srt-b) | 640 W | +10 W, +0.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +70 W, cooler, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +65 W, cooler, +2.4 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, cooler, +2.3 pp | --- Source: https://comparepv.com/panel/jetion-jt630srt-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.
