Middle of its segment, modest efficiency
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.

Combining TOPCon technology with a glass-glass layout allows the module to capture light reflected from the ground surface, boosting energy yield without increasing footprint. Especially effective for ground-mount PV farms and installations with bright surroundings.
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.
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.
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 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.
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.
- At 21.8% efficiency, this panel is 1.0pp below the TOPCon 600-650W median of 22.8%
- 218.2 W/m² power density is 9.5 W/m² below TOPCon 600-650W median (227.7 W/m²) - requires larger installation area
- At -0.29%/°C, hot weather performance is typical for TOPCon 600-650W panels
- At 34.0 kg (1.2 kg above TOPCon 600-650W median of 32.8 kg), requires checking roof load capacity
- Bifacial design (85% factor) captures reflected light - adds 4-13% yield on ground-mount or white roof
