Light for its output, no clear weak spot
The JT SNk(B) series comprises dual-glass photovoltaic modules built on heterojunction (HJT) technology, combining thin-film HJT layers with N-type monocrystalline silicon. Thanks to bifacial cells, these panels capture additional energy from light reflected onto the rear side of the module, resulting in noticeably higher energy yield compared to conventional single-sided designs. The design, based on HJT technology and a special anti-reflective glass, ensures stable performance even under low irradiance conditions - in the morning, evening, or on cloudy days - making the JT SNk(B) series particularly well suited to variable sunlight conditions. The panels also stand out for their very low temperature coefficient, limiting power losses on hot days, along with strong resistance to LID and PID degradation, translating into long-term stable energy production. A robust mechanical structure, rated to withstand snow loads up to 5400 Pa and wind loads up to 2400 Pa, makes them suitable for both rooftop installations and ground-mounted solar farms. Backed by a 30-year power output warranty with guaranteed degradation below 10%, the JT SNk(B) series is an attractive choice for investors seeking low LCOE and high reliability over a multi-decade investment horizon.
Ranking
Signals from the data
Commercial, utility-scale and hot-climate.
Top 22% of the HJT 500-550 W segment, against a median of 53.1.
Heterojunction (HJT) technology combined with N-type monocrystalline silicon delivers a very low temperature coefficient and strong resistance to LID and PID degradation, resulting in more stable energy output on hot days and over the module's operating lifetime compared to conventional PERC cells.
The dual-glass design with bifacial cells captures additional energy from reflected light on the rear side of the module, which is particularly valuable under variable irradiance conditions - mornings, evenings, and cloudy days.
A 30-year power warranty with degradation guaranteed below 10% clearly exceeds the 25-year industry standard offered by many tier-1 manufacturers, lowering LCOE over the long-term investment horizon.
Rated for snow loads up to 5400 Pa and wind loads up to 2400 Pa, the JT SNk(B) series is suitable for both rooftop installations and ground-mounted PV farms in demanding climatic conditions.
Jetion Solar has operated since 2004 and holds bankable tier-1 status, increasing manufacturer credibility and easing project financing for installations using this series.
Efficiency of 22.1-23% is lower than comparable 525 Wp modules such as the Jolywood JW-HD108N-R2 (23.6%) or Jinko Tiger Neo (23.61%), meaning a larger module footprint for the same power output and potentially higher BoS cost per kWp.
Compared with TOPCon-based peer comparables (VSUN, Jinko), HJT technology traditionally carries higher manufacturing costs, which can translate into a higher purchase price per Wp despite comparable or lower efficiency figures.
- At 23.0% efficiency, this panel is on par with typical HJT 500-550W modules
- Power density of 230.2 W/m² matches the HJT 500-550W median
- At -0.24%/°C, hot weather performance is typical for HJT 500-550W panels
- 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces
- In the top 14% for efficiency among all HJT panels
