The JT SXt(B) series consists of dual-glass monocrystalline modules engineered for installations that demand maximum durability and stable energy yield over decades of operation. The use of N-type TOPCon cells with multi-busbar technology delivers high conversion efficiency while reducing resistive losses, translating into genuinely higher energy production under partial shading or elevated operating temperatures. Thanks to bifacial energy harvesting, the panels also capture light reflected from the ground, boosting total yield by up to roughly twenty percent compared to monofacial designs, which directly lowers the project's LCOE. The dual-glass construction eliminates the risk of PID degradation and provides better mechanical resistance and longer service life than conventional backsheet panels. The modules undergo double full EL inspection, minimizing the risk of hidden cell microcracks. The series also stands out for its high resistance to snow, wind loads, and hail impact, making it well suited to demanding climatic conditions. This is a solution built for solar farms and large commercial installations, where low failure rates, predictable long-term power degradation, and maximizing revenue per square meter of roof or ground space are essential.

What owners get
N-type TOPCon cells with multi-busbar

N-type TOPCon cells reduce resistive losses and LID degradation compared to older P-type PERC technology, delivering module efficiency up to 23.7% and more stable output at elevated operating temperatures.

Dual-glass bifacial construction

Bifacial dual-glass design eliminates PID degradation risk and can boost total energy yield by roughly 10-25% versus monofacial backsheet panels, directly lowering the project's LCOE.

30-year linear power warranty

The manufacturer offers a 30-year power warranty alongside a 12-year product warranty, matching premium-segment standards for utility-scale plants and commercial installations where predictable power degradation is critical.

Double EL inspection and Tier-1 status

Modules undergo double full EL inspection to minimize hidden micro-crack risk, and Jetion is a Tier-1 (bankable) manufacturer founded in 2004, adding supplier credibility for large-scale project financing.

High mechanical load resistance

The dual-glass build provides greater resistance to snow, wind, and hail loads compared to conventional backsheet panels, suiting the series for harsh climate conditions.

Trade-offs
Efficiency trails top competitors

Maximum efficiency of 23.7% lags comparable Tier-1 models: AIKO Stellar 2N+78 reaches 25.1%, Gokin GK-4-78HGBD 24.3%, and Gamko GKA210N132 24.14% - a gap of 0.4-1.4 percentage points that can translate into lower installed capacity for the same roof area.

Series discontinued

The JT SXt(B) series has been discontinued, meaning limited availability of service support, spare/matching modules, and difficulty sourcing identical panels for future system expansion or warranty claims.

Notes from the database
  • Module efficiency of 23.5% is 0.6pp below average for TOPCon 750-800W panels (median: 24.1%)
  • 235.1 W/m² power density is 6.3 W/m² below TOPCon 750-800W median (241.4 W/m²) - requires larger installation area
  • Temperature coefficient of -0.29%/°C matches the TOPCon 750-800W median
  • At 40.0 kg, this panel is 1.7 kg heavier than the TOPCon 750-800W median (38.3 kg) - more demanding for installation crews

Common questions

6 answered
Is the Jetion JT SXt(B) series still available for purchase?
The JT SXt(B) series has been discontinued from current production and replaced by newer models in Jetion's lineup. Panels may still be available from distributors as remaining stock, but it's worth confirming current availability and production date with the seller, since stock of specific power ratings and batches is limited.
How does the TOPCon technology used in JT SXt(B) differ from classic PERC cells?
N-type TOPCon cells feature an additional passivation layer that reduces carrier recombination, delivering higher conversion efficiency than standard P-type PERC cells. In practice, this means higher energy yield per roof area, lower losses at elevated operating temperatures, and slower power degradation over time.
How much extra energy does the bifacial design of JT SXt(B) actually deliver?
Thanks to the dual-glass construction and bifacial technology, JT SXt(B) panels also capture light reflected from the mounting surface. Depending on ground albedo and installation height, this can boost total energy yield by roughly ten to over twenty percent compared to monofacial panels of the same nominal power.
What warranty comes with Jetion JT SXt(B) panels?
Jetion provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty guaranteeing a minimum production level throughout that period. This is one of the longer warranty terms available among dual-glass modules on the market.
Are JT SXt(B) panels suitable for large-scale solar farm installations?
Yes, the JT SXt(B) series, with power ratings up to 800 Wp, was designed primarily for large commercial installations and solar farms. The dual-glass construction eliminates PID degradation risk, and high resistance to snow, wind, and hail loads makes these panels well-suited to demanding utility-scale conditions.
Are JT SXt(B) modules resistant to cell microcracks and manufacturing defects?
Every panel in the JT SXt(B) series undergoes double full EL (electroluminescence) inspection, allowing cells with hidden microcracks to be detected and rejected before shipping. The dual-glass construction also provides greater mechanical rigidity and better cell protection than back-sheet panels.
