The JT SGh series combines proven Mono PERC technology with half-cut cells and multi-busbar (MBB) design, giving installers a module that performs reliably on both residential rooftops and larger commercial installations. Splitting the cells in half reduces resistive losses and lowers operating temperature in hot-spot conditions, translating into higher and more predictable energy yield throughout the panel's lifespan. The series stands out for its excellent low-light performance - it performs well in the early morning, evening, and on cloudy days, when many conventional modules lose efficiency. The round soldering ribbon design improves light capture and minimizes microcracks. The panel undergoes double electroluminescence (EL) inspection, and a sealed IP68 junction box provides a high level of moisture protection. A sturdy 35mm anodized aluminum frame and 3.2mm tempered glass deliver certified mechanical strength against wind, snow, and hail loads. Thanks to compatibility with systems up to 1500V DC, the module simplifies the design of longer string configurations, reducing BoS costs in larger installations. This is a solution for investors and installers seeking reliability, design flexibility, and stable performance under demanding weather conditions throughout the system's operating life.

What owners get
Efficiency on par with PERC segment leaders

Efficiency up to 21.3% matches the best comparable series (Goldi Solar GS10-B144-TF 21.3%, S-Energy SL65-72BGJ 21.3%, IBC Solar 182M 21.28%), placing JT SGh among the top-performing Mono PERC modules on the market.

Half-cut + MBB reduce losses and hot spots

Splitting cells into halves combined with a multi-busbar (MBB) design reduces resistive (Rs) losses and lowers hot-spot operating temperature, resulting in higher and more stable energy yield over the panel's lifetime.

Tier-1 manufacturer with a long track record

Jetion has been operating since 2004 and holds Tier-1 bankable status, reducing financing risk for investors and increasing confidence in warranty fulfillment.

Compatible with 1500V DC systems

The module supports system voltage up to 1500V DC, enabling longer strings and materially reducing BoS costs (cabling, inverters, protection equipment) in larger commercial installations.

Strong mechanical durability certifications

The panel is certified for 2400 Pa wind load, 5400 Pa snow load, and 25 mm hailstones at 82 km/h, and has passed double electroluminescence (EL) inspection with an IP68 junction box.

Trade-offs
PERC technology, not TOPCon/HJT

The series uses older Mono PERC technology, while newer N-type TOPCon modules offer lower LID/LeTID degradation and better high-temperature performance - by 2026 many Tier-1 manufacturers have shifted their premium lineup to TOPCon.

Warranty below new premium standards

12 years of product warranty and 25 years of power warranty are standard for PERC but noticeably lower than leading TOPCon modules currently on offer (often 15-25 years product and 30 years power).

No bifacial variant in this series

JT SGh is not a bifacial module (is_bifacial: false), forgoing the additional 3-8% yield from reflected irradiance available in comparable bifacial series from other manufacturers.

About the JT SGh series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is the maximum power output of Jetion JT SGh panels and how many cells do they use?
The JT SGh series reaches up to 550 Wp, achieved through Mono PERC technology combined with half-cut cells and a multi-busbar (MBB) design. Splitting cells in half reduces resistive losses and improves heat distribution across the panel surface, delivering higher efficiency per square meter of roof space.
What warranty comes with Jetion JT SGh panels?
The manufacturer offers a 12-year product warranty and a 25-year power output warranty. This covers both material and workmanship defects as well as the gradual decline in energy generation over time, giving investors predictable returns throughout the system's operating life.
Do Jetion JT SGh panels perform well in low light and cloudy conditions?
Yes, this is one of the series' key strengths. Thanks to half-cut cell technology and round soldering ribbons that capture diffuse radiation more effectively, the modules maintain higher efficiency in the morning, evening, and on cloudy days, when conventional panels lose significant output.
Are JT SGh panels suitable for large commercial installations with long strings?
Yes, the modules are compatible with systems up to 1500V DC, allowing designers to build longer string configurations and reduce the number of inverters and cabling required. This lowers BoS costs, making the series a strong fit for both rooftop and utility-scale PV installations.
How durable and well-built are Jetion JT SGh panels?
Every panel undergoes double electroluminescence (EL) inspection to catch hidden micro-cracks in the cells. The build is reinforced with a 35mm anodized aluminum frame and 3.2mm tempered glass, while an IP68-rated junction box protects against moisture. Modules are certified for wind, snow, and hail load resistance.
Is Jetion a Tier 1 manufacturer, and where are JT SGh panels made?
Yes, Jetion is listed as a Tier 1 manufacturer, reflecting financial stability and long-standing experience in PV module production. Panels are manufactured in China at facilities equipped with automated quality control lines, ensuring consistent performance across the entire JT SGh series.
