Middle of its segment, modest efficiency
Q-CELLS Q.TRON XL-G2 SERIES are modules designed for maximum yield from every square meter of installation-especially where the cost of energy over the long term is crucial. The series utilises N-type TOPCon (Q.ANTUM NEO) cells, resulting in excellent performance in real-world conditions, including low irradiance and temperature fluctuations. A key advantage is the bifacial double-glass construction-the module effectively utilises reflected light from the ground, enhancing yield without expanding the farm area.
In practice, the Q.TRON XL-G2 helps address typical design challenges: reduced BOS and cabling thanks to the high power of a single module, better production predictability, and lower risk of performance degradation over time. A critical element is the durability suite (including protection against PID, LeTID, and hot-spot), as well as the robust frame for various mounting systems, facilitating integration on trackers and ground structures.
This is the choice for C&I and PV farm installations where stable yield and low LCOE are priorities, rather than compromises common in many standard P-type modules.

Commercial and utility-scale.
Tight roof space, roofs where every square metre has to count and weight-limited structures.
Bottom 2% of the N-type 600-650 W segment, against a median of 22.77%. Ranked 7,022nd in the whole database.
Bottom 3% of the N-type 600-650 W segment, against a median of 227.7. Ranked 6,949th in the whole database.

N-type technology avoids the LID/LeTID degradation issues typical of older P-type PERC cells and performs better under low-irradiance and high-temperature conditions, translating into a real annual yield uplift versus PERC modules.
The manufacturer guarantees at least 98.5% of nominal power in year one with max. 0.33% annual degradation thereafter, yielding roughly 88.93% power retention at year 30 - stronger than the typical 25-year linear warranty with ~84% retention offered by many p-type competitors.
The module captures light reflected off the ground (albedo), boosting energy yield from the same footprint at no added land cost - a key advantage for utility-scale and C&I projects optimizing LCOE over a 25-30 year horizon.
Q-Cells (Hanwha Q Cells, founded 1999) is listed on BloombergNEF's Tier-1 list, easing project financing through banks and institutional lenders - an important factor for large-scale C&I and utility installations.
Power output up to 645 Wp at efficiency up to 23.1% reduces module count, cabling, and BOS costs for a given system size - on par with the best peer comparables (Runergy HY-DH156N8 at 645 Wp/23.1%).
The product (materials/workmanship) warranty is 12 years, while some tier-1 competitors offer 15-25 years of independent material defect coverage on top of the power warranty - worth factoring into service-risk planning for projects with a 25+ year horizon.
- Module efficiency of 21.8% is 1.0pp below average for N-type 600-650W panels (median: 22.8%)
- At 218.5 W/m², this panel generates 9.2 W/m² less per unit area than N-type 600-650W median (227.7 W/m²)
- At -0.30%/°C, hot weather performance is typical for N-type 600-650W panels
- At 35.4 kg (2.9 kg above N-type 600-650W median of 32.5 kg), requires checking roof load capacity
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
