Q-CELLS Q.TRON BLK M-G2+ series was designed for maximized stable yields in real-world operating conditions - even under weaker sunlight, variable weather, and high temperatures. The key advantage is the N-type cell technology combined with the Q.ANTUM NEO, i.e., an optimized module structure that enhances light utilization and minimizes internal losses. This translates to more reliable energy production in the Polish climate, where energy generation isn’t just about peak summer performance but consistent output throughout the year.

In practice, this series addresses the needs of investors seeking stable power output over time. It helps with advanced anti-degradation protection (including Anti PID, Anti LeTID) and minimizes the risk of hot spots. The modules also feature high mechanical resistance to wind and snow loads, which is crucial for installations on roofs in challenging locations. Q.TRON BLK M-G2+ is an excellent choice for modern home installations and aesthetically pleasing roofs, thanks to its full black design and long, linear warranty coverage.

What owners get
High efficiency via N-type and Q.ANTUM NEO

N-type cells combined with Q.ANTUM NEO deliver up to 22.5% efficiency - matching JA Solar's JAM54D40 (22.5%) and clearly outperforming conventional PERC modules, translating into higher energy yield per unit of roof area.

Low power degradation over time

The manufacturer guarantees at least 98.5% of nominal power after year one, followed by a maximum 0.33% annual degradation, yielding at least 90.58% power retention at 25 years - meaningfully better than the typical 80.2% offered by conventional PERC modules with a 25-year linear warranty.

Favorable temperature coefficient

A power temperature coefficient of -0.29 to -0.30%/°C limits output losses in high heat, which is practically relevant on sun-exposed roofs in the Polish climate during summer.

Advanced degradation protection and Tier-1 manufacturer

Anti PID and Anti LeTID safeguards along with reduced hot-spot risk improve production stability over the module's lifetime, and the Tier-1/bankable status of the manufacturer (Hanwha Q-Cells, South Korea, founded 1999) simplifies project financing and provides confidence in warranty fulfillment.

Consistent 25-year product and power warranty

Q.TRON BLK M-G2+ offers a matched 25-year product and 25-year power warranty - unlike some competitors (e.g., JinkoSolar Tiger Neo 3.0), where the product warranty (12 years) is shorter than the power warranty (30 years), which can be confusing for buyers comparing offers.

Trade-offs
Power warranty shorter than some competitors

The 25-year linear power warranty is shorter than the 30-year performance warranties now offered by some N-type competitors, such as JA Solar DeepBlue (30 years) and JinkoSolar Tiger Neo 3.0 (30 years), which can be a drawback when comparing offers for long-horizon investments.

Efficiency below segment-leading models

The maximum efficiency of 22.5% is lower than Luxor Solar's ECO LINE N-TYPE TOPCon Non-Reflect (22.86%) at the same 440 Wp power class, meaning a somewhat lower yield per unit of area compared to the best-in-class competing offer.

Common questions

6 answered
What is the maximum power output of the Q-Cells Q.TRON BLK M-G2+ and how many cells does it have?
The top variant of the Q.TRON BLK M-G2+ series reaches 440 Wp, with the full lineup spanning 415 to 440 Wp. Each panel is built with 108 half-cut N-type TOPCon cells featuring the Q.ANTUM NEO layout, enabling module efficiency of up to 22.5%. Physical dimensions are 1722 × 1134 × 30 mm at a weight of 21.2 kg.
What is Q.ANTUM NEO technology in the Q.TRON BLK M-G2+ and how does it differ from older PERC modules?
Q.ANTUM NEO is Qcells' proprietary approach to N-type TOPCon cells. Unlike P-type PERC, TOPCon delivers a lower temperature coefficient of Pmax (−0.30 %/°C vs. a typical −0.35 %/°C for PERC) and significantly better resistance to LeTID and PID degradation. The result is improved energy yield during summer heat and reduced power loss over the full system lifetime.
Are the Q.TRON BLK M-G2+ panels well suited for climates with frequent cloud cover and low winter irradiance?
Yes. The N-type TOPCon technology combined with the Q.ANTUM NEO cell layout improves low-light and diffuse-irradiance performance typical of autumn and winter. The low temperature coefficient (−0.30 %/°C) also limits power loss on hot summer days, resulting in a more consistent energy harvest year-round — an important advantage in temperate climates with variable weather.
What warranties come with the Q-Cells Q.TRON BLK M-G2+ and what minimum power is guaranteed after 25 years?
The Q.TRON BLK M-G2+ series comes with a 25-year product warranty and a 25-year linear performance warranty. At least 98.5% of nominal power is guaranteed in year one, with a maximum annual degradation of 0.33% thereafter. After 25 years, the module must retain at least 90.58% of its rated output — one of the strongest linear performance warranties currently available on the market.
Can the Q.TRON BLK M-G2+ handle heavy snow loads and strong winds on residential rooftops?
Yes. The high-tech aluminum alloy frame is certified for snow loads up to 8,100 Pa (approx. 825 kg/m²) and wind loads up to 5,400 Pa, well above the requirements for most residential locations. The built-in Hot-Spot Protect technology also reduces the risk of cell damage caused by partial shading — for example, from snow accumulating at the module's lower edge.
Do the all-black Q.TRON BLK M-G2+ panels run hotter and lose more power because of their dark finish?
The black backsheet and black frame absorb marginally more heat than standard silver-frame modules, but the impact on energy output is minimal. This is offset by the N-type TOPCon technology's low temperature coefficient (−0.30 %/°C), which limits power loss as cell temperature rises. The Nominal Module Operating Temperature (NMOT) is 43 ± 3 °C, and the panel is rated for an operating range of −40 °C to +85 °C.
