The innovative **Q.ANTUM NEO** concept used in them allows for breaking the efficiency barriers encountered in traditional modules, resulting in significantly better utilization of the available roof area. This series was created for users who value impeccable aesthetics, offering an elegant **Full Black** finish that makes the installation an integral and discreet element of a modern building. Thanks to high resistance to degradation phenomena and excellent temperature parameters, these modules effectively solve the problem of power drops on hot days. This solution is dedicated primarily to demanding single-family home owners who expect **maximum energy yields** while maintaining the highest quality of workmanship. Compared to the competition, Q.TRON BLACK stands out with its **exceptional performance in low-light conditions**, which is key to optimizing system operation in the Polish climate zone. Investing in this series is a guarantee of stability and energy security, backed by rigorous quality control standards that exceed market norms, ensuring many years of trouble-free operation. ## Notable figures - Efficiency of 22.3% matches the \*\*N-type 400-450W\*\* median - 222.7 W/m² power density - 4.4 W/m² more than \*\*N-type 400-450W\*\* median (218.3 W/m²), more power per roof area - Temperature coefficient of -0.30%/°C matches the \*\*N-type 400-450W\*\* median - 20.9 kg weight - 1.1 kg lighter than \*\*N-type 400-450W\*\* median (22.0 kg), reducing installation effort - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What is Q.ANTUM NEO technology in the Q.TRON BLACK series and why does it matter? Q.ANTUM NEO is Q-Cells' proprietary N-type cell technology that advances beyond conventional PERC toward a TOPCon architecture. N-type cells feature lower light-induced degradation (LID) and a favorable temperature coefficient of -0.30%/°C, meaning the Q.TRON BLACK loses less power output on hot days compared to standard P-type modules. In practice, this translates into higher annual energy yields from the same roof area. ### Is the Q.TRON BLACK a bifacial panel — what does that mean for a residential installation? Yes, the Q.TRON BLACK is a bifacial module that generates electricity from both its front and rear surfaces. The rear side captures light reflected from the ground or rooftop surface (albedo effect), potentially boosting total energy output by several percentage points depending on surface type and color. On installations with lighter-colored roof surfaces the bifacial gain is especially pronounced. ### What warranties are included with the Q-Cells Q.TRON BLACK, and do they cover power degradation? The Q.TRON BLACK is backed by a 25-year product warranty and an exceptionally long 30-year linear power warranty. This means Q-Cells guarantees a specified percentage of nominal output power for three full decades of operation. As a Tier 1 manufacturer headquartered in South Korea, Q-Cells provides strong financial stability, which is an important safeguard for investors pursuing warranty claims. ### How does the Q.TRON BLACK perform on overcast and cloudy days typical in Central Europe? The Q.TRON BLACK series is engineered for strong low-light performance, which is critical in Poland where overcast and foggy days make up a substantial portion of the year. N-type Q.ANTUM NEO cells generate proportionally more energy under diffuse irradiance than older P-type PERC cells, resulting in better cumulative annual yields in the Central European climate zone. ### What is the peak power output of the Q.TRON BLACK and is it worth the premium over cheaper modules? The Q.TRON BLACK series reaches up to 445 Wp with efficiency exceeding 22%. Compared to cheaper P-type PERC modules, the Q.TRON BLACK offers a lower temperature coefficient (-0.30%/°C), a longer linear power warranty (30 years), and additional bifacial energy gain. For homeowners with limited roof space, these advantages frequently justify the higher upfront cost since more energy is harvested annually from the same number of panels. ### Do Q.TRON BLACK modules integrate well aesthetically on a sloped roof with dark roof tiles? Yes, the Q.TRON BLACK integrates seamlessly with dark roof tiles thanks to its Full Black finish — black frame, black backsheet, and black cells create a uniform, sleek appearance that blends into the building facade. The module is certified for snow loads up to 8100 Pa and wind loads up to 3600 Pa, meeting Polish building code requirements. Standard racking systems are fully compatible with these modules; no special mounting hardware is required. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/19e4563803abac121b585b52.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, cooler, +2.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, cooler, +2.2 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, cooler, +2.2 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, cooler, +2.0 pp | | [Q-Cells Q.TRON BLK S-G3R.12+ / BFG 435Wp](https://comparepv.com/panel/q-cells-q-tron-blk-s-g3r-12-bfg-435wp) | 435 W | -10 W, -0.5 pp | | [Q-Cells Q.TRON BLK S-G3R.12+ / BFG 440Wp](https://comparepv.com/panel/q-cells-q-tron-blk-s-g3r-12-bfg-440wp) | 440 W | -0.3 pp | | [Q-Cells Q.TRON S-G3R.12+ / BFG 450](https://comparepv.com/panel/q-cells-q-tron-s-g3r-12-bfg-450) | 450 W | Very close match | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +2.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/q-cells-q-tron-blk-s-g3r-12-bfg-445wp Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
