**N-type TOPCon cell technology** - TOPCon cells deliver lower LID/LeTID degradation and better high-temperature performance than older PERC cells, translating into higher annual yield under Polish climate conditions. - **Bifacial design with up to 30% gain** - The double-glass bifacial construction captures reflected (albedo) light on the rear side, which depending on the mounting surface can boost energy output by up to 30% compared to monofacial modules. - **Extended 30-year power warranty** - The manufacturer offers a 30-year linear power warranty alongside a 25-year product warranty - longer than the standard 25/25-year terms found in many competing N-type series, including some peers such as Sunova Tangra S Pro HD. - **High PID resistance and low temperature coefficient** - The construction limits potential-induced degradation (PID) losses and localized overheating, improving production predictability during summer when module temperatures rise. - **Full Black aesthetics without sacrificing performance** - The uniform dark finish (black cells, frame, and backsheet) combines visual appeal for residential rooftops with 21.5-22.5% efficiency, in line with modern N-type modules. ## Cons - **Efficiency trails segment leaders** - Peak efficiency of 22.5% falls short of comparable N-type models, e.g. SunKean/Sunket New Energy SKT430~450M10-108D5 reaching 23.04% at the same 450 Wp power - a gap of about 0.5 pp against Qrystal N8. - **No BNEF Tier-1 (bankable) status** - Q-SUN Solar does not appear on the BNEF Tier-1 manufacturer list, meaning there's no documented track record of non-recourse commercial bank financing - this may limit access to preferential project financing compared to Tier-1 brands. - **Relatively short market track record** - Q-SUN Solar was founded in 2014, giving it a shorter documented history than established Tier-1 PV players - a factor some institutional investors weigh when assessing long-term reliability of 25/30-year warranty claims. ## About this series The Q-SUN Solar Qrystal N8 (Full Black) series is designed for installations where both aesthetics and stable energy production over the long term are important. These modules feature a sleek, uniformly dark aesthetic that complements modern roofs and facades without creating unwanted reflections or contrasting elements. In practice, they stand out due to their **N-type cell with TOPCon technology**, which helps maintain high efficiency even under less than ideal conditions - in extreme heat, with variable sunlight, and during periods of poor weather. The design also supports **PID resistance** and minimizes losses associated with localized overheating, making the system more predictable in daily operation. Another advantage is **low temperature sensitivity**, which translates to better performance in the summer in Polish conditions. This is a good choice for investors who want **full black** panels for their homes, installations with high visual requirements, or projects where quality and durability are prioritized over fleeting trends. ## Notable figures - At 22.0% efficiency, this panel is on par with typical \*\*N-type 400-450W\*\* modules - Power density of 220.2 W/m² matches the \*\*N-type 400-450W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*N-type 400-450W\*\* panels - At 25.0 kg, this panel is 3.0 kg heavier than the \*\*N-type 400-450W\*\* median (22.0 kg) - more demanding for installation crews - In the top 47% for efficiency among all N-type panels ## Questions ### What warranty does Q-SUN Solar offer on the Qrystal N8 Full Black panels? Q-SUN Solar provides a 25-year product warranty and a 30-year linear power output warranty on the Qrystal N8 series. The power warranty guarantees a specified minimum performance level throughout the entire period, giving homeowners a solid basis for calculating ROI and projecting system output across the full lifecycle — one of the longer warranty standards in the residential PV market. ### Do Q-SUN Solar Qrystal N8 Full Black panels perform well in summer heat? Yes. The N-type TOPCon cells in the Qrystal N8 carry a temperature coefficient of Pmax at -0.29%/°C, which is among the lowest in this product class. In practice, when a panel heats up to 60-70°C on a hot summer day, it loses less power than a conventional P-type PERC module. Under central European summer conditions, this translates into measurably better energy generation during peak heat months. ### Since the Qrystal N8 is Full Black, does its bifacial design actually matter? It is a fair question. The module uses a double-glass bifacial structure that technically captures rear-side irradiance, but the dark back surface reduces that gain compared to a white backsheet version. The real advantage here is durability: double glass delivers superior moisture resistance, reduced micro-crack risk, and slower laminate degradation. Over the 25-30 year warranty horizon, those structural benefits outweigh any short-term albedo gain. ### Are the Qrystal N8 panels resistant to PID, and does it matter in central European climates? Yes, the Qrystal N8 series features strong PID (Potential Induced Degradation) resistance. In Poland, high autumn and winter humidity combined with variable system voltages creates conditions favorable to PID, which causes gradual and hard-to-detect output losses. N-type TOPCon cells are inherently more PID-resistant than P-type PERC due to their oxide passivation layers, resulting in more predictable long-term generation. ### What is the rated power of the Q-SUN Solar Qrystal N8, and how many panels are needed for a home system? The Qrystal N8 tops out at 450 Wp per module. A typical residential 5-10 kWp system requires between 12 and 22 panels. Each module measures 1,762 x 1,134 mm and weighs 25 kg, which is within standard structural load limits for single-family residential rooftops. The footprint is compatible with most commonly used rail-mounting systems for pitched roofs. ### Does the Q-SUN Solar Qrystal N8 Full Black blend well visually with a modern sloped roof? Yes, this series was designed for installations where aesthetics matter as much as performance. The uniformly black panel surface, frame, and backsheet eliminate contrasting elements and unexpected reflections common with standard modules. The panels integrate naturally with graphite or anthracite-toned roofs. The 1,762 x 1,134 mm module format is compatible with most standard mounting systems used on sloped residential rooftops. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/n-type-qrystal-full-black-mono-crystalline-qnht-5-430-450w-abff50d5678e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, lighter, +2.5 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, lighter, +2.5 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, lighter, +2.3 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, lighter, +2.3 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, lighter, +2.3 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, lighter, +2.3 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, cooler, +2.3 pp | | [Q-SUN Solar QN-430HT-5](https://comparepv.com/panel/q-sun-solar-qn-430ht-5) | 430 W | -10 W, -0.5 pp | | [Q-SUN Solar QN-435HT-5](https://comparepv.com/panel/q-sun-solar-qn-435ht-5) | 435 W | Very close match | | [Q-SUN Solar QN-445HT-5](https://comparepv.com/panel/q-sun-solar-qn-445ht-5) | 445 W | +0.3 pp | | [Q-SUN Solar QN-450HT-5](https://comparepv.com/panel/q-sun-solar-qn-450ht-5) | 450 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +3.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, lighter, +2.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +60 W, lighter, +2.5 pp | --- Source: https://comparepv.com/panel/q-sun-solar-qn-440ht-5 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
