The use of **N-type solar cells in TOPCon technology** supports high efficiency and stable performance over time, while **double-glass construction** enhances resistance to moisture, microcracks, and harsh environmental conditions. This makes it a good choice in areas where competing modules degrade faster - particularly in open areas, near industrial sites, or in environments with high dust levels. Thanks to the **bifacial module**, Qrystal N8 can utilize reflected light from the ground, which significantly increases energy production in PV farms, carport structures, and flat-roof installations with reflective coverings. In practice, this means **lower BOS (Balance of System) costs** and easier budget closure without compromising quality. The series also features **enhanced resistance to PID (Potential Induced Degradation) and reduced hot-spot losses**, which facilitates predictable energy yields over the long term. ## Notable figures - At 22.6% efficiency, this panel is on par with typical \*\*N-type 550-600W\*\* modules - At 224.5 W/m² power density, roof space requirements are typical for \*\*N-type 550-600W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*N-type 550-600W\*\* median - Weight of 31.2 kg is 1.7 kg above \*\*N-type 550-600W\*\* median (29.5 kg) - verify structural support - Bifacial design (75% factor) captures reflected light - adds 4-11% yield on ground-mount or white roof ## Questions ### What warranty does the Q-SUN Solar Qrystal N8 come with, and what does a 30-year power warranty actually mean? The manufacturer provides a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty guaranteeing at least 87.4% of rated power output after 30 years. The N-type TOPCon cell technology exhibits lower annual degradation than conventional P-type PERC modules, making this warranty a realistic commitment rather than a marketing statement. ### What does it mean that the Qrystal N8 is bifacial, and how much extra energy can it produce? A bifacial module captures light from both the front and rear surfaces, harvesting energy from ground or rooftop albedo reflection. On utility-scale PV farms with a light-colored ground surface or in carport installations, the bifacial gain typically ranges from a few percent up to 25% additional annual yield. On a dark pitched roof the rear-side contribution is minimal, so the Qrystal N8 delivers its full potential primarily in ground-mount and flat-roof applications with a reflective surface. ### What is the efficiency of the Q-SUN Solar Qrystal N8, and how does it compare to competing modules? Depending on the power variant (565–585 W), module efficiency ranges from 21.9% to 22.6%. This is significantly above the market average for mass-produced panels — standard PERC modules typically achieve 20–21%. Higher efficiency translates directly into fewer modules and less roof or ground area required to reach the same system output, lowering BoS costs on constrained sites. ### How much does the Q-SUN Solar Qrystal N8 weigh, and does it require a reinforced mounting structure? The Qrystal N8 (565–585 W) weighs approximately 31.2 kg and measures 2278 × 1134 × 30 mm. The double-glass construction is heavier than conventional backsheet modules, so a structural assessment is recommended for older rooftops before installation. For ground-mount arrays and carports the additional load is generally not an issue, and the dual-glass design significantly extends the module's service life. ### Are the Q-SUN Solar Qrystal N8 panels suitable for harsh environments — heavy dust, humidity, or extreme temperatures? Yes. The double-glass construction eliminates the backsheet, which is susceptible to delamination and moisture ingress — a key advantage in dusty environments or near industrial sites. N-type TOPCon technology provides enhanced PID (Potential Induced Degradation) resistance. The low temperature coefficient of -0.29%/°C means smaller power losses during peak summer heat compared to typical PERC modules rated at -0.34 to -0.37%/°C. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/n-type-qrystal-mono-crystalline-qnht-6-565-585w-0-08-ad0100ed1795.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.0 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, cooler, +1.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -30 W, lighter, +1.8 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, lighter, +1.8 pp | | [Q-SUN Solar QNM182-HG530-72](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hg530-72) | 530 W | -50 W, hotter, -2.1 pp | | [Q-SUN Solar QNM182-HS535-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs535-72) | 535 W | -45 W, -1.9 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS540-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs540-72) | 540 W | -40 W, -1.7 pp, -5 yr warranty | | [Q-SUN Solar QN-540HT](https://comparepv.com/panel/q-sun-solar-qn-540ht) | 540 W | Hotter, lighter, -1.8 pp | | [Q-SUN Solar QNM182-HS545-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs545-72) | 545 W | -35 W, -1.5 pp, -5 yr warranty | | [Q-SUN Solar QN-545HT](https://comparepv.com/panel/q-sun-solar-qn-545ht) | 545 W | Hotter, lighter, -1.5 pp | | [Q-SUN Solar QNM182-HS550-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs550-72) | 550 W | Hotter, -1.3 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, lighter, +2.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, lighter, +2.0 pp | --- Source: https://comparepv.com/panel/q-sun-solar-qn-580ht-6 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.
