The use of 182-mm half-cut cells allows for a significant reduction in resistive losses and much better module performance in partial shading conditions. Thanks to **exceptional resistance to LID and LeTID degradation**, these components guarantee stable and predictable energy yields for decades, which directly translates into a faster return on investment. The module design enables efficient absorption of diffused light, which drastically increases total electricity production in less favorable weather conditions. This series perfectly addresses the problem of limited space on large-scale rooftops and ground-mounted farms, offering **maximum power density per square meter**. It is distinguished from the competition primarily by an excellent temperature coefficient, ensuring the panels work extremely efficiently even on hot days. This is a choice dedicated to demanding investors seeking the **lowest Levelized Cost of Energy (LCOE)** while maintaining the highest standards of mechanical resistance to extreme wind and snow loads. ## Notable figures - At 21.9% efficiency, this panel is 0.5pp below the \*\*TOPCon 550-600W\*\* median of 22.4% - 218.6 W/m² power density is 5.8 W/m² below \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - requires larger installation area - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - 28.3 kg weight - 2.9 kg lighter than \*\*TOPCon 550-600W\*\* median (31.2 kg), reducing installation effort - In the top 48% for efficiency among all TOPCon panels ## Questions ### What warranty does the Q-SUN Solar QNN182-HS-72 series come with? The QNN182-HS-72 series includes a 12-year product warranty covering manufacturing defects and a 30-year linear power output warranty. Over three decades, the manufacturer guarantees a minimum power level, which is essential for calculating the return on investment and LCOE of the system. Always review the detailed degradation thresholds in the warranty document before purchasing. ### How does TOPCon technology in the QNN182-HS-72 compare to older PERC panels? N-type TOPCon cells deliver higher conversion efficiency and significantly better resistance to LID and LeTID degradation than P-type PERC cells. In practice, the QNN182-HS-72 retains more of its rated power over its entire lifespan, directly lowering the LCOE of the installation compared to an equivalent PERC module. ### Do the Q-SUN QNN182-HS-72 panels perform well on hot summer days? Yes. The QNN182-HS-72 series features a favorable temperature coefficient, meaning it loses less power at elevated cell temperatures than typical PERC modules. This translates into higher energy output on hot, sunny days when conventional panels noticeably derate. The advantage stems from the N-type silicon used in TOPCon cell architecture. ### How many Q-SUN QNN182-HS-72 585W panels do I need for a 10 kW system? At a peak power of 585 W per module, you need 18 panels to reach approximately 10.5 kW DC. The exact count depends on the inverter's rated power and MPPT input range. Since 182 mm 72-cell modules have a larger footprint than residential panels, confirm available roof or ground area before finalizing the design. ### Is the QNN182-HS-72 series suitable for utility-scale ground-mount projects or only rooftops? The QNN182-HS-72 is designed for both large commercial rooftops and ground-mount solar farms. The high single-module power of up to 585 W and the 182 mm half-cut cell format maximize power density per square meter, reducing BoS costs for racking and cabling. As a monofacial module, it does not require a reflective ground surface to achieve its rated output. ### Is Q-SUN Solar a Tier 1 manufacturer, and does it matter when buying these panels? Q-SUN Solar is not classified as a Tier 1 manufacturer according to Bloomberg NEF rankings. For investors, this can mean that banks or leasing companies may require additional collateral when financing a project, and long-term warranty service availability may be less certain than with top-tier brands. Before purchasing, verify the company's current financial standing and warranty fulfillment process. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/QNN182-HS560-585-72-983fad652fbc.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.5 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -20 W, cooler, +2.4 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.3 pp | | [Q-SUN Solar QNM182-HG530-72](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hg530-72) | 530 W | -35 W, heavier, -1.4 pp | | [Q-SUN Solar QNM182-HS535-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs535-72) | 535 W | -30 W, -1.2 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS540-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs540-72) | 540 W | -25 W, -1.0 pp, -5 yr warranty | | [Q-SUN Solar QN-540HT](https://comparepv.com/panel/q-sun-solar-qn-540ht) | 540 W | Hotter, -1.1 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS545-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs545-72) | 545 W | Hotter, -0.8 pp, -5 yr warranty | | [Q-SUN Solar QN-545HT](https://comparepv.com/panel/q-sun-solar-qn-545ht) | 545 W | Hotter, -0.8 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS550-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs550-72) | 550 W | Hotter, -0.6 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/qn-solar-pv-limited-qnn182-hs565-72 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.
