The use of a durable **Double Glass** construction makes the panels exceptionally resistant to extreme weather conditions, such as high humidity, ammonia exposure, or heavy mechanical loads, which directly translates into an extended lifespan of the entire installation. Thanks to the full utilization of **bifacial technology**, these modules effectively generate additional energy from reflected radiation reaching the rear side of the cells. It is an ideal solution for projects where the priority is maximizing yields per unit area, especially when mounted on bright surfaces or ground-mounted structures. An exceptionally low temperature coefficient guarantees stable power production even on very hot days, clearly distinguishing this series from standard components that lose power at high temperatures. These modules are mainly dedicated to **large-scale solar farms** and demanding commercial investments aiming to optimize the LCOE index. By choosing this solution, investors receive equipment with the highest resistance to the PID effect, optimized for stable operation over decades, ensuring the financial security of every investment. ## Notable figures - Efficiency of 22.1% matches the \*\*TOPCon 550-600W\*\* median - At 220.6 W/m², this panel generates 3.8 W/m² less per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - In the top 43% for efficiency among all TOPCon panels ## Questions ### Is the Q-SUN Solar QNN182-HG-72 series still available for purchase? The Q-SUN Solar QNN182-HG-72 series has been discontinued and is no longer available as a new product. If you need to expand an existing installation using these modules, contact distributors to check warehouse stock. For new projects, we recommend selecting a currently active TOPCon module line from a manufacturer with an active service and warranty network. ### What warranty does the Q-SUN Solar QNN182-HG-72 come with? The QNN182-HG-72 series carries a 12-year product warranty covering material and manufacturing defects, along with a 30-year linear power output warranty guaranteeing stable energy yield over three decades of operation. Investors should note that Q-SUN Solar is not listed as a Tier 1 manufacturer, a factor worth considering when assessing the long-term financial risk of the investment. ### What is TOPCon cell technology used in the QNN182-HG-72 and is it worth the premium? TOPCon (Tunnel Oxide Passivated Contact) relies on N-type cells that eliminate LID (Light-Induced Degradation) common in legacy P-type modules. The result is higher initial efficiency and a slower power decline over the years. In the QNN182-HG-72, this translates to a maximum output of 585 Wp and an exceptionally low temperature coefficient, meaning smaller power losses on hot days compared to standard PERC modules. ### How does the bifacial feature work in the QNN182-HG-72 and when does it pay off? Bifacial technology allows the QNN182-HG-72 to generate electricity from both the front and rear surfaces by capturing light reflected from the ground. The highest bifacial gain is achieved on light-colored surfaces such as sand, concrete, or white membranes, with adequate ground clearance. On utility-scale PV farms, bifacial modules can increase annual energy yield by 5–15% compared to a monofacial module of the same rated power. ### Does the Double Glass construction in the QNN182-HG-72 genuinely extend system lifespan? Yes, dual-glass lamination removes the backsheet as a potential failure point, significantly improving resistance to humidity, ammonia from fertilizers, and mechanical loads from snow and wind. This is especially valuable in agrivoltaic and ground-mounted installations exposed to harsh conditions. The glass rear panel also limits moisture ingress, directly reducing the risk of cell degradation throughout the module's service life. ### What projects are the Q-SUN Solar QNN182-HG-72 modules designed for — can they be used on a residential roof? The QNN182-HG-72, rated at 585 Wp in a 72-cell format, is engineered for utility-scale PV farms and commercial projects focused on LCOE optimization. The large dimensions and weight typical of 72-cell modules make them impractical for residential rooftops, where smaller 60- or 66-cell modules are the standard choice. For residential prosumer installations, a smaller, lighter module is strongly recommended. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/QNN182-HG565-585-72-d3c36b5556c5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 15 kg lighter, +2.3 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.3 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.3 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.1 pp | | [Q-SUN Solar QNM182-HG530-72](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hg530-72) | 530 W | -40 W, hotter, -1.6 pp | | [Q-SUN Solar QNM182-HS535-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs535-72) | 535 W | -35 W, -1.4 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS540-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs540-72) | 540 W | Lighter, -1.2 pp, -5 yr warranty | | [Q-SUN Solar QN-540HT](https://comparepv.com/panel/q-sun-solar-qn-540ht) | 540 W | Lighter, -1.3 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS545-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs545-72) | 545 W | Lighter, -1.0 pp, -5 yr warranty | | [Q-SUN Solar QN-545HT](https://comparepv.com/panel/q-sun-solar-qn-545ht) | 545 W | Lighter, -1.0 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS550-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs550-72) | 550 W | Lighter, -0.8 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +80 W, lighter, +3.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +75 W, lighter, +2.9 pp | --- Source: https://comparepv.com/panel/qn-solar-pv-limited-qnn182-hg570-72 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.
