Thanks to double-sided exposure, these modules can absorb radiation reflected from the ground, allowing for the **maximization of energy yields** even in less favorable lighting conditions. A key feature of the series is the use of Half-Cut and Multi-Busbar technology, which effectively reduces current losses and significantly increases tolerance to partial shading of the installation. The design based on **double tempered glass** guarantees excellent protection against degradation caused by moisture or chemical factors, making these panels an ideal choice for large-scale farms and demanding agro-photovoltaic projects. These panels solve the problem of premature system aging, offering **increased resistance to the PID phenomenon** and stable operating parameters for decades. They stand out from the competition with an optimized balance of system (BOS) costs, which directly translates into a faster return on investment for business clients. This is a solid solution for professionals seeking uncompromising durability and high power density while maintaining the highest standards of mechanical safety. ## Notable figures - Efficiency of 20.7% matches the \*\*PERC 500-550W\*\* median - Power density of 207.0 W/m² matches the \*\*PERC 500-550W\*\* median - -0.31%/°C temperature coefficient (median: -0.35%/°C) - retains ~2% more power at high temperatures - Weight of 31.4 kg is 3.0 kg above \*\*PERC 500-550W\*\* median (28.4 kg) - verify structural support - In the top 77% for efficiency among all PERC panels ## Questions ### Is the Q-SUN Solar QNM182-HG-72 series still available for purchase? The QNM182-HG-72 series has been officially discontinued by the manufacturer. Direct orders from Q-SUN Solar are no longer possible; however, some authorized distributors may still carry remaining warehouse stock. Before purchasing, contact local importers to confirm availability and current pricing. If stock is unavailable, consider newer Q-SUN Solar series with comparable specifications as a replacement. ### What warranty does the Q-SUN Solar QNM182-HG-72 series come with? Q-SUN Solar provides a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. The power warranty guarantees the module retains a specified minimum percentage of its rated output after 30 years of operation. These are competitive terms for bifacial PERC modules in the utility segment, though details should be confirmed with the local importer since the series is discontinued. ### Does the bifacial design of the QNM182-HG-72 actually deliver higher energy yields in practice? Yes. The bifacial monocrystalline PERC cells capture reflected irradiance (albedo) from the ground on the rear side in addition to direct front-side irradiance. On ground-mounted or agrivoltaic installations with reflective surfaces, energy yield gains of 5–15% over monofacial modules are achievable. Actual gain depends on ground albedo coefficient, module tilt angle, and clearance height above the surface. ### Do the Half-Cut and Multi-Busbar technologies in the QNM182-HG-72 series actually improve shading tolerance? Yes. Half-cut cell technology splits each PERC cell in half, reducing resistive losses and limiting the shading impact to only a portion of the module. The Multi-Busbar design shortens internal current paths and cuts transmission losses within the module. In practice, QNM182-HG-72 modules handle partial shading from chimneys, antennas, or nearby structures significantly better than older full-cell module designs. ### Are the Q-SUN Solar QNM182-HG-72 panels suitable for agrivoltaic and utility-scale ground-mounted projects? Yes, the QNM182-HG-72 530–550W series was designed for large-scale ground-mounted and agrivoltaic installations. The dual tempered glass construction protects modules against moisture, pesticides, and chemical agents common in agricultural environments. High per-module power output of up to 550W reduces the total module count per MW, directly lowering BoS costs and improving overall LCOE for commercial investors. ### What does enhanced PID resistance mean for the QNM182-HG-72 modules, and why does it matter? PID (Potential Induced Degradation) is a performance loss caused by voltage differentials between the cell and module frame, especially critical in large utility-scale farms operating at high system voltages. The QNM182-HG-72 series uses materials and manufacturing processes that suppress this effect, allowing the modules to maintain stable output over decades. The 30-year linear power warranty reflects the manufacturer's confidence in the long-term durability of this protection. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/QNM182-HG530-550W-72-9abe6c7e4db9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.8 pp | | [Q-SUN Solar QNM182-HG530-72](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hg530-72) | 530 W | Very close match | | [Q-SUN Solar QNM182-HS540-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs540-72) | 540 W | Hotter, lighter, -5 yr warranty | | [Q-SUN Solar QN-540HT](https://comparepv.com/panel/q-sun-solar-qn-540ht) | 540 W | Hotter, lighter, -5 yr warranty | | [Q-SUN Solar QNM182-HS545-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs545-72) | 545 W | Lighter, +0.4 pp, -5 yr warranty | | [Q-SUN Solar QN-545HT](https://comparepv.com/panel/q-sun-solar-qn-545ht) | 545 W | Hotter, lighter, -5 yr warranty | | [Q-SUN Solar QNM182-HS550-72](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs550-72) | 550 W | Lighter, +0.6 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +105 W, cooler, +4.1 pp | --- Source: https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hg535-72 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
