Thanks to the use of **monocrystalline PERC technology and Half-Cell construction**, these modules achieve an impressive power range of 590-610W, making them an ideal choice for large commercial projects and solar farms. The use of larger wafers allows for a significant **reduction in BOS system costs**, as they generate more energy from a single panel, limiting the number of required mounting structures and cabling. The innovative division of cells in half effectively minimizes internal losses and improves efficiency in partial shading conditions, which directly translates into a more stable annual energy yield. This series stands out from the competition with an excellent balance between high efficiency and mechanical durability, offering a **low risk of micro-cracks** and better resistance to atmospheric loads. This solves the problem of limited roof space in industrial facilities, delivering maximum power where every dollar of investment saved counts. By choosing these modules, investors gain the certainty of a **high power fill factor**, which is key to optimizing return on capital in the utility-scale sector. These panels are the foundation of modern installations that focus on durability and long-term profit maximization. ## Notable figures - Efficiency of 21.0% matches the \*\*PERC 550-600W\*\* median - Power density of 210.2 W/m² matches the \*\*PERC 550-600W\*\* median - At -0.32%/°C (vs median -0.35%/°C), loses ~1% less power in hot conditions - Ranked #9696 out of 14005 panels for efficiency in the database ## Questions ### Is the Q-SUN Solar QNM210-HS-60 series still available for purchase? The QNM210-HS-60 series has been officially discontinued, meaning Q-SUN Solar has ended its production. It should not be used as the basis for system expansion plans. Individual units may still be available from distributors' warehouse stock, but supply will continue to diminish. Always check current inventory levels with your supplier before committing to this module for a new project. ### What warranty does the Q-SUN Solar QNM210-HS-60 module carry? The QNM210-HS-60 modules come with a 12-year product warranty covering material and workmanship defects, and a 25-year linear power output warranty. Over 25 years, the manufacturer guarantees that power degradation will not exceed defined thresholds, protecting long-term ROI. Note that given the discontinued status, warranty claim enforcement may become more difficult in the long run. ### How does the PERC half-cut cell technology in the QNM210-HS-60 series affect performance under partial shading? The half-cut cell design splits each PERC cell into two halves, reducing internal resistance and lowering the current flowing through the module. This minimizes resistive losses and heat buildup. Under partial shading conditions — such as a chimney or dormer — only a portion of the module loses output instead of the entire string, resulting in more stable annual energy yield compared to standard full-size cells. ### Are the QNM210-HS-60 modules with G12 210 mm cells suitable for large-scale solar farms? Yes, the QNM210-HS-60 series is designed for commercial and utility-scale PV projects. The G12 210 mm cells enable a peak output of up to 610 W per module, which means fewer panels and mounting structures are required per megawatt. This directly reduces BoS (Balance of System) costs and simplifies construction logistics for large ground-mounted installations. ### How does the monofacial design of the QNM210-HS-60 compare to bifacial modules — does it affect energy yield? The QNM210-HS-60 is a monofacial module, generating power only from its front surface. Bifacial modules additionally harvest light reflected from the ground, which on high-albedo ground-mounted systems can yield a few extra percentage points annually. On typical industrial rooftops or installations with limited ground reflectance, the difference is minimal, and monofacial system costs remain lower. ### How many QNM210-HS-60 panels are needed to build a 1 MW solar installation? At a peak power of 610 W per module, a 1 MW installation requires approximately 1,639 QNM210-HS-60 panels. Using the minimum rated power of 590 W, that number rises to around 1,695 units. The exact count depends on the power bin selected and the manufacturer's stated power tolerance. Always use datasheet specifications for the specific production batch when designing the system. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/QNM210-HS590-610-60-86cc78f36ea7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +50 W, cooler, +4.0 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.8 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, +3.8 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.6 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, +3.6 pp, +5 yr warranty | | [Q-SUN Solar QNM210-HG590-60](https://comparepv.com/panel/qn-solar-pv-limited-qnm210-hg590-60) | 590 W | Hotter, heavier, +5 yr warranty | | [Q-SUN Solar QNM210-HG600-60](https://comparepv.com/panel/qn-solar-pv-limited-qnm210-hg600-60) | 600 W | Hotter, heavier, +5 yr warranty | | [Q-SUN Solar QNM210-HG605-60](https://comparepv.com/panel/qn-solar-pv-limited-qnm210-hg605-60) | 605 W | Hotter, heavier, +5 yr warranty | | [Q-SUN Solar QNM210-HG610-60](https://comparepv.com/panel/qn-solar-pv-limited-qnm210-hg610-60) | 610 W | Hotter, heavier, +5 yr warranty | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +85 W, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +80 W, +2.8 pp, +5 yr warranty | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +75 W, cooler, +2.7 pp | | [Gamko New Energy GKA210N120-670](https://comparepv.com/panel/gamko-new-energy-gka210n120-670) | 670 W | +75 W, +2.7 pp, +5 yr warranty | | [Q-SUN Solar QN-665HJT-01](https://comparepv.com/panel/q-sun-solar-qn-665hjt-01) | 665 W | +70 W, cooler, +2.5 pp | | [Gamko New Energy GKA210N120-665](https://comparepv.com/panel/gamko-new-energy-gka210n120-665) | 665 W | +70 W, +2.5 pp, +5 yr warranty | | [Sunpro Power SPDG660-N120M12](https://comparepv.com/panel/sunpro-spdg660-n120m12) | 660 W | +65 W, +2.3 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/qn-solar-pv-limited-qnm210-hs595-60 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
