Light for its output, no clear weak spot
Q-SUN Solar panels from the QNN182-HS-72 series with power outputs from 560 to 585W are an advanced solution based on N-type TOPCon cell technology, setting new efficiency standards in modern photovoltaic installations. 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.
Ranking
Signals from the data
Weight-limited structures.
Top 24% of the TOPCon 550-600 W segment, against a median of 53.8.
Efficiency up to 22.6% combined with 182 mm half-cut cell architecture reduces resistive losses and improves performance under partial shading, matching Risen's RSM144-9-560-585BNDG (22.6%) in the premium segment.
A 30-year power warranty places the series on par with leading competitors in the segment (e.g., Risen, Hanersun), a meaningful factor in LCOE calculations for commercial installations and ground-mount farms.
Modules rated up to 585W offer high power density per square meter, competitive with Hanersun's Hitouch 5N HN18-72H (585W, 22.65%) - useful where roof or ground space is limited.
No negative production tolerance reduces the risk of underestimating actual system output at the design stage, a standard expected for high-power TOPCon modules in this segment.
Q-SUN Solar (Qn-Solar, founded 2014) does not appear on the BloombergNEF Tier-1 list, unlike some competitors in this segment, which may complicate non-recourse financing for larger projects.
Maximum efficiency of 22.6% is 0.05 pp below Hanersun's Hitouch 5N HN18-72H and HiTouch 5N series (22.65% at the same 585W max power) - a marginal gap, but it affects positioning among peer comparables.
The QNN182-HS-72 series has no bifacial variant, whereas Qn-Solar's sister line QNN182-HG-72 (555-585W) is bifacial, limiting extra rear-side energy yield potential for ground-mount installations or high-albedo surfaces.
- Efficiency of 22.2% matches the TOPCon 550-600W median
- At 222.5 W/m² power density, roof space requirements are typical for TOPCon 550-600W panels
- Temperature coefficient of -0.30%/°C matches the TOPCon 550-600W median
- At 28.3 kg, this panel is 2.9 kg lighter than TOPCon 550-600W median (31.2 kg) - easier handling during installation
- Ranked #5817 out of 14005 panels for efficiency in the database
