Space saver, weak in heat
The Q-SUN Solar QNM182-HS-60 photovoltaic panel series with a power range of 440-460W is an advanced solution based on N-type TOPCon cell technology, redefining efficiency standards in the rooftop installation segment. The use of 182 mm half-cells allows for a significant reduction in energy losses and minimizes the risk of hot-spots, translating into higher operational stability for the entire system. These modules are characterized by an exceptionally low temperature coefficient, making them an ideal choice for Polish climatic conditions, where variable sunlight and high summer temperatures often reduce yields. Thanks to the anti-reflective coating and high resistance to potential-induced degradation, investors gain confidence in long-term profitability. This series solves the problem of limited mounting space, offering maximum power density per square meter, which is crucial for single-family homeowners and small businesses. Compared to the competition, Q-SUN Solar QNM182-HS-60 stands out with its excellent low-light performance, generating energy efficiently even on cloudy days or during morning and evening hours. It is a solid foundation for a modern micro-installation, combining technical innovation with uncompromising mechanical durability for years.

Signals from the data
Residential, commercial, shaded-installations and hot-climate.
Hot climates.
Top 16% of the PERC 450-500 W segment, against a median of 208.5.
Top 17% of the PERC 450-500 W segment, against a median of 20.82%.
Bottom 2% of the PERC 450-500 W segment, against a median of -0.350. Ranked 13,081st in the whole database.
Splitting 182 mm cells into half-cut segments reduces resistive losses and hot-spot risk, improving module stability under partial shading conditions.
The 60-cell format using 182 mm cells delivers up to 460 Wp per panel, which is valuable for roof-space-constrained residential and small commercial installations.
The applied AR coating reduces reflection losses, which per manufacturer documentation translates into higher yields during morning, evening, and overcast conditions compared to standard PERC panels.
Selected cell materials and PERC construction provide good resistance to potential-induced degradation, limiting power loss under high humidity and high voltage-differential conditions in the array.
The standard 25-year power warranty aligns with typical PERC-segment market terms and provides a predictable degradation profile for investment financial modeling.
The series was discontinued just one year after launch (2022–2023), meaning limited availability of replacement units, warranty claim fulfillment, and service support over the 25-year power warranty horizon.
Q-SUN Solar (founded 2014) does not appear on BNEF Tier-1 bankability lists, which can complicate project financing through banks and increases risk for investors over a 25-year warranty period.
Maximum efficiency of 21.2% is notably lower than comparable 460 Wp modules based on N-TOPCon, such as Phono Solar Draco (23.02%) or SunKean SKT440~460M12-96D4 (23.02%), meaning more installed area is needed to reach the same installed capacity.
Unlike the competing Axitec AXIbiperfect GR WB (460 Wp, 22.54%), the QNM182-HS-60 series does not offer bifacial technology, forgoing the additional 5-10% yield achievable on reflective ground surfaces or flat-roof installations.
Promotional materials describe the series as built on N-type TOPCon cells, while the manufacturer's official datasheet indicates PERC technology — buyers should verify the current technical documentation before purchase to avoid confusion over actual panel specifications.
- At 21.2% efficiency, this panel is on par with typical PERC 450-500W modules
- 212.4 W/m² power density - 3.9 W/m² more than PERC 450-500W median (208.5 W/m²), more power per roof area
- -0.37%/°C temperature coefficient - 0.02pp worse than PERC 450-500W median (-0.35%/°C), expect higher hot weather losses
- #9076 for efficiency, #13081 for temperature performance out of 14005 panels
