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.

What owners get
Half-cut cell design

Splitting 182 mm cells into half-cut segments reduces resistive losses and hot-spot risk, improving module stability under partial shading conditions.

High power density per m²

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.

Anti-reflective coating and good low-light performance

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.

Strong PID resistance

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.

25-year linear power warranty

The standard 25-year power warranty aligns with typical PERC-segment market terms and provides a predictable degradation profile for investment financial modeling.

Trade-offs
Production discontinued in 2023

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.

Manufacturer lacks Tier-1 status

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.

Lower efficiency than N-TOPCon competitors

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.

No bifacial variant

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.

Mismatch between marketing copy and datasheet

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.

Notes from the database
  • Efficiency of 21.0% matches the PERC 450-500W median
  • At 210.1 W/m² power density, roof space requirements are typical for PERC 450-500W panels
  • -0.37%/°C temperature coefficient - 0.02pp worse than PERC 450-500W median (-0.35%/°C), expect higher hot weather losses
  • #9758 for efficiency, #13081 for temperature performance out of 14005 panels

Common questions

6 answered
Is the Q-SUN Solar QNM182-HS-60 series still available for purchase?
The QNM182-HS-60 series has been discontinued by Q-SUN Solar and is no longer manufactured. Some distributors may still carry warehouse stock, but availability is limited. Before ordering, confirm stock levels with your dealer and clarify who handles warranty claims — the regional importer or Q-SUN Solar directly. For new installations, we recommend considering currently produced series with comparable or improved specifications.
What warranty does the Q-SUN Solar QNM182-HS-60 carry?
Q-SUN Solar provides a 12-year product warranty covering material defects and workmanship, alongside a 25-year linear power output warranty. The power warranty guarantees the module retains a specified percentage of its rated output over 25 years. Since this series is discontinued, verify with your distributor whether warranty claims are processed by the local importer or directly by Q-SUN Solar before committing to a purchase.
What cell technology does the QNM182-HS-60 use and what does it mean for system performance?
The QNM182-HS-60 series uses PERC (Passivated Emitter and Rear Cell) technology with 182 mm half-cut cells. Rear surface passivation reduces charge carrier recombination, yielding higher efficiency than standard monocrystalline cells. The half-cut design lowers operating current, which minimizes resistive losses, reduces hot-spot risk, and improves performance under partial shading conditions such as chimneys or roof dormers.
How do QNM182-HS-60 panels perform during winter and on overcast days in Poland?
The QNM182-HS-60 series handles Poland's variable climate well. The 182 mm half-cut PERC cells respond effectively to diffuse light common on overcast Central European days. A low temperature coefficient limits power loss during hot summers, while the robust aluminum frame withstands the snow loads and wind pressure typical in Poland throughout the 25-year power warranty period.
How much energy will a 10-panel Q-SUN Solar QNM182-HS-60 460W system produce per year?
Ten QNM182-HS-60 panels at 460 Wp each total 4.6 kWp. Under Polish irradiance conditions (approximately 950–1,050 kWh/kWp per year), such a system will generate an estimated 4,370–4,830 kWh annually — enough to cover the consumption of a typical Polish household. Actual yield depends on roof orientation, tilt angle, shading, and local irradiance data.
Are Q-SUN Solar QNM182-HS-60 panels bifacial or monofacial?
The QNM182-HS-60 series is monofacial — power is generated from the front side only. These modules do not feature bifacial technology, so they do not harvest additional energy from light reflected off the ground or rooftop surface. For standard pitched-roof residential installations, monofacial modules are fully adequate and the absence of a rear active layer has no negative impact on system economics.
