The Q.PEAK DUO ML-G11 Spec Sheet
Q CELLS' current flagship residential panel as of 2024-2026 is the Q.PEAK DUO ML-G11, available in 400, 405, 410, 415, and 420 watt variants. All variants use the same physical panel and cell design; the wattage difference is the binning at the factory (panels manufactured slightly above or below nameplate get sorted into the closest wattage bin).
Cell technology: PERC (passivated emitter rear contact) with half-cut cell architecture and multi-busbar interconnect. Q.ANTUM-branded multi-layer anti-reflection coating.
Efficiency: 20.7% (400W) to 21.4% (420W). Mainstream for tier-1 mono-PERC. Lower than REC HJT (22.6%) and Maxeon IBC (22.8%) but well above budget polycrystalline (15-17%) and thin-film (10-13%).
Temperature coefficient: -0.34%/°C. Standard for PERC technology. About 0.10%/°C worse than HJT panels, meaning Q CELLS lose roughly 1.5% more production in hot summer conditions than equivalent REC panels.
Dimensions: 1722 × 1134 × 32mm. Industry-standard residential panel size, fits all major racking systems (IronRidge, Unirac, SnapNrack, Quick Mount). Weight 21.2 kg.
Performance warranty: 25-year linear power warranty starting at 98% in year 1, declining 0.54%/year, ending at 85% in year 25. Product warranty (workmanship): 12 years.
Why Q CELLS Dominates US Residential Volume
Q CELLS overtook every other brand in US residential panel sales volume in 2020 and has held the lead since. The drivers:
Price/performance balance: Best mainstream value, well-known brand, US assembly, decent warranty. The "no one ever got fired for choosing Q CELLS" pick.
Installer relationships: Q CELLS has deep distribution relationships with mass-market residential installers (Sunrun, Sunnova, Trinity Solar, Momentum Solar, ADT Solar). These installers pre-stock Q CELLS and quote them as default; getting REC or Maxeon often requires the customer to ask explicitly.
Q.ANTUM marketing: The Q.ANTUM branding and the related Q.HOME ENERGY brand have built consumer recognition through trade-show presence, installer-channel marketing, and continual product refresh.
Frequently Asked Questions
How much do Q CELLS solar panels cost installed?
Installed cost ranges $2.65 to $3.10 per watt in 2026 depending on panel sub-model and installer. A 6kW system with Q CELLS Q.PEAK DUO ML-G11 410W panels typically runs $15,900 to $18,600 gross. Q CELLS sits at the mainstream-value tier of the US residential panel market: higher than budget brands (Canadian Solar, JA Solar) but well below premium (REC, SunPower Maxeon).
Who makes Q CELLS panels?
Hanwha Q CELLS, a South Korean manufacturer owned by Hanwha Group (chaebol with chemical, defense, and finance segments). Headquartered in Seoul. Manufactures panels in South Korea, Malaysia, and the US (Cartersville, Georgia, plus the new Dalton, Georgia facility that opened in 2024 making solar wafers, cells, and modules for full US vertical integration). Q CELLS has been the top-selling residential solar panel brand in the US by volume since 2020 per Wood Mackenzie tracking.
What is the Q.PEAK DUO ML-G11?
Q CELLS' current flagship residential panel. ML-G11 designates the 11th-generation panel design with M10 wafer size (182mm cells). Available in 400W, 405W, 410W, 415W, and 420W variants. Uses Q.ANTUM DUO Z technology, which is half-cut PERC cells with wire-busbar interconnect. Efficiency: 20.7 to 21.4% depending on wattage. Solid mainstream choice with a 25-year power warranty and 12-year product warranty.
Are Q CELLS made in the USA?
Many models are assembled in Cartersville, Georgia from US-made cells and components. The new Dalton, Georgia facility (opened 2024) brings polysilicon-to-module manufacturing into the US for full vertical integration.
Q CELLS vs REC vs Canadian Solar comparison?
Canadian Solar HiKu6 415W: $2.40 to $2.80/W installed, 21.2% efficiency, 12-year product / 25-year power warranty. Q CELLS Q.PEAK DUO ML-G11 410W: $2.65 to $3.10/W, 21.4% efficiency, same warranty. REC Alpha Pure R 430W: $3.10 to $3.55/W, 22.6% efficiency, 25-year product / 25-year power warranty. For most homeowners with adequate roof space, Q CELLS is the best price/performance/brand-recognition balance.
What's the warranty on Q CELLS panels?
12-year product warranty (workmanship and materials) and 25-year linear power warranty (98% in year 1, declining 0.54%/year, finishing at 85% in year 25). The Q.PEAK DUO BLK ML-G10+ models that qualify for Q.ANTUM Technology have a slightly stronger 25-year/85% power warranty curve. Mainstream for the industry but shorter on product coverage than premium brands like REC (25-year product) or Maxeon (40-year).
What's the Q.ANTUM Technology marketing claim?
Q.ANTUM is Q CELLS' branding for their multi-layer anti-reflection cell coating that improves light absorption, plus their proprietary anti-PID (potential induced degradation) treatment. The combination delivers slightly better real-world performance than vanilla PERC cells, especially in low-light conditions. Marketing-heavy term, but the underlying tech is genuine and the panel performance is consistent with the claims in independent testing (e.g., DNV-GL PV Module Reliability Scorecard, which Q CELLS has appeared in the top tier of for the past 5 years).
