Specifications Breakdown
Module Efficiency
The Hanwha Q.TRON G11S 410W achieves 21.3% module efficiency compared to Q CELLS Q.PEAK DUO 370W's 20.4%, meaning Hanwha Q.TRON G11S 410W converts 0.9 percentage points more sunlight into electricity per square meter. In practical terms, the Q CELLS Q.PEAK DUO 370W produces 189.5 watts per square meter of panel area while the Hanwha Q.TRON G11S 410W produces 210.0 W/m². For rooftop installations where space is limited, this efficiency gap determines how many kilowatts you can fit on your available roof area. Over a 25-year system life, even a small efficiency advantage compounds into meaningful additional energy production.
Power Output
The Hanwha Q.TRON G11S 410W delivers 410W per panel versus 370W for the Q CELLS Q.PEAK DUO 370W, a 40W difference per module. To build an 8 kW residential system, you would need 22 Q CELLS Q.PEAK DUO 370W panels or 20 Hanwha Q.TRON G11S 410W panels. Choosing the higher-wattage option saves 2 panels, reducing total racking hardware, wiring, and installation labor costs. Higher wattage per panel is particularly valuable for commercial-scale installations where panel count directly impacts balance-of-system costs.
Temperature Coefficient
The Hanwha Q.TRON G11S 410W has a temperature coefficient of -0.29%/°C versus -0.35%/°C for the Q CELLS Q.PEAK DUO 370W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Hanwha Q.TRON G11S 410W retains 94.2% of its rated power while the other retains 93.0%. This difference is particularly significant in hot climates such as the American Southwest, the Middle East, and Southeast Asia, where panels routinely operate 30-40°C above STC for several hours each day. Over the system lifetime, the cumulative energy advantage from a better temperature coefficient can amount to 2-4% of total production.
Warranty Coverage
The Q CELLS Q.PEAK DUO 370W is backed by a 12-year product warranty and 25-year performance guarantee, while the Hanwha Q.TRON G11S 410W offers 25-year product and 25-year performance coverage.
