Specifications Breakdown
Module Efficiency
The Hanwha Q.TRON G11S 410W achieves 21.3% module efficiency compared to Aptos Solar DNA-144-MF26 440W Silver's 20.21%, meaning Hanwha Q.TRON G11S 410W converts 1.1 percentage points more sunlight into electricity per square meter. In practical terms, the Hanwha Q.TRON G11S 410W produces 210.0 watts per square meter of panel area while the Aptos Solar DNA-144-MF26 440W Silver produces 202.1 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 Aptos Solar DNA-144-MF26 440W Silver delivers 440W per panel versus 410W for the Hanwha Q.TRON G11S 410W, a 30W difference per module. To build an 8 kW residential system, you would need 20 Hanwha Q.TRON G11S 410W panels or 19 Aptos Solar DNA-144-MF26 440W Silver panels. Choosing the higher-wattage option saves 1 panel, 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 Aptos Solar DNA-144-MF26 440W Silver. 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 Hanwha Q.TRON G11S 410W is backed by a 25-year product warranty and 25-year performance guarantee, while the Aptos Solar DNA-144-MF26 440W Silver offers 25-year product and 30-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1% first year then 0.4%/year for Hanwha Q.TRON G11S 410W; 1% first year then 0.54%/year for Aptos Solar DNA-144-MF26 440W Silver), after 25 years the Hanwha Q.TRON G11S 410W should retain approximately 89.4% of original output versus 86.0% for the Aptos Solar DNA-144-MF26 440W Silver. This 3.4 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Hanwha Q.TRON G11S 410W measures 1722×1134×30mm and weighs 20.8 kg, while the Aptos Solar DNA-144-MF26 440W Silver measures 2095×1039×40mm at 24.1 kg. 1.95 m² of panel area for the Hanwha Q.TRON G11S 410W versus 2.18 m² for the Aptos Solar DNA-144-MF26 440W Silver.
