Specifications Breakdown
Module Efficiency
The Tongwei THN-PE14M10 450W achieves 21.5% module efficiency compared to Hanwha Q.TRON G11S 410W's 21.3%, meaning Tongwei THN-PE14M10 450W converts 0.2 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 Tongwei THN-PE14M10 450W produces 225.2 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 Tongwei THN-PE14M10 450W delivers 450W per panel versus 410W for the Hanwha Q.TRON G11S 410W, a 40W difference per module. To build an 8 kW residential system, you would need 20 Hanwha Q.TRON G11S 410W panels or 18 Tongwei THN-PE14M10 450W 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 -0.34%/°C for the Tongwei THN-PE14M10 450W. 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 93.2%. 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 Tongwei THN-PE14M10 450W offers 12-year product and 25-year performance coverage. The Hanwha Q.TRON G11S 410W provides 13 additional years of defect protection, covering manufacturing issues, material failures, and premature performance loss. Based on their published degradation rates (1% first year then 0.4%/year for Hanwha Q.TRON G11S 410W; 1.5% first year then 0.5%/year for Tongwei THN-PE14M10 450W), after 25 years the Hanwha Q.TRON G11S 410W should retain approximately 89.4% of original output versus 86.5% for the Tongwei THN-PE14M10 450W. This 2.9 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 Tongwei THN-PE14M10 450W measures 1762×1134×30mm at 23 kg. 1.95 m² of panel area for the Hanwha Q.TRON G11S 410W versus 2.00 m² for the Tongwei THN-PE14M10 450W. The Hanwha Q.TRON G11S 410W is 2.2 kg lighter per panel, which reduces structural load requirements on the roof and makes handling easier during installation. For a 20-panel system, that is a total weight difference of 44 kg. Similar footprints mean both panels fit comparably on standard residential rooftop configurations.
