Specifications Breakdown
Module Efficiency
The Hanwha Q.TRON G11S 410W achieves 21.3% module efficiency compared to Mission Solar MSE400's 20.6%, meaning Hanwha Q.TRON G11S 410W converts 0.7 percentage points more sunlight into electricity per square meter. In practical terms, the Mission Solar MSE400 produces 204.8 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 400W for the Mission Solar MSE400, a 10W difference per module. To build an 8 kW residential system, you would need 20 Mission Solar MSE400 panels or 20 Hanwha Q.TRON G11S 410W panels. Despite the per-panel wattage difference, both require the same number of panels for this system size due to rounding. 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 Mission Solar MSE400. 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 Mission Solar MSE400 is backed by a 25-year product warranty and 25-year performance guarantee, while the Hanwha Q.TRON G11S 410W offers 25-year product and 25-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1% first year then 0.4%/year for Mission Solar MSE400; 1% first year then 0.4%/year for Hanwha Q.TRON G11S 410W), after 25 years the Mission Solar MSE400 should retain approximately 89.4% of original output versus 89.4% for the Hanwha Q.TRON G11S 410W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Mission Solar MSE400 measures 1722×1134×30mm and weighs 21 kg, while the Hanwha Q.TRON G11S 410W measures 1722×1134×30mm at 20.8 kg. 1.95 m² of panel area for the Mission Solar MSE400 versus 1.95 m² for the Hanwha Q.TRON G11S 410W. Their weights are closely matched, so neither panel imposes a significantly different structural load on the mounting system. Similar footprints mean both panels fit comparably on standard residential rooftop configurations.
