Specifications Breakdown
Module Efficiency
The Hanwha Q.TRON G11S 410W achieves 21.3% module efficiency compared to ZNShine Solar ZXM6-SHLD108 420W's 21%, meaning Hanwha Q.TRON G11S 410W converts 0.3 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 ZNShine Solar ZXM6-SHLD108 420W produces 215.1 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 ZNShine Solar ZXM6-SHLD108 420W delivers 420W per panel versus 410W for the Hanwha Q.TRON G11S 410W, a 10W difference per module. To build an 8 kW residential system, you would need 20 Hanwha Q.TRON G11S 410W panels or 20 ZNShine Solar ZXM6-SHLD108 420W 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 -0.34%/°C for the ZNShine Solar ZXM6-SHLD108 420W. 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 ZNShine Solar ZXM6-SHLD108 420W 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 ZNShine Solar ZXM6-SHLD108 420W), after 25 years the Hanwha Q.TRON G11S 410W should retain approximately 89.4% of original output versus 86.5% for the ZNShine Solar ZXM6-SHLD108 420W. 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 ZNShine Solar ZXM6-SHLD108 420W measures 1722×1134×30mm at 21 kg. 1.95 m² of panel area for the Hanwha Q.TRON G11S 410W versus 1.95 m² for the ZNShine Solar ZXM6-SHLD108 420W. 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.
