Specifications Breakdown
Module Efficiency
Both the Hanwha Q.TRON G11S 410W and Solaria PowerXT 430R share identical 21.3% module efficiency, producing comparable power per unit area. The Hanwha Q.TRON G11S 410W generates 210.0 W/m² while the Solaria PowerXT 430R generates 212.9 W/m² based on their respective panel dimensions. With matched efficiency, neither panel holds a density advantage for space-constrained rooftop installations, so other factors like warranty coverage and temperature performance become the deciding metrics.
Power Output
The Solaria PowerXT 430R delivers 430W per panel versus 410W for the Hanwha Q.TRON G11S 410W, a 20W difference per module. To build an 8 kW residential system, you would need 20 Hanwha Q.TRON G11S 410W panels or 19 Solaria PowerXT 430R 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 -0.34%/°C for the Solaria PowerXT 430R. 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 Solaria PowerXT 430R 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 Hanwha Q.TRON G11S 410W; 1.5% first year then 0.4%/year for Solaria PowerXT 430R), after 25 years the Hanwha Q.TRON G11S 410W should retain approximately 89.4% of original output versus 88.9% for the Solaria PowerXT 430R. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Hanwha Q.TRON G11S 410W measures 1722×1134×30mm and weighs 20.8 kg, while the Solaria PowerXT 430R measures 1879×1075×40mm at 22 kg. 1.95 m² of panel area for the Hanwha Q.TRON G11S 410W versus 2.02 m² for the Solaria PowerXT 430R. 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.
