Specifications Breakdown
Module Efficiency
Both the Astronergy ASTRO N5 460W and Hanwha Q.TRON G11S 410W share identical 21.3% module efficiency, producing comparable power per unit area. The Astronergy ASTRO N5 460W generates 230.2 W/m² while the Hanwha Q.TRON G11S 410W generates 210.0 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 Astronergy ASTRO N5 460W delivers 460W per panel versus 410W for the Hanwha Q.TRON G11S 410W, a 50W difference per module. To build an 8 kW residential system, you would need 18 Astronergy ASTRO N5 460W panels or 20 Hanwha Q.TRON G11S 410W 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 Astronergy ASTRO N5 460W. 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 Astronergy ASTRO N5 460W is backed by a 12-year product warranty and 25-year performance guarantee, while the Hanwha Q.TRON G11S 410W offers 25-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 (1.5% first year then 0.5%/year for Astronergy ASTRO N5 460W; 1% first year then 0.4%/year for Hanwha Q.TRON G11S 410W), after 25 years the Astronergy ASTRO N5 460W should retain approximately 86.5% of original output versus 89.4% for the Hanwha Q.TRON G11S 410W. This 2.9 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Astronergy ASTRO N5 460W measures 1762×1134×30mm and weighs 23 kg, while the Hanwha Q.TRON G11S 410W measures 1722×1134×30mm at 20.8 kg. 2.00 m² of panel area for the Astronergy ASTRO N5 460W versus 1.95 m² for the Hanwha Q.TRON G11S 410W. 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.
