Specifications Breakdown
Module Efficiency
The Astronergy ASTRO N7 580W achieves 22.4% module efficiency compared to Hanwha Q.TRON G11S 410W's 21.3%, meaning Astronergy ASTRO N7 580W converts 1.1 percentage points more sunlight into electricity per square meter. In practical terms, the Astronergy ASTRO N7 580W produces 224.5 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 Astronergy ASTRO N7 580W delivers 580W per panel versus 410W for the Hanwha Q.TRON G11S 410W, a 170W difference per module. To build an 8 kW residential system, you would need 14 Astronergy ASTRO N7 580W panels or 20 Hanwha Q.TRON G11S 410W panels. Choosing the higher-wattage option saves 6 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
Both panels share an identical temperature coefficient of -0.29%/°C, meaning they lose power at the same rate as cell temperature rises above the 25°C standard test baseline. At 65°C cell temperature, both retain 94.2% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The Astronergy ASTRO N7 580W is backed by a 15-year product warranty and 30-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 10 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 Astronergy ASTRO N7 580W; 1% first year then 0.4%/year for Hanwha Q.TRON G11S 410W), after 25 years the Astronergy ASTRO N7 580W 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 Astronergy ASTRO N7 580W measures 2278×1134×35mm and weighs 28.5 kg, while the Hanwha Q.TRON G11S 410W measures 1722×1134×30mm at 20.8 kg. 2.58 m² of panel area for the Astronergy ASTRO N7 580W versus 1.95 m² for the Hanwha Q.TRON G11S 410W. The Hanwha Q.TRON G11S 410W is 7.7 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 154 kg. The more compact Hanwha Q.TRON G11S 410W may be easier to fit on irregularly shaped or space-limited rooftops.
