Specifications Breakdown
Module Efficiency
The Astronergy ASTRO N5 460W achieves 21.3% module efficiency compared to Trina Solar DE09R 430W's 21%, meaning Astronergy ASTRO N5 460W converts 0.3 percentage points more sunlight into electricity per square meter. In practical terms, the Trina Solar DE09R 430W produces 220.2 watts per square meter of panel area while the Astronergy ASTRO N5 460W produces 230.2 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 N5 460W delivers 460W per panel versus 430W for the Trina Solar DE09R 430W, a 30W difference per module. To build an 8 kW residential system, you would need 19 Trina Solar DE09R 430W panels or 18 Astronergy ASTRO N5 460W 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
Both panels share an identical temperature coefficient of -0.34%/°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 93.2% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The Trina Solar DE09R 430W is backed by a 12-year product warranty and 25-year performance guarantee, while the Astronergy ASTRO N5 460W offers 12-year product and 25-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1.5% first year then 0.5%/year for Trina Solar DE09R 430W; 1.5% first year then 0.5%/year for Astronergy ASTRO N5 460W), after 25 years the Trina Solar DE09R 430W should retain approximately 86.5% of original output versus 86.5% for the Astronergy ASTRO N5 460W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Trina Solar DE09R 430W measures 1722×1134×30mm and weighs 21.5 kg, while the Astronergy ASTRO N5 460W measures 1762×1134×30mm at 23 kg. 1.95 m² of panel area for the Trina Solar DE09R 430W versus 2.00 m² for the Astronergy ASTRO N5 460W. 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.
