Power Output
Both panels are rated at 460W under standard test conditions (STC), requiring 18 panels each to build an 8 kW system. With identical wattage ratings, the power output dimension is a draw and does not favor either panel. The real differentiators become efficiency density, temperature behavior, and long-term degradation rates which determine actual field performance beyond the nameplate rating.
Temperature Coefficient
The Astronergy ASTRO N5 460W has a temperature coefficient of -0.34%/°C versus -0.35%/°C for the Aptos Solar DNA-120-BF10 460W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Astronergy ASTRO N5 460W retains 93.2% of its rated power while the other retains 93.0%. While the numerical gap is modest, it still accumulates over decades of summer production, especially in southern latitudes with prolonged peak heat hours.
Warranty Coverage
The Astronergy ASTRO N5 460W is backed by a 12-year product warranty and 25-year performance guarantee, while the Aptos Solar DNA-120-BF10 460W offers 30-year product and 30-year performance coverage. The Aptos Solar DNA-120-BF10 460W provides 18 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 0.54%/year for Aptos Solar DNA-120-BF10 460W), after 25 years the Astronergy ASTRO N5 460W should retain approximately 86.5% of original output versus 86.0% for the Aptos Solar DNA-120-BF10 460W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Astronergy ASTRO N5 460W measures 1762×1134×30mm and weighs 23 kg, while the Aptos Solar DNA-120-BF10 460W measures 1908×1134×35mm at 24.5 kg. 2.00 m² of panel area for the Astronergy ASTRO N5 460W versus 2.16 m² for the Aptos Solar DNA-120-BF10 460W. Their weights are closely matched, so neither panel imposes a significantly different structural load on the mounting system. The more compact Astronergy ASTRO N5 460W may be easier to fit on irregularly shaped or space-limited rooftops.
