Specifications Breakdown
Module Efficiency
The Panasonic EverVolt 410 achieves 21.5% module efficiency compared to Aptos Solar DNA-120-BF10 460W's 21.26%, meaning Panasonic EverVolt 410 converts 0.2 percentage points more sunlight into electricity per square meter. In practical terms, the Panasonic EverVolt 410 produces 210.0 watts per square meter of panel area while the Aptos Solar DNA-120-BF10 460W produces 212.6 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 Aptos Solar DNA-120-BF10 460W delivers 460W per panel versus 410W for the Panasonic EverVolt 410, a 50W difference per module. To build an 8 kW residential system, you would need 20 Panasonic EverVolt 410 panels or 18 Aptos Solar DNA-120-BF10 460W 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 Panasonic EverVolt 410 has a temperature coefficient of -0.26%/°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 Panasonic EverVolt 410 retains 94.8% of its rated power while the other retains 93.0%. 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 Panasonic EverVolt 410 is backed by a 25-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 5 additional years of defect protection, covering manufacturing issues, material failures, and premature performance loss. Based on their published degradation rates (0.5% first year then 0.35%/year for Panasonic EverVolt 410; 1% first year then 0.54%/year for Aptos Solar DNA-120-BF10 460W), after 25 years the Panasonic EverVolt 410 should retain approximately 91.1% of original output versus 86.0% for the Aptos Solar DNA-120-BF10 460W. This 5.1 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Panasonic EverVolt 410 measures 1722×1134×30mm and weighs 21.5 kg, while the Aptos Solar DNA-120-BF10 460W measures 1908×1134×35mm at 24.5 kg. 1.95 m² of panel area for the Panasonic EverVolt 410 versus 2.16 m² for the Aptos Solar DNA-120-BF10 460W. The Panasonic EverVolt 410 is 3.0 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 60 kg. The more compact Panasonic EverVolt 410 may be easier to fit on irregularly shaped or space-limited rooftops.
