Specifications Breakdown

Module Efficiency

The Panasonic EverVolt 410 achieves 21.5% module efficiency compared to Aptos Solar DNA-108-BF10 415W's 21.25%, meaning Panasonic EverVolt 410 converts 0.3 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-108-BF10 415W produces 212.5 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-108-BF10 415W delivers 415W per panel versus 410W for the Panasonic EverVolt 410, a 5W difference per module. To build an 8 kW residential system, you would need 20 Panasonic EverVolt 410 panels or 20 Aptos Solar DNA-108-BF10 415W panels. Despite the per-panel wattage difference, both require the same number of panels for this system size due to rounding. 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 -0.32%/°C for the Aptos Solar DNA-108-BF10 415W. 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 93.6%. 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-108-BF10 415W offers 30-year product and 30-year performance coverage. The Aptos Solar DNA-108-BF10 415W 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-108-BF10 415W), after 25 years the Panasonic EverVolt 410 should retain approximately 91.1% of original output versus 86.0% for the Aptos Solar DNA-108-BF10 415W. 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-108-BF10 415W measures 1722×1134×35mm at 22 kg. 1.95 m² of panel area for the Panasonic EverVolt 410 versus 1.95 m² for the Aptos Solar DNA-108-BF10 415W. 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.
