Power Output
The Aptos Solar DNA-108-BF10 415W delivers 415W per panel versus 400W for the Mission Solar MSE400, a 15W difference per module. To build an 8 kW residential system, you would need 20 Mission Solar MSE400 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 Aptos Solar DNA-108-BF10 415W has a temperature coefficient of -0.32%/°C versus -0.35%/°C for the Mission Solar MSE400. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Aptos Solar DNA-108-BF10 415W retains 93.6% 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 Mission Solar MSE400 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 (1% first year then 0.4%/year for Mission Solar MSE400; 1% first year then 0.54%/year for Aptos Solar DNA-108-BF10 415W), after 25 years the Mission Solar MSE400 should retain approximately 89.4% of original output versus 86.0% for the Aptos Solar DNA-108-BF10 415W. This 3.4 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Mission Solar MSE400 measures 1722×1134×30mm and weighs 21 kg, while the Aptos Solar DNA-108-BF10 415W measures 1722×1134×35mm at 22 kg. 1.95 m² of panel area for the Mission Solar MSE400 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.
