Specifications Breakdown
Module Efficiency
The Meyer Burger White 400W achieves 21.7% module efficiency compared to Aptos Solar DNA-108-MF10 415W's 21.25%, meaning Meyer Burger White 400W converts 0.4 percentage points more sunlight into electricity per square meter. In practical terms, the Aptos Solar DNA-108-MF10 415W produces 212.5 watts per square meter of panel area while the Meyer Burger White 400W produces 204.8 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-MF10 415W delivers 415W per panel versus 400W for the Meyer Burger White 400W, a 15W difference per module. To build an 8 kW residential system, you would need 20 Aptos Solar DNA-108-MF10 415W panels or 20 Meyer Burger White 400W 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 Meyer Burger White 400W has a temperature coefficient of -0.26%/°C versus -0.32%/°C for the Aptos Solar DNA-108-MF10 415W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Meyer Burger White 400W 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 Aptos Solar DNA-108-MF10 415W is backed by a 30-year product warranty and 30-year performance guarantee, while the Meyer Burger White 400W offers 25-year product and 30-year performance coverage. The Aptos Solar DNA-108-MF10 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 0.54%/year for Aptos Solar DNA-108-MF10 415W; 1% first year then 0.25%/year for Meyer Burger White 400W), after 25 years the Aptos Solar DNA-108-MF10 415W should retain approximately 86.0% of original output versus 93.0% for the Meyer Burger White 400W. This 7.0 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Aptos Solar DNA-108-MF10 415W measures 1722×1134×35mm and weighs 21.5 kg, while the Meyer Burger White 400W measures 1722×1134×35mm at 21 kg. 1.95 m² of panel area for the Aptos Solar DNA-108-MF10 415W versus 1.95 m² for the Meyer Burger White 400W.
