In practical terms, the Aptos Solar DNA-108-MF10 415W produces 212.5 watts per square meter of panel area while the Meyer Burger Glass 390W produces 199.7 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 390W for the Meyer Burger Glass 390W, a 25W difference per module. To build an 8 kW residential system, you would need 20 Aptos Solar DNA-108-MF10 415W panels or 21 Meyer Burger Glass 390W panels. Choosing the higher-wattage option saves 1 panel, 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 Meyer Burger Glass 390W 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 Glass 390W 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 Glass 390W offers 25-year product and 30-year performance coverage.
