Specifications Breakdown
Module Efficiency
The Aptos Solar DNA-120-MF10 460W achieves 21.26% module efficiency compared to CertainTeed Solstice Solar Shingle's 15.4%, meaning Aptos Solar DNA-120-MF10 460W converts 5.9 percentage points more sunlight into electricity per square meter. In practical terms, the Aptos Solar DNA-120-MF10 460W produces 212.6 watts per square meter of panel area while the CertainTeed Solstice Solar Shingle produces 101.8 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-120-MF10 460W delivers 460W per panel versus 70W for the CertainTeed Solstice Solar Shingle, a 390W difference per module. To build an 8 kW residential system, you would need 18 Aptos Solar DNA-120-MF10 460W panels or 115 CertainTeed Solstice Solar Shingle panels. Choosing the higher-wattage option saves 97 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 Aptos Solar DNA-120-MF10 460W has a temperature coefficient of -0.35%/°C versus -0.4%/°C for the CertainTeed Solstice Solar Shingle. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Aptos Solar DNA-120-MF10 460W retains 93.0% of its rated power while the other retains 92.0%. 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 Aptos Solar DNA-120-MF10 460W is backed by a 30-year product warranty and 30-year performance guarantee, while the CertainTeed Solstice Solar Shingle offers 15-year product and 25-year performance coverage.
