Specifications Breakdown
Module Efficiency
Both the Aptos Solar DNA-120-MF10 460W and Aptos Solar DNA-120-BF10 460W share identical 21.26% module efficiency, producing comparable power per unit area. The Aptos Solar DNA-120-MF10 460W generates 212.6 W/m² while the Aptos Solar DNA-120-BF10 460W generates 212.6 W/m² based on their respective panel dimensions. With matched efficiency, neither panel holds a density advantage for space-constrained rooftop installations, so other factors like warranty coverage and temperature performance become the deciding metrics.
Power Output
Both panels are rated at 460W under standard test conditions (STC), requiring 18 panels each to build an 8 kW system. With identical wattage ratings, the power output dimension is a draw and does not favor either panel. The real differentiators become efficiency density, temperature behavior, and long-term degradation rates which determine actual field performance beyond the nameplate rating.
Temperature Coefficient
Both panels share an identical temperature coefficient of -0.35%/°C, meaning they lose power at the same rate as cell temperature rises above the 25°C standard test baseline. At 65°C cell temperature, both retain 93.0% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The Aptos Solar DNA-120-MF10 460W is backed by a 30-year product warranty and 30-year performance guarantee, while the Aptos Solar DNA-120-BF10 460W offers 30-year product and 30-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1% first year then 0.54%/year for Aptos Solar DNA-120-MF10 460W; 1% first year then 0.54%/year for Aptos Solar DNA-120-BF10 460W), after 25 years the Aptos Solar DNA-120-MF10 460W should retain approximately 86.0% of original output versus 86.0% for the Aptos Solar DNA-120-BF10 460W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Aptos Solar DNA-120-MF10 460W measures 1908×1134×35mm and weighs 24 kg, while the Aptos Solar DNA-120-BF10 460W measures 1908×1134×35mm at 24.5 kg. 2.16 m² of panel area for the Aptos Solar DNA-120-MF10 460W versus 2.16 m² for the Aptos Solar DNA-120-BF10 460W. 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.
