Specifications Breakdown

Module Efficiency

Both the Aptos Solar DNA-108-MF10 415W and Aptos Solar DNA-108-BF10 415W share identical 21.25% module efficiency, producing comparable power per unit area. The Aptos Solar DNA-108-MF10 415W generates 212.5 W/m² while the Aptos Solar DNA-108-BF10 415W generates 212.5 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 415W under standard test conditions (STC), requiring 20 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 -0.32%/°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 93.6% 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-108-MF10 415W is backed by a 30-year product warranty and 30-year performance guarantee, while the Aptos Solar DNA-108-BF10 415W 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-108-MF10 415W; 1% first year then 0.54%/year for Aptos Solar DNA-108-BF10 415W), after 25 years the Aptos Solar DNA-108-MF10 415W should retain approximately 86.0% of original output versus 86.0% for the Aptos Solar DNA-108-BF10 415W. The end-of-life output levels are closely matched.

Physical Dimensions & Weight

The Aptos Solar DNA-108-MF10 415W measures 1722×1134×35mm and weighs 21.5 kg, while the Aptos Solar DNA-108-BF10 415W measures 1722×1134×35mm at 22 kg. 1.95 m² of panel area for the Aptos Solar DNA-108-MF10 415W 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. Similar footprints mean both panels fit comparably on standard residential rooftop configurations.
