Power Output
The Aptos Solar DNA-144-MF26 440W Silver delivers 440W per panel versus 400W for the Boviet Solar Vega 400W, a 40W difference per module. To build an 8 kW residential system, you would need 20 Boviet Solar Vega 400W panels or 19 Aptos Solar DNA-144-MF26 440W Silver 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
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 Boviet Solar Vega 400W is backed by a 12-year product warranty and 25-year performance guarantee, while the Aptos Solar DNA-144-MF26 440W Silver offers 25-year product and 30-year performance coverage. The Aptos Solar DNA-144-MF26 440W Silver provides 13 additional years of defect protection, covering manufacturing issues, material failures, and premature performance loss. Based on their published degradation rates (1.5% first year then 0.5%/year for Boviet Solar Vega 400W; 1% first year then 0.54%/year for Aptos Solar DNA-144-MF26 440W Silver), after 25 years the Boviet Solar Vega 400W should retain approximately 86.5% of original output versus 86.0% for the Aptos Solar DNA-144-MF26 440W Silver. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Boviet Solar Vega 400W measures 1722×1134×30mm and weighs 20.5 kg, while the Aptos Solar DNA-144-MF26 440W Silver measures 2095×1039×40mm at 24.1 kg. 1.95 m² of panel area for the Boviet Solar Vega 400W versus 2.18 m² for the Aptos Solar DNA-144-MF26 440W Silver. The Boviet Solar Vega 400W is 3.6 kg lighter per panel, which reduces structural load requirements on the roof and makes handling easier during installation. For a 20-panel system, that is a total weight difference of 72 kg. The more compact Boviet Solar Vega 400W may be easier to fit on irregularly shaped or space-limited rooftops.
