Specifications Breakdown
Module Efficiency
The Boviet Solar Vega 460W achieves 22% module efficiency compared to Aptos Solar DNA-120-BF10 460W's 21.26%, meaning Boviet Solar Vega 460W converts 0.7 percentage points more sunlight into electricity per square meter. In practical terms, the Boviet Solar Vega 460W produces 230.2 watts per square meter of panel area while the Aptos Solar DNA-120-BF10 460W produces 212.6 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
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
The Boviet Solar Vega 460W has a temperature coefficient of -0.29%/°C versus -0.35%/°C for the Aptos Solar DNA-120-BF10 460W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Boviet Solar Vega 460W retains 94.2% of its rated power while the other retains 93.0%. 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 Boviet Solar Vega 460W is backed by a 15-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. The Aptos Solar DNA-120-BF10 460W provides 15 additional years of defect protection, covering manufacturing issues, material failures, and premature performance loss. Based on their published degradation rates (1% first year then 0.4%/year for Boviet Solar Vega 460W; 1% first year then 0.54%/year for Aptos Solar DNA-120-BF10 460W), after 25 years the Boviet Solar Vega 460W should retain approximately 89.4% of original output versus 86.0% for the Aptos Solar DNA-120-BF10 460W. This 3.4 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Boviet Solar Vega 460W measures 1762×1134×30mm and weighs 23.5 kg, while the Aptos Solar DNA-120-BF10 460W measures 1908×1134×35mm at 24.5 kg. 2.00 m² of panel area for the Boviet Solar Vega 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. The more compact Boviet Solar Vega 460W may be easier to fit on irregularly shaped or space-limited rooftops.
