Specifications Breakdown
Module Efficiency
The Boviet Solar Vega 460W achieves 22% module efficiency compared to Q CELLS Q.TRON 425W's 21.8%, meaning Boviet Solar Vega 460W converts 0.2 percentage points more sunlight into electricity per square meter. In practical terms, the Q CELLS Q.TRON 425W produces 217.6 watts per square meter of panel area while the Boviet Solar Vega 460W produces 230.2 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 Boviet Solar Vega 460W delivers 460W per panel versus 425W for the Q CELLS Q.TRON 425W, a 35W difference per module. To build an 8 kW residential system, you would need 19 Q CELLS Q.TRON 425W panels or 18 Boviet Solar Vega 460W 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 -0.29%/°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 94.2% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The Q CELLS Q.TRON 425W is backed by a 25-year product warranty and 25-year performance guarantee, while the Boviet Solar Vega 460W offers 15-year product and 30-year performance coverage. The Q CELLS Q.TRON 425W provides 10 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 Q CELLS Q.TRON 425W; 1% first year then 0.4%/year for Boviet Solar Vega 460W), after 25 years the Q CELLS Q.TRON 425W should retain approximately 89.4% of original output versus 89.4% for the Boviet Solar Vega 460W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Q CELLS Q.TRON 425W measures 1722×1134×30mm and weighs 21.5 kg, while the Boviet Solar Vega 460W measures 1762×1134×30mm at 23.5 kg. 1.95 m² of panel area for the Q CELLS Q.TRON 425W versus 2.00 m² for the Boviet Solar Vega 460W. The Q CELLS Q.TRON 425W is 2.0 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 40 kg. Similar footprints mean both panels fit comparably on standard residential rooftop configurations.
