Specifications Breakdown
Module Efficiency
The Boviet Solar Vega 460W achieves 22% module efficiency compared to Seraphim S4 Series 430W's 21.2%, meaning Boviet Solar Vega 460W converts 0.8 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 Seraphim S4 Series 430W produces 220.2 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 430W for the Seraphim S4 Series 430W, a 30W difference per module. To build an 8 kW residential system, you would need 18 Boviet Solar Vega 460W panels or 19 Seraphim S4 Series 430W 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
The Boviet Solar Vega 460W has a temperature coefficient of -0.29%/°C versus -0.34%/°C for the Seraphim S4 Series 430W. 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 93.2%. 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 Seraphim S4 Series 430W offers 12-year product and 25-year performance coverage. The Boviet Solar Vega 460W provides 3 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; 1.5% first year then 0.5%/year for Seraphim S4 Series 430W), after 25 years the Boviet Solar Vega 460W should retain approximately 89.4% of original output versus 86.5% for the Seraphim S4 Series 430W. This 2.9 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 Seraphim S4 Series 430W measures 1722×1134×30mm at 21 kg. 2.00 m² of panel area for the Boviet Solar Vega 460W versus 1.95 m² for the Seraphim S4 Series 430W. The Seraphim S4 Series 430W is 2.5 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 50 kg. Similar footprints mean both panels fit comparably on standard residential rooftop configurations.
