Specifications Breakdown
Module Efficiency
The Boviet Solar Vega 460W achieves 22% module efficiency compared to Canadian Solar HiKu6 455W's 21.4%, meaning Boviet Solar Vega 460W converts 0.6 percentage points more sunlight into electricity per square meter. In practical terms, the Canadian Solar HiKu6 455W produces 227.7 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 455W for the Canadian Solar HiKu6 455W, a 5W difference per module. To build an 8 kW residential system, you would need 18 Canadian Solar HiKu6 455W panels or 18 Boviet Solar Vega 460W panels. Despite the per-panel wattage difference, both require the same number of panels for this system size due to rounding. 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 Canadian Solar HiKu6 455W. 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 Canadian Solar HiKu6 455W is backed by a 12-year product warranty and 25-year performance guarantee, while the Boviet Solar Vega 460W offers 15-year product and 30-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 (1.5% first year then 0.5%/year for Canadian Solar HiKu6 455W; 1% first year then 0.4%/year for Boviet Solar Vega 460W), after 25 years the Canadian Solar HiKu6 455W should retain approximately 86.5% of original output versus 89.4% for the Boviet Solar Vega 460W. This 2.9 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Canadian Solar HiKu6 455W measures 1762×1134×30mm and weighs 23 kg, while the Boviet Solar Vega 460W measures 1762×1134×30mm at 23.5 kg. 2.00 m² of panel area for the Canadian Solar HiKu6 455W versus 2.00 m² for the Boviet Solar Vega 460W. 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.
