Specifications Breakdown
Module Efficiency
Both the LONGi Hi-MO X6 445W and Boviet Solar Vega 460W share identical 22% module efficiency, producing comparable power per unit area. The LONGi Hi-MO X6 445W generates 227.9 W/m² while the Boviet Solar Vega 460W generates 230.2 W/m² based on their respective panel dimensions. With matched efficiency, neither panel holds a density advantage for space-constrained rooftop installations, so other factors like warranty coverage and temperature performance become the deciding metrics.
Power Output
The Boviet Solar Vega 460W delivers 460W per panel versus 445W for the LONGi Hi-MO X6 445W, a 15W difference per module. To build an 8 kW residential system, you would need 18 LONGi Hi-MO X6 445W 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
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 LONGi Hi-MO X6 445W 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% first year then 0.4%/year for LONGi Hi-MO X6 445W; 1% first year then 0.4%/year for Boviet Solar Vega 460W), after 25 years the LONGi Hi-MO X6 445W 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 LONGi Hi-MO X6 445W 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 LONGi Hi-MO X6 445W versus 2.00 m² for the Boviet Solar Vega 460W. The LONGi Hi-MO X6 445W 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.
