Specifications Breakdown
Module Efficiency
The Boviet Solar Vega 460W achieves 22% module efficiency compared to Waaree WS-440's 21.8%, meaning Boviet Solar Vega 460W converts 0.2 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 Waaree WS-440 produces 225.3 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 440W for the Waaree WS-440, a 20W difference per module. To build an 8 kW residential system, you would need 18 Boviet Solar Vega 460W panels or 19 Waaree WS-440 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 -0.3%/°C for the Waaree WS-440. 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 94.0%. While the numerical gap is modest, it still accumulates over decades of summer production, especially in southern latitudes with prolonged peak heat hours.
Warranty Coverage
The Boviet Solar Vega 460W is backed by a 15-year product warranty and 30-year performance guarantee, while the Waaree WS-440 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% first year then 0.4%/year for Waaree WS-440), after 25 years the Boviet Solar Vega 460W should retain approximately 89.4% of original output versus 89.4% for the Waaree WS-440. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Boviet Solar Vega 460W measures 1762×1134×30mm and weighs 23.5 kg, while the Waaree WS-440 measures 1722×1134×30mm at 21.5 kg. 2.00 m² of panel area for the Boviet Solar Vega 460W versus 1.95 m² for the Waaree WS-440. The Waaree WS-440 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.
