Specifications Breakdown
Module Efficiency
The Meyer Burger White 400W achieves 21.7% module efficiency compared to Panasonic EverVolt H 410W's 21.6%, meaning Meyer Burger White 400W converts 0.1 percentage points more sunlight into electricity per square meter. In practical terms, the Panasonic EverVolt H 410W produces 210.0 watts per square meter of panel area while the Meyer Burger White 400W produces 204.8 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 Panasonic EverVolt H 410W delivers 410W per panel versus 400W for the Meyer Burger White 400W, a 10W difference per module. To build an 8 kW residential system, you would need 20 Panasonic EverVolt H 410W panels or 20 Meyer Burger White 400W 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 -0.26%/°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 94.8% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The Panasonic EverVolt H 410W is backed by a 25-year product warranty and 25-year performance guarantee, while the Meyer Burger White 400W offers 25-year product and 30-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (0.5% first year then 0.35%/year for Panasonic EverVolt H 410W; 1% first year then 0.25%/year for Meyer Burger White 400W), after 25 years the Panasonic EverVolt H 410W should retain approximately 91.1% of original output versus 93.0% for the Meyer Burger White 400W. This 1.9 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Panasonic EverVolt H 410W measures 1722×1134×30mm and weighs 21.5 kg, while the Meyer Burger White 400W measures 1722×1134×35mm at 21 kg. 1.95 m² of panel area for the Panasonic EverVolt H 410W versus 1.95 m² for the Meyer Burger White 400W. 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.
