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.

5-Dimension Head-to-Head Analysis

1. Efficiency & Power Density

Winner: Meyer Burger White 400W

The Meyer Burger White 400W achieves 21.7% efficiency versus 21.6% — a 0.1 percentage point advantage. On a typical 30-panel residential roof, this translates to approximately 0.3 kW more total system capacity, or 2 kWh more annual production in an average US location.

2. Hot Climate Performance

Winner: Tie

Both panels share a temperature coefficient of -0.26%/°C — identical heat tolerance.

3. Durability & Warranty

Winner: Meyer Burger White 400W

Meyer Burger White 400W degrades more slowly at 0.25% per year versus 0.35%. After 25 years, expect 91.1% vs 93.0% of original output for Panasonic EverVolt H 410W and Meyer Burger White 400W respectively.

4. Power Output

Winner: Panasonic EverVolt H 410W

The Panasonic EverVolt H 410W delivers 410W versus 400W per panel — 10W more. For an 8 kW system, you need 20 panels with the higher-wattage option versus 20 panels, saving 0 panels and the associated racking and labor costs.

5. Cell Technology

Winner: Tie

The Panasonic EverVolt H 410W uses HJT (Heterojunction): HJT (Heterojunction) combines crystalline silicon with amorphous silicon layers, delivering the best temperature coefficient and bifacial gains, but at higher manufacturing cost.
