Specifications Breakdown

Module Efficiency

Both the Panasonic EVPV400H and Meyer Burger Glass 390W share identical 21.2% module efficiency, producing comparable power per unit area. The Panasonic EVPV400H generates 204.8 W/m² while the Meyer Burger Glass 390W generates 199.7 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 Panasonic EVPV400H delivers 400W per panel versus 390W for the Meyer Burger Glass 390W, a 10W difference per module. To build an 8 kW residential system, you would need 20 Panasonic EVPV400H panels or 21 Meyer Burger Glass 390W 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

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 EVPV400H is backed by a 25-year product warranty and 25-year performance guarantee, while the Meyer Burger Glass 390W 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 EVPV400H; 1% first year then 0.25%/year for Meyer Burger Glass 390W), after 25 years the Panasonic EVPV400H should retain approximately 91.1% of original output versus 93.0% for the Meyer Burger Glass 390W. This 1.9 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.

Physical Dimensions & Weight

The Panasonic EVPV400H measures 1722×1134×30mm and weighs 21 kg, while the Meyer Burger Glass 390W measures 1722×1134×35mm at 22.5 kg. 1.95 m² of panel area for the Panasonic EVPV400H versus 1.95 m² for the Meyer Burger Glass 390W. 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: Tie

Both panels achieve 21.2% module efficiency, producing identical power per square meter. Neither has an advantage in space-constrained installations.

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 Glass 390W

Meyer Burger Glass 390W 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 EVPV400H and Meyer Burger Glass 390W respectively.

4. Power Output

Winner: Panasonic EVPV400H

The Panasonic EVPV400H delivers 400W versus 390W per panel — 10W more. For an 8 kW system, you need 20 panels with the higher-wattage option versus 21 panels, saving 1 panels and the associated racking and labor costs.

5. Cell Technology

Winner: Tie

The Panasonic EVPV400H 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. The Meyer Burger Glass 390W uses HJT (Heterojunction) N-type: HJT (Heterojunction) combines crystalline silicon with amorphous silicon layers, delivering the best temperature coefficient and bifacial gains, but at higher manufacturing cost. Both are equivalent-generation technologies.
