Specifications Breakdown
Module Efficiency
Both the Silfab SIL-410-BG 410W and Meyer Burger Glass 390W share identical 21.2% module efficiency, producing comparable power per unit area. The Silfab SIL-410-BG 410W generates 210.0 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 Silfab SIL-410-BG 410W delivers 410W per panel versus 390W for the Meyer Burger Glass 390W, a 20W difference per module. To build an 8 kW residential system, you would need 20 Silfab SIL-410-BG 410W 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
The Meyer Burger Glass 390W has a temperature coefficient of -0.26%/°C versus -0.34%/°C for the Silfab SIL-410-BG 410W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Meyer Burger Glass 390W retains 94.8% of its rated power while the other retains 93.2%. This difference is particularly significant in hot climates such as the American Southwest, the Middle East, and Southeast Asia, where panels routinely operate 30-40°C above STC for several hours each day. Over the system lifetime, the cumulative energy advantage from a better temperature coefficient can amount to 2-4% of total production.
Warranty Coverage
The Silfab SIL-410-BG 410W is backed by a 25-year product warranty and 30-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 (1% first year then 0.4%/year for Silfab SIL-410-BG 410W; 1% first year then 0.25%/year for Meyer Burger Glass 390W), after 25 years the Silfab SIL-410-BG 410W should retain approximately 89.4% of original output versus 93.0% for the Meyer Burger Glass 390W. This 3.6 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Silfab SIL-410-BG 410W 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 Silfab SIL-410-BG 410W 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.
