Specifications Breakdown
Module Efficiency
The Panasonic EverVolt 410 achieves 21.5% module efficiency compared to Mission Solar MSE PERC 72 385W's 20%, meaning Panasonic EverVolt 410 converts 1.5 percentage points more sunlight into electricity per square meter. In practical terms, the Panasonic EverVolt 410 produces 210.0 watts per square meter of panel area while the Mission Solar MSE PERC 72 385W produces 149.0 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 410 delivers 410W per panel versus 385W for the Mission Solar MSE PERC 72 385W, a 25W difference per module. To build an 8 kW residential system, you would need 20 Panasonic EverVolt 410 panels or 21 Mission Solar MSE PERC 72 385W 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 Panasonic EverVolt 410 has a temperature coefficient of -0.26%/°C versus -0.35%/°C for the Mission Solar MSE PERC 72 385W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Panasonic EverVolt 410 retains 94.8% of its rated power while the other retains 93.0%. 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 Panasonic EverVolt 410 is backed by a 25-year product warranty and 25-year performance guarantee, while the Mission Solar MSE PERC 72 385W offers 25-year product and 25-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 410; 1% first year then 0.4%/year for Mission Solar MSE PERC 72 385W), after 25 years the Panasonic EverVolt 410 should retain approximately 91.1% of original output versus 89.4% for the Mission Solar MSE PERC 72 385W. This 1.7 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Panasonic EverVolt 410 measures 1722×1134×30mm and weighs 21.5 kg, while the Mission Solar MSE PERC 72 385W measures 2278×1134×35mm at 26 kg. 1.95 m² of panel area for the Panasonic EverVolt 410 versus 2.58 m² for the Mission Solar MSE PERC 72 385W. The Panasonic EverVolt 410 is 4.5 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 90 kg. The more compact Panasonic EverVolt 410 may be easier to fit on irregularly shaped or space-limited rooftops.
