Power Output
The Seraphim SRP-445-BMA-HV delivers 445W per panel versus 440W for the LONGi Hi-MO 6 Artist 440W, a 5W difference per module. To build an 8 kW residential system, you would need 18 Seraphim SRP-445-BMA-HV panels or 19 LONGi Hi-MO 6 Artist 440W 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 Seraphim SRP-445-BMA-HV has a temperature coefficient of -0.29%/°C versus -0.34%/°C for the LONGi Hi-MO 6 Artist 440W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Seraphim SRP-445-BMA-HV retains 94.2% 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 Seraphim SRP-445-BMA-HV is backed by a 15-year product warranty and 30-year performance guarantee, while the LONGi Hi-MO 6 Artist 440W offers 12-year product and 25-year performance coverage.
