Specifications Breakdown
Module Efficiency
The Risen Energy Titan S 440W achieves 22.1% module efficiency compared to LONGi Hi-MO 6 Artist 440W's 22%, meaning Risen Energy Titan S 440W converts 0.1 percentage points more sunlight into electricity per square meter. In practical terms, the Risen Energy Titan S 440W produces 225.3 watts per square meter of panel area while the LONGi Hi-MO 6 Artist 440W produces 225.3 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
Both panels are rated at 440W under standard test conditions (STC), requiring 19 panels each to build an 8 kW system. With identical wattage ratings, the power output dimension is a draw and does not favor either panel. The real differentiators become efficiency density, temperature behavior, and long-term degradation rates which determine actual field performance beyond the nameplate rating.
Temperature Coefficient
The Risen Energy Titan S 440W 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 Risen Energy Titan S 440W 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 Risen Energy Titan S 440W is backed by a 12-year product warranty and 25-year performance guarantee, while the LONGi Hi-MO 6 Artist 440W offers 12-year product and 25-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1% first year then 0.4%/year for Risen Energy Titan S 440W; 1.5% first year then 0.5%/year for LONGi Hi-MO 6 Artist 440W), after 25 years the Risen Energy Titan S 440W should retain approximately 89.4% of original output versus 86.5% for the LONGi Hi-MO 6 Artist 440W. This 2.9 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The Risen Energy Titan S 440W measures 1722×1134×30mm and weighs 21.5 kg, while the LONGi Hi-MO 6 Artist 440W measures 1722×1134×30mm at 21 kg. 1.95 m² of panel area for the Risen Energy Titan S 440W versus 1.95 m² for the LONGi Hi-MO 6 Artist 440W. 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.
