Specifications Breakdown

Module Efficiency

The Risen Energy Titan S 440W achieves 22.1% module efficiency compared to LONGi Hi-MO 6 Explorer 430W's 21.6%, meaning Risen Energy Titan S 440W converts 0.5 percentage points more sunlight into electricity per square meter. In practical terms, the LONGi Hi-MO 6 Explorer 430W produces 220.2 watts per square meter of panel area while the Risen Energy Titan S 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

The Risen Energy Titan S 440W delivers 440W per panel versus 430W for the LONGi Hi-MO 6 Explorer 430W, a 10W difference per module. To build an 8 kW residential system, you would need 19 LONGi Hi-MO 6 Explorer 430W panels or 19 Risen Energy Titan S 440W panels. Despite the per-panel wattage difference, both require the same number of panels for this system size due to rounding. Higher wattage per panel is particularly valuable for commercial-scale installations where panel count directly impacts balance-of-system costs.

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 Explorer 430W. 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 LONGi Hi-MO 6 Explorer 430W is backed by a 12-year product warranty and 25-year performance guarantee, while the Risen Energy Titan S 440W offers 12-year product and 25-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1.5% first year then 0.5%/year for LONGi Hi-MO 6 Explorer 430W; 1% first year then 0.4%/year for Risen Energy Titan S 440W), after 25 years the LONGi Hi-MO 6 Explorer 430W should retain approximately 86.5% of original output versus 89.4% for the Risen Energy Titan S 440W. This 2.9 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.

Physical Dimensions & Weight

The LONGi Hi-MO 6 Explorer 430W measures 1722×1134×30mm and weighs 21 kg, while the Risen Energy Titan S 440W measures 1722×1134×30mm at 21.5 kg. 1.95 m² of panel area for the LONGi Hi-MO 6 Explorer 430W versus 1.95 m² for the Risen Energy Titan S 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.
