Specifications Breakdown
Module Efficiency
The LONGi Hi-MO 6 Explorer 430W achieves 21.6% module efficiency compared to Trina Solar DE09R 430W's 21%, meaning LONGi Hi-MO 6 Explorer 430W converts 0.6 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 Trina Solar DE09R 430W produces 220.2 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 430W 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
Both panels share an identical temperature coefficient of -0.34%/°C, meaning they lose power at the same rate as cell temperature rises above the 25°C standard test baseline. At 65°C cell temperature, both retain 93.2% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The LONGi Hi-MO 6 Explorer 430W is backed by a 12-year product warranty and 25-year performance guarantee, while the Trina Solar DE09R 430W 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; 1.5% first year then 0.5%/year for Trina Solar DE09R 430W), after 25 years the LONGi Hi-MO 6 Explorer 430W should retain approximately 86.5% of original output versus 86.5% for the Trina Solar DE09R 430W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The LONGi Hi-MO 6 Explorer 430W measures 1722×1134×30mm and weighs 21 kg, while the Trina Solar DE09R 430W 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 Trina Solar DE09R 430W. 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.
