Specifications Breakdown
Module Efficiency
The Trina Solar Vertex N 590W achieves 22.5% module efficiency compared to LONGi Hi-MO X6 Max 470W's 22.3%, meaning Trina Solar Vertex N 590W converts 0.2 percentage points more sunlight into electricity per square meter. In practical terms, the Trina Solar Vertex N 590W produces 228.4 watts per square meter of panel area while the LONGi Hi-MO X6 Max 470W produces 235.2 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
The Trina Solar Vertex N 590W delivers 590W per panel versus 470W for the LONGi Hi-MO X6 Max 470W, a 120W difference per module. To build an 8 kW residential system, you would need 14 Trina Solar Vertex N 590W panels or 18 LONGi Hi-MO X6 Max 470W panels. Choosing the higher-wattage option saves 4 panels, 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
Both panels share an identical temperature coefficient of -0.29%/°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 94.2% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The Trina Solar Vertex N 590W is backed by a 15-year product warranty and 30-year performance guarantee, while the LONGi Hi-MO X6 Max 470W offers 15-year product and 30-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1% first year then 0.4%/year for Trina Solar Vertex N 590W; 1% first year then 0.4%/year for LONGi Hi-MO X6 Max 470W), after 25 years the Trina Solar Vertex N 590W should retain approximately 89.4% of original output versus 89.4% for the LONGi Hi-MO X6 Max 470W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Trina Solar Vertex N 590W measures 2278×1134×35mm and weighs 29 kg, while the LONGi Hi-MO X6 Max 470W measures 1762×1134×30mm at 23.5 kg. 2.58 m² of panel area for the Trina Solar Vertex N 590W versus 2.00 m² for the LONGi Hi-MO X6 Max 470W. The LONGi Hi-MO X6 Max 470W is 5.5 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 110 kg. The more compact LONGi Hi-MO X6 Max 470W may be easier to fit on irregularly shaped or space-limited rooftops.
