Specifications Breakdown
Module Efficiency
The ZNShine Solar ZXM7-NHLD144 580W achieves 22.4% module efficiency compared to LONGi Hi-MO X6 Max 470W's 22.3%, meaning ZNShine Solar ZXM7-NHLD144 580W converts 0.1 percentage points more sunlight into electricity per square meter. In practical terms, the ZNShine Solar ZXM7-NHLD144 580W produces 224.5 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 ZNShine Solar ZXM7-NHLD144 580W delivers 580W per panel versus 470W for the LONGi Hi-MO X6 Max 470W, a 110W difference per module. To build an 8 kW residential system, you would need 14 ZNShine Solar ZXM7-NHLD144 580W 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 ZNShine Solar ZXM7-NHLD144 580W 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 ZNShine Solar ZXM7-NHLD144 580W; 1% first year then 0.4%/year for LONGi Hi-MO X6 Max 470W), after 25 years the ZNShine Solar ZXM7-NHLD144 580W 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 ZNShine Solar ZXM7-NHLD144 580W measures 2278×1134×35mm and weighs 28.5 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 ZNShine Solar ZXM7-NHLD144 580W versus 2.00 m² for the LONGi Hi-MO X6 Max 470W. The LONGi Hi-MO X6 Max 470W is 5.0 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 100 kg. The more compact LONGi Hi-MO X6 Max 470W may be easier to fit on irregularly shaped or space-limited rooftops.
