Specifications Breakdown
Module Efficiency
The JA Solar DeepBlue 4.0 Pro 460W achieves 22.4% module efficiency compared to LONGi Hi-MO X6 Max 470W's 22.3%, meaning JA Solar DeepBlue 4.0 Pro 460W converts 0.1 percentage points more sunlight into electricity per square meter. In practical terms, the JA Solar DeepBlue 4.0 Pro 460W produces 230.2 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 LONGi Hi-MO X6 Max 470W delivers 470W per panel versus 460W for the JA Solar DeepBlue 4.0 Pro 460W, a 10W difference per module. To build an 8 kW residential system, you would need 18 JA Solar DeepBlue 4.0 Pro 460W panels or 18 LONGi Hi-MO X6 Max 470W 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
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 JA Solar DeepBlue 4.0 Pro 460W 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 JA Solar DeepBlue 4.0 Pro 460W; 1% first year then 0.4%/year for LONGi Hi-MO X6 Max 470W), after 25 years the JA Solar DeepBlue 4.0 Pro 460W 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 JA Solar DeepBlue 4.0 Pro 460W measures 1762×1134×30mm and weighs 23 kg, while the LONGi Hi-MO X6 Max 470W measures 1762×1134×30mm at 23.5 kg. 2.00 m² of panel area for the JA Solar DeepBlue 4.0 Pro 460W versus 2.00 m² for the LONGi Hi-MO X6 Max 470W. 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.
