Specifications Breakdown
Module Efficiency
The LONGi Hi-MO X6 Max 470W achieves 22.3% module efficiency compared to Yingli Solar PANDA 3.0 PRO 430W's 21.6%, meaning LONGi Hi-MO X6 Max 470W converts 0.7 percentage points more sunlight into electricity per square meter. In practical terms, the Yingli Solar PANDA 3.0 PRO 430W produces 220.2 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 430W for the Yingli Solar PANDA 3.0 PRO 430W, a 40W difference per module. To build an 8 kW residential system, you would need 19 Yingli Solar PANDA 3.0 PRO 430W panels or 18 LONGi Hi-MO X6 Max 470W panels. Choosing the higher-wattage option saves 1 panel, 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 Yingli Solar PANDA 3.0 PRO 430W is backed by a 12-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. The LONGi Hi-MO X6 Max 470W provides 3 additional years of defect protection, covering manufacturing issues, material failures, and premature performance loss. Based on their published degradation rates (1% first year then 0.4%/year for Yingli Solar PANDA 3.0 PRO 430W; 1% first year then 0.4%/year for LONGi Hi-MO X6 Max 470W), after 25 years the Yingli Solar PANDA 3.0 PRO 430W 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 Yingli Solar PANDA 3.0 PRO 430W measures 1722×1134×30mm and weighs 21.5 kg, while the LONGi Hi-MO X6 Max 470W measures 1762×1134×30mm at 23.5 kg. 1.95 m² of panel area for the Yingli Solar PANDA 3.0 PRO 430W versus 2.00 m² for the LONGi Hi-MO X6 Max 470W. The Yingli Solar PANDA 3.0 PRO 430W is 2.0 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 40 kg. Similar footprints mean both panels fit comparably on standard residential rooftop configurations.
