Specifications Breakdown
Module Efficiency
The Hyundai HiE-S485VG achieves 22% module efficiency compared to Hanwha Q.TRON G11S 410W's 21.3%, meaning Hyundai HiE-S485VG converts 0.7 percentage points more sunlight into electricity per square meter. In practical terms, the Hanwha Q.TRON G11S 410W produces 210.0 watts per square meter of panel area while the Hyundai HiE-S485VG produces 222.9 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 Hyundai HiE-S485VG delivers 485W per panel versus 410W for the Hanwha Q.TRON G11S 410W, a 75W difference per module. To build an 8 kW residential system, you would need 20 Hanwha Q.TRON G11S 410W panels or 17 Hyundai HiE-S485VG panels. Choosing the higher-wattage option saves 3 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
The Hanwha Q.TRON G11S 410W has a temperature coefficient of -0.29%/°C versus -0.3%/°C for the Hyundai HiE-S485VG. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Hanwha Q.TRON G11S 410W retains 94.2% of its rated power while the other retains 94.0%. While the numerical gap is modest, it still accumulates over decades of summer production, especially in southern latitudes with prolonged peak heat hours.
Warranty Coverage
The Hanwha Q.TRON G11S 410W is backed by a 25-year product warranty and 25-year performance guarantee, while the Hyundai HiE-S485VG offers 25-year product and 25-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1% first year then 0.4%/year for Hanwha Q.TRON G11S 410W; 1% first year then 0.4%/year for Hyundai HiE-S485VG), after 25 years the Hanwha Q.TRON G11S 410W should retain approximately 89.4% of original output versus 89.4% for the Hyundai HiE-S485VG. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Hanwha Q.TRON G11S 410W measures 1722×1134×30mm and weighs 20.8 kg, while the Hyundai HiE-S485VG measures 2094×1039×35mm at 24.5 kg. 1.95 m² of panel area for the Hanwha Q.TRON G11S 410W versus 2.18 m² for the Hyundai HiE-S485VG. The Hanwha Q.TRON G11S 410W is 3.7 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 74 kg. The more compact Hanwha Q.TRON G11S 410W may be easier to fit on irregularly shaped or space-limited rooftops.
