Specifications Breakdown
Module Efficiency
The Hyundai HiE-S485VG achieves 22% module efficiency compared to Waaree WS-440's 21.8%, meaning Hyundai HiE-S485VG converts 0.2 percentage points more sunlight into electricity per square meter. In practical terms, the Hyundai HiE-S485VG produces 222.9 watts per square meter of panel area while the Waaree WS-440 produces 225.3 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 440W for the Waaree WS-440, a 45W difference per module. To build an 8 kW residential system, you would need 17 Hyundai HiE-S485VG panels or 19 Waaree WS-440 panels. Choosing the higher-wattage option saves 2 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 -0.3%/°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 94.0% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The Hyundai HiE-S485VG is backed by a 25-year product warranty and 25-year performance guarantee, while the Waaree WS-440 offers 12-year product and 25-year performance coverage. The Hyundai HiE-S485VG provides 13 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 Hyundai HiE-S485VG; 1% first year then 0.4%/year for Waaree WS-440), after 25 years the Hyundai HiE-S485VG should retain approximately 89.4% of original output versus 89.4% for the Waaree WS-440. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Hyundai HiE-S485VG measures 2094×1039×35mm and weighs 24.5 kg, while the Waaree WS-440 measures 1722×1134×30mm at 21.5 kg. 2.18 m² of panel area for the Hyundai HiE-S485VG versus 1.95 m² for the Waaree WS-440. The Waaree WS-440 is 3.0 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 60 kg. The more compact Waaree WS-440 may be easier to fit on irregularly shaped or space-limited rooftops.
