Specifications Breakdown

Module Efficiency

The Waaree WS-440 achieves 21.8% module efficiency compared to Hanwha Q.TRON G11S 410W's 21.3%, meaning Waaree WS-440 converts 0.5 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 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 Waaree WS-440 delivers 440W per panel versus 410W for the Hanwha Q.TRON G11S 410W, a 30W difference per module. To build an 8 kW residential system, you would need 20 Hanwha Q.TRON G11S 410W panels or 19 Waaree WS-440 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

The Hanwha Q.TRON G11S 410W has a temperature coefficient of -0.29%/°C versus -0.3%/°C for the Waaree WS-440. 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 Waaree WS-440 offers 12-year product and 25-year performance coverage. The Hanwha Q.TRON G11S 410W 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 Hanwha Q.TRON G11S 410W; 1% first year then 0.4%/year for Waaree WS-440), after 25 years the Hanwha Q.TRON G11S 410W 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 Hanwha Q.TRON G11S 410W measures 1722×1134×30mm and weighs 20.8 kg, while the Waaree WS-440 measures 1722×1134×30mm at 21.5 kg. 1.95 m² of panel area for the Hanwha Q.TRON G11S 410W versus 1.95 m² for the Waaree WS-440. 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.
