Power Output
The REC Alpha Pure-R 460W delivers 460W per panel versus 410W for the Hanwha Q.TRON G11S 410W, a 50W difference per module. To build an 8 kW residential system, you would need 18 REC Alpha Pure-R 460W panels or 20 Hanwha Q.TRON G11S 410W 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
The REC Alpha Pure-R 460W has a temperature coefficient of -0.26%/°C versus -0.29%/°C for the Hanwha Q.TRON G11S 410W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the REC Alpha Pure-R 460W retains 94.8% of its rated power while the other retains 94.2%. 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 REC Alpha Pure-R 460W is backed by a 25-year product warranty and 25-year performance guarantee, while the Hanwha Q.TRON G11S 410W offers 25-year product and 25-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (0.5% first year then 0.35%/year for REC Alpha Pure-R 460W; 1% first year then 0.4%/year for Hanwha Q.TRON G11S 410W), after 25 years the REC Alpha Pure-R 460W should retain approximately 91.1% of original output versus 89.4% for the Hanwha Q.TRON G11S 410W. This 1.7 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The REC Alpha Pure-R 460W measures 1728×1205×30mm and weighs 23 kg, while the Hanwha Q.TRON G11S 410W measures 1722×1134×30mm at 20.8 kg. 2.08 m² of panel area for the REC Alpha Pure-R 460W versus 1.95 m² for the Hanwha Q.TRON G11S 410W. The Hanwha Q.TRON G11S 410W is 2.2 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 44 kg. The more compact Hanwha Q.TRON G11S 410W may be easier to fit on irregularly shaped or space-limited rooftops.
