Specifications Breakdown
Module Efficiency
The REC Alpha Pure-R 460W achieves 22.2% module efficiency compared to Aptos Solar DNA-120-MF10 460W's 21.26%, meaning REC Alpha Pure-R 460W converts 0.9 percentage points more sunlight into electricity per square meter. In practical terms, the REC Alpha Pure-R 460W produces 220.9 watts per square meter of panel area while the Aptos Solar DNA-120-MF10 460W produces 212.6 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
Both panels are rated at 460W under standard test conditions (STC), requiring 18 panels each to build an 8 kW system. With identical wattage ratings, the power output dimension is a draw and does not favor either panel. The real differentiators become efficiency density, temperature behavior, and long-term degradation rates which determine actual field performance beyond the nameplate rating.
Temperature Coefficient
The REC Alpha Pure-R 460W has a temperature coefficient of -0.26%/°C versus -0.35%/°C for the Aptos Solar DNA-120-MF10 460W. 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 93.0%. This difference is particularly significant in hot climates such as the American Southwest, the Middle East, and Southeast Asia, where panels routinely operate 30-40°C above STC for several hours each day. Over the system lifetime, the cumulative energy advantage from a better temperature coefficient can amount to 2-4% of total production.
Warranty Coverage
The REC Alpha Pure-R 460W is backed by a 25-year product warranty and 25-year performance guarantee, while the Aptos Solar DNA-120-MF10 460W offers 30-year product and 30-year performance coverage. The Aptos Solar DNA-120-MF10 460W provides 5 additional years of defect protection, covering manufacturing issues, material failures, and premature performance loss. Based on their published degradation rates (0.5% first year then 0.35%/year for REC Alpha Pure-R 460W; 1% first year then 0.54%/year for Aptos Solar DNA-120-MF10 460W), after 25 years the REC Alpha Pure-R 460W should retain approximately 91.1% of original output versus 86.0% for the Aptos Solar DNA-120-MF10 460W. This 5.1 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 Aptos Solar DNA-120-MF10 460W measures 1908×1134×35mm at 24 kg. 2.08 m² of panel area for the REC Alpha Pure-R 460W versus 2.16 m² for the Aptos Solar DNA-120-MF10 460W. 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.
