Specifications Breakdown
Module Efficiency
The Maxeon Maxeon 6 AC 440W achieves 22.5% module efficiency compared to JinkoSolar Tiger Neo 440W's 22.2%, meaning Maxeon Maxeon 6 AC 440W converts 0.3 percentage points more sunlight into electricity per square meter. In practical terms, the JinkoSolar Tiger Neo 440W produces 225.3 watts per square meter of panel area while the Maxeon Maxeon 6 AC 440W produces 203.5 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 440W under standard test conditions (STC), requiring 19 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 Maxeon Maxeon 6 AC 440W has a temperature coefficient of -0.27%/°C versus -0.29%/°C for the JinkoSolar Tiger Neo 440W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Maxeon Maxeon 6 AC 440W retains 94.6% 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 JinkoSolar Tiger Neo 440W is backed by a 15-year product warranty and 30-year performance guarantee, while the Maxeon Maxeon 6 AC 440W offers 25-year product and 25-year performance coverage. The Maxeon Maxeon 6 AC 440W provides 10 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 JinkoSolar Tiger Neo 440W; 0.25% first year then 0.25%/year for Maxeon Maxeon 6 AC 440W), after 25 years the JinkoSolar Tiger Neo 440W should retain approximately 89.4% of original output versus 93.8% for the Maxeon Maxeon 6 AC 440W. This 4.4 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The JinkoSolar Tiger Neo 440W measures 1722×1134×30mm and weighs 21.5 kg, while the Maxeon Maxeon 6 AC 440W measures 2067×1046×30mm at 22 kg. 1.95 m² of panel area for the JinkoSolar Tiger Neo 440W versus 2.16 m² for the Maxeon Maxeon 6 AC 440W. Their weights are closely matched, so neither panel imposes a significantly different structural load on the mounting system. The more compact JinkoSolar Tiger Neo 440W may be easier to fit on irregularly shaped or space-limited rooftops.
