Specifications Breakdown
Module Efficiency
The JinkoSolar Tiger Neo 440W achieves 22.2% module efficiency compared to Panasonic EVPV400H's 21.2%, meaning JinkoSolar Tiger Neo 440W converts 1.0 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 Panasonic EVPV400H produces 204.8 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 JinkoSolar Tiger Neo 440W delivers 440W per panel versus 400W for the Panasonic EVPV400H, a 40W difference per module. To build an 8 kW residential system, you would need 19 JinkoSolar Tiger Neo 440W panels or 20 Panasonic EVPV400H 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 Panasonic EVPV400H has a temperature coefficient of -0.26%/°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 Panasonic EVPV400H 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 JinkoSolar Tiger Neo 440W is backed by a 15-year product warranty and 30-year performance guarantee, while the Panasonic EVPV400H offers 25-year product and 25-year performance coverage. The Panasonic EVPV400H 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; 0.5% first year then 0.35%/year for Panasonic EVPV400H), after 25 years the JinkoSolar Tiger Neo 440W should retain approximately 89.4% of original output versus 91.1% for the Panasonic EVPV400H. This 1.7 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 Panasonic EVPV400H measures 1722×1134×30mm at 21 kg. 1.95 m² of panel area for the JinkoSolar Tiger Neo 440W versus 1.95 m² for the Panasonic EVPV400H. 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.
