Specifications Breakdown
Module Efficiency
The JinkoSolar Tiger Neo 440W achieves 22.2% module efficiency compared to JinkoSolar Tiger Neo S 430W's 22%, meaning JinkoSolar Tiger Neo 440W converts 0.2 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 JinkoSolar Tiger Neo S 430W produces 220.2 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 430W for the JinkoSolar Tiger Neo S 430W, a 10W difference per module. To build an 8 kW residential system, you would need 19 JinkoSolar Tiger Neo 440W panels or 19 JinkoSolar Tiger Neo S 430W panels. Despite the per-panel wattage difference, both require the same number of panels for this system size due to rounding. Higher wattage per panel is particularly valuable for commercial-scale installations where panel count directly impacts balance-of-system costs.
Temperature Coefficient
Both panels share an identical temperature coefficient of -0.29%/°C, meaning they lose power at the same rate as cell temperature rises above the 25°C standard test baseline. At 65°C cell temperature, both retain 94.2% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The JinkoSolar Tiger Neo 440W is backed by a 15-year product warranty and 30-year performance guarantee, while the JinkoSolar Tiger Neo S 430W offers 15-year product and 30-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1% first year then 0.4%/year for JinkoSolar Tiger Neo 440W; 1% first year then 0.4%/year for JinkoSolar Tiger Neo S 430W), after 25 years the JinkoSolar Tiger Neo 440W should retain approximately 89.4% of original output versus 89.4% for the JinkoSolar Tiger Neo S 430W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The JinkoSolar Tiger Neo 440W measures 1722×1134×30mm and weighs 21.5 kg, while the JinkoSolar Tiger Neo S 430W 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 JinkoSolar Tiger Neo S 430W. 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.
