Specifications Breakdown
Module Efficiency
The LONGi Hi-MO X6 445W achieves 22% module efficiency compared to JinkoSolar Tiger Pro 60HC 400W's 20.8%, meaning LONGi Hi-MO X6 445W converts 1.2 percentage points more sunlight into electricity per square meter. In practical terms, the LONGi Hi-MO X6 445W produces 227.9 watts per square meter of panel area while the JinkoSolar Tiger Pro 60HC 400W produces 200.2 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 LONGi Hi-MO X6 445W delivers 445W per panel versus 400W for the JinkoSolar Tiger Pro 60HC 400W, a 45W difference per module. To build an 8 kW residential system, you would need 18 LONGi Hi-MO X6 445W panels or 20 JinkoSolar Tiger Pro 60HC 400W 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 LONGi Hi-MO X6 445W has a temperature coefficient of -0.29%/°C versus -0.35%/°C for the JinkoSolar Tiger Pro 60HC 400W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the LONGi Hi-MO X6 445W retains 94.2% 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 LONGi Hi-MO X6 445W is backed by a 12-year product warranty and 25-year performance guarantee, while the JinkoSolar Tiger Pro 60HC 400W offers 12-year product and 25-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1% first year then 0.4%/year for LONGi Hi-MO X6 445W; 1.5% first year then 0.5%/year for JinkoSolar Tiger Pro 60HC 400W), after 25 years the LONGi Hi-MO X6 445W should retain approximately 89.4% of original output versus 86.5% for the JinkoSolar Tiger Pro 60HC 400W. This 2.9 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.
Physical Dimensions & Weight
The LONGi Hi-MO X6 445W measures 1722×1134×30mm and weighs 21.5 kg, while the JinkoSolar Tiger Pro 60HC 400W measures 1762×1134×30mm at 22 kg. 1.95 m² of panel area for the LONGi Hi-MO X6 445W versus 2.00 m² for the JinkoSolar Tiger Pro 60HC 400W. Their weights are closely matched, so neither panel imposes a significantly different structural load on the mounting system.
