Specifications Breakdown
Module Efficiency
Both the LONGi Hi-MO 7 590W and JinkoSolar Tiger Neo 615W share identical 22.8% module efficiency, producing comparable power per unit area. The LONGi Hi-MO 7 590W generates 228.4 W/m² while the JinkoSolar Tiger Neo 615W generates 227.5 W/m² based on their respective panel dimensions. With matched efficiency, neither panel holds a density advantage for space-constrained rooftop installations, so other factors like warranty coverage and temperature performance become the deciding metrics.
Power Output
The JinkoSolar Tiger Neo 615W delivers 615W per panel versus 590W for the LONGi Hi-MO 7 590W, a 25W difference per module. To build an 8 kW residential system, you would need 14 LONGi Hi-MO 7 590W panels or 14 JinkoSolar Tiger Neo 615W 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 -0.28%/°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 94.4% of rated power. Neither panel has a thermal performance advantage, which makes this specification a non-factor in the comparison.
Warranty Coverage
The LONGi Hi-MO 7 590W is backed by a 12-year product warranty and 30-year performance guarantee, while the JinkoSolar Tiger Neo 615W offers 15-year product and 30-year performance coverage. The JinkoSolar Tiger Neo 615W provides 3 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 LONGi Hi-MO 7 590W; 1% first year then 0.4%/year for JinkoSolar Tiger Neo 615W), after 25 years the LONGi Hi-MO 7 590W should retain approximately 89.4% of original output versus 89.4% for the JinkoSolar Tiger Neo 615W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The LONGi Hi-MO 7 590W measures 2278×1134×35mm and weighs 28.8 kg, while the JinkoSolar Tiger Neo 615W measures 2384×1134×35mm at 31.5 kg. 2.58 m² of panel area for the LONGi Hi-MO 7 590W versus 2.70 m² for the JinkoSolar Tiger Neo 615W. The LONGi Hi-MO 7 590W is 2.7 kg lighter per panel, which reduces structural load requirements on the roof and makes handling easier during installation. For a 20-panel system, that is a total weight difference of 54 kg. The more compact LONGi Hi-MO 7 590W may be easier to fit on irregularly shaped or space-limited rooftops.
