Specifications Breakdown
Module Efficiency
Both the Astronergy ASTRO N7 580W and ZNShine Solar ZXM7-NHLD144 580W share identical 22.4% module efficiency, producing comparable power per unit area. The Astronergy ASTRO N7 580W generates 224.5 W/m² while the ZNShine Solar ZXM7-NHLD144 580W generates 224.5 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
Both panels are rated at 580W under standard test conditions (STC), requiring 14 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
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 Astronergy ASTRO N7 580W is backed by a 15-year product warranty and 30-year performance guarantee, while the ZNShine Solar ZXM7-NHLD144 580W 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 Astronergy ASTRO N7 580W; 1% first year then 0.4%/year for ZNShine Solar ZXM7-NHLD144 580W), after 25 years the Astronergy ASTRO N7 580W should retain approximately 89.4% of original output versus 89.4% for the ZNShine Solar ZXM7-NHLD144 580W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Astronergy ASTRO N7 580W measures 2278×1134×35mm and weighs 28.5 kg, while the ZNShine Solar ZXM7-NHLD144 580W measures 2278×1134×35mm at 28.5 kg. 2.58 m² of panel area for the Astronergy ASTRO N7 580W versus 2.58 m² for the ZNShine Solar ZXM7-NHLD144 580W. 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.
