Specifications Breakdown
Module Efficiency
The Trina Solar Vertex N 590W achieves 22.5% module efficiency compared to Astronergy ASTRO N7 580W's 22.4%, meaning Trina Solar Vertex N 590W converts 0.1 percentage points more sunlight into electricity per square meter. In practical terms, the Trina Solar Vertex N 590W produces 228.4 watts per square meter of panel area while the Astronergy ASTRO N7 580W produces 224.5 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 Trina Solar Vertex N 590W delivers 590W per panel versus 580W for the Astronergy ASTRO N7 580W, a 10W difference per module. To build an 8 kW residential system, you would need 14 Trina Solar Vertex N 590W panels or 14 Astronergy ASTRO N7 580W 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 Trina Solar Vertex N 590W is backed by a 15-year product warranty and 30-year performance guarantee, while the Astronergy ASTRO N7 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 Trina Solar Vertex N 590W; 1% first year then 0.4%/year for Astronergy ASTRO N7 580W), after 25 years the Trina Solar Vertex N 590W should retain approximately 89.4% of original output versus 89.4% for the Astronergy ASTRO N7 580W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Trina Solar Vertex N 590W measures 2278×1134×35mm and weighs 29 kg, while the Astronergy ASTRO N7 580W measures 2278×1134×35mm at 28.5 kg. 2.58 m² of panel area for the Trina Solar Vertex N 590W versus 2.58 m² for the Astronergy ASTRO N7 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.
