Specifications Breakdown

Module Efficiency

Both the Talesun HiPro TPD-M12-430 and LONGi Hi-MO 6 Artist 440W share identical 22% module efficiency, producing comparable power per unit area. The Talesun HiPro TPD-M12-430 generates 220.2 W/m² while the LONGi Hi-MO 6 Artist 440W generates 225.3 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 LONGi Hi-MO 6 Artist 440W delivers 440W per panel versus 430W for the Talesun HiPro TPD-M12-430, a 10W difference per module. To build an 8 kW residential system, you would need 19 Talesun HiPro TPD-M12-430 panels or 19 LONGi Hi-MO 6 Artist 440W 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

The Talesun HiPro TPD-M12-430 has a temperature coefficient of -0.29%/°C versus -0.34%/°C for the LONGi Hi-MO 6 Artist 440W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Talesun HiPro TPD-M12-430 retains 94.2% of its rated power while the other retains 93.2%. 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 Talesun HiPro TPD-M12-430 is backed by a 15-year product warranty and 30-year performance guarantee, while the LONGi Hi-MO 6 Artist 440W offers 12-year product and 25-year performance coverage. The Talesun HiPro TPD-M12-430 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 Talesun HiPro TPD-M12-430; 1.5% first year then 0.5%/year for LONGi Hi-MO 6 Artist 440W), after 25 years the Talesun HiPro TPD-M12-430 should retain approximately 89.4% of original output versus 86.5% for the LONGi Hi-MO 6 Artist 440W. This 2.9 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.

Physical Dimensions & Weight

The Talesun HiPro TPD-M12-430 measures 1722×1134×30mm and weighs 21.5 kg, while the LONGi Hi-MO 6 Artist 440W measures 1722×1134×30mm at 21 kg. 1.95 m² of panel area for the Talesun HiPro TPD-M12-430 versus 1.95 m² for the LONGi Hi-MO 6 Artist 440W. 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.
