Power Output
The Phono Solar DrivenStar 545W delivers 545W per panel versus 430W for the LONGi Hi-MO 6 Explorer 430W, a 115W difference per module. To build an 8 kW residential system, you would need 19 LONGi Hi-MO 6 Explorer 430W panels or 15 Phono Solar DrivenStar 545W panels. Choosing the higher-wattage option saves 4 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
Both panels share an identical temperature coefficient of -0.34%/°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 93.2% 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 6 Explorer 430W is backed by a 12-year product warranty and 25-year performance guarantee, while the Phono Solar DrivenStar 545W offers 12-year product and 25-year performance coverage. Both offer identical product warranty duration. Based on their published degradation rates (1.5% first year then 0.5%/year for LONGi Hi-MO 6 Explorer 430W; 1.5% first year then 0.5%/year for Phono Solar DrivenStar 545W), after 25 years the LONGi Hi-MO 6 Explorer 430W should retain approximately 86.5% of original output versus 86.5% for the Phono Solar DrivenStar 545W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The LONGi Hi-MO 6 Explorer 430W measures 1722×1134×30mm and weighs 21 kg, while the Phono Solar DrivenStar 545W measures 2278×1134×35mm at 28 kg. 1.95 m² of panel area for the LONGi Hi-MO 6 Explorer 430W versus 2.58 m² for the Phono Solar DrivenStar 545W. The LONGi Hi-MO 6 Explorer 430W is 7.0 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 140 kg. The more compact LONGi Hi-MO 6 Explorer 430W may be easier to fit on irregularly shaped or space-limited rooftops.
