Specifications Breakdown
Module Efficiency
Both the Canadian Solar TOPBiHiKu7 580W and Risen Energy Titan S 440W share identical 22.1% module efficiency, producing comparable power per unit area. The Canadian Solar TOPBiHiKu7 580W generates 224.5 W/m² while the Risen Energy Titan S 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 Canadian Solar TOPBiHiKu7 580W delivers 580W per panel versus 440W for the Risen Energy Titan S 440W, a 140W difference per module. To build an 8 kW residential system, you would need 14 Canadian Solar TOPBiHiKu7 580W panels or 19 Risen Energy Titan S 440W panels. Choosing the higher-wattage option saves 5 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 -0.29%/°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 Canadian Solar TOPBiHiKu7 580W is backed by a 15-year product warranty and 30-year performance guarantee, while the Risen Energy Titan S 440W offers 12-year product and 25-year performance coverage. The Canadian Solar TOPBiHiKu7 580W 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 Canadian Solar TOPBiHiKu7 580W; 1% first year then 0.4%/year for Risen Energy Titan S 440W), after 25 years the Canadian Solar TOPBiHiKu7 580W should retain approximately 89.4% of original output versus 89.4% for the Risen Energy Titan S 440W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Canadian Solar TOPBiHiKu7 580W measures 2278×1134×35mm and weighs 28.5 kg, while the Risen Energy Titan S 440W measures 1722×1134×30mm at 21.5 kg. 2.58 m² of panel area for the Canadian Solar TOPBiHiKu7 580W versus 1.95 m² for the Risen Energy Titan S 440W. The Risen Energy Titan S 440W 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 Risen Energy Titan S 440W may be easier to fit on irregularly shaped or space-limited rooftops.
