Specifications Breakdown

Module Efficiency

The Panasonic EverVolt H 410W achieves 21.6% module efficiency compared to Canadian Solar HiKu6 455W's 21.4%, meaning Panasonic EverVolt H 410W converts 0.2 percentage points more sunlight into electricity per square meter. In practical terms, the Canadian Solar HiKu6 455W produces 227.7 watts per square meter of panel area while the Panasonic EverVolt H 410W produces 210.0 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 Canadian Solar HiKu6 455W delivers 455W per panel versus 410W for the Panasonic EverVolt H 410W, a 45W difference per module. To build an 8 kW residential system, you would need 18 Canadian Solar HiKu6 455W panels or 20 Panasonic EverVolt H 410W panels. Choosing the higher-wattage option saves 2 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

The Panasonic EverVolt H 410W has a temperature coefficient of -0.26%/°C versus -0.34%/°C for the Canadian Solar HiKu6 455W. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Panasonic EverVolt H 410W retains 94.8% 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 Canadian Solar HiKu6 455W is backed by a 12-year product warranty and 25-year performance guarantee, while the Panasonic EverVolt H 410W offers 25-year product and 25-year performance coverage. The Panasonic EverVolt H 410W provides 13 additional years of defect protection, covering manufacturing issues, material failures, and premature performance loss. Based on their published degradation rates (1.5% first year then 0.5%/year for Canadian Solar HiKu6 455W; 0.5% first year then 0.35%/year for Panasonic EverVolt H 410W), after 25 years the Canadian Solar HiKu6 455W should retain approximately 86.5% of original output versus 91.1% for the Panasonic EverVolt H 410W. This 4.6 percentage point gap in end-of-life output meaningfully impacts lifetime energy economics.

Physical Dimensions & Weight

The Canadian Solar HiKu6 455W measures 1762×1134×30mm and weighs 23 kg, while the Panasonic EverVolt H 410W measures 1722×1134×30mm at 21.5 kg. 2.00 m² of panel area for the Canadian Solar HiKu6 455W versus 1.95 m² for the Panasonic EverVolt H 410W. 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.
