Specifications Breakdown
Module Efficiency
The Risen Energy Hyper-ion HJT 700W achieves 23% module efficiency compared to Panasonic EverVolt 410's 21.5%, meaning Risen Energy Hyper-ion HJT 700W converts 1.5 percentage points more sunlight into electricity per square meter. In practical terms, the Panasonic EverVolt 410 produces 210.0 watts per square meter of panel area while the Risen Energy Hyper-ion HJT 700W produces 225.3 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 Risen Energy Hyper-ion HJT 700W delivers 700W per panel versus 410W for the Panasonic EverVolt 410, a 290W difference per module. To build an 8 kW residential system, you would need 20 Panasonic EverVolt 410 panels or 12 Risen Energy Hyper-ion HJT 700W panels. Choosing the higher-wattage option saves 8 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 Risen Energy Hyper-ion HJT 700W has a temperature coefficient of -0.25%/°C versus -0.26%/°C for the Panasonic EverVolt 410. On a hot summer day when cell temperature reaches 65°C (40°C above the 25°C STC baseline), the Risen Energy Hyper-ion HJT 700W retains 95.0% of its rated power while the other retains 94.8%. While the numerical gap is modest, it still accumulates over decades of summer production, especially in southern latitudes with prolonged peak heat hours.
Warranty Coverage
The Panasonic EverVolt 410 is backed by a 25-year product warranty and 25-year performance guarantee, while the Risen Energy Hyper-ion HJT 700W offers 15-year product and 30-year performance coverage. The Panasonic EverVolt 410 provides 10 additional years of defect protection, covering manufacturing issues, material failures, and premature performance loss. Based on their published degradation rates (0.5% first year then 0.35%/year for Panasonic EverVolt 410; 0.5% first year then 0.35%/year for Risen Energy Hyper-ion HJT 700W), after 25 years the Panasonic EverVolt 410 should retain approximately 91.1% of original output versus 91.1% for the Risen Energy Hyper-ion HJT 700W. The end-of-life output levels are closely matched.
Physical Dimensions & Weight
The Panasonic EverVolt 410 measures 1722×1134×30mm and weighs 21.5 kg, while the Risen Energy Hyper-ion HJT 700W measures 2384×1303×35mm at 35.5 kg. 1.95 m² of panel area for the Panasonic EverVolt 410 versus 3.11 m² for the Risen Energy Hyper-ion HJT 700W. The Panasonic EverVolt 410 is 14.0 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 280 kg. The more compact Panasonic EverVolt 410 may be easier to fit on irregularly shaped or space-limited rooftops.
