SEG Solar SEG-465-BTB-BG 465–480W N-Type TOPCon Bifacial Solar Panel
Model SEG-465-BTB-BG | N-Type TOPCon | 120 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The SEG Solar SEG-465-BTB-BG is a high-performance bifacial solar panel designed for dependable energy production. It uses N-Type TOPCon half-cell technology to support strong output and improved efficiency. The module delivers 465 to 480 watts, depending on the selected version. Its bifacial design helps capture reflected light for additional rear-side generation. With a module efficiency of up to 22.17%, it is suited for residential, commercial, and utility applications. The panel also includes a 15-year product warranty and a 30-year power warranty. Its durable construction and low degradation rate support long-term performance. This model is a strong choice for customers seeking efficient solar technology with reliable output.
Key Benefits
High Power Output: Delivers a rated output range of 465 to 480 watts for strong system performance.
Advanced TOPCon Technology: N-Type TOPCon cells support improved efficiency and better long-term energy generation.
Bifacial Energy Gain: Rear-side power capture can add extra output when reflected light is available.
Low Degradation: The module is built for a 30-year power warranty with 87.4% retained output at the end of the term.
Durable Build: An anodized aluminium frame, anti-reflection glass, and IP68 junction box improve long-term reliability.
How It Works
This bifacial solar module converts sunlight into electricity through N-Type TOPCon half-cells. The front surface captures direct sunlight during normal operation. The rear surface can also absorb reflected light from bright roofs, ground surfaces, or open installations. That dual-sided design can increase total energy harvest in suitable environments. The half-cell format helps reduce resistance losses and supports stable electrical performance. Anti-reflection glass improves light transmission and helps the module absorb more available sunlight. The panel is engineered for a wide temperature range, which supports reliable operation in demanding climates. Its strong load ratings and certified construction help it perform consistently over time.
Front-Side Generation: Sunlight reaches the front glass and is converted into electrical energy by the silicon cells. This is the primary source of output in most installations.
Bifacial Rear Capture: Reflected and diffused light can be absorbed from the rear side. This helps increase production where reflective surfaces are present.
Temperature-Stable Operation: The module is designed for -40 to 85°C operating temperatures. A low power temperature coefficient supports better output in hot conditions.
