Model SEG-575-BTA-BG | N-Type TOPCon | 144 Half-Cell | Bifacial | 1500V System Voltage
The SEG Solar SEG-575-BTA-BG 575W N-Type TOPCon bifacial solar panel is designed for projects that demand high performance and long term reliability. As part of the YUKON N Series, this advanced module combines N-Type TOPCon cell technology with a bifacial double glass design to deliver excellent energy yields on commercial, industrial and utility scale systems. With up to 22.26 percent front side efficiency and bifacial gains from the rear, more power is produced from the same roof or ground area. A robust 15 year product warranty and 30 year power warranty support long term investment security for owners and developers. The panel is engineered around 144 half cut monocrystalline cells, which help reduce resistive losses and improve performance under real world conditions. Its 1500 volt system rating, low temperature coefficients and durable double glass construction make it suitable for demanding climates and large string designs. This versatile panel suits rooftop arrays, carports and ground mount systems where dependable high output is required.
High power density for space constrained sites: A 575 watt output and up to 22.26 percent efficiency allow more generation from limited roof or ground space, helping reduce balance of system costs.
Bifacial design boosts energy yield: The bifacial construction captures light from the rear side, which increases total energy production over the module lifetime, especially on reflective surfaces.
Stable performance in hot conditions: Low temperature coefficients for power and voltage help maintain output during high temperatures, keeping production closer to the rated power on hot days.
Long term reliability and extended warranties: A 15 year product warranty combines with a 30 year linear power warranty that guarantees 87.4 percent output at year thirty, supporting bankable project returns.
Robust mechanical design for harsh sites: Double glass construction, anodized aluminium frame and IP68 junction box enhance durability against moisture, dust, sand and challenging environmental conditions.
This module converts sunlight into usable DC electricity through high efficiency N-Type TOPCon monocrystalline cells. Each of the 144 half cut cells is interconnected to create a high power, low loss circuit that operates efficiently across a wide range of irradiance and temperature conditions. The front glass receives direct sunlight, while the rear glass collects additional reflected light from the ground, roof or surrounding surfaces. This bifacial effect increases total energy harvested over the year. The module connects in strings to a compatible solar inverter, which converts the DC power into AC electricity for on site consumption or export to the grid. Integrated junction boxes, diodes and connectors ensure safe, low loss operation throughout the system lifetime when properly installed and maintained.
N-Type TOPCon cell technology: N-Type TOPCon cells use advanced passivated contacts to reduce recombination losses and increase cell efficiency. This structure helps maintain higher output over time, with lower degradation compared to many conventional P-Type cells.
Bifacial double glass construction: The panel features glass on both sides, protecting cells while allowing light to enter from the rear surface. When installed over bright or reflective surfaces, the rear side generates additional power, improving system energy yield without increasing array footprint.
Half-cell, high voltage system design: Half cut cells reduce resistive losses and improve shade tolerance within each module. The 1500 volt system rating allows longer strings, which can lower cabling, combiner and infrastructure costs on large commercial and utility projects.
