Thornova Solar TS-BGT54 420–440W N-Type TOPCon Bifacial Dual Glass Solar Panel
TS-BGT54 | N-Type TOPCon | 108 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Thornova Solar TS-BGT54 420–440W N-Type TOPCon Bifacial Dual Glass Solar Panel represents the pinnacle of modern photovoltaic engineering. This advanced module delivers up to 440 watts of peak power with an industry-leading efficiency of 22.53%. Its unique bifacial design captures sunlight from both sides, boosting total energy yield by up to 25% from the rear. The N-Type TOPCon cells eliminate light-induced degradation naturally, ensuring stable performance over decades. Built with durable dual glass, it withstands extreme wind and snow loads while resisting microcracks. With a 30-year linear power warranty, this panel guarantees at least 87.4% output retention after three decades. Ideal for residential, commercial, and industrial projects seeking maximum efficiency and long-term reliability.
Key Benefits
Bifacial Energy Boost: Captures up to 25% additional energy from the rear side using reflected light.
N-Type Reliability: Eliminates light-induced degradation naturally for consistently higher power output.
Dual Glass Durability: Resists environmental stress, PID, and microcracking with superior glass construction.
30-Year Warranty: Guarantees 87.4% power retention after 30 years with linear performance protection.
Low Thermal Coefficient: Industry-leading -0.29%/°C coefficient minimizes efficiency loss in high heat.
How It Works
This solar panel operates through advanced N-Type TOPCon technology combined with bifacial dual-glass design. The front side absorbs direct sunlight, while the rear side captures reflected light from surfaces like concrete or snow. This dual-sided exposure significantly increases total energy harvest compared to traditional single-sided panels. The N-Type cells prevent light-induced degradation, maintaining high electron mobility and efficiency over time. The half-cell configuration reduces resistive losses and improves shade tolerance, ensuring consistent power even in partial shading conditions.
Bifacial Light Capture: The rear side collects reflected photons from surrounding surfaces, adding up to 25% more energy. This dual-sided mechanism maximizes yield in high-albedo environments like snowy fields or light concrete roofs.
N-Type Cell Stability: N-Type cells inherently resist light-induced degradation, ensuring no power loss from LID. This stability allows for higher electron mobility and sustained efficiency throughout the panel's entire lifespan.
Half-Cell Optimization: Each of the 108 cells is cut into halves, reducing resistive losses by half. This design enhances shade tolerance and lowers operating temperatures, improving overall energy output and reliability.
