One of the great advantages of TCL Solar Back Contact technology is its intelligent shade management. Thanks to the cell’s low breakdown voltage and unique architecture, each cell exhibits a built-in cell-level bypass diode function. In practice, this means a shaded cell can effectively bypass itself, reducing its energy consumption, while preventing major system-level power loss in partial shading. More importantly, this design minimises hotspot formation and supports more reliable long-term operation. For installations with intermittent or uneven shading—whether from vegetation, bird droppings, surrounding buildings, or dust, TCL Solar Back Contact provides a clear performance advantage.
TCL Solar Back Contact technology delivers more power by increasing conversion efficiency, supports higher reliability in real-world conditions, and provides a modern sleek appearance. With an elegant look and robust performance, TCL Solar Back Contact panel is a leading choice for next-generation solar installations.
The advantages of TCL Solar Back Contact technology include:
Better Temperature Coefficient: With a low temperature coefficient of –0.26%/°C, Back Contact modules outperform TOPCon in hot conditions, delivering over 1.3% more power at high operating temperatures.
Reduced Power Degradation: With an annual degradation rate of less than 0.35%, Back Contact modules retain 88.85% of their original power output after 30 years—1.45% higher than TOPCon.
Superior Shading Performance: Back Contact modules limit power loss to only the shaded area, reducing shading impact by up to 34% and delivering stronger performance in sites with moving or uneven shade.
Improved Microcrack Resistance: Full-backside continuous soldering and zero-busbar (0BB) design improve the module’s reliability under mechanical loads and temperature fluctuations.
Reduced Risk of Hotspot: Low breakdown voltage and uniform breakdown across the entire cell help reduce the dissipated power, protecting the module from hotspots and improving module reliability.
Lower Operating Temperature: Back Contact modules operate ~0.5°C cooler than TOPCon, leading to cooler operation in real world conditions and improving module longevity.
With industry-leading efficiency, intelligent shade management, and exceptional durability, Back Contact technology delivers higher-yield and more reliable modules—setting a new benchmark for solar industry.
