TCL Solar shingled technology represents an evolution in solar panel design, combining N-type TOPCon solar cells with an innovative cell design to maximize efficiency, reliability, and real-world performance. In TCL Solar shingled technology, TOPCon solar cells are cut into smaller 1/3 strips and electrically connected in a shingled, overlapping configuration. This design eliminates inactive gaps between cells, increasing energy production and boosting overall panel output. The TCL Solar shingled TOPCon provides a premium solution, offering higher performance and enhanced reliability, particularly beneficial for installations with limited roof space or complex shading challenges.
Smaller 1/3-cut cells significantly reduce internal current and shorten the path electricity must travel within the panel. Lowering the internal current leads to a substantial reduction in resistive losses compared to full-size or even half-cut cells. This directly improves panel efficiency while also lowering operating temperatures—an important factor for long-term performance and durability, especially in hot climates. By integrating the smaller 1/3-cut TOPCon cells with advanced shingled design, TCL Solar shingled TOPCon panels deliver higher efficiency, cooler operation, and outstanding long-term reliability for real-world performance.
The advantages of TCL Solar shingled TOPCon panels include:
The smaller 1/3-cut cell design significantly lowers the internal current and shortens the path for the electricity to flow, resulting in lower resistive losses and improving efficiency.
Lower current helps to reduce the power dissipation in the form of heat. This simply means lower cell operating temperature, improving thermal performance in real-world and high-temperature installations.
Reduced heat and lower thermal stress help minimize long-term power degradation and improve reliability over the panel’s lifespan.
Smaller cells operate more independently, so shading on one area has minimal impact on the rest of the panel, reducing overall power loss in partially shaded conditions.
Smaller cells experience less mechanical stress, lowering the risk of micro-cracks and improving durability during transport, installation, and operation.
The shingled, overlapping cell layout eliminates inactive “dead zones” between cells, ensuring the entire panel surface is used to capture more sunlight and increasing energy production.
Advanced flexible interconnections improve resistance to temperature swings, reduce the risk of ribbon failure, and enhance reliability. Tested beyond industry standards for thermal cycling, SunPower Performance 7 panels ensure reliability in the field.
