The advantages of shingled TOPCon panels include:
Higher Efficiency 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.
Cooler Operating Temperatures 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.
Extended Panel Lifespan Reduced heat and lower thermal stress help minimize long-term power degradation and improve reliability over the panel’s lifespan.
Improved Shade Tolerance 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.
Enhanced Mechanical Strength Smaller cells experience less mechanical stress, lowering the risk of micro-cracks and improving durability during transport, installation, and operation.
Maximized Active Area 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.
Flexible Inter-Cell Connections Advanced flexible interconnections improve resistance to temperature swings, reduce the risk of ribbon failure, and enhance reliability.
Tested beyond industry standards for thermal cycling, shingle panels ensure reliability in the field.
By combining N-type TOPCon cells and shingled design, shingled TOPCon panels deliver higher efficiency, cooler operation, and exceptional long-term reliability—engineered for maximum performance in real-world conditions.
