What does TOPCon mean in solar technologies?

TOPCon (Tunnel Oxide Passivated Contact) is an advanced solar cell technology that improves efficiency by reducing energy loss and increasing power generation. A residential TOPCon solar panel delivers higher energy output, better low-light performance, and long-term reliability, making it an excellent choice for homeowners looking to maximise solar savings.

How would I benefit from choosing TCL Solar TOPCon panels?

TCL Solar TOPCon panels deliver significant benefits over PERC technology, producing more energy through higher efficiency, lower annual power degradation, better performance in high temperatures and low light conditions. They also offer enhanced reliability, and more efficient bifacial production, leading to more power generation per square meter, better value over the long term, and excellent reliability for installations in harsh environments. With superior performance in all operating conditions, TCL Solar TOPCon sets a new benchmark for high-efficiency, future-proof solar technology.

What are the advantages of TCL Solar TOPCon panels?

Higher efficiency, with TOPCon cells in mass production reaching over 25%, a strong improvement over PERC that results in higher power output and better energy yield for the same installation area. Lower degradation, with lower first-year and slower long-term annual degradation for more consistent generation over the panel's 30-year lifetime. Enhanced durability, as the thin oxide layer protects against moisture, temperature fluctuations and environmental stress. A lower temperature coefficient that maintains higher efficiency in hot conditions, especially valuable in sunny regions and peak summer months. Superior bifacial performance from a higher bifaciality rate, capturing more reflected and diffuse light for greater total yield in commercial and utility-scale installations. Improved low-light performance during early mornings, late afternoons and cloudy days, extending daily production. And cost-effective manufacturing that uses existing PERC lines, reducing capital investment and supporting widespread adoption.
