The rise of TOPCon PV Modules

In the ever-evolving world of solar energy, new technologies continue to set the standard. A recent study has shed light on the promising advantages of the latest generation of TOPCon (Tunnel Oxide Passivated Contact) modules. These innovative modules significantly outperform their earlier counterparts, such as PERC technology, in terms of energy yield. This makes them an excellent choice for solar installations.

A leap forward

The study, conducted over a three-month period, compared n-type TOPCon modules with a previous generation of p-type PERC modules. The newer TOPCon modules showed an impressive energy yield that was 5.69% higher than that of the older PERC modules. These results are not only encouraging but also significant for the industry as a whole.

Advantages of TOPCon PV Modules

Why are these new TOPCon PV modules a total gamechanger? There are several reasons that set this technology apart. 

  • Increased Energy Production: TOPCon outperforms PERC technology in terms of energy yield. The ability of TOPCon modules to generate more energy from the same amount of sunlight has a profound impact on solar installation performance. The higher energy yield means installations can produce more electricity, resulting in a quicker payback period.
  • Extended Lifespan: Experts emphasize that TOPCon modules offer superior performance in both the short and long term. With a sturdy and resilient design, these modules offer a long lifespan and minimal performance degradation over time. This means that users can rely on long-lasting and dependable energy generation. PERC modules also boast good longevity, yet their performance degradation might be quicker than TOPCon.
  • Enhanced Performance Ratio: A key advantage of TOPCon modules is their higher performance ratio. This ratio compares the effective energy yield with a prediction based on power levels and weather conditions. They have proven to achieve a high performance ratio, signifying that they generate more energy than expected, even under varying conditions.
  • Weather Resilience: Another notable benefit of TOPCon modules is their consistency in performance across diverse weather conditions. Whether it’s extreme heat, humidity, or other challenging factors, TOPCon modules have demonstrated their ability to maintain reliable energy output. PERC modules are also reliable but might exhibit a higher sensitivity to environmental changes compared to TOPCon.


In conclusion, the rise of TOPCon PV modules is a breakthrough in the solar energy sector. Their improved energy yield, extended lifespan, better performance ratio  and resilience under various conditions make them an appealing choice for both individual investors and large-scale solar installations. As the solar energy industry continues to evolve, technologies like TOPCon will undoubtedly pave the way toward a more sustainable and energy-rich future.
