Data from the 2025 Mid-Year Certification Is Here! Have BC and TOPCon emerged victorious in the competition?
On October 15, 2025, at 17:08, the market reported that the National Quality Inspection Center (abbreviated as “CPVT”) is about to officially release the mid-year certification report for 2025. The reporting period for this certification spans from January 4 to June 30, 2025. The report highlights the operational performance of the first deep-sea certification base.
This certification integration involves various certification technologies and comparative analyses. It has verified the effectiveness of the certification technologies for solar energy generation under different environmental conditions, establishing a basis for promoting the certification standards and development of enterprises.
This certification report presents the results for two technology paths: BC and TOPCon. The selected products include the Hi-MO 9 series from BC and the TOPCon product series, with the following performance metrics:
- BC technology demonstrated significant electrical performance advantages over TOPCon.
- The Hi-MO 9 series consistently showed better performance across various electrical metrics.
- The performance advantage of Hi-MO 9 compared to TOPCon in terms of output power efficiency increased by 1.94% during the testing period from January to June 2025.
On February 4, 2025, preliminary test data indicated that the output power efficiency for the Hi-MO 9 series reached 0.98%, confirming that under specific conditions, it maintains superior electrical performance.
Comparative graphs show that during the testing periods, Hi-MO 9 exhibited greater stability in performance metrics compared to TOPCon.
In terms of consistency, the Hi-MO 9 series achieved a mean operational efficiency of 1.31°C, which is significantly lower than that of the TOPCon series, indicating a better longevity and performance reliability.
Additionally, under combined operational conditions, Hi-MO 9 achieved a maximum output power of 667.05W, surpassing TOPCon’s 648.11W, demonstrating stronger performance in practical applications.
Currently, the National Quality Inspection Center is actively developing certification standards based on strict scientific data and long-term testing results, aiming to enhance the selection and technological paths for marine-based solar products.
The certification results indicate that the HPBC 2.0 technology has shown remarkable performance under marine conditions, particularly in terms of stability during low light and weak sunlight scenarios.
As of now, the country is focused on the certification period for the marine solar products, and this certification will provide guidance for the future development of marine-based solar technologies.
