HJT module power increased from 700 W in early 2023 to 715 W by year-end, with Huasun further raising it to 720 W in August 2024
TOPCon module power advanced from 685 W in early 2023 to 700 W in September, with Trinasolar setting the highest rating for this category
IBC module power improved from 590 W in early 2023 to 620 W in June and further to 655 W in May 2024, led by AIKO
Unlike efficiency, power has no direct relevance to the performance of the cell technology. But it definitely provides insights into technology and product positioning, especially on the application front. The TaiyangNews TOP SOLAR MODULES Analysis 2024 highlights power developments across different high power wattage classes and different cell technologies (see TOP SOLAR MODULES: Progression Of Power Ratings).
Being the power leader also qualifies HJT for first mention. At the beginning of 2024, Huasun and Tongwei’s 715 W products shared the top position for power in the HJT stream. In August, Huasun raised the bar by introducing a 720 W module, securing the top position exclusively through the end of 2024.
At the beginning of 2023, Huasun’s HJT module led the HJT segment as well as the entire TOP SOLAR MODULES list with a 700 W power rating. In February 2023, Risen joined Huasun at the top with its own 700 W module, and both companies shared the top spot for the next 2 months. In September 2023, Huasun took the lead by commercializing a 715 W module, moving a step ahead. However, in December 2023, Tongwei Solar also commercialized a 715 W HJT module, resulting in both companies sharing the top spot (see Power Trends: High-Power Domination Continues In Solar Modules).
TOPCon technology represents the second-highest power rating. However, there was no change with respect to top power in this technology stream in 2024. Trinasolar’s 700 W TOPCon module was the leader throughout the year. The story was a little different in 2023, with several ups and downs. EGing PV’s TOPCon module was at the top at the beginning of 2023 with a 685 W power rating and retained its lead till June 2023. In July, as EGing PV reduced its module power to 580 W, the modules with the next highest rated power, the 625 W modules from Runergy and Suntech in this case, took the shared top spot. In August 2023, DAS Solar and JA Solar surpassed this by introducing modules with 630 W power, holding the top spot just for that month. In September, Trinasolar commercialized its TOPCon module with a power rating of 700 W, setting a new record for the technology. This 700 W power rating has remained the highest in the TOPCon category through December 2024.
While PERC comes 3rd in power, there was no major change for its top power throughout the last 2 years. A 675 W module from Canadian Solar has been leading the PERC stream in the power segment since the beginning of 2023. In the month of April, Risen also commercialized a PERC product with the same power rating, thus listing alongside Canadian Solar for the rest of 2023 and throughout 2024.
IBC, albeit an efficiency leader, stood last in power comparison. The top power of this technology changed only once during 2024 but by the same company. AIKO has also been the leader of the IBC power league with a 620 W product. Its record efficiency module included in May also brought an improvement in power, rated at 655 W. It was placed directly at the top among IBC modules and retained its lead till the end of the year. However, at the beginning of 2023, it was LONGi that had the lead with its 590 W top efficiency product at the time. Then in March 2023, AIKO’s ABC module series, featuring an even higher power of 610 W, took the title and improved the top power again to 620 W in June, which it retained till the end of 2023.
