The highest-rated power level improved from 720 W in January to 730 W in June 2025, represented by Huasun’s HJT module
The second-highest power rating remained unchanged at 715 W throughout H1 2025
The 710 W category stayed steady, with Jetion Solar joining Grand Sunergy in this tier in June 2025
The TaiyangNews TOP SOLAR MODULES Analysis H1-2025 looked into efficiency improvements across different technologies. Similar to efficiency, we also examine the products in the top 3 power levels. The highest rated power in the TOP SOLAR MODULES listing improved from 700 W in January 2023 to 730 W in June 2025, a 30 W absolute increase over 2.5 years. In the first half of 2025, this top rating improved from 720 W in January to 730 W in June, representing the biggest half-year gain since 2023. The 2nd highest power level remained unchanged at 715 W throughout the period. The third tier, which had reached 710 W in late 2024, also held steady during H1 2025. However, it saw a shift in representation, with Jetion Solar joining Grand Sunergy in offering 710 W modules. Overall, the first half of 2025 showed continued upward momentum at the top end of power ratings, driven entirely by HJT and TOPCon technologies.
In 2024, the top power level increased modestly from 715 W to 720 W in August and stayed at that level through the end of the year. The 2nd rank also saw a gain in the same month, moving from 700 W to 715 W. The third tier started at 695 W, increased to 700 W also in August, and was further raised to 710 W in October, maintaining that figure for the rest of the year.
In 2023, the highest power level held steady at 700 W until September, when it increased to 715 W. The 2nd rank began at 690 W and improved to 700 W by the end of the year. The 3rd rank opened the year at 685 W, dipped to 675 W mid-year due to product reshuffling, and recovered to close at 695 W in December (see High-Power Modules In TOP SOLAR MODULES Analysis).
Going into product-wise development details, the top power slot saw a major upgrade nearing the tail end of H1 2025. In June, Huasun raised the benchmark for the highest power output in the TOP SOLAR MODULES list by commercializing a 730 W HJT module, up from its previous 720 W product launched in August 2024. This marks the highest-rated power seen so far in the listing. The 2nd rank remained unchanged during this period, jointly held by Trinasolar and Tongwei Solar, both offering 715 W modules based on TOPCon and HJT technologies, respectively. As for the 3rd rank, while the power rating of 710 W remained the same as in late 2024, there was a notable change in representation. Jetion Solar entered the listing in June 2025 with its first HJT module rated at 710 W, joining Grand Sunergy in this power tier (see Technology Shares In Solar Module Efficiencies).
In 2024, Huasun and Tongwei Solar shared the top power spot at 715 W at the beginning of the year. This changed in August when Huasun introduced its 720 W HJT module, becoming the sole leader. Tongwei Solar’s module, unchanged in specification, was moved to the 2nd rank. Risen and Trinasolar, each with 700 W modules, had occupied the second tier earlier in the year. With the shift at the top, Risen’s 700 W HJT module and Trinasolar’s 700 W TOPCon product were jointly pushed to 3rd place. In October, Grand Sunergy entered the listing with a 710 W HJT module, becoming the sole occupant of the 3rd rank and maintaining that position through the end of 2024 .
The year 2023 saw more frequent changes. Huasun began the year as the top power holder with a 700 W HJT module. Risen joined in June with an identical 700 W module, sharing the top position until September, when Huasun upgraded to a 715 W HJT module. In December, Tongwei Solar matched this with a new HJT product, resulting in a shared top rank. The second slot initially featured Akcome’s 690 W HJT module. This was later replaced by Risen and Trinasolar’s 700 W modules following Huasun’s upgrade. Akcome then moved to the third tier. Grand Sunergy had not yet entered the list. The 3rd rank fluctuated mid-year, beginning at 685 W, dropping briefly, and then being represented by Akcome’s 695 W module in December.
