The highest rated module power reached 730 W in June 2025 and remained unchanged through December, a 15 W increase over the last 2 years
The second-highest power rating largely remained stable at 715 W, with a brief increase to 720 W in October 2025, before reverting to 715 W
The third rank followed a similar pattern, holding at 710 W for most of 2025, briefly increasing to 715 W in October, and improving overall from 695 W in early 2024 to 710 W by the end of 2025
While efficiency remains the core metric of the TOP SOLAR MODULES analysis, module power is equally important. In addition to tracking efficiency progress, the TaiyangNews TOP SOLAR MODULES 2025 analysis therefore also examines developments in the top 3 module power ratings, focusing on changes at the top end and across defined power classes.
The highest rated power in the TOP SOLAR MODULES listing remained unchanged at 730 W throughout H2 2025. After reaching this level in June, the top power rating held steady from July through December. In the first half of 2025, this top rating largely remained flat from the beginning till May at 720 W, then increased to 730 W in June. 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. Overall, the highest rated power improved from 700 W in January 2023 to 730 W by December 2025.
The second-highest power rating in the TOP SOLAR MODULES listing remained largely unchanged during H2 2025. From July through September 2025, this power rank remained at 715 W. In October 2025, the second-highest power level was increased to 720 W, briefly narrowing the gap with the highest. However, this increase was short-lived, as by November the second-best power had reverted to 715 W, which remained at this level for the rest of the year and a major portion of H2 2024. However, 2024 started at 700 W and increased to 715 W in August, the only change in the 2nd power rank for the year. In H1 2025, the second-highest power level remained unchanged at 715 W throughout the period (see Solar Module Power Developments).
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. For the 24-month evaluation period, the second power ranking ranged between 700 W and 715 W.
The 3rd power rank closely followed the development trend of the 2nd rank. It started at 710 W in H2 2025, the same level it attained in October 2023, and also spiked to 715 W in October 2025, but reverted to 710 W the very next month. For the first half of the year, this power rank stayed unchanged at 710 W. In 2024, it started at 695 W and changed twice – to 700 W in August and 710 W in October. Interestingly, all 3 top ranks gained 15 W when comparing the start and end of the evaluation periods.
