Summary of Survey Results

Compared to last year's ranking, Hanwha Japan's significant leap stands out. In the first half of 2025, Changshu Sangyo and Canadian Solar dominated the top positions, but Hanwha Japan's market share rapidly expanded from autumn onwards. This is likely due to the introduction of new panels with top-level power generation efficiency in Japan, launched around the same time.

In the Tokyo market, AIKO Solar, which is compatible with the metropolitan government's additional subsidies, continued to expand its share from last year, ranking 3rd again this time.

During this period, contract timing tends to be delayed as people assess subsidy trends. This year, requirements for cybersecurity measures have been included in DR subsidies for storage batteries, which could potentially affect the selection of solar panel products, making future trends noteworthy.
