Summary of Survey Results

Compared to last year's ranking, Hanwha Japan's significant advancement stands out. While Choshu Sangyo and Canadian Solar held top positions in the first half of 2025, Hanwha Japan's market share rapidly expanded from the autumn onward. The background for this is believed to be the introduction of a new panel with top-class domestic power generation efficiency, released 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 third this time as well.

During this period, contract timing tends to be delayed as people wait to assess subsidy trends. This year, cybersecurity requirements have been incorporated into the DR subsidies for storage batteries, which could affect the selection of solar panel products, and future trends are being closely watched.
