Wedoany.com Report-Nov. 30, Japan's solar module shipments reached 1.28 GW in the first quarter of fiscal 2025 (April–June 2025), according to data released by the Japan Photovoltaic Energy Association (JPEA). Domestic deliveries totalled 1.273 GW, representing a 111 percent year-on-year increase, driven primarily by strong residential demand.
Residential installations surged 126 percent, while the non-residential segment grew 105 percent to 900 MW. This included 490 MW for large-scale power generation and 410 MW for general commercial applications. Overseas shipments remained limited at 6.5 MW.
Foreign manufacturers supplied 828 MW, accounting for 65 percent of total shipments and recording a 114 percent year-on-year rise. Japanese manufacturers delivered 452 MW, maintaining a 35 percent market share. Approximately 95 percent of all modules shipped were produced outside Japan.
Modules with rated output of 300 W or higher dominated the market, comprising 1.131 GW of the quarter's total volume.
Among domestic deliveries, foreign suppliers provided 411 MW for power generation projects, 285 MW for commercial systems, and 132 MW for residential use. Japanese companies contributed 241 MW to residential installations, 125 MW to commercial projects, and 80 MW to large-scale power generation.
The Southeast region continued to lead domestic installations. The results highlight sustained residential growth, ongoing expansion of utility-scale projects, and continued reliance on imported modules to meet rising demand.
Japan is supporting further solar deployment through new subsidy programmes that cover up to 75 percent of costs for next-generation perovskite modules and associated energy storage systems, aligning with national targets to develop 20 GW of perovskite capacity by 2040.
