RTS Corporation has published a video presentation summarizing the key findings of its report “Forecasting PV Installed Capacity in Japan 2025 to 2040” on YouTube.
The report presents the latest long-term forecast of PV installed capacity in Japan toward FY2040, based on the Seventh Strategic Energy Plan approved by the Cabinet in February 2025.
It covers two scenarios: the Business as Usual (BAU) scenario, in which PV accounts for 23% of the energy mix, and the Accelerated (ACC) scenario, in which PV accounts for 29%. Both take into account expected changes in policy, markets, technologies and prices.
The video is also embedded on our Publications and Databases page, where the summary PDF and the order form are available.
