Japan Solar Update: No.185 (Jan 26 – 30, 2026)
PV installations under the FIT/FIP schemes are projected at around 2 GW, clearly highlighting the need for further expansion of solar deployment through PPAs and other non-FIT/FIP models.
<Key points>
- As of June 30, 2025, cumulative approved capacity of PV projects was 7 4.4 GW, a 0.1 GW drop from the data as of March 31, 2025, as the approval cancellation of the projects under the approval cancellation scheme has continued. Cumulative commissioned capacity as of June 30, 2025 was 71.3 GW, with a slower growth of 0.3 GW. The overall commissioning rate increased to 96%
- For the quarter from April to June 2025, by capacity range, commissioned capacity of< 10 kW projects was the largest with 168 MW, followed by 10 – < 50 kW PV projects with 53 MW, 1 – < 2 MW projects with 42 MW, and 50 – < 500 kW projects with 32 MW
- In the first six months of 2025, from January to June 2025, the commissioned capacity was 1,346 MW. If this pace continues, it is estimated that the PV installed capacity in Japan under the FIT/FIP programs in 2025 will be around 2 GW
- The expansion of PV deployment via PPAs or other models, independent of the FIT/FIP programs, is required
