With a high feed-in-tariff (FIT) rate, Japan emerged, in the early 2000s, as a leader in solar energy and has since maintained installations of around 5 GW per year. Today, though, land for these projects is scarce and solar is beginning to come into conflict with agriculture and other industries.. .
Further legislation, introduced at the beginning of April, should serve to drive even more commercial PV installations. Revisions to Japan’s Energy Conservation Act now require. .
Incentives for new solar installation are also appearing at regional level and are primarily focused on rooftop PV. Since 2020, the city of Kyoto has had requirements in. .
With these FITs and other subsidies available, as well as rising electricity prices and an attractive power-purchase-agreement business model, new rooftop PV is expected to drive higher installation numbers across. [pdf]
