Status of deployment and potential of solar power (GW)

Japan has significant potential for solar power generation. Installed capacity stood at 73.8 GW (as of March 2024), compared with the 2030 targets of 103.5 to 117.6 GW. The recent deployment rate of 5 GW/year is about half of the peak level of 9.4 GW/year. The Japan Photovoltaic Energy Association has set its own target of 400 GW by 2050.
