Japan Solar Power Association: Increase Japan's solar power capacity to 300GW by 2050

The Japan Solar Power Association (JPEA) recently released the latest version of its long-term vision, PV OUTLOOK 2050, which sets a goal of introducing solar power in Japan by 2050.To meet the long-term goal of combating global warming set out in the Paris Agreement, about 30% of Japan's electricity needs will need to be generated from solar power by 2050, and the target is higher than before.

In JPEA's "PV OUTLOOK 2050" published in 2017, the target number for solar power generation by 2050 is 200 GW (connected output base).This is to meet the Japanese government's environmental goal of reducing carbon dioxide emissions by 80% by 2050.However, in the latest version of the release, the regular import target of 200 GW "is not enough to reduce the government target by 80 per cent" and is increased to 300 GW on the basis of networked output and 420 GW on the basis of solar panels.The 300 GW figure, which assumes maximum solar installations, is closer to achieving the government's "80% reduction target" due to advances in social electrification in multiple lead-in schemes.
The estimated installation location of 300 GW is 147 GW in demand areas (such as housing, non-residential buildings and industrial parks), with the remaining 153 GW assumed to be non-demand areas.
If the 300 GW is introduced, by 2050 solar will account for 31% of electricity supply, wind 15%, hydro 10%, renewables 7%, nuclear 11% and thermal 25%.This is assumed in the case of a wide number of introduced batteries.Assuming that 147GW will be installed in demand areas such as non-residential buildings and industrial parks, the remaining 153GW will become non-demand areas.
