[HCG23-06] The impact of climate change on photovoltaic power generation in Japan

*Shobayashi Narin1 (1.University of tsukuba)

Keywords:climate change, renewable energy, photovoltaic generation

Renewable energy is playing an increasing role as a mitigation measure for climate change and global warming. In particular, photovoltaic power generation is attracting attention not only from the perspective of large-scale development, but also as a distributed energy resource for on-site consumption and local production for local consumption in close proximity to consumers, including individuals. However, photovoltaic power generation is a method of power generation in which the amount of power generated is largely dependent on the amount of solar radiation at the location and the temperature of the panels, and future climate change is likely to change the amount of power generated and the locations suitable for power generation from what they are today. We used MIROC5, a climate model, to evaluate how the future photovoltaic potential in Japan will evolve. The results show that PV potential is more likely to increase due to increased solar radiation than to decrease due to rising temperatures caused by global warming, and that PV potential will increase nationwide to varying degrees, especially in the Chugoku region and the northern Tohoku region. However, it should be noted that it is difficult to say that a particular site is suitable for the installation of large-scale solar power plants (mega-solar power plants), as it is necessary to consider various aspects such as the availability of sufficient land, ground stability, and ease of transmission to large-scale demand areas, in addition to the climatic conditions at the site.We hope that the results obtained in this study will serve as a reference for development guidelines for the national government and local governments that are striving to promote photovoltaic power generation, as well as for businesses that are planning photovoltaic power generation projects.
