Agrivoltaics installation trends by region in Japan

In Japan, the number of agrivoltaics installations has gradually increased since 2013, but there are regional differences. 

Chiba Prefecture is the birthplace of solar sharing, and the number of installations has been increasing there and elsewhere.

From there, it began to spread to the Kanto region, where there are players who are enthusiastic about the solar sharing business, and installation is now underway in Shizuoka and Gunma prefectures.

There are more installations in eastern Japan than in western Japan, and more installations on the Pacific side than on the Sea of Japan side because of better sunlight conditions.

In recent years, grid connection constraints for renewable energy power plants have become a major social issue, and projects are concentrated in the Kanto region, where there is relatively more room for growth.

70% of new solar sharing applications in 2018 were in the Kanto region. 

Since Japan has a strong tendency to be precedent-based, I assume that the spread of this type of system will be further promoted in areas where the number of installations is increasing.
