59　Calculation of PV Installation Potential for Planted Forests and Extraction of Suitable Sites using the Hierarchical Analysis method (AHP method)

Abstract

Photovoltaics (PV) must become the main source of electricity to achieve carbon neutrality. In Japan, where flat land areas are scarce, new installation methods and locations need to be secured for further additional introduction. On the other hand, many plantations are neglected in Japan. These cause various problems, such as destruction of vegetation. Therefore, in this paper, the potential for PV installation in planted trees in Fukui Prefecture was extracted for large-scale PV plants, using a geographical information system (GIS) for visualization. The results showed that approximately 20% of the forests in Fukui Prefecture have potential for PV installations. Furthermore, buffering outside the PV installations could be expected to restore semi-natural grasslands.
