This paper aims to identify the factors affecting the installation of residential solar photovoltaic (PV) in housing estates in Kakegawa City, Shizuoka Prefecture. The analysis of 1,327 houses in housing estates revealed that houses that were lower, fully rebuilt, newly constructed, larger as well as newly constructed were more likely to have PV installed. Furthermore, comparing to houses in adjacent blocks, the analysis of 1,971 houses showed that houses without building agreements, that were lower, fully rebuilt, newly constructed, smaller as well as newly constructed were more likely to have PV installed. Based on the results, full reconstructions, new constructions, building heights and property areas were suggested as factors affecting PV installation.
