This paper presents analysis of the characteristic of persons who have installed residential photovoltaic generation, and factors that led to install. Especially, we focused on the difference between the persons who had the installation intention but not installed yet and the persons who had already installed photovoltaic generation. The questionnaire surveys were conducted to compare both persons.
As a result of the analysis, the following were clarified.(1)The persons who had installed photovoltaic generation were shifting from an ardent demographic to a general one. This reason depends on measures for spread of photovoltaic generation having changed in the age.(2)The installation intention was related to the recognition of benefit of photovoltaic generation and the installation action was related to the recognition of cost burden of photovoltaic generation. The information on the Internet and books were extracted as factors that stimulated the recognition of cost burden. Government subsidies, information on the Internet, and communication among familiar persons were extracted as promotion factors that led to the installation action of photovoltaic generation.
