Abstract

The aim of this paper is to provide recommendations for the environmental policy regarding to the residential photovoltaic power systems in Japan. This study investigates how consumer's preferences take precedence in the dissemination of residential photovoltaic power generation. We use a conjoint analysis which has five measurements; feed-in tariffs in terms of an explicit monetary reward, capital subsidies, a product assurance program, costs of installation, and a CO 2 payback period. Following results clarify. 1) The capital subsidies for the residential photovoltaic power systems are supported by all consumer groups compared with other factors, and strongly by the older people (over 60 age). 2) The policy for feed-in tariff is supported by the respondent group which strongly concerns economic interest and by the younger people (under 60 age). 3) Therefore it is preferable to continue the current subsidy system because it could be a strong incentive to promote the implementation of a photovoltaic system. Different combinational policies of the capital subsidies and the feed-in tariff applied to the different consumer groups could be effective to expand installation photovoltaic systems.
