招待講演テーマ
「Estimation of the Potential for Photovoltaic Power Generation in the Residential Areas of Japan」
要旨
The nuclear power plant accident that arose from the Great East Japan Earthquake (2013) has become an opportunity to consider a new power supply method in Japan. Therefore, photovoltaic power generation, which can also be performed at ordinary households and has low environmental risks, is gaining attention. Against such a backdrop, this study aims to develop an estimation method for installing photovoltaic power generation in ordinary homes using GIS (Geographic Information Systems) in Japan.
The conclusions can be summarized in the following three points: 1) This method determines the profit and loss and payback period in order to evaluate the installation of photovoltaic power generation, taking in account the price of equipment, solar battery module conversion efficiency, subsidy, electricity purchase price, service life and rate for selling electricity. 2) The developed estimation method was applied to Kanagawa Prefecture in Japan, providing plural scenarios. Using a solar battery module conversion efficiency of more than 15%, it is possible to make the payback period shorter than the 20-year service life and anticipate a profit in almost the whole area. 3) In the regions of the south part where a subsidy is not provided or the amount of the subsidy provided is small, the profit is small and the recovery period is long compared to other regions. In such regions, it is necessary to adopt measures to increase the subsidy and install particularly small-capacity photovoltaic power generating systems in specific places in areas where subsidies are not provided in enough amounts.
