This study aims to develop an economic evaluation method for installing
photovoltaic power generation in ordinary homes using GIS (Geographic
Information Systems). 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 into
account the price of equipment, solar battery module conversion efficiency,
subsidy, electricity purchase price, service life and rate for selling
electricity. 2) The proposed evaluation 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) The areas suitable for photovoltaic power generation are
Kawasaki City and Ninomiya-machi. It is necessary to adopt measures to increase
the subsidy and install photovoltaic power generating systems in specific
places in areas where subsidies are not provided in enough amounts.
